Coya to Present Additional Biomarker and Brain Imaging Data for COYA 301 in Alzheimer’s Disease (AD) at the LD Micro Conference on June 7, 2023

•  Coya previously announced results from an open-label study of COYA 301 in 8 patients with Alzheimer’s disease (AD) that resulted in a statistically significant improvement in cognitive function, as measured by the Mini-Mental State Examination test (MMSE).
• Coya to present on additional blood biomarker data for pro- inflammatory cytokines Tumor Necrosis Factor alpha (TNF-α), Interleukin 6 (IL-6), and Interleukin 1- Beta (IL-1β) from the recently presented 8 patient investigator-initiated AD study
• Increased systemic levels of TNF-α, IL-6, and IL-1β have been associated with cognitive decline and may play a role in the pathogenesis and pathophysiology of AD
• Coya also to provide a case report documenting pre- and post-treatment Positron Emission Technology (PET) imaging illustrating the impact of COYA 301 treatment on brain inflammation in one patient that showed cognitive improvement

Coya Therapeutics, Inc. (NASDAQ: COYA) (“Coya” or the “Company”), a clinical-stage biotechnology company developing multiple therapeutic programs intended to enhance Treg function, including biologics and cell therapies, announced today that it will report new biomarker and brain imaging data from its open-label proof-of-concept clinical study for COYA 301 in patients with Alzheimer’s Disease at the LD Micro Conference:

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 lead 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. For more information about Coya, please visit www.coyatherapeutics.com
