Gut Matter: Will FMT Change How We Look at Disease Treatments?

Converting poop to pills was something unimaginable a few years ago, but now Fecal Microbiota Transplant (FMT) is taking the medical world by storm. This revolutionary technique, which promises to treat a wide range of diseases, from GI disorders to mental health issues, is becoming popular due to its success in treating recurrent clostridioides difficile infection (CDI), a serious infection that can damage the colon. FMT offers tremendous opportunities but also has challenges that players should consider if they want to thrive in this industry.

FMT is a procedure in which feces from a screened, healthy donor are transplanted into a recipient to balance the gut microbiota. This procedure can help treat certain infections and lessen the severity of some gut health issues.

Gut infections are usually treated using antibiotics, which can occasionally destroy beneficial bacteria. A 2000 study published in the Journal of Microbiology, a delayed open-access journal of the American Society for Microbiology, indicated that CDI recurring in around 15% to 35% of people is caused by antibiotics disrupting the gut microbiota and its balance (gut dysbiosis). Dysbiosis has been linked to several chronic illnesses, such as cardiovascular disease, inflammatory bowel disease (IBD), diabetes, and colorectal cancer (CRC).

FMT is highly efficient in treating recurrent CDI, with a cure rate of 90%, according to a 2015 study published in the American Journal of Gastroenterology. Numerous trials to understand the efficacy of FMT in treating conditions such as obesity, liver disease, ulcerative colitis, Crohn’s disease, Parkinson’s disease (PD), and IBS are underway. There are also some pre-clinical studies in progress to understand the potential of FMT in treating illnesses such as diabetes, skin issues, lung diseases, and autism.

FMT is showing promising growth

The human FMT sector is expected to grow at a CAGR of 5.1% and reach US$3.15 billion by 2031, according to a 2023 report published by India-based market research company The Brainy Insights.

The key factor influencing this growth is the rising incidence of GI disorders. According to the GI Alliance, a US-based network of gastroenterology providers, around 20 million Americans have chronic digestive disorders. Similarly, the CDC estimates that there are around 500,000 cases of CDI reported annually in the USA, and about 9% of elderly patients die within a month of contracting healthcare-associated CDI. All these have influenced the growth of FMT, which offers a promising solution to several conditions.

Other factors influencing the FMT sector growth are the rising patient awareness and interest in preventive healthcare and the emergence of effective probiotic strains.

There are several biotechnology companies currently involved in R&D and product development. Australia-based BiomeBank became the first company to get approval from a competent authority to market its FMT-based CDI solution called Biomictra Faecal Microbiota (colonoscopic, enema, and upper GI delivery) in November 2022. This was followed by the FDA approval of US-based Rebiotix-Ferring Pharmaceuticals’ REBYOTA (rectally administered) in the same month. Seres Therapeutics, a US-based company, has also received FDA approval for its orally delivered product Vowst (SER-109) for treating CDI in April 2023. Following Seres’ footsteps, Rebiotix-Ferring is now conducting trials to develop an oral alternative, RVX7455.

US-based Finch Therapeutics is another major company developing solutions presently undergoing phase-3 studies for diseases such as chronic hepatitis B and autism. Its solution, CP101, for treating CDI, has been discontinued.

The FMT sector is grappling with a multitude of pressing challenges

The FMT sector has the potential to treat numerous GI and other related disorders effectively. However, the business landscape is still marred by several challenges that players must consider.

Lack of consensus about policies is making development challenging

Regulatory hurdles are one major roadblock players face. The FDA currently regulates FMT as an unapproved biologic medicine. There is a lack of uniform guidelines for FMT, causing variations in processes, such as donor screening and processing.

The FDA took its first step toward FMT regulation in 2013. It released a set of guidelines removing the need for investigational new drug (IND) applications when FMT is used for treating CDI unresponsive to standard treatments if medical practitioners secure informed consent. However, this application is needed when FMT is used for other reasons, including safety studies.

The FDA drafted new guidance in 2016, which was finalized in November 2022. In this guidance, the FMTs acquired from stool banks are exempt from regulatory discretion. Also, the IND requirements will be waived if some conditions are fulfilled, such as getting informed consent from patients or authorized representatives and screening and testing stool under the supervision of competent healthcare professionals. There should also be no known potentially serious safety concerns, such as issues with improper handling or storage, or issues with administering product collection without the proper testing or screening. All these increase the procedural burden for healthcare practitioners. However, the FDA has indicated no regulatory policies for stool banks to reduce the administrative burden of private practice settings without the support of research staff.

Due to the significant variation in gut microbial composition among samples, FMT fails to satisfy EU drug classification requirements. Also, since human cells are not an active component of fecal matter, FMT is not covered by EU Directive 2004/23, which deals with the safety and quality of human tissues and cells. Therefore, the European Medicines Agency (EMA) has authorized the member states to regulate FMT however they see fit.

This lack of consensus has led to diverging regulatory policies, causing uncertainties for interested players and making developmental activities challenging, particularly in Europe. But despite this, many companies, such as Rebiotix-Ferring Pharmaceuticals, are making leaps in R&D.

Donor selection has social, ethical, and financial challenges

Another bottleneck that needs to be addressed is the availability and selection of suitable donors. There is a debate regarding whether the patient should know the donor or not. Also, the ideal donor should be free from chronic illnesses or infections and willing to donate. The donor is screened for obesity, antibiotic resistance, microbiome diversity, oncogenic potential, a history of antibiotic use, and risky behaviors such as drug abuse.

Stool banks require donors to follow several restrictions, such as maintaining BMI, abstaining from unhealthy eating habits such as spicy foods or saturated fatty acids, and avoiding travel to infection-prone tropical regions for an extended period. With that, donor dropout is high due to the considerable commitment needed, according to a 2019 study published in Gastroenterology, the official journal of the American Gastroenterological Association (AGA).

FMT implementation is also facing several social and ethical challenges with questions such as donor compensation, gender of the donor, donor and patient vulnerability, and commercial use of fecal matter.

Companies can launch educational drives targeted at patients and ideal donors to raise their awareness about FMT, tackle social resistance towards the procedure, and build trust with prospective donor candidates and patients. This can help reduce people’s reluctance to participate in FMT procedures.

The procedure remains risky, especially for vulnerable population

FMT is associated with an increased risk of transmitting infections such as Shiga toxin-producing E. coli (STEC) and enteropathogenic E. coli (EPEC) from the donor to the receiver. Immunocompromised patients are at a higher risk of developing side effects, according to a 2020 study published in Digestive Diseases and Sciences, a peer-reviewed journal. Similarly, a 2019 case study published in the New England Journal of Medicine, a journal of the Massachusetts Medical Society, showed a fatal infection contracted by an elderly immunocompromised individual following an FMT procedure.

Another challenge is the very few pediatric clinical trials, which makes it difficult for physicians to make the best judgments for when to initiate FMT therapy in children.

To tackle safety-related challenges, the FDA released safety advice in 2019 and 2020 regarding the possible risk of severe, potentially fatal infections associated with the procedure. Companies such as Boston-based OpenBiome have promptly modified their sample screening methodology to identify such infections.

Lack of studies on long-term effects

The lack of understanding of the long-term changes FMT can cause in a patient’s microbiota is another challenge. Several studies reveal that liver diseases, cancer, cardiovascular diseases, etc., can develop due to microbiota dysbiosis. Investment in R&D by interested and capable players can help medical professionals understand the long-term implications and complications of FMT and identify feasible solutions, which can pave the way for widespread treatment acceptance.

The sector’s future appears bright, underpinned by extensive development

FMT is a highly effective treatment for recurrent CDI. New developments have been taking place in many areas, such as administration modes, stool collection, and storage, and interested players can find opportunities in these areas. The FDA is also becoming more accepting of FMT-based treatments that show good results. This is shown by the approval of Rebyota and Vowst, both of which were more effective in reducing recurrent CDI compared to placebo in randomized controlled trials.

Stool banking and processing is another area ripe with opportunities for interested players. Conventionally, fresh stool is used for FMT, but this can increase the cost of the procedure. Stool banks are being developed to facilitate cost-effective and safe treatment. An example is OpenBiome, the USA’s first and biggest public stool bank. Stool banks can also make the standardization of stool processing and donor selection easier, according to a 2019 report published by the European Helicobacter and Microbiota Study Group.

Players can also form collaborations with healthcare professionals and research institutions to offer FMT treatments and support microbiome research. Many government organizations are also showing interest in the development of FMT therapies. The GBP500,000 grant awarded by the Biotechnology and Biological Sciences Research Council (BBSRC), a part of UK Research and Innovation, in 2022 to Norwich-based Quadram Institute (QI) to build and equip a new FMT research facility is an indication of this.

Investing in the development of FMT treatments can revolutionize the treatment of several diseases, and companies that can invest in research can gain a head start in the competition. Rigorous R&D is going on to develop FMT solutions for conditions such as obesity, depression, cancer, pediatric diseases, and autoimmune disorders such as Crohn’s disease.

A 2023 trial conducted by the US-based Emory University School of Medicine also showed that FMT can reduce the colonization of multidrug-resistant organisms in kidney transplant patients. Investigators believe more research in this field can help improve transplant success rates and decrease the chances of infection. Individual case studies have shown great improvement in cure rates for certain diseases, including mental health conditions, but more research is needed to present a solid case for product development.

EOS Perspective

FMT is gradually establishing itself as a promising solution for recurrent CDI and is expected to create waves in the treatment of numerous physical and mental health conditions despite facing several challenges.

Improvements in donor selection, early identification of certain conditions with better risk assessment, and increased treatment efficiency can be expected with ongoing research expanding the knowledge base of the medical community.

Experts are also looking into FMT’s potential as an adjunct therapy in treating diseases such as tuberculosis, and it is expected to open the door to interested players to create personalized and targeted FMT-based treatments for various diseases.

Studies are also being done to understand and substantiate the potential of gut microbiota to anticipate diseases such as IBD and CRC using AI (Artificial Intelligence) and ML (Machine Learning). ML can be used to identify biomarkers in the gut microbiota to aid in the early detection of CRC. These studies, when extended to FMT, are expected to help medical professionals identify ideal donors and improve treatment efficiency.

The Brainy Insights, in its 2023 report, predicts a growth in the probiotic infusion segment owing to the increasing studies on diabetes management. Therefore, competitive players interested in FMT can also diversify their portfolios by including consortia (multi-population systems with a broad spectrum of microbial species) and probiotic products that have the potential to offer regulated, standardized treatments. This can help them get an edge over their competitors.

Several oral FMT solutions are currently in phase-1 and phase-2 clinical trials, and many are geared toward treating conditions other than recurrent CDI. For example, US-based Vedanta Biosciences is developing FMT therapeutics for IBD, food allergies, solid tumors, etc. As research continues, it is expected that investigators will be able to identify the bacterial strains that can treat different diseases and isolate and mass-produce them, leading to a decrease in stool collection and processing and a reduction in stool transplant-related infections, but this development is expected to occur very far in the future.

Although marred by several challenges, FMT is well-positioned in the microbiome industry to obtain FDA approval and (with time) widespread acceptance. Right now, interested players can expect good returns by investing in oral FMT development, stool banking, and R&D.

Poop to Pills: Is FMT the Future of Veterinary Medicine?

Fecal Microbiota Transplant (FMT), the transfer of healthy gut bacteria from a donor to a recipient to treat a myriad of conditions, has been gaining traction rapidly in recent years. Though the human FMT market has stolen the spotlight, the animal segment is also quietly blooming as a niche area, presenting a unique business opportunity for enterprising players.

The global human FMT market, estimated at US$2.11 billion in 2023, is projected to reach US$3.15 billion by 2031 with a CAGR of 5.1% between 2023 and 2031, according to a 2023 report published by India-based market research company The Brainy Insights. The animal FMT market is undoubtedly smaller, but it is difficult to determine its exact size due to a lack of consistent data on exact use. Also, while the human segment has many players, such as UK-based Microbiotica, US-based Finch Therapeutics, and US-based Rebiotix, Inc., the animal segment has a few competitors, such as Amend Pet and AnimalBiome, both US-based companies.

Gut Matter: Will FMT Change How We Look at Disease Treatments?

Veterinary FMT is slowly but steadily growing

Increasing pet ownership is one of the most important factors influencing the growth seen in the veterinarian FMT sector. The American Pet Products Association (APPA), a Connecticut-based NPO, conducted a 2021–2022 National Pet Owners Survey, which found that 70% of US households own a pet, an increase from 56% in 1988 and 67% in 2019. A 2022 report published by HealthforAnimals, a Belgium-based global animal health association, indicated that owners are becoming more aware of their pets’ health needs. Similarly, a 2012 State of Pet Health Report released by Banfield Pet Hospital, a US-based veterinary hospital chain, has shown an increase in chronic diseases in cats and dogs.

The high incidence of diarrhea in pets also affects the FMT adoption rate. A 2008 report published in The Veterinary Record, a UK-based peer-reviewed journal, states that one of the most frequent causes of pet owners seeking veterinary care is acute diarrhea (AD).

Antibiotics are frequently used in the treatment of AD in dogs, 45% to 70%. The use of antibiotics in dogs can cause imbalances in the gut microbiota, leading to other diseases. This makes it essential to have a more holistic approach to managing pet diseases without disrupting their gut health.

The FMT sector is marred with several challenges

Though the FMT procedure offers many benefits, large-scale adoption still faces numerous challenges.

Empirical and scientific evidence is still lacking

A 2021 article published in Gut Microbes, a journal from the UK-based publishing company Taylor & Francis, indicated that the experimental information provided in preclinical FMT protocols is extremely uneven and/or lacking. The study suggested the reason for this is the lack of reliable guidelines for reporting requirements that would support efforts to replicate the study and, eventually, yield reproducible research. Many papers considered in the study lacked information on core aspects; for example, 92% had no reliable data about anaerobic conditions needed for FMT prep, and 49% had no information on efficient fecal material storage.

There is also currently minimal scientific information available in the field of veterinary FMT. Moreover, there is very little information on the therapeutic effectiveness of FMT in small animals such as dogs and cats, according to a 2016 article published in Veterinary Medicine (Auckland, N.Z.), a peer-reviewed journal. The article suggests that though adverse effects are limited in human patients, assessing whether the procedure is safe in animals is difficult.

Regulatory framework is in its infancy

Regulation is a bit complex in veterinary FMT. While there are not many specific regulations for veterinary FMT, the FDA considers FMT treatments used to prevent or treat diseases in animals as a new drug. Marketing new veterinary drugs in the USA without an approved or abbreviated new drug application is illegal. These require the manufacturer to submit information proving that a proposed generic medication is equivalent to an approved reference-listed drug (RLD) in terms of quality, safety, and efficacy. The lack of detailed clinical studies in the veterinary segment can slow down regulatory clearance. The Center of Veterinary Medicine, the US department approving drugs for pet animals, does not have any specific regulatory policy regarding the use of FMT either.

Veterinarians lack experience

Lack of technical expertise and procedural experience can also hinder FMT adoption. A 2022 study published in Topics in Companion Animal Medicine indicated that 71% of veterinarians had never performed FMT. These results were based on 155 responses from 13 different countries.

Risk of transmitting disease phenotypes is high

FMT can transmit disease phenotypes, including obesity and metabolic disorders such as diabetes, according to a 2020 study published in Medicine in Microecology, a peer-reviewed journal. Similarly, changes to the gut microbiota, such as exposure to antibiotics or the transfer of cecal material (fecal material from the bottom right quadrant of the cecum, a part of the large intestine), can affect disease phenotypes, such as an elevated risk of colitis.

Donor selection is difficult and pricey

The selection of an ideal donor is another challenge. The donor animal should be free from all kinds of parasites and pathogens and without any history of gastrointestinal diseases. Similarly, the donor should have no history of behavioral issues and should be of ideal weight. There should also be no history of antibiotic use within six months before the sample collection. Stool banks must thoroughly test the samples used for FMT, increasing procedural costs and hindering widespread acceptance and adoption of the technique among pet owners and veterinarians.

Numerous investment opportunities are available for interested players

Though veterinary FMT is still in its infancy, businesses still have several investment opportunities in this sector.

Focusing on extensive R&D

Veterinary FMT is a promising sector, but more research is needed to support product and service development. Since the current competition is concentrated on rigorous R&D, interested players capable of making risky research investments will likely gain an upper hand over their competitors.

The research so far has been promising, and the extensive R&D helps drive the market and build the necessary base for FMT to be recognized as a separate category for approvals. A 2022 study published in Frontiers in Immunology, a journal of the International Union of Immunological Societies, has indicated that several studies were conducted in the field of FMT from 2001 to 2021. This study analyzed key aspects such as donor selection, efficacy, and adverse effects. The incidence of minor and serious adverse effects after an FMT procedure was found to be 11.63% and 1.59%, respectively, while the overall efficacy was 76.88%.

The results from this study are promising, but they also indicate that more research is needed to understand and confirm the efficacy, safety, and quality of FMT treatments in animals. The FDA is more likely to approve these therapies with more robust evidence from newer studies, giving market players more opportunities.

Even though there is currently a lack of consensus or evidence-based standards regarding FMT dosage or donor screening for animals, a recently established international expert organization, the Companion Animal Fecal Bank Consortium, is developing guidelines in these domains. This can also be considered as a first step towards prompting FDA approval.

Developing the oral delivery route

Market players can find opportunities in developing FMT treatments administered through oral rather than nasoesophageal or rectal routes. Currently, the FMT delivery route is one of the critical bottlenecks in the more widespread adoption of the therapy.

Both nasoesophageal and rectal delivery routes are considered more efficacious but are associated with considerable risks. Nasoesophageal treatments use endoscopes that cause discomfort and aspiration and make it difficult to assess the colon mucosa or get mucosa tissue samples. In rectal FMTs, colonoscopes and anesthesia are involved, the latter often being a significant risk to the pet patient, deterring pet owners from choosing FMT. Both rectal and nasoesophageal routes are also associated with a risk of perforation, bleeding, infection, etc.

Conversely, the oral delivery route is generally preferred due to non-invasiveness and ease of use. However, oral FMT takes longer to reach the large intestine and has been perceived as less effective.

Market players can attempt to meet the preference for the oral route by building on a few research studies showing the good efficacy of oral FMT in pets. While research on animals is still limited, research in humans can be extended to identify approaches to improved efficacy of oral FMTs in treating animal GI infections. One such research was a 2017 study published in JAMA Network Open, an open-access journal by the American Medical Association, which indicated that in humans, oral FMT had efficacy in the treatment of C. difficile infection similar to that of rectal FMT.

One of the pioneers in this area is AnimalBiome, which developed an oral Gut Restore Supplement in an enteric-coated capsule (a coating that protects the medicine from the stomach’s acidic environment before it reaches the intestine and reduces side effects). The company conducted a pilot study in 2019 to observe the impact of the capsule on 40 dogs and 72 cats suffering from IBD. The study found that symptoms improved in 83% of the cats and 80% of the dogs. As the availability of such FMT solutions is still meager, there is plenty of room in the market for businesses to follow AnimalBiome’s footsteps and invest in creating oral FMT solutions.

Driving adoption through at-home administration kits

Another growth area for players is the development of user-friendly oral at-home administration kits for more straightforward treatment requirements. There is a demand for such easy-to-administer at-home solutions in the animal FMT space, as getting the pet to a vet is typically stressful for both the animal and the owner.

A 2011 survey published in the American Veterinary Medical Association (AVMA) journal indicated that out of 2,188 dog and cat owners polled, 38% of dog owners and 58% of cat owners said their pet “hates” visiting the vet. If FMT has to be repeated or spread over multiple visits, the treatment process is also time-consuming, further decreasing the likelihood of completing the therapy.

At-home application solutions can help make significant inroads into FMT acceptance, as pet owners are more likely to opt for such treatments rather than in-hospital procedures whenever possible.

Increasing specialization and targeted treatments

Developing more target FMT treatments (specific to animal breeds or conditions) appears to be a good area of opportunity. Currently, studies are being carried out to develop farm-specific FMT to treat various conditions in cattle.

A 2022 article published in PLOS One, a peer-reviewed journal, investigated the effects of farm-specific FMT on pre-weaned calves. The study indicated that FMT-treated calves’ alpha-diversity (indicating microbiota richness) had increased. It also suggested that the success of FMT will improve with proper criteria for donor selection. This offers scope for further investigation for market players to develop such targeted therapies.

Expanding through complementary products

Players can grow their FMT business by building a range of products to complement FMT therapies, such as specialized probiotics or microbiome health supplements.

A 2015 study published in BMJ Open, an open-access medical journal, has indicated that the gut microbiome can be strengthened and balanced in humans with the help of proper diet, probiotics, prebiotics, and FMT. Researchers are now looking into the positive impact of probiotics on animal health, such as improvement in digestion, lowered risk of gastrointestinal diseases, etc. With support from such research studies, players can work to offer comprehensive treatment and maintenance product lines.

Working on awareness through educational initiatives

Apart from immediate business opportunities, players might also have to get involved in activities that inform, educate, and help build the FMT market. Though it is a promising emerging therapy, very little information is available on veterinary FMT. In order to reap long-term rewards, businesses should spotlight and promote FMT and its positive effects on animal health to the vet community and the public by launching educational drives, conferences, and other similar initiatives. Existing players already recognize this need. For instance, Amend Pet, a major company in the veterinary FMT segment, has free educational courses in the form of RACE (Registry of Approved Continuing Education)-approved videos for veterinarians.

Increasing adoption through collaborations

Further, players in the FMT space should collaborate with veterinary hospitals and other organizations dealing with animal health to work with them and increase FMT adoption.

An example of this is the strategic collaboration between Amend Pet and the Association of Shelter Veterinarians (ASV) that started in May 2023. With this partnership, Amend Pet plans to offer easy-to-use and affordable FMT treatments to shelter dogs. The ASV has over 2000 veterinary professionals and 23 student chapters worldwide. Partnerships such as this can be expected to raise awareness about FMT among the public and veterinary sector, leading to improved adoption rates.

EOS Perspective

While veterinary FMT still has a long way to go before becoming a mainstream therapy, it is already an exciting field with many expected developments.

The spectrum of animal health conditions that can be treated or managed with FMT will continue to expand to include immune system disorders, metabolic conditions, and behavioral issues. Progress in the animal FMT space will likely be linked to research done in human FMT, as these studies can be extended to animal healthcare or at least be a starting point for animal FMT-specific research, revolutionizing veterinary treatments.

Improvements in donor selection processes, such as more stringent and advanced inspection of the donor’s gut microbial diversity and behavior evaluation, can be expected as many studies are now being done to understand the connection between behavior and gut microbes.

Rapid technological development, especially in AI, is expected to influence veterinary FMT as well. AI-powered equipment might be used for guided rectal FMT treatments to improve the procedures’ accuracy. This is likely to be safer for the animal and can prompt pet owners to choose FMT to treat their pet’s gastrointestinal issues. Companies investing in research can expect growth in this field.

All these developments, if accompanied by simultaneous partnerships between industry players and veterinary clinics, offer a promising future for the animal health FMT. The return on investment in this sector might not be immediate. For now, the industry needs to prioritize driving adoption, educating and disseminating knowledge, and gathering scientific data and empirical evidence to build a sound understanding of FMT in veterinarians, pet owners, and regulatory bodies. Nonetheless, the industry prospects are promising, and the players can expect the long-term benefits to be substantial.

A New Era of Vaccines – Will It Solve the African Malaria Issue?

Malaria, a treatable and preventable yet potentially fatal disease, is yesterday’s news in many developed nations. But this disease is still wreaking havoc in several developing countries, including the African continent. With the release of a new vaccine, many medical experts are examining whether this initiative will solve Africa’s malaria problem.

Africa’s crippling malaria burden has severe and lasting implications

Malaria is still a severe health issue in several countries, with the African region accounting for the lion’s share of the cases. WHO reported that in 2022, there were 249 million malaria cases, of which 94% were concentrated in Africa. Similarly, the number of deaths due to malaria was estimated to be 608,000, with 95% in Africa.

In the African region, about 78% of malaria-related deaths occurred in children under the age of five. Approximately half of malaria-related deaths were recorded in four African nations, namely Mozambique (4.2%), Uganda (5.1%), Nigeria (26.8%), and the Democratic Republic of the Congo (12.3%).

Malaria is mainly treated using artemisinin-based medicines. However, according to the WHO, partial artemisinin resistance is becoming a challenge in treating the disease in areas such as Tanzania, Rwanda, Uganda, and Eritrea. This has made developing a new solution to the malaria issue even more paramount.

New vaccines offer hope for eradicating malaria

In a significant effort to eradicate malaria from Africa, a new malaria vaccine has been introduced in the West African region in a first-ever routine vaccination program. Cameroon started the drive on January 22, 2024, by vaccinating children below the age of five with the RTS,S vaccine. Following the footsteps of Cameroon, many other countries have also opened their doors to this vaccine. Burkina Faso started the campaign on February 5. Similarly, Sierra Leone, Niger, and Liberia will also begin deploying the vaccine in late 2024.

UK-based pharmaceutical company GlaxoSmithKline (GSK) and PATH, a US-based NPO, developed the RTS,S vaccine after long clinical trials and tests. The initial version, which was developed in 1987 in GSK labs, underwent the Phase 3 trial between 2009 and 2014.

The RTS,S vaccine, commercially named Mosquirix, is designed to act against Plasmodium falciparum, a deadly malaria strain very common in the African continent, and prevent it from infecting the liver by targeting the circumsporozoite protein on the sporozoite surface. It was made by combining genes from the repeat (‘R’) and T-cell epitope (‘T’) of the pre-erythrocytic circumsporozoite protein (CSP) of the Plasmodium falciparum parasite with a hepatitis B virus surface antigen (‘S’). GSK researchers also used their expertise from developing the Energix-B vaccine against Hepatitis B to develop the RTS,S vaccine.

WHO has also pre-qualified another vaccine, R21/Matrix-M, developed by UK-based Oxford University and manufactured by Pune-based Serum Institute of India (SII), to prevent malaria. This vaccine is expected to be deployed in May or June 2024.

R21/Matrix-M functions similarly to RTS,S vaccine, but it is formulated to reduce anti-hepatitis B surface antigen antibody responses and raise anti-circumsporozoite protein antibody responses. Its initial focus was to induce a high degree of T-cell responses against pre-erythrocytic malaria antigens in the liver. But now, its focus also includes triggering high-level antibodies against the sporozoite stage of the parasite’s life cycle.

This vaccine also has the Matrix-M from US-based Novavax, a saponin-based adjuvant that boosts immune responses, enhances vaccine presentation in lymph nodes near the injection site, and increases vaccine durability and efficiency. This technology was successfully used in the COVID-19 vaccine produced by Novavax.

The new vaccines are effective in preventing malaria

Large-scale clinical trials have assessed the efficacy and safety of both vaccines. Also, in 2019, after the WHO accepted its advisory bodies’ counsel on malaria immunization, RTS,S was rolled out in a pilot program and closely observed within the initial Malaria Vaccine Implementation Programme (MVIP) in Malawi, Kenya, and Ghana. Around 2 million children were immunized during this drive. This helped experts assess the on-ground efficacy of the vaccine. A 2023 article published in Malaria Journal, a peer-reviewed open-access journal of BioMed Central, indicated that the pilot rollout of the vaccine demonstrated a roughly 30% reduction in the risk of developing severe malaria. R21/Matrix-M has a slightly higher efficacy. A 2022 study published in The Lancet, a peer-reviewed journal, indicated that R21/Matrix-M was 75% effective against both first and recurrent malaria cases following three vaccine doses over a 24-month follow-up period.

While both these vaccines are considered safe by experts, they have some side effects. In the case of the RTS,S vaccine, the incidence of serious adverse events (SAEs) and fatal SAEs was 24.2%–28.4% and 1.5%–2.5%, respectively, across all study groups, according to a 2019 article published in Human Vaccines & Immunotherapeutics, a peer-reviewed journal of Taylor & Francis. Also, 0.0%–0.3% of individuals self-reported experiencing SAEs as a result of vaccination. The common adverse effects reported in clinical studies were upper respiratory tract infections, pneumonia, and gastroenteritis.

In the case of the R21/Matrix-M vaccine, the common side effects reported in phase 3 trials included site pain (19%) and fever (47%). The phase 3 trial was conducted on around 4,800 children in Tanzania, Kenya, Mali, and Burkina Faso.

Some challenges await players willing to invest in the African vaccine landscape

Though the introduction of the new vaccines offers a glimmer of hope to eradicate malaria from African nations, several challenges are waiting for companies willing to invest in this sector.

The complex religious and social beliefs in Africa make vaccine acceptance difficult

One major bottleneck many players can face is the reluctance in African societies to accept the vaccines. This hesitancy is caused by numerous misconceptions and rumors spreading about both vaccines’ side effects, especially in rural areas. A similar issue happened in 2003 when five states in northern Nigeria refused the polio vaccine due to the fear that it rendered women sterile.

A senior immunization officer at Cameroon-based Value Health Africa said that conspiracies and myths regarding the malaria vaccines can be expected. In his opinion, understanding such dynamics in different communities and creating immunization drives accordingly will lead to a larger acceptance of the malaria vaccines.

Many African countries also lack the capability to track and record vaccine side effects, creating concerns about their safety and efficacy. This can also discourage people from receiving the shots.

Players can tackle this challenge by conducting awareness camps and education drives focusing on the positive effects of the vaccine and debunking the myths. Companies should partner with trusted community leaders, religious figures, and healthcare workers to address concerns directly. Also, developing culturally appropriate educational materials in local languages explaining the benefits and safety of vaccines can help build trust and encourage vaccine acceptance. Collaborations with international agencies such as WHO, UNICEF, and Gavi, the Vaccine Alliance, an international organization focused on improving vaccine access to children in poverty-stricken countries, can also increase the authority of these drives.

Infrastructural deficits in the African continent hinder vaccination storage and deployment

Vaccine storage and distribution are another bottleneck players can face. Many African countries face frequent power outages, poor road networks, and inadequate cold chain facilities, making it difficult to get vaccines and vaccinators to target communities. Lack of proper storage facilities can also severely hamper the potency of vaccines.

Also, neither of the malaria vaccines used in Africa are produced in the continent as of now. This adds to the transportation and logistics costs of the companies. Current market players are evaluating many strategies to reduce these costs to make immunization drives more profitable.

GSK, the producer of the RTS,S vaccine, is currently in talks with India-based manufacturer Bharat Biotech for technology transfer, owing to the country’s cost-effective vaccine production.

Similarly, SII is in talks with Nigeria and Ghana to produce the R21 vaccine locally. However, the lack of proper infrastructure and technical expertise makes it extremely difficult for the company to set up vaccine-producing plants in these countries. Currently, it is still profitable for players to mass produce malaria vaccines in other countries, such as India, and then transport them to Africa, even with the additional logistics costs.

Financial challenges are creating roadblocks to immunization drives

Funding is also an issue in vaccination drives. Substantial funding is typically needed for these programs. For example, according to a 2016 report published in Vaccine, a peer-reviewed medical journal published by Elsevier, the cost of the DTaP vaccine (diphtheria, tetanus, and pertussis) for a child in Africa can range from US$25 to US$45, without including other logistics costs and requirements. Also, in many African countries, the expenses of vaccination drives are typically paid for by outside donors and organizations. This can make the widescale rollout much more challenging.

EOS Perspective

The malaria vaccination drive is expected to dramatically change the way the African continent fights this deadly disease, especially with 30 countries expressing high interest in adopting the vaccine, according to the chief program officer at Gavi. Till now, the focus of companies and organizations such as WHO has been more on treating the disease, but with the release of the new vaccine, the focus has shifted towards preventing and eradicating the disease from the African continent.

With international organizations and NGOs pushing to expand the vaccination drives to cover the entire continent, the currently competing market players focusing on immunization are in for a huge profit. Players such as GSK, which started research on the vaccine in the 1980s, have years of research behind product development, placing them miles ahead of their competitors. Other interested and capable companies will have to put more effort into R&D to compete with these veteran players.

While only two vaccines have currently received WHO recommendation, several more candidates are in the pipeline, with many in their phase I-IV development. According to the WHO, 133 vaccines are currently under clinical development, and 38 out of them are in active status. An example is US-based biotechnology company Sanaria’s PfSPZ Vaccine, which proved to be easy to administer, well-tolerated, and safe in a small trial on Malian adults. Similarly, Germany-based BioNTech hopes to use its mRNA technology to create a malaria vaccine and launched the early-stage clinical trials in 2022.

Several competitive players now understand the investment potential in the malaria vaccine industry. Since 2002, 221 trials involving malaria vaccines have either been initiated or completed, according to the WHO. This means that competitive and able players who can make early investments in the market might become strong competitors in the near future.

Gavi has reported that, as of February 2024, just 18 million units of the RTS,S vaccine will be available to reach 12 nations through 2025. Though the actual vaccine requirement numbers are not yet known, since the continent is home to over 207 million children under the age of four, it can be safely assumed that the demand for effective vaccination will not decrease anytime soon.

Also, with the establishment of the African Medicines Agency (AMA) set up to create a uniform regulatory framework across the continent, it is likely to become easier for vaccine producers to enter the market, as the requirements, which currently vary from country to country, are expected to be more unified. Currently, 37 out of 55 African countries have ratified or signed the AMA Treaty, and this is likely to increase soon.

Studies are now being initiated to create an effective single-dose vaccine. A preprint of a study by European researchers from Germany, The Netherlands, and Switzerland jointly researching the single-dose vaccine and its effectiveness was released in bioRxiv, an open-access preprint repository owned by the Cold Spring Harbor Laboratory. However, this study is yet to be evaluated by the medical community.

All in all, joint efforts from international organizations such as WHO and pharmaceutical companies are expected to not only decrease the disease burden but also serve as a foundation for future research into more potent and long-lasting vaccines.

Anti-Obesity Drugs – Pharma Companies Race to Grab a Bite of the Pie

472views

For many years, bariatric surgery has been the go-to option for people struggling with obesity and obesity-induced conditions. However, for the last couple of years, another easier option has become available in the form of GLP-1-based weight loss drugs. This class of medicine mimics a hormone that helps reduce food intake and control appetite. These drugs have revolutionized the weight loss market, which was previously dominated by gimmicky and fad-based OTC solutions. Due to GLP-1’s proven effectiveness, there is soaring demand for these drugs, outstripping its current supply capacity. While only two players operate in this market, several leading drugmakers have been racing to develop their own version of the drug. Moreover, with additional proven merits of the drug beyond just weight loss, it has become more appealing for pharma players to invest in.

GLP-1 anti-obesity drugs make big waves in the pharmaceutical sector

Over the past few years, anti-obesity drugs have received immense attention from healthcare professionals, pharmaceutical companies, and the general public. A new class of medication that stands out is glucagon-like peptide-1 (GLP-1) agonists, traditionally used for treating Type 2 diabetes. But along with managing diabetes, these drugs also suppress appetite and lower calorie intake by mimicking the GLP-1 hormone (a gastrointestinal hormone), which causes the patient to feel fuller longer and thereby prevents overconsumption. Regular intake of such drugs is deemed to result in a weight loss of about 15-25% of body weight in obese people.

GLP-1 agonists received FDA approval as anti-obesity drugs in 2021. Given their promising results, the demand for these drugs has increased immensely. However, despite the patient’s high out-of-pocket price of US$1,000 plus, there are severe shortages in the market.

Only two players operate in this highly-coveted market

The GLP-1-based medication is now marketed in two categories – one for managing diabetes and blood sugar levels and the other as a weight loss drug. The GLP-1-based weight loss drug market is highly consolidated, as only two players operate in this space. These are Denmark-based Novo Nordisk and US-based Eli Lilly.

Novo Nordisk, the market leader, received FDA approval for its weight loss injectable, Wegovy, in June 2021. This drug uses the same active ingredient as Novo Nordisk’s diabetes drugs, Ozempic and Rybelsus (oral); however, it has a different dosage and can also be used for weight loss in patients who do not have diabetes. That being said, Ozempic has also been used off-label for weight loss.

On the other hand, Eli Lilly’s injectable drug for weight loss, Zepbound, received FDA approval in November 2023. Eli Lilly’s glucose-dependent insulinotropic polypeptide – GIP/GLP-1 injectable drug for diabetes, Mounjaro, has the same composition and dosage as Zepbound and is often prescribed off-label for weight loss as well.

While Novo Nordisk’s drugs, which use semaglutide as an active ingredient, result in weight loss of about 13 to 22 lbs, the drugs by Eli Lilly have tirzepatide as an active ingredient. They are stated to result in a weight loss ranging between 15 and 28 lbs.

From a price-point perspective, Wegovy has an out-of-pocket cost of US$1,349 per month, compared to Zepbound, which has an out-of-pocket cost of US$1,060 per month. Thus, while Novo Nordisk’s Wegovy has the first-mover advantage, Eli Lilly’s Zepbound is considered more effective and better priced.

Currently, both weight loss drugs by Novo Nordisk and Eli Lilly come in the form of injectables. However, both companies are developing oral versions of the drug as they are easier to administer and more convenient to prescribe. They may also help ease supply constraints currently impacting the injectables. In June 2023, Novo Nordisk conducted Phase 3 trials for its once-daily oral Wegovy drug, according to which the drug helped obese adults lose about 15% of their body weight. Similarly, in June 2023, Eli Lilly conducted Phase 2 trials for its oral GLP-1 receptor for weight loss. The drug helped obese adults lose up to 14.7% of their body weight. Both companies are optimistic about the outcomes of their trials; however, the expected launch timelines for these drugs have yet to be determined.

Leading drugmakers race to compete in the growing anti-obesity drug market

Currently, Novo Nordisk and Eli Lilly are the only two players operating in this market. However, several other leading pharmaceutical players have joined the race and are working towards developing their own version of the drug, either through in-house R&D or through strategic acquisitions.

Moreover, they are targeting their research towards developing and marketing a new generation of GLP-1-based medications that are administered orally, are longer lasting, and have additional health benefits and limited side effects.

In February 2024, US-based biopharmaceutical company Amgen successfully completed a Phase 1 clinical trial for its GLP-1 agonist drug, MariTide. As per the trials, the drug produced a 14.5% weight loss in patients administered the highest dose. Moreover, the company claims that the trial indicates that patients may need to take less frequent doses of MariTide (compared with current competition), and the weight loss achieved stays significantly longer. The company has begun its Phase 2 trial, with results expected by late 2024.

In December 2023, Swiss-pharmaceutical giant Roche acquired US-based Carmot for US$3.1 billion (US$2.7 billion upfront cash and US$400 million on certain milestones). This acquisition has helped put Roche on the map for obesity drug development. Carmot has two GLP-1 agonist molecules for weight loss, which are currently being tested in the mid to advanced stages of clinical trials. The first drug, CT-388, is a once-weekly injectable and has completed Phase 1 clinical trial, while the other drug, CT-996, is an oral drug currently undergoing Phase 1 trials.

In November 2023, UK drugmaker AstraZeneca entered into an agreement with Shanghai-based Eccogene, wherein the former licensed an oral once-daily GLP-1 receptor agonist called ECC5004 for the treatment of obesity, Type 2 diabetes, and other cardiometabolic conditions. For this, AstraZeneca agreed to pay Eccogene an upfront fee of US$185 million for the drug and a further payment of US$1.83 billion in future clinical, regulatory, and commercial milestones and tiered royalties. The drug is currently in Phase 1 development, and the company hopes to enter Phase 2 of clinical studies by the end of 2024. In the past, AstraZeneca stopped the development of two GLP-1 agonist drugs that were being developed in-house. The development of an injectable called Cotadutide was halted in April 2023, and an oral drug called AZD0186 was halted in June 2023 after their respective Phase 2b and Phase 1 clinical trials did not yield the desired results.

Pfizer, one of the most active companies in this regard, has faced multiple failures in their endeavor to develop a competitive obesity drug. In 2020, it started a clinical trial for its GLP-1 agonist weight loss drug, Lotiglipron. However, in June 2023, the company stopped developing the drug after its Phase 1 and Phase 2 drug interaction studies indicated a rise in liver enzymes in patients who took the drug once a day. In 2021, the company simultaneously began working on another GLP-1 receptor agonist, Danuglipron, which was to be taken twice daily. While the Phase 2a trial for the drug in June 2023 showed promise, the company halted the development of the drug post its Phase 2b trial in December 2023. The drug was scrapped as, despite significant weight loss, the trial patients experienced high rates of common gastrointestinal and mechanism-based adverse side effects. The company is now conducting a pharmacokinetic study with a once-daily version of the Danuglipron drug that will provide guidance on future development plans.

Pfizer’s failure with these two drugs demonstrates the struggle the leading pharma companies face to develop a safe, effective, and tolerable GLP-1 agonist for weight loss.

GLP-1 agonist drugs have benefits beyond diabetes and weight loss

Despite multiple setbacks, leading pharma companies are investing heavily in this space, as they understand the potential of these drugs. While currently, GLP-1 agonists are poised as diabetes and weight loss drugs, they have far more benefits. Data from ongoing clinical trials and independent studies suggest that GLP-1 agonists also help improve cardiovascular health and kidney function and help treat addiction and dementia.

In March 2024, Novo Nordisk’s Wegovy received FDA approval for reducing the risk of serious cardiovascular complications in adults with obesity and heart disease. This is based on the results shared from the company’s three-phase trial SELECT, which indicated that Wegovy reduced patients’ risk of major cardiovascular problems by about 20% during the five-year trial period.

Similarly, in 2019, the company started another clinical trial, FLOW, to determine the impact of GLP-1 agonists on kidney function. As per the interim results in October 2023, the trial displayed that Ozempic (Wegovy’s diabetes counterpart) reduced the risk of kidney disease progression and kidney and cardiovascular death in diabetes patients by 24%. Given its success, the company has halted the trial at the interim stage.

An initial study conducted on animals in March 2023 reportedly showed positive results for curbing addictive tendencies, such as drinking and smoking, with Ozempic. Currently, two trials are being undertaken to validate the use of GLP-1 agonists in humans to manage drug and alcohol addiction. Given the testimonies from current users of the drug, it is indicative that the drug has been helping users curb their addictions.

In addition to this, several researchers are also suggesting that GLP-1 could be used in the treatment of dementia and other cognitive disorders. This is based on the claim that GLP-1 agonists reduce the build-up of two proteins, amyloid, and tau, in the brain. These two proteins are known to be responsible for Alzheimer’s disease, which is the most common form of dementia. In February 2022, a new trial at the University of Oxford was initiated to test people with high levels of amyloid and tau and at risk of developing dementia to determine if the use of GLP-1 agonists would result in a reduction in tau accumulation and brain inflammation. The interim results from the study have not yet been disclosed.

High prices and limited coverage pose as speedbumps for obesity drug adoption

While these obesity drugs have exploded in popularity in recent times and are only expected to grow further as their case use increases, they do have certain shortcomings and challenges that are important to address.

These drugs are known to cause several side effects, such as nausea, diarrhea, vomiting, constipation, and ulcers. They can also lead to severe complications, such as pancreatitis, in some extreme cases. While most of the common side effects of the drugs are manageable and justifiable given the risk-benefit ratio, one of the key issues with the drugs is that they need to be taken in perpetuity to keep the weight off. In other words, once a patient stops taking the drugs, the weight comes back. Given that these drugs are priced at more than US$1,000 per month at the moment, taking them constantly becomes a considerable challenge for patients.

Moreover, considered as ‘vanity-use’, these drugs are currently not covered by most medical insurance policies, and thus, patients have to pay for them out-of-pocket. While several employers in the USA are considering including these drugs in their health plans, they are still debating their merit. Employers acknowledge the benefits of these drugs as they help employees who battle with obesity improve their health and, in turn, improve overall performance and employee satisfaction. However, high costs and long-term use act as definite barriers, which make both employers and insurers reluctant to cover these drugs.

Insurers are slowly warming up to the inclusion of GLP-1 drugs in their plans

In March 2024, leading insurance company Cigna stated that it would expand insurance coverage to include weight loss drugs but would limit how much health plans and employers spend on the drug each year. As per Cigna’s benefits management unit, Evernorth Health Services, spending increases for these weight loss and diabetes drugs would be limited to a maximum of 15% annually. The plan offers a financial guarantee and enables employers and health plans to have greater predictability and control over their GLP-1 spending by offering clients (employers) a guarantee that the cost of weight loss and diabetes drugs would not increase by more than 15% annually.

As a part of the effort to limit how much employers spend on GLP-1-based drugs annually, Evernorth has entered into an agreement with Novo Nordisk and Eli Lilly. However, the details of the agreement have not been disclosed.

While this is a good start, the drug would need better coverage by many other insurance players to reach a wider audience.

EOS Perspective

Given that about 12% of the global population and more than 40% of the American population grapple with obesity (as per WHO and 2022 statistics by the National Institute of Diabetes and Digestive and Kidney Diseases, USA, respectively), weight loss drug manufacturers Novo Nordisk and Eli Lilly are sitting on pharma goldmines. The weight loss drugs market, expected to reach US$100 billion by 2030, is poised as one of the most promising sectors for the pharma sector. Thus, it is no surprise that several leading players are investing heavily to join Novo Nordisk and Eli Lilly at the top, either through in-house R&D or through acquisitions.

However, developing these drugs proves to be challenging for drugmakers, as evidenced by the failures of several companies in creating their own versions. We can expect the sector to consolidate further as larger pharma companies look to acquire niche players with their trials being in advanced stages.

Moreover, in a bid to find their footing in this promising sector, pharma players are trying to develop advanced versions of the drug that have benefits beyond just weight loss and offer long-term benefits. This is also because, at the moment, these drugs are not approved by most insurance companies, which makes them extremely expensive for the wider population to afford. This, in turn, is withholding these drugs from becoming mainstream and is thereby preventing them from tapping into their true growth potential. That being said, Wegovy’s recent FDA approval for reducing cardiac complications in people with obesity and heart disease will likely tip the insurers’ coverage scales. Insurance companies are likely to cover the drug in the near future.

Since no other drug in the market offers proven cardiac benefits along with weight loss (including Eli Lilly’s), it is safe to say that Novo Nordisk is way ahead in the race and will dominate the market for the foreseeable future. Thus, to be able to compete in the market, it is not enough for drugmakers to develop obesity drugs offering just weight benefits. They would need to develop drugs that offer higher efficiency or additional therapeutic benefits along with weight loss and price them competitively.

PFA – A Potential Paradigm Shift in Atrial Fibrillation Ablation Landscape

Pulsed Field Ablation (PFA) is an emerging technology for treating atrial fibrillation (AFib), a form of irregular heartbeat affecting 40 million heart patients worldwide as of 2023. As the prevalence of AFib is increasing, all eyes are on this novel, minimally invasive technology that offers improved effectiveness, safety, and shorter procedure and recovery time compared to the existing thermal ablation procedures.

PFA applies short, high-voltage pulses of energy to cardiac tissue and is proven to be more precise and safe than the thermal ablation methods, which come with the risk of damaging collateral tissues.

A clinical trial conducted by Medtronic across North America, Europe, Australia, and Japan during 2022-2023 revealed that the efficacy performance of its PFA system PulseSelect stood at 66% in paroxysmal and 55% in persistent AFib patients against the pre-specified performance goals of >50% (paroxysmal) and >40% (persistent). Performance goals were set based on multiple studies conducted on thermal ablation procedures that evaluated efficacy based on the freedom from acute procedural failure and arrhythmia recurrence in one year.

Despite promising results, the first-generation PFA technology still needs improvement in targeting the tissue of interest, and players in the field are developing supportive systems such as mapping systems to improve performance.

PFA emerges as a better alternative to conventional ablation methods

PFA is viewed as the best evolution within the electrophysiology (EP) space (comprises ablation catheters, diagnostic catheters, laboratory devices, and access systems used to treat arrhythmia). The tissue-targeting approach of PFA overcomes the drawbacks of thermal ablation methods, such as extensive scarring and the risks of injuring nearby organs. Along with improving clinical outcomes, this transformative technology will significantly improve patient experience and reduce the cost of care by lowering procedure and recovery time.

Being safer than other ablation methods, PFA is set to become the preferred modality

Only about 2% of the eligible patients with AFib globally and 15% of the eligible patients in the USA were treated with ablation as of February 2023, according to a MedTech analyst at Bank of America. This is because thermal ablation comes with the risk of damaging nearby issues, which can lead to damage to the esophagus, phrenic nerve, and pulmonary veins.

A study published by the European Heart Rhythm Association in January 2024 comparing the outcomes of PFA and thermal ablations stated that the risk of injury from PFA was 3.4% compared to 5.5% in thermal ablation. PFA, being safer than thermal ablation, can be expected to reach many more eligible patients. After the launch of Boston Scientific’s Farapulse in Europe in January 2021, 38,000 AFib patients were treated there with the Farapulse PFA system during 2022-2023, compared to 2,000 patients Farapulse treated in 2021. Moreover, Boston Scientific predicts the global AFib ablation market will grow from US$5 billion in 2023 to US$11 billion in 2028, driven by the increase in the number of PFA procedures.

The growing adoption indicates that PFA has the potential to become the preferred method for treating AFib over the existing treatments, such as thermal catheter ablation and surgical ablation procedures.

Initial clinical trials indicate PFA results in better patient outcomes

With this new technology, patients will experience an improved quality of life with a significantly lower risk of complications and post-procedural discomfort.

This finds evidence in some of the studies performed by the industry. In January 2024, the European Heart Rhythm Association published a study comparing the performance of Boston Scientific’s Farapulse PFA system against thermal ablation systems in 1,572 patients across Europe. The study showed that 85% of patients who underwent PFA experienced overall freedom from AFib after one year, compared to 77% of patients who underwent thermal ablation procedures.

Reduced time of post-procedure care is PFA’s major advantage

With a duration of about 2 hours, the PFA procedure is shorter than thermal ablation, which takes 3-4 hours. More importantly, PFA requires a few hours of hospitalization post the procedure, while thermal ablation is typically associated with one day of hospitalization after the procedure.

Shorter hospital stays improve patient experience by minimizing stress and discomfort from longer hospitalization hours. They also enable faster scheduling, as hospitals can perform more procedures and minimize scheduling delays.

As PFA does not require in-patient admissions, PFA procedures will not be disrupted by hospital bed shortages. This is a considerable advantage, as many developed countries such as the USA and the UK lack adequate hospital bed capacity. As of 2021, there were 2.8 hospital beds per 1,000 population in the USA and 2.4 in the UK, below the WHO’s recommendation of 3.4 beds per 1,000 population.

Moreover, reducing the length of hospital stays yields significant cost savings for patients as well as the payers. Reducing a hospital stay by a day or several hours translates to savings that cannot be ignored. For instance, in the USA, the average cost of per-hour hospital observation is US$600 in 2024, as per the healthcare pricing transparency platform Turquoise Health. The average cost of per-day hospitalization was US$2,883 in 2021, as per a study by the Kaiser Family Foundation (Medicare patients are eligible for $1,632 reimbursement). In the UK, the average cost of per-hour hospital observation is US$100, and the cost of per-day hospitalization is US$442 as of 2022, according to the National Health Service.

Short learning curve and procedure time facilitate performing more procedures

A short learning curve equips more cardiologists and trainees with the skills required to perform and support the procedure faster. Cardiologists typically get comfortable with PFA procedures after 5-10 cases, which allows to expand the pool of specialists performing this treatment relatively quickly and easily. This, in turn, can significantly improve PFA accessibility.

As the shortage of physicians continues to worsen globally, particularly in the USA, which represented 50% of the ablation market in 2023, PFA can play a crucial role in facilitating an increase in the number of procedures performed at a hospital within the same timeframe. With an expected shortage of 120,000 cardiologists in the USA by 2030, according to a 2021 report by the Association of American Medical Colleges, performing quicker procedures can help to partially offset the lack of specialists. Since PFA takes 30-50% less time than conventional ablation methods, it has the potential to significantly increase the number of procedures performed.

MedTech companies grow their ablation market share by offering PFA devices

With increased health screening efforts that detect more patients with arrhythmias, the number of cardiac ablation procedures performed globally doubled between 2013 and 2023 to reach about 650,000 procedures in 2023.

Boston Scientific expects the global AFib ablation market to more than double to US$11 billion during 2023-2028, with PFA predicted to grow to more than 80% of procedures (from under 5% in 2023). PFA technology is expected to be adopted quickly. As seen in Europe, PFA devices were launched in 2021, and already about 12% of the ablation procedures in the region in 2023 were done using PFA technology.

J&J, Medtronic, and Boston Scientific take the lead in the PFA field

Eyeing the potential of this emerging market, MedTech giants such as Johnson&Johnson (J&J), Medtronic, and Boston Scientific (accounting for 55%, 10%, and 5% share of the global thermal ablation market in 2023, respectively) have entered the market with their newly developed PFA devices. Being early entrants, these companies have the potential to expand their market shares in the cardiac ablation market by grabbing shares from thermal ablation procedures.

Boston Scientific was the first company to commercialize PFA devices with the launch of the Farapulse PFA system in Europe in January 2021. Boston Scientific enjoyed a two-year monopoly in the European market until Medtronic launched an integrated mapping and PFA system called Affera in March 2023. Later, the company launched another PFA system, PulseSelect, in December 2023. In February 2024, J&J’s Varipulse PFA system also received approval in Europe.

In the USA, Medtronic was the first company to receive FDA approval for its PFA system PulseSelect in December 2023, followed by Boston Scientific in January 2024. Medtronic also received FDA approval for Affera in March 2024.

J&J is the only company with a presence in Asia, as the company received approval for its PFA system in Japan in January 2024. Abbott is currently conducting clinical trials for its PFA system Volt in Australia and expects to start clinical trials in the USA this year.

The companies work to enhance and improve their systems. For instance, Medtronic’s integrated mapping and PFA system Affera offers enhanced procedure performance supported by real-time mapping. The integrated system includes an ablation catheter Sphere-9 and mapping software to facilitate real-time mapping. Sphere-9 catheter can perform high-density mapping and ablation simultaneously to allow cardiologists to deliver wide-area focal ablation lesions quickly. Affera can also work with the PulseSelect PFA system to provide real-time mapping. Similarly, J&J has a 3D mapping system called Carto 3 (in the market since 2009), which integrates well with its PFA system and generates real-time 3D mapping that aids in better cell targeting. Boston Scientific has not developed an exclusive mapping system for its PFA system, however, the company claims that any catheter mapping system will work well with Farapulse.

Comparing the PFA systems’ performance in the clinical trials, all systems, including Boston Scientific’s Farapulse, Medtronic’s PulseSelect, Medtronic’s Affera, and J&J’s Varipulse proved to be effective in over 70% of patients in terms of freedom from arrhythmia recurrence in one year.

Currently, PFA devices are only available in the USA, Europe, and Japan, with Boston Scientific dominating in Europe. Boston Scientific has witnessed high adoption rates in Europe so far, and the company has been able to serve 40,000 patients in three years since its entry into the European market in 2021. The company expects an overall organic sales growth of 8-10% during 2024-2026, driven by its PFA devices. Medtronic and J&J have just launched their PFA systems in the USA and Europe, and how these companies perform has yet to be seen. Analysts from BTIG financial services firm predict that Medtronic’s PulseSelect will secure 9% and Boston Scientific’s Farapulse will secure 14% of the cardiac ablation market (which comprises PFA and two other forms of thermal ablation procedures – radiofrequency and cryoablation) in the USA by 2025.

With competent technologies, the market is expected to witness stiff competition from these companies. Analysts from BTIG financial services firm predict that by 2027, PFA will grab 48% of the US cardiac ablation market, while the radiofrequency ablation market will have a 42% share and cryoablation a 10% share. The expected PFA’s 48% market share is likely to be split amongst the leading PFA systems – Boston Scientific’s Farapulse, J&J’s Varipulse, Medtronic’s PulseSelect, and Medtronic’s Affera, at 16%, 13%, 10%,7%, respectively, followed by others with 2% share.

While these companies have already entered the PFA space, Abbott’s wait-and-see approach to PFA may backfire on its performance in the EP market. The company aims to commercialize its PFA system Volt in the USA by 2027 or 2028. However, PFA’s fast adoption threatens Abbott’s US$1.9 billion EP business and its 15% global thermal ablation market share (as of 2023). Growing PFA adoption could also threaten Abbott’s diagnostic catheter and mapping systems, as healthcare providers using PFA systems would prefer buying mapping systems linked to PFA.

New entrants to drive innovation and further improve PFA technology

Apart from the large players, there are a few smaller players, such as Canada-based Kardium, US-based Adagio Medical, and US-based Pulse Biosciences, that are developing PFA systems. These companies are investing in improving the PFA using nanotechnology and supportive systems such as 3D mapping systems. For instance, Pulse Biosciences developed Nanosecond PFA (nsPFA) technology that uses superfast nanosecond pulses of electrical energy that can regulate cell death, which spares adjacent noncellular tissue. The company expects FDA approval for this system in 2024.

EOS Perspective

Over the years, MedTech companies have been actively pursuing the development of minimally invasive procedures that have shorter recovery periods, offer improved patient outcomes and reduced post-procedure discomfort. As the limitations of the existing ablation methods became apparent, PFA poses a vast growth potential, as it is a safer, more convenient, and more effective alternative.

On the other hand, the pulsed-field waveform is significantly more complex than the energy modalities that preceded it, with numerous variables determining the dose targeted at the tissues and the quality of the resulting lesion. While a variety of PFA systems have demonstrated effective ablation procedures, these systems have yet to advance in overcoming all limitations of targeting the tissue of interest and rare but potentially serious complications.

In the coming years, we can expect companies to develop multiple catheter configurations that allow cardiologists to configure the energy delivery to achieve the desired energy dose and lesions. This includes the development of multi-configurable ablation catheters that can shift shapes to create circular, linear, or focal ablation lesions without performing catheter exchanges.

As the technology advances, we can expect PFA to dominate the AFib ablation market and democratize AFib ablation procedures by improving accessibility to all eligible patients.

Digital Therapeutics: The Future of Healthcare?

Although the COVID-19 pandemic seems to be done with its rampage, many people still opt to access all kinds of services, including healthcare, from the comfort of their homes. As this trend is expected to continue, the global digital therapeutics market, with its projected growth at a 20% CAGR from 2022 to 2035, is one important sector healthcare firms should focus on right now.

Digital therapeutics (DTx) are digital health interventions or software applications that are clinically validated and designed to treat or manage medical conditions. They can be used alone or in conjunction with traditional medical treatments.

The Digital Therapeutics Alliance categorizes DTx products into three types: disease treatment, disease management, and health improvement.

Examples of DTx include a solution to manage chronic musculoskeletal pain developed by Kaia Health, a biotechnology company in New York. This motion analysis tool assesses and guides patients’ progress during physical therapy and tailors treatment to individual requirements.

Similarly, Clickotine from Click Therapeutics, a company also based in New York, uses AI to help people with nicotine addiction. This solution offers a personalized plan fully integrated with eight weeks of nicotine replacement therapy, including options such as gum, patches, or lozenges. It tracks critical aspects such as daily cigarette counts, craving triggers, craving times, etc. A trial study conducted by the company in 2016 claimed that 45% of Clickotine users were able to quit smoking.

Adoption of DTx is taking off amid increased investments

The commercial development of DTx started around 2015 and, since then, has grown into a global market of considerable size. The total value of global DTx start-ups was estimated at a whopping US$31 billion in 2022, according to a 2022 report published by Dealroom, an Amsterdam-based firm offering data and insights about start-ups and tech ecosystems, in partnership with MTIP (a Swiss-based private equity firm), Inkef (an Amsterdam-based early-stage venture investment firm), and Speedinvest (an Austrian early-stage investor).

The number of people using DTx solutions is expected to increase over the next few years, according to a 2022 report by Juniper Research, a UK-based research firm. The study found that there were 7 million DTx users in the USA in 2020, a number expected to rise to around 40 million in 2026.

This increase can be attributed to the fact that DTx solutions are highly accessible and distributable due to an increase in the use of smartphones. A 2021 report published by Pew Research Center, a US-based think tank, found that 87% of Americans owned a smartphone in 2021, compared to 35% in 2011. With this, more people will be able to access medical care without having to spend more on hospital visits.

DTx applications have also been attracting numerous investors owing to the applications’ cost-effectiveness, ease of distribution, and better accessibility. According to the same 2022 report published by Dealroom, global venture capital funding in DTx witnessed a fourfold increase in 2022 compared to 2017.

All these studies reveal that, despite certain challenges, the DTx applications hold the promise of developing into a practical and affordable means of treating illnesses and conditions that impact large numbers of people.

Regulatory pitfalls present a major roadblock to DTx adoption

One main challenge DTx companies face is the regulatory environment. All DTx products must comply with the regulations of regional agencies such as the FDA, HIPAA, HITECH, etc.

Many US firms initially faced regulatory obstacles and payer resistance around product reimbursement. Before 2017, the US FDA classified DTx solutions as a SaMD (Software as a Medical Device) and, therefore, made them subject to risk assessment (low, medium, or high). Due to this, DTx solutions needed premarket approval and rigorous clinical trial results to get approval.

This has improved with the introduction of the Digital Health Innovation Action Plan by the FDA in 2017. According to the new plan, the FDA will first consider the company producing the solution. If the producer has demonstrated quality and excellence, it can market lower-risk devices with a streamlined premarket review. Post-market surveillance and data collection are also done to evaluate product efficiency.

Similarly, in the EU, DTx is controlled by national competent authorities and governed by the European Regulation on Medical Devices 2017/745 (MDR). However, no specific framework indicates the evidence required for assessing the performance or quality of DTx solutions or their production standards. This means that the member states may interpret the dossier requirements differently, leading to a fractured regulatory environment.

The COVID-19 pandemic has provided companies with some regulatory flexibility, leading to an increase in venture capital funding. In 2020, the federal government in the USA issued a new rule allowing healthcare practitioners to treat patients across state lines, including the use of digital medicine. This can increase access to healthcare, especially in rural areas, and physicians will be able to offer timely care to their patients traveling in a different state.

The FDA has also loosened regulations during COVID-19, particularly for mental health products, with the Digital Health Innovation Action Plan. This was to ensure that patients received timely care even from their homes while reducing the burden on hospitals. It waived certain regulatory obligations, such as the need to file a 510(k) premarket notification during the COVID-19 pandemic. The 510(k) is a submission indicating that a new medical device is similar to something already approved by the FDA (a predicate device) to ensure safety and efficiency. However, finding suitable comparables can be highly challenging in the case of DTx, which is dynamically evolving. This can result in misunderstandings or overlooking of critical aspects of these solutions, leading to uncertainty and delays in the approval process. The waiver of this regulation offers DTx companies some relief in the future.

Digital Therapeutics – The Future of Healthcare by EOS Intelligence

Patient health literacy is a hurdle in the adoption of DTx solutions

A survey by the National Assessment of Adult Literacy (NAAL) in 2003 has shown that only 12% of Americans possess proficient health literacy skills, making them able to find and understand information related to their health. This lack of awareness among patients can also impede the ease of applying DTx products.

Patient experience is also crucial for the acceleration of DTx adoption. Older patients unfamiliar with using technological gadgets can find it difficult to adopt DTx solutions. However, a 2022 AMA survey has shown that 90% of people over the age of 50 in the USA recognize some benefit from digital health tools.

Similarly, a survey conducted by the Pew Research Center in 2021 indicated an increase in the use of smartphones and the internet among older people in the USA, driven by the pandemic. Older adults are using technological applications for activities such as entertainment, banking, shopping, etc., even after the pandemic, a 2021 survey by AARP Research, a US-based NPO, shows. This indicates that there is scope for an increase in adoption.

Many companies are now trying to increase patient involvement by using gamification, aiming at patient groups for whom DTx use is likely to be more challenging (e.g., older population, children). DTx developers include game-like elements or mechanics into a DTx solution, such as tasks, rewards, badges, points, and leaderboards. An example is US-based Akili Interactive’s EndeavorRx, a prescription DTx aimed at enhancing attention function in children with ADHD aged 8 to 12. It uses an interactive mobile video game to assist children in improving their attention skills and adjusting to their performance levels. The game’s sensory stimuli and motor challenges also help kids multitask and tune out distractions.

Payer reluctance affects many DTx products

Although the number of DTX products on the market increases, payers’ reluctance to cover their costs to the patient can also slow down adoption. The coverage of DTx solutions is limited, even when they are FDA-approved. Only 25% of payers are currently willing to cover prescription DTx solutions, according to a 2022 survey by MMIT, a Pennsylvania-based market data provider, which involved 16 payers.

Akili Interactive’s EndeavorRx is one such solution facing insurance coverage issues. Elevance Health (previously Anthem) denied coverage for EndeavorRx, deeming it medically unnecessary, while Aetna, another insurance provider, considers it experimental and investigational.

A study released by Health Affairs, a health policy research journal, in November 2023 has shown that only two of the twenty FDA-approved prescription DTx solutions on the market have undergone rigorous evidence-based evaluation. This means that no authoritative results indicating the benefits of these solutions for various population demographics are available, making many payers skeptical of their medical claims.

DTx offers solutions for managing multiple conditions

Over the past few years, several prominent players have emerged in the DTx landscape. Around 59% of the DTx market is concentrated in the North American region and 28% in Europe.

Top players, such as Akili Interactive and Big Health, both US-based firms, focus on offering products for managing mental health illnesses, mostly management of anxiety, depression, and stress, according to a report published in 2023 (based on data until September 2022) by Roots Analysis, an India-based pharma/biotech market research firm. With about 970 million people suffering from mental health conditions globally (according to the WHO), the potential user pool is enormous, offering growth opportunities for DTx solutions developed to address mental illnesses and, over time, driving the growth of the DTx market as a whole.

Many top companies also focus on solutions offering pain management and treatment for chronic conditions such as diabetes, obstructive pulmonary disease, and musculoskeletal disorders. An example is US-based Omada’s pain management solution, Omada MSK. This application guides patients through various customized exercises and records their movements, which are then assessed by a licensed physical therapist (PT), who can make recommendations for improvement. It also has a tool that utilizes computer vision technology to help PTs virtually assess a patient’s movement and range of motion, allowing them to make necessary changes in the therapy.

Similarly, several DTx solutions on the market now focus specifically on diabetes, which affects around 537 million adults globally. Some top companies focus on the previously unmet needs of conventional methods, such as weight management or preventing prediabetes, to help with overall diabetes treatment. US-based Omada’s solution, Omada Prediabetes, comes with a weight scale pre-connected to the app, and the weight is added to the app as soon as the patient steps on the scale. A dedicated health coach assesses the patient’s weight, creates a customized plan, and monitors the patient’s progress. In other similar DTx solutions for diabetes, an app can also give insulin dose recommendations based on the patient’s blood glucose levels.

DTx can serve in a range of other conditions, including major depressive disorder, autism spectrum disorder, and multiple sclerosis, to name a few.

The DTx landscape is rife with development

The DTx business landscape has recently seen many developments, from acquisitions to product launches. One of them was Big Health’s acquisition of Limbix, a California-based DTx firm, in July 2023 to bolster its portfolio, including SparkRx, a treatment for adolescents dealing with depression and anxiety. Similarly, in June 2023, Kaia Health launched Angela, a HIPAA-compliant, AI-powered voice-based digital care assistant, to serve as a companion and guide, enhancing the physical therapy experience for patients.

In another development, BehaVR, a DTx company headquartered in Kentucky, and Fern Health, a digital chronic pain management program, merged their companies in November 2023 to create a novel pain management DTx solution that addresses both pain and fear caused by chronic diseases. With this merger, they launched RealizedCare, an app designed to offer a comprehensive solution that collaborates with health plans, employers, and value-based providers to treat a range of behavioral and mental health conditions. This solution provides clinicians with immersive programs specifically designed for in-clinic use. It is initially focusing on chronic pain.

Bankruptcy of Pear and lessons for the industry

However, the most shocking development in the DTx market was the bankruptcy of Pear Therapeutics in 2023. The remains of this once-prominent company were purchased by four other companies for a total of US$6.05 million at an auction. Pear was a big name in the industry since its inception in 2013. It introduced numerous products such as reSET, reSET-O, and Somryst for treating substance use disorder, opioid use disorder, and chronic insomnia, respectively. It was also the first company to receive FDA approval for a mobile app aimed at treating substance use disorders.

Though the company announced layoffs of nearly 20% of its workforce in November 2022, its management expressed optimism about the company’s growth and reduced operating expenses in the third quarter. But in April 2023, the company filed for bankruptcy.

The demise of Pear has opened the eyes of industry experts to the challenges faced by DTx players. Certain issues were unique to Pear itself, such as the comparatively higher prices of its products and the focus on treating challenging conditions such as substance use disorders. However, the bankruptcy of Pear also brings attention to the obstacles that can be faced by any other DTx company. One crucial roadblock is that physicians and payers still approach these products with caution. Additionally, achieving profitability for DTx might be challenging for all types of players, particularly for small start-ups lacking substantial market influence. The bankruptcy of Pear and the challenges it faced can be used by budding DTx companies as a road map as they navigate this complex sector.

EOS Perspective

DTx is all set to revolutionize the medical industry, with a 2020 McKinsey report suggesting it could potentially alleviate the global disease burden by up to 10% by 2040. Given the impact of emerging treatments on stakeholders, pharmaceutical and healthcare companies should consider expanding their portfolio to include DTx solutions.

With telehealth companies seeing good growth in the pandemic and post-pandemic years, an increase in investment can be expected as they are uniquely placed to support prescription DTx. With the growth of the digital health industry, prominent telehealth providers may also choose to acquire DTx businesses or create their own in-house DTx solutions.

 COVID-19 Outbreak Boosts the Use of Telehealth Services

An increase in industry M&A activities can be expected in the next few years, with growing incidences of chronic illnesses, improved technology penetration across all age groups, and a maturing market. Big names such as Bayer, Novartis, and Sanofi are also entering into partnerships with DTx companies, indicating a bright future for the sector.

Mental health and behavioral therapy are great fields to branch out for companies starting in the DTx landscape, especially in this post-pandemic era. Demand for such services is likely to be sustained, considering the National Institute of Mental Health Disorders estimates that one in four adults in the USA suffers from a diagnosable mental illness, with many suffering from multiple conditions.

Similarly, diseases such as diabetes, cancer, heart, and respiratory ailments are on the rise. Healthcare companies can effectively address these medical areas through the use of DTx applications, providing personalized care for patients. This approach has the potential to manage not only chronic conditions such as diabetes but also terminal illnesses such as cancer.

Many DTx players will likely focus on areas with unmet needs, including pediatrics and metabolic disorders. With seven DTx-based diabetic management solutions already receiving 510(k) clearance as of December 2022, it can be expected that more products addressing the treatment gaps might flood the market.

The DTx industry is gradually maturing and has been receiving significant investments in recent years (US$8 billion in 2022). While experts view it as a profitable market, hesitation remains, particularly following the bankruptcy of Pear Therapeutics.

Nevertheless, due to the COVID-19 pandemic and subsequent lockdown measures, technology adoption among older adults has increased significantly. Hence, strategic investments in DTx by pharmaceutical and healthcare companies, taking into account market conditions, can expect to establish a stronger presence in this industry in the future.

Soaring Healthcare Costs in the USA: Is Greed Winning Over Welfare?

Americans have been struggling with access to affordable healthcare for years, with thousands of stories of an unexpected illness driving a patient to bankruptcy. Meanwhile, the USA spends much more than European nations on healthcare but covers the smallest percentage of the healthcare costs. Wasteful spending, excessive administrative costs, no limit to medicines prices, lack of a single unified interface system, and passive attitude by the government are all building blocks of a wall separating Americans from the quality and affordable healthcare system expected from any developed country.

According to a 2020 article published by Harvard, the annual cost of healthcare in the USA was around US$3.5 trillion, of which around 33% is believed to have been squandered. Simultaneously, healthcare costs are soaring, contributing significantly to several issues around the delivery and affordability of healthcare in the USA. The same Harvard article revealed that about 40-44% of Americans decided to omit or postpone medical treatment, tests, or care owing to their high costs. Although the USA has the highest national healthcare expenditure, the country registers one of the lowest life expectancies among the developed economies. Additionally, around 10% of the population does not have health insurance.

This problem is so deep-rooted and widespread that the issue of healthcare costs was referred to as the “tapeworm of American economic competitiveness” by investor Warren Buffet. Almost 67% of the US population wishes the federal government to regulate healthcare prices in the country. Yet, despite it being such a grave problem, the US government does not seem to be taking any (visibly) constructive measures to resolve it. While significant political aspects are certainly at play, a deep dive into the cost drivers of the US healthcare system might shed some light on the complexity of this issue.

Soaring Healthcare Costs in the USA – Is Greed Winning Over Welfare by EOS Intelligence

Healthcare administrative costs hold the lion’s share of total healthcare expenditure

One of the major components of healthcare costs in the USA is the annual cost of healthcare administration at US$1,055 per capita, according to a 2021 estimation by the Peterson Foundation. The US spending on healthcare administrative purposes is by far the highest globally. Compared with Germany, the second-highest spender on healthcare administration at US$306 per capita, the stark difference of US$749 per capita speaks volumes about the current situation in the USA. The country also registers the world’s highest share of administrative costs in total healthcare costs, at around 15-30% annually. Wasteful administrative spending is estimated to contribute about half of that share (7.5% to 15% of the country’s total healthcare spending), translating to anywhere from US$285 billion to US$570 billion in 2019.

The USA spent around US$950 billion in 2019 on healthcare administration, which translates to 25% of the national healthcare expenditure (NHE) that year. A significant part of the excessive administrative expenditure is billing and insurance-related costs (BIR), including overhead costs for medical billing and services such as claim submission, claim reconciliation, and payment processing. Profits made by the insurance companies account for the highest share of BIR costs. Healthcare providers also get part of these administrative costs for note-taking and record-keeping during the medical billing process. According to an article published by Harvard in 2020, there are occupations in US healthcare that do not exist elsewhere, such as medical-record coding to claim-submission specialists. Further, the article claims that in other countries, such as Germany and Switzerland, where multiple payers and private providers exist, healthcare administration costs less than 50% of the USA equivalent.

As per 2019 McKinsey research, the USA could decrease healthcare administrative expenditure by 30% through automation and streamlining of the BIR processes. Claims processing software enables automation of BIR processes, however, only 15% of US hospitals employ such software, as per Definitive Healthcare tech data.

Healthcare services costs, including physicians’ salaries, empty patients’ pockets

A 2018 JAMA study revealed that physician salaries in the USA were higher than in other developed countries. A survey by Medscape in 2021 revealed that physicians earned the most in the USA compared to other developed countries. On average, the annual income of physicians in the USA was US$316,000, followed by Germany (US$183,000) and the UK (US$138,000).

As per 2019 Commonwealth Fund research, Americans are much less likely to consult a doctor in case of a health issue, at half the rate compared to other developed countries. This can be attributed to the fact that the cost of healthcare services is considerably higher in the USA vis-à-vis other developed nations. According to a 2017 report, the average cost of a coronary artery bypass graft (CABG) surgery in the USA was US$78,100, whereas the same procedure cost only US$11,700 in the Netherlands. While the procedure cost is already far lower, in the Netherlands, patients will likely have the procedure cost fully covered by insurance without any co-payment. The USA also reported higher costs for outpatient procedures such as MRI scans and colonoscopies compared with other developed countries.

Skyrocketing prescription drug prices further inflate healthcare costs

As per OECD, in 2019, the average spending on prescription drugs by an American was about US$1,126 per capita, which was over double that in other developed nations. As per CMS, prescription drug spending in the USA by the federal government is expected to grow by 6.1% through 2027.

The growth in prescription drug spending could be attributed to increased focus on specialty pharmaceuticals and precision medicine. Specialty medicines are experimental therapies for treating cancers, autoimmune diseases, or chronic conditions. Some specialty medicines employ genetic data to provide highly targeted, personalized therapy. Owing to the complex nature of these drugs, they are generally expensive to develop and distribute.

For instance, a novel specialty drug called Hemgenix to treat hemophilia B is the most expensive drug ever approved by the FDA. The price of a single infusion of this gene therapy is around US$3.5 million. No healthcare providers have submitted a claim for Hemgenix so far in 2023.

Apart from specialty medicines, pricing strategies for drugs in general play a significant role in soaring healthcare costs in the USA. Drug producers set a list price based on their product’s estimated value, and the price list can be increased by the producers as they see fit. In the USA, there are few regulations to curb producers from increasing drug prices in this way.

Chronic diseases add fuel to the fire of escalating healthcare costs

As per the CDC, six out of ten adults in the USA have a chronic disease or condition. The most common chronic diseases or conditions in the USA include heart disease, stroke, cancer, diabetes, chronic kidney disease, and chronic obstructive pulmonary disease (COPD). Furthermore, according to 2022 research published in the National Library of Medicine, of the population 50 years and older, the number with at least one chronic disease is estimated to increase by 99.5% from 71.522 million in 2020 to 142.66 million by 2050.

There is a robust correlation between the prevalence of chronic diseases and rising healthcare costs. As per a report from the American Action Forum, the USA spends about US$3.7 trillion annually for the treatment of chronic health diseases and the consequent loss of economic productivity. Routine office visits, prescriptions, outpatient treatments, or emergency care account for most of this healthcare spending in the USA.

Expanding geriatric population contributes to rising healthcare costs

According to the US Census Bureau, 21% of the US population is expected to be 65 years or older by 2030. The growing aging population is expected to drive healthcare costs in the USA in two ways: through Medicare enrollment growth and the increase in the prevalence of more complex and chronic conditions. Medicare had over 65 million beneficiaries as of March 2023, a number that is expected to increase by 2030 dramatically. This enrollment growth will impact NHE since Medicare is a publicly funded program. As per the CMS, in 2020, the USA spent US$900.8 billion on Medicare, and the CMS expects that Medicare spending will surge by 7.6% annually through 2028.

The elderly population is vulnerable to chronic conditions such as hypertension, high cholesterol, diabetes, coronary heart disease, and Alzheimer’s disease, among others. According to the National Council on Aging, 80% of older Americans have a chronic condition, and 77% of older adults have two or more chronic conditions. These chronic conditions will require ongoing treatment or long-term care at a nursing home or assisted living facility. These outcomes will account for increasing healthcare costs and overall national healthcare expenditure in the USA.

Greed over welfare

Corporate avarice is another factor said to be responsible for the rising healthcare costs in the USA. Insulin list price in the USA is 10 times higher than that in Canada. Not only pharma companies but also renowned hospitals charge more for the same service compared with less renowned hospitals. This applies to various services, from complex surgeries to simple X-rays.

Price regulation is the only solution to this problem that could be implemented with enough political will. The US state of Maryland has introduced this regulation for hospital services, while most European countries have regulated the prices of pharmaceuticals. However, implementing price regulation would mean that the compensation of the top management executives or the CXOs would decline, or the budget for R&D would reduce. This causes much resistance among top management executives to arrive at a constructive decision of choosing between self or service. However, the fact that patients delay treatment because of rising prices speaks strongly in favor of introducing at least some level of price regulation.

EOS Perspective

Standardization is one of the key ways to decrease administrative costs. Just for comparison purposes, checking out of a grocery store is easy because all products possess bar codes, and all credit card machines are the same or uniform. Similarly, mobile banking and inter-banking are straightforward since the Federal Reserve has set standards for how banks should interface with each other.

However, the American healthcare system has been immune to such a standardization. Every health insurer needs a different bar-code-equivalent and payment-systems submission. In addition, it is tough to send electronic medical records (EMRs) from one hospital to another because there is no mandate by the federal government for them to be in compatible formats. Additionally, this lack of standardization benefits many healthcare providers, as they strive to avoid the interchange of EMRs to prevent patients from switching doctors.

Standardization is possible only when prominent stakeholders are involved in it, agree to it, and decide they need it. The largest stakeholder in the US healthcare system is the federal government. Buying capacity and administrative control to compel payers and providers to adopt billing and interface rules to standardize the process lies within the federal government’s responsibilities.

Similarly, a price cap regulation needs to be brought about in the pharmaceutical sector. Price regulation is the only way to lower the prices of prescription drugs. Apart from this, the federal government needs to implement price cap regulation in healthcare services such as X-rays, MRIs, CT scans, etc.

It is the government that should introduce regulations that put caps on drugs and services prices, at least in certain product and service groups. It is the government that should establish the infrastructure to materialize standardization and introduce a deadline by which all interactions must be standardized.

However, to date, the federal government only considers providing insurance – particularly Medicare and Medicaid – to people as its role rather than looking out for the entire healthcare system as a unit. This mentality needs to change if healthcare costs are to be brought down.

Bridging the Gap between MDx Testing and Point-of-care

The COVID-19 pandemic brought innovation and investment to the in vitro diagnostics (IVD) market, opening new pathways to simplify and expand testing. The previously complicated and time-consuming molecular testing gradually started moving towards rapid testing, changing how we manage healthcare. The growing popularity of rapid testing gave way to self-sampling and at-home sampling, which is set to bring molecular testing closer to patients. Another noticeable transformation the industry witnessed post-pandemic was the rise of molecular testing at point-of-care (POC), which is set to disrupt the way clinicians deliver accurate diagnoses in record time.

The latest generation of IVD devices is focused on providing quick diagnosis and being cost-effective. This has led to IVD companies focusing on developing simpler and less invasive sample collection methods, such as self-sampling tests.

IVD innovation is also transforming molecular testing to make healthcare more accessible. To a certain extent, dependence on laboratories is gradually decreasing with molecular testing available at POC. A key development in this area is the use of multiplex assay, which allows to test for multiple pathogens simultaneously, allowing for early diagnosis.

Molecular testing moving near-patient

After using antigen tests during COVID-19, demand for molecular testing for a variety of diseases at POC has risen drastically. In 2023, the industry faced an acute shortage of skilled laboratory staff, further increasing the need for molecular testing to move near-patient. This has resulted in physicians and patients preferring molecular tests at POC (MPOC). Some prominent industry players, such as Cepheid, Abbott, and BioFire, offer CLIA-waived PCR instruments and multiplex assay tests for the POC setting. A CLIA-waived certification allows tests to be performed at a doctor’s office by a non-technician instead of other more complex MDx tests requiring specialized technicians.

Moving these multiplex molecular tests near-patient is revamping the IVD landscape, positively impacting both the patients and payers. Early diagnosis with POC diagnostics empowers physicians with evidence-based decision-making at an early stage. Moreover, with multiplex assays increasingly being used for MPOC and delivering results within 10-25 minutes (in the case of respiratory assays), the wait time for patients to receive the correct diagnosis has reduced substantially. This results in clinicians being able to start with proper treatment on the patient’s first visit, thus reducing the total number of patient visits. Consequently, physicians are also able to accommodate a higher number of patients.

In fact, MPOC could become a critical element of the value-based care model in the USA. The value-based program incentivizes healthcare providers/physicians to provide quality healthcare. With MPOC offering quicker turnaround time and lower testing costs, physicians/payers will likely be better incentivized and motivated to deliver high-quality services.

Growing demand for self-sampling/at-home sampling

The pandemic raised public awareness regarding the use of self-sampling kits and increased demand for them. Further, the FDA granted Emergency Use Authorization to multiple assays during the pandemic to quickly onboard self-test kits and penetrate the US households with this novel testing method.

Driven by the convenience, cost-effectiveness, and accessibility offered by self-sampling kits, they are becoming increasingly popular, particularly amongst the aging population that needs tools and technologies to manage health at home. It is also proving to be a sustainable testing method, as it can be used for preventative screening as well as allows for discretion for patients who may not prefer to get tested in a laboratory or by a physician, particularly in case of sexually transmitted infections (STIs).

Additionally, unlike OTC tests, molecular diagnostic tests allow for better accuracy in results and are recognized by the FDA for clinical diagnosis use. This has given confidence to healthcare providers to advocate self-sampling, as they stand to benefit from bringing care to patients’ homes, eventually reducing healthcare expenses. In a value-based setting, at-home testing proves to particularly benefit physicians who are able to eliminate unnecessary patient visits.

For the prominent industry players, at-home testing represents a key opportunity area to grow in the niche direct-to-consumer testing segment. Companies are also using these tests as an opportunity to target the rural population who do not have easy access to laboratories. Besides infectious and respiratory diseases, companies are now trying to foray into other treatment areas, such as human papillomavirus (HPV). Self-sample collection for HPV has begun in Europe with BD’s Onclarity HPV assay.

EOS Perspective

Establishing a strong foothold in both self-sampling and MPOC segments is seen as a sizeable business opportunity for stakeholders of the IVD market. In the near term, it is likely for the IVD players to continue launching new assays and technologies to expand offerings.

For self-sampling, MDx players have been focusing on infectious diseases, and there still is a vast untapped market for self-sampling at home, specifically when testing for STIs. In November 2023, LetsGetChecked became the first company to secure FDA approval for chlamydia and gonorrhea at-home sample collection. This has opened doors for other players to enter this niche market, and they are likely to jump on the bandwagon by seeking FDA approvals for their STIs self-sampling kits. Major players, such as Hologic, are already gathering data to launch a self-collection device for STIs. Hologic’s Aptima Swab for STIs multi-testing is approved in the EU, and the company is now conducting trials to get approval in the USA.

In the near term, a noticeable trend in the MPOC segment is expected to be the focus of MDx players on developing multiplex assays that follow the ‘one-size-fits-all’ approach. There is a growing demand from physicians for multiplex assays that allow them to test for multiple viruses and deliver results in under four hours. Companies have already started to take matters into their own hands by focusing their R&D efforts on developing panels and preparing them for FDA approval and CLIA waiver. Becton Dickinson announced the launch of its first molecular diagnostics POC instrument, BD Elience, by 2025. The device is expected to allow panel testing for respiratory and sexually transmitted diseases.

Although the self-sampling and MPOC segments present many opportunities for the IVD stakeholders, some roadblocks may hinder their development and adoption. For instance, multiplex assay reimbursement schemes may hamper their widespread adoption in the POC setting. Per the latest guidelines, reimbursement schemes for multiplex assays are less favorable than those for singleplex assays. Furthermore, at present, there are no reimbursement schemes in place to reimburse for self-sampling at home, so patients are required to pay out-of-pocket.

Several players face a crucial challenge for at-home collection: proving to the FDA that the self-sample collected is not contaminated or poorly taken. FDA requirements for approval of these tests are very stringent and demand that companies prove the adequacy of the sample collected by patients to match that of laboratory collection.

Despite these challenges, self-sampling and MPOC present untapped opportunities for many IVD players seeking to expand their capabilities and offerings to position themselves better in the MDx market.
