Coya Therapeutics

Coya Therapeutics Unleashing the power of Tregs to tackle neurodegenerative and autoimmune diseases. 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 sust

ained inflammation and oxidative stress resulting in lack of homeostasis of the immune system. Coya’s 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 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. Coya’s mission is focused on the advancement of innovative therapeutic approaches to address the significant unmet medical needs of patients with serious neurodegenerative, autoimmune, and metabolic diseases.
