Coya Therapeutics Announces Publication of GLP-1/LD IL-2 Combination Biologic (COYA 303) Demonstrating Synergistic Enhancement of Regulatory T Cell Function and Protection Against Treg Apoptosis (Cell Death)
HOUSTON--(BUSINESS WIRE)--Apr 21, 2025--
Coya Therapeutics, Inc. (NASDAQ: COYA) ('Coya' or the 'Company'), a clinical-stage biotechnology company developing biologics intended to enhance regulatory T cell (Treg) function, today announced publication of the results of a study designed to evaluate the effects of COYA 303 (LD IL-2 and GLP-1RA), Coya's investigational biologic combination to suppress pro-inflammatory myeloid cells, enhance Treg suppressive function, and modulate T cell proliferation, in an in vitro system of human immune cells obtained from healthy donors. The research was conducted at the Houston Methodist Research Institute and was led by Dr. Aaron Thome and Dr. Stan Appel. The research article has been published in the Journal NeuroImmune Pharmacology and Therapeutics and can be accessed here.
Dr. Arun Swaminathan, Coya's Chief Executive Officer, stated, 'We believe COYA 303 could offer a differentiated and synergistic approach to addressing multiple conditions, including in neurodegenerative conditions such as Alzheimer's Disease, in which GLP-1 RAs have recently shown promise. We believe the potential of this proprietary combination could lead to value-creating opportunities and may open up a new avenue of research within the GLP-1RA drug class.'
LD IL-2 preferentially binds the IL-2 receptor alpha, which is predominantly expressed on Tregs to enhance their anti-inflammatory suppressive function. Treg dysfunction has been well documented in several autoimmune and neurodegenerative diseases characterized by persistent inflammation. GLP-1RAs also exhibit several immune-modulating effects, with myeloid cells and regulatory subsets, such as Tregs, expressing a large concentration of GLP-1 receptors. Although increased Treg numbers and enhanced suppressive function are seen with LD IL-2 treatment, their longevity and suppressive function can be limited by the effects of pronounced and sustained inflammatory environments. Therefore, a combination therapy approach that dampens the inflammatory microenvironment while enhancing Treg survival and function may provide synergistic anti-inflammatory therapeutic effects.
Dr. Fred Grossman, Coya's Chief Medical Officer commented, ' We believe the encouraging results of this study provide support for our multi-targeted combination approach as a potentially viable treatment option for serious and life-threatening conditions of high unmet need driven by chronic inflammation and Treg dysfunction, for which currently available treatments provide limited benefits.'
Summary of Study Results
Following pro-inflammatory activation of myeloid cells co-cultured with Tregs, the addition of COYA 301 (LD IL-2) alone enhanced Treg suppressive function by 15%. Similarly, when GLP-1RA alone was added to the system, Treg suppressive function increased by 20%. In contrast, when COYA 303 was added to the cell system a statistically significant increase in Treg suppressive function of 42% (p < 0.001) was observed, when compared to the increase observed with each of the single agents.
Consistent with these results, treatment with COYA 303 promoted Treg survival by modulating the apoptotic pathway. COYA 303 significantly reduced BAX transcript levels during prolonged incubation (p < 0.01). These findings suggest a direct effect of COYA 303 supporting Treg survival through the inhibition of Treg apoptosis.
These data show that the combination approach of COYA 303 enhances Treg suppressive function in highly inflammatory microenvironments, while also promoting Treg survival by preventing apoptosis.

Omada Health IPO signals healthier market, avoids 'down-round' trend
The IPO market is starting to feel healthier. Omada Health, a 14-year-old company providing virtual care for chronic conditions like diabetes and hypertension between office visits, closed its first trading day on Friday at $23 a share, a 21% jump from the IPO price of $19. The IPO valued the company just above $1 billion (excluding employee options), a figure that's nearly identical to Omada's last private valuation of $1 billion set in its previous VC round. The debut is one of the first among recent IPOs that was not a so-called down-round. Many of the latest public listings, including Hinge, ServiceTitan, and Reddit, priced below their private market highs, though have faired well as public companies. For founder and CEO Sean Duffy, the successful public offering validates his decision to start a company that he believed the market desperately needed. In 2011, he dropped out of Harvard Medical School after realizing that chronic illness patients required more continuous support than the existing healthcare system delivered. Before the offering, he owned 4.1% of the company, according to Omada's offering document. Other significant shareholders included Revelation Partners (10.9%), US Venture Partners (9.9%), Andreessen Horowitz (9.6%), and FMR (9.3%). Duffy told TechCrunch that over his 14-year journey as a founder, he had many harrowing moments. "I didn't think our series A was going to come together because we were working on this commercial deal that didn't materialize, and that spooked one investor," he said. "As a young business, something tries to kill you every month," he continued. "And then as the business grows, it turns into like every quarter or six months, year, two years." One of the recent challenges for many digital health businesses is navigating the "collapse" of the market post-COVID boom. Omada steered through the turbulent times by seeking new, rising markets. It recently expanded its offerings to include diet management support for GLP-1 patients.

H.C. Wainwright Initiates Coverage of Akebia Therapeutics (AKBA) With Buy Rating
Matthew Caufield, an analyst from H.C. Wainwright, initiated coverage of Akebia Therapeutics, Inc. (NASDAQ:AKBA) with a Buy rating and a $8 price target, on June 4. The analyst gave the optimistic rating due to the company's VAFSEO product and its potential in the CKD anemia market. VAFSEO is an approved treatment for anemia in adults with chronic kidney disease on dialysis. According to the analyst, the treatment is gaining considerable momentum among dialysis organizations, and this trend is anticipated to support near-term growth. He expects VAFSEO's ongoing launch to offset the effect of generics on AURYXIA, another product by Akebia Therapeutics, Inc. (NASDAQ:AKBA) that deals with hyperphosphatemia. A biopharmaceutical team in a laboratory analyzing new compounds to develop therapeutics. The analyst also reasoned that Akebia Therapeutics, Inc. (NASDAQ:AKBA) is positioned for success as it has secured contracts that cover almost all dialysis patients in the US. VAFSEO offers flexibility in its dosing regimen, ranging from 150mg to 600mg, making it a factor that allows for personalized treatment and potentially growing prescriptions. Caufield pointed out VAFSEO's oral administration as another reason supporting the optimistic rating, giving it an advantage over existing therapies, such as iron supplementation and erythropoiesis-stimulating agents. Akebia Therapeutics, Inc. (NASDAQ:AKBA) is a biopharmaceutical company that develops and commercializes drugs to treat metabolic and renal diseases.

New coronavirus discovered in China ‘only small step' from infecting humans
A new coronavirus discovered in China is only a small step from mutating and causing another global pandemic, experts have warned. Scientists believe the variant, called HKU5-CoV-2, may infect a broader range of animals than Covid-19 – which caused millions of deaths – and may have more potential for jumping between species. US researchers fear that HKU5-CoV-2, found in China, in February, could also infect humans, leading to a widespread outbreak. The new study, published in Nature Communications, looked at a lesser-known group of coronaviruses called merbecoviruses, which includes HKU5 and MERS-CoV, which is responsible for the deadly Middle East Respiratory Syndrome. The team from Washington State University looked at how the new pathogen interacts with human cells. They found that a small change in the virus's spike protein could allow it to attach to human ACE2 cells in people's throats, mouths and noses. HKU5-CoV-2 can infect and replicate inside human cells in both the airways and gut. According to the World Health Organisation, about 35 per cent of people infected with Middle East Respiratory Syndrome die. Since 2012, some 27 countries have reported cases, leading to 858 known deaths due to the infection, which spread from camels. But when HKU5 was discovered in February, scientists warned against exaggerating the risks because it does not enter human cells as readily as Sars-CoV-2, which caused Covid-19. HKU5 was first detected in bats by scientists from the Chinese laboratory where some say Covid originated in 2019. Prof Michael Letko, a virologist who co-led the study, said: 'HKU5 viruses in particular really hadn't been looked at much, but our study shows how these viruses infect cells. 'What we also found is HKU5 viruses may be only a small step away from being able to spill over into humans.' When Covid-19 emerged it was widely blamed on markets in China where different breeds of wild animal are kept caged and often slaughtered close to other animals. Meat is sold at the open-air stalls. Critics said the markets were the perfect breeding ground for new zoonotic diseases – those that spread to humans – to emerge. The scientists, whose experiments studied how the new pathogen interacts with human cells, believe the virus would have to carry certain mutations if it were to infect humans. 'These viruses are closely related to MERS, so we have to be concerned if they ever infect humans,' Prof Letko said. 'While there's no evidence they've crossed into people yet, the potential is there and that makes them worth watching.'
