• COYA 301 (biologic monotherapy) clinical and biomarkers data in patients with Alzheimer's disease (AD) to be presented in 1H 2023 and 2H 2023
• COYA 302 (biologics combination therapy) clinical and biomarkers data in patients with Amyotrophic Lateral Sclerosis (ALS) to be presented in Q1 2023

HOUSTON--(BUSINESS WIRE)--Coya Therapeutics, Inc. (NASDAQ: COYA) ("Coya" or the "Company"), a clinical-stage biotechnology company developing multiple therapeutic platforms intended to enhance Treg function, including biologics and cell therapies, today announced plans for presenting proof-of-concept clinical data from two open-label academic studies conducted at Houston Methodist Hospital, under the leadership of Professor Stanley Appel, MD, the Chair of Coya's Scientific Advisory Board.

"We believe that the proof-of-concept clinical data from COYA 301 as monotherapy, and COYA 302 (biologics combination therapy) from early academic studies in patients with AD and ALS are encouraging and support further development of our biologic investigational candidates. We will be presenting these study data at upcoming scientific conferences this year, starting in the first quarter of 2023," stated Howard Berman, Ph.D., Chief Executive Officer of Coya. "We are committed to developing COYA 301 and COYA 302 across multiple therapeutic areas, including neurodegenerative and autoimmune diseases," Dr. Berman added. The Company anticipates announcing more details about the presentations in the future.

COYA 301 (biologic monotherapy) clinical and biomarkers data in patients with Alzheimer's disease (AD) to be presented in 1H 2023 and 2H 2023

The first academic study with COYA 301 provides proof-of concept data, including biological activity, serum biomarkers of inflammation, tolerability and preliminary clinical outcomes in patients with AD. Alzheimer's disease is the most common form of dementia, affecting over 6 million people in the US. About 1 in 9 people (10.7%) age 65 and older has AD.¹

COYA 302 (biologics combination therapy) clinical and biomarkers data in patients with Amyotrophic Lateral Sclerosis (ALS) to be presented in Q1 2023

The second academic COYA 302 clinical trial evaluated the tolerability, biological activity and preliminary efficacy of COYA 302 in patients with ALS and included assessment of serum biomarkers of inflammation and oxidative stress. ALS, also known as Lou Gehrig's disease, is a neurodegenerative life-threatening disease affecting nerve cells in the brain and spinal cord. People with ALS progressively lose the ability to speak, eat, move, and breathe. There are over 30,000 patients with ALS in the US, and about 5,000 new patients are diagnosed every year.²

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. For more information about Coya, please visit .
