HOUSTON / May 10, 2023 / Business Wire / Coya Therapeutics, Inc. (Nasdaq: COYA) (“Coya” or the “Company”), a clinical-stage biotechnology company developing biologics and cell therapies intended to enhance the function of Regulatory T Cells (Tregs), today announced its financial results for the first quarter ended March 31, 2023, and provided a clinical and business update.

Q1 2023 and Recent Highlights (Unaudited)

• Announced positive results from a proof-of-concept, open-label academic clinical study of COYA 302 in Amyotrophic Lateral Sclerosis (ALS) illustrating halting of disease progression at 24 weeks with minimal decline at 48 weeks. Study data were presented at the 2023 Muscle Dystrophy Association Conference;
• Announced the presentation of results from an academic clinical study in eight patients with mild to moderate Alzheimer’s Disease (AD) with Coya’s COYA 301, its proprietary investigational biologic, evaluating its safety and tolerability, biological activity, blood biomarkers and preliminary efficacy. The presentation will be made at the 2023 Keystone Symposia Neurodegeneration: Biology Guiding the Next Generation of Therapeutic Development, to be held at Whistler, British Columbia, Canada, from May 15-19th, 2023;
• Appointed Arun Swaminathan, Ph.D. as Chief Business Officer, who negotiated significant licensing transactions with two top-ten global pharmaceutical companies while at Alteogen, Inc.;
• Entered into a worldwide agreement with Dr. Reddy’s Laboratories Limited. (Dr. Reddy’s)(NYSE: RDY), whereby Coya in-licensed Dr. Reddy’s proposed Abatacept biosimilar, for the development of COYA 302 the Company’s combination product candidate for the treatment of certain neurodegenerative diseases, and out-licensed to Dr. Reddy’s, COYA 301, the Company’s low dose Interleukin 2 (IL-2) product candidate to permit the commercialization by Dr. Reddy’s of COYA 302 in territories not otherwise granted to Coya;
• Expanded its exclusive worldwide licensing agreement with ARScience Biotherapeutics for the development and commercialization of COYA 301;
• Reported preclinical data in an animal model of Alzheimer’s disease supporting the role of expanded Regulatory T Cells (Tregs) as a target for development of potential disease modifying treatments for this form of dementia;
• Closed an Initial Public Offering of common stock and warrants on January 3, 2023 and overallotment option on January 25, 2023, for aggregate gross proceeds of approximately $16.4 million and net proceeds of $14.1 million.

“In Q1, we were pleased to report promising positive clinical data for COYA 302, illustrating that this biologic combination halted disease progression in ALS patients at 24 weeks with minimal decline at 48 weeks,” stated Howard Berman, Ph.D., Chief Executive Officer of Coya. “Subsequent to quarter end, we bolstered our leadership team with the addition of an accomplished Chief Business Officer, Arun Swaminathan, Ph.D. We are excited about the potential for Arun to unlock attractive business development alliances and strategic transactions. We also announced an upcoming presentation in Alzheimer’s Disease (AD) data with COYA 301 at the 2023 Keystone Symposia on Neurodegeneration to be held from May 15 – 19 that we believe may further illustrate the potential benefit of enhancing Tregs in dementia. Looking ahead, we’re excited to deliver more data and execute on milestones to maximize shareholder value,” concluded Dr. Berman.

Financial Results (Unaudited)

As of March 31, 2023, Coya had cash and cash equivalents of $16.3 million.

Research and development (R&D) expenses were $1.2 million for the quarter ended March 31, 2023, compared to $1.0 million for the quarter ended March 31, 2022. The change in research and development expense of approx. $0.2 million was primarily due to increasing Coya’s clinical trial expenses as well as an increase in employee headcount to support the Company’s continued trials. The Company believes that R&D spending in 2023 will increase over 2022 spending levels and will be focused primarily on advancing COYA 301 and 302.

General and administrative expenses were $1.7 million for the quarter ended March 31, 2023, and $0.7 million for the quarter ended March 31, 2022, a change of approximately $1.0 million. The change was primarily due to an increase in personnel related expenses due to increases in employee headcount and an increase in professional fees and consulting fees as the Company expanded its operations. The Company expects general and administrative costs to continue to grow in 2023 as Coya expands its business development activities as well as incurs additional costs associated with being a public company including higher expense for investor and public relations, director and officer insurance, and audit and compliance.

Net loss was $2.7 million for the quarter ended March 31, 2023, compared to net loss of $1.7 million for the quarter ended March 31, 2022. Net loss reflects the changes in operating expenses discussed above as well as $0.2 million of other income for the quarter ended March 31, 2023, principally interest, earned on the Coya’s cash balances.

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 www.coyatherapeutics.com.
