Investment Thesis

▲ Bull case

Coya Therapeutics is positioned to capitalize on a compelling scientific rationale for COYA 302, which targets regulatory T-cell (Treg) dysfunction—a root cause of neuroinflammation in neurodegenerative diseases like ALS and FTD. The company’s dual-mechanism approach combining low-dose IL-2 and CTLA-4 Ig has demonstrated consistent biological activity across multiple investigator-initiated studies, including statistically significant and sustained increases in Treg numbers and suppressive function as early as two weeks post-dosing in FTD patients, alongside stabilization of cognitive metrics such as MoCA and CDR-FTLD over 22 weeks. These findings are reinforced by biomarker data showing reduced pro-inflammatory signaling and enhanced anti-inflammatory pathways, suggesting disease-modifying potential rather than mere symptomatic relief. The FDA’s Fast Track designation for COYA 302 in ALS, coupled with IND acceptance for FTD, validates the therapeutic promise and accelerates regulatory pathways, potentially enabling rolling reviews and priority consideration. This scientific momentum is underappreciated by the market, which remains focused on near-term cash burn rather than the accumulating evidence of target engagement and biological efficacy that could derisk future pivotal trials. Coya’s ability to replicate Treg enhancement across ALS and FTD indications points to a platform technology with broad applicability, potentially transforming it from a single-asset company into a multi-indication biologics leader.
Financial discipline and strategic non-dilutive funding have extended Coya’s cash runway well beyond imminent clinical milestones, reducing near-term financing risk. As of March 31, 2026, the company held $50.7 million in cash and cash equivalents, with management projecting runway into the second half of 2027—exceeding the expected 1Q 2027 topline readout of the ALSTARS trial. This position was strengthened by $8.4 million in non-dilutive funding from Dr. Reddy’s Laboratories in 2025 and an additional $11.1 million private placement in January 2026, minimizing reliance on volatile equity markets. Unlike many peers facing dilutive financings amid clinical uncertainty, Coya has preserved shareholder value while advancing key programs. The ALSTARS trial is actively enrolling across more than 20 U.S. sites and newly activated Canadian sites following Health Canada CTA acceptance, with recruitment expected to accelerate due to revised inclusion/exclusion criteria. The company’s ability to maintain operational execution without urgent capital needs allows management to focus exclusively on trial progression and data readout timing, a significant advantage in a sector where cash constraints often force premature trial modifications or delays.
Coya is advancing dual clinical programs in ALS and FTD—two high-unmet-need indications with combined peak sales potential estimated at $2–$4 billion—while retaining full global rights to both, creating substantial long-term value optionality. The ALSTARS trial (NCT07161999) is a Phase 2, randomized, placebo-controlled study designed to capture clinically meaningful endpoints in ALS, with topline data expected in 1Q 2027. Parallel progress in FTD includes FDA clearance for a Phase 2a study and plans to initiate in Q2 2026, building on encouraging investigator-initiated data showing stabilized cognition and enhanced Treg function. Notably, the company’s preclinical candidate COYA 303 (low-dose IL-2 + GLP-1 RA) targets Alzheimer’s disease, leveraging emerging biomarker synergy data despite recent setbacks in semaglutide monotherapy trials. This pipeline diversification reduces reliance on any single indication and positions Coya to benefit from converging trends in immuno-neurology, where Treg modulation is increasingly viewed as a central mechanism in neurodegeneration. The market appears to be pricing COYA as a binary ALS bet, overlooking the cumulative de-risking from FTD progress, biomarker validation, and platform extensibility—factors that could support a premium valuation upon positive clinical readouts.

▼ Bear case

Coya Therapeutics faces significant clinical and regulatory risks that the market may be underestimating, particularly given the lack of confirmatory data from large-scale, randomized controlled trials for COYA 302. Despite encouraging biomarker and immunological signals from small investigator-initiated studies in ALS and FTD—such as increased Treg function and stabilized cognitive scores over 22 weeks—these findings do not constitute proof of efficacy in altering disease progression. The ALSTARS trial, while Phase 2 and placebo-controlled, remains underpowered to detect clinically meaningful functional endpoints like ALSFRS-R change with high confidence, and any positive signal would require replication in larger pivotal trials. History is replete with neurodegenerative therapies showing promising immunomodulatory signals in early studies (e.g., anti-inflammatory cytokines, microglial modulators) that failed in Phase 3 due to lack of functional benefit. The company’s reliance on exploratory biomarkers like NfL, 4-HNE, and Treg surrogates—instead of established clinical endpoints—increases the risk of misinterpreting biological activity as therapeutic benefit. Furthermore, the Fast Track designation, while facilitating regulatory interaction, does not alter the evidentiary bar for approval and may create overconfidence in the likelihood of success.
Financial sustainability remains a concern despite recent fundraising, as Coya continues to operate with substantial quarterly cash burn and no near-term revenue prospects. The company reported a net loss of $7.2 million in Q1 2026 and $21.2 million for FY 2025, driven by escalating R&D expenses ($16.7 million in 2025) tied to clinical advancement. Although cash and equivalents reached $50.7 million as of March 31, 2026, this reflects proceeds from the January 2026 private placement ($11.1 million gross) and prior non-dilutive funding—sources that are non-recurring. Collaboration revenue, while growing to $7.9 million in 2025, remains minimal and heavily dependent on milestone payments from partners like Dr. Reddy’s Laboratories, which are unlikely to recur at similar scale without new deals. With no approved products and no near-term commercialization horizon (ALSTARS topline not expected until 1Q 2027), Coya will likely require additional financing before achieving profitability, potentially leading to shareholder dilution if clinical results disappoint. The company’s operating expenses are structurally high for its stage, and any delay in trial readout or unfavorable data could rapidly erode the current cash runway, which management projects only into H2 2027—a timeline that leaves little room for error.
Competitive and scientific uncertainties in the Treg-modulation space pose a growing threat to Coya’s differentiated positioning, particularly as larger pharmaceutical companies enter the neuroimmunology arena with deeper resources. While Coya emphasizes its Treg-enhancing biologics, Treg-derived exosomes, and autologous Treg cell therapy platforms, the scientific validity of targeting Tregs in neurodegeneration remains incompletely established, and competing mechanisms—such as anti-amyloid, anti-tau, TREM2 agonists, or broad anti-inflammatories—are advancing in parallel. Recent setbacks in Alzheimer’s immunotherapy (e.g., semaglutide’s lack of clinical efficacy despite biomarker changes) raise doubts about whether modulating peripheral immune markers like Tregs translates to meaningful central nervous system outcomes. Moreover, COYA 302’s composition—low-dose IL-2 and CTLA-4 Ig—is not novel; similar combinations have been explored in autoimmune diseases with mixed results, and the immunosuppressive risks of CTLA-4 Ig (e.g., as seen in abatacept) require careful long-term monitoring in chronic dosing scenarios. The company’s reliance on subcutaneous administration may also limit patient convenience and adherence compared to emerging oral or less frequent dosing regimens in development elsewhere. If larger players with superior manufacturing, scale, and clinical trial infrastructure demonstrate similar or better Treg modulation with improved safety profiles, Coya’s first-mover advantage could diminish rapidly, leaving it vulnerable to being outpaced in a crowded and evolving therapeutic landscape.
