Coya Therapeutics’ COYA 302 Treating ALS Proves Effective In Proof-Of-Concept Academic Clinical Study

By David Willey, Benzinga

Coya Therapeutics, Inc. (NASDAQ: COYA) recently reported 48-week clinical data for its proof-of-concept open-label study in 4 ALS patients indicating that treatment with COYA 302 appeared to significantly ameliorate disease progression (stopping progression in all patients at 24 weeks with minimal decline at 48 weeks.) This was in a patient cohort who was declining prior to entry into the study.

Four ALS patients with a mean decline of -1.1 points/month in the Revised ALS Functional Rating Scale (ALSFRS-R) score prior to study initiation, were treated for 48 consecutive weeks with COYA 302 and were evaluated for safety and tolerability, Treg suppressive function, serum biomarkers of oxidative stress and inflammation, and clinical functioning as measured by the ALSFRS-R scale. Following the administration of COYA 302 for 48 weeks, patients were evaluated over an 8-week washout period.

During the 48-week treatment period, COYA 302 appeared to be well tolerated. The most common adverse event was mild injection-site reactions. No patient discontinued the study, and no deaths or other serious adverse events were reported.

Preliminary efficacy of COYA 302 was measured by the ALSFRS-R scale, a validated rating tool for monitoring the progression of disability in patients with ALS. The mean (±SD) ALSFRS-R scores at week 24 (33.75 ±3.3) and week 48 (32 ±7.8) after initiation of treatment with COYA 302 were not statistically different compared to the ALSFRS-R score at baseline (33.5 ±5.9), indicating significant amelioration in the progression of the disease over the 48-week treatment period.

Treg suppressive function, expressed as percentage of inhibition of proinflammatory T cell proliferation, showed a statistically significant increase over the course of the treatment period and was significantly reduced at the end of the 8-week washout post-treatment period. Treg suppressive function at 24 weeks (79.9±9.6) and 48 weeks (89.5±4.1) were significantly higher compared to baseline (62.1±8.1) (p<0.01), suggesting enhanced and durable Treg suppressive function over the course of treatment. In contrast, Treg suppressive function (mean ±SD) was significantly decreased at the end of the 8-week washout period compared to end-of-treatment at week 48 (70.3±8.1 vs. 89.5±4.1, p <0.05).

The study also evaluated serum biomarkers of inflammation, oxidative stress, and lipid peroxides. The available data up to 16 weeks after initiation of treatment suggest a decrease of these biomarker levels, which is consistent with the observed enhancement of Treg function. The evaluation of the full biomarker data is ongoing.

About Coya Therapeutics, Inc.Headquartered in Houston, TX, Coya Therapeutics, Inc. (Nasdaq: COYA) is a clinical-stage biotechnology company developing proprietary treatments focused on the biology and potential therapeutic advantages of regulatory T cells (“Tregs”) to target systemic inflammation and neuroinflammation. Dysfunctional Tregs underlie numerous conditions including neurodegenerative, metabolic, and autoimmune diseases, and this cellular dysfunction may lead to a sustained inflammation and oxidative stress resulting in lack of homeostasis of the immune system. Coya’s investigational product candidate pipeline leverages multiple therapeutic modalities aimed at restoring the anti-inflammatory and immunomodulatory functions of Tregs. Coya’s therapeutic platforms include Treg-enhancing biologics, Treg-derived exosomes, and autologous Treg cell therapy. Coya’s 300 Series product candidates, COYA 301 and COYA 302, are biologic therapies intended to enhance Treg function and expand Treg numbers. COYA 301 is a cytokine biologic for subcutaneous administration intended to enhance Treg function and expand Treg numbers in vivo, and COYA 302 is a biologic combination for subcutaneous and/or intravenous administration intended to enhance Treg function while depleting T effector function and activated macrophages. These two mechanisms may be additive or synergistic in suppressing inflammation.
