Recent Corporate Highlights Submitted to FDA on June 30, 2025, additional nonclinical data to support the start of the COYA 302 Phase 2 trial in patients with ALS Published results of scientific research linking inflammation and oxidative stress to the progression of Parkinson's Disease (PD). Study demonstrated correlation between peripheral pro-inflammatory mechanisms, particularly monocytes and oxidative stress, in the progression and severity PD. It was published in the scientific journal Frontiers of Immunology Announced U.S. patent (US 12,312,389 B2) for a stable ready-to-use liquid IL-2 formulation; Coya holds exclusive in-vivo rights across multiple indications Upcoming Expected Catalysts for 2025 Decision from the US FDA on the IND for COYA 302 in ALS, expected by or before August 29, 2025 Upon IND acceptance and first patient dosing of COYA 302 in ALS, Coya will receive milestone payments of $8.4 million from strategic partner, Dr. Reddy's Laboratories (DRL) ALS Biomarker data. Publication of longitudinal data on Neurofilament Light Chain (NfL) and oxidative stress markers in tracking progression and survival in patients with ALS Report new proteomics data from the completed investigator-initiated, 21-week, double-blind, placebo-controlled, exploratory Phase 2 study of low-dose interleukin-2 (LD IL-2) in patients with Alzheimer's disease (AD) Top-line clinical data release for an investigator-initiated trial combining LD IL-2 + CTLA4-Ig in patients with Frontotemporal Dementia (FTD) Top-line data for COYA 303 in an in-vivo inflammatory animal model Filing of IND for the COYA-302 Phase 2 trial in patients with FTD* (*Clinical trial will be initiated after FDA IND approval for FTD) Coya's Chief Executive Officer Arun Swaminathan, Ph.D. commented, "As we look ahead, we are focused on several key catalysts, including a decision from the FDA on our IND application for COYA 302 in ALS, anticipated by the end of August. We are encouraged by the growing body of data supporting our regulatory T cell enhancement approach, including the recent findings from the investigator-initiated trial in FTD and promising pre-clinical results with COYA 303. These advances strengthen our confidence in the potential of COYA 302 in neurodegenerative diseases like ALS and FTD." Coya's Chief Medical Officer Dr. Fred Grossman commented, "We look forward to the FDA's decision on our IND submission for COYA 302 in ALS, which represents a significant milestone for our lead program. Pending clearance, we are prepared to initiate our controlled Phase 2 clinical trial in ALS. We also plan to submit an IND for FTD by the end of the year." Financial Results As of June 30, 2025, Coya had cash and cash equivalents of $29.8 million. Collaboration revenues were $0.2 million for the three months ended June 30, 2025, compared to $3.4 million for the three months ended June 30, 2024, a change of approximately $3.3 million. The decrease was primarily due to the immediate recognition of license revenue upon executing the First Amendment to the DRL Development Agreement during the three months ended June 30, 2024. Research and development expenses were $3.7 million for the three months ended June 30, 2025, compared to $4.6 million for the three months ended June 30, 2024, a decrease of approximately $0.9 million. The decrease was primarily due to a $1.2 million decrease in our preclinical expenses primarily due to our preclinical work on COYA 302 in ALS, partially offset by a $0.2 million increase in internal research and development expenses, and a $0.1 million increase in sponsored research. General and administrative expenses were $2.9 million for the three months ended June 30, 2025, and $2.1 million for the three months ended June 30, 2024, an increase e of approximately $0.8 million. The increase was primarily due to a $0.3 million increase in stock-based compensation, a $0.4 million increase in professional services, and a $0.1 million increase in investor relation related expenses. Net loss was $6.1 million for the three months ended June 30, 2025, compared to net loss of $2.9 million for the three months ended June 30, 2024. About COYA 302 COYA 302 is an investigational and proprietary biologic combination therapy with a dual immunomodulatory mechanism of action intended to enhance the anti-inflammatory function of regulatory T cells (Tregs) and suppress the inflammation produced by activated monocytes and macrophages. COYA 302 comprises proprietary low dose interleukin-2 (LD IL-2) and CTLA-4 Ig and is being developed for subcutaneous administration for the treatment of patients with ALS. These mechanisms may have additive or synergistic effects. COYA 302 is an investigational product not yet approved by the FDA or any other regulatory agency. About COYA 303 COYA 303 is an investigational biologic combination of COYA 301 and a glucagon-like-peptide-1 receptor agonist (GLP-1 RA) designed for subcutaneous administration. In a preclinical study, COYA 303 exhibited a dual immunomodulatory mechanism of action resulting in an additive/synergistic anti-inflammatory effect, which the Company believes was due to increased Treg function and suppressed pro-inflammatory myeloid cells and responder T cells. 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. This cellular dysfunction may lead to 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.

The delay hits the biotech in an early stage of drug development in which companies submit preclinical data to the FDA and request to into human studies.\n The FDA has missed the date for Coya Therapeutics’ investigational new drug (IND) application, citing a lack of resources and its current workload as reasons for the delay, according to a legal filing from the biotech.On July 29, the federal drug agency told Coya it would not meet the initial review goal date of July 30, according to a Securities and Exchange Commission filing from the Houston-based biotech. If approved, the IND application would allow Coya to launch a phase 2 trial for its investigational amyotrophic lateral sclerosis (ALS) treatment.The FDA said it would deliver a decision before or by Aug. 29, according to the filing.As of publication Thursday morning, the FDA has not responded to Fierce Biotech’s request for comment.The delay hits the biotech in an early stage of drug development in which companies submit preclinical data to the FDA and request to move the candidate into human studies.For Coya, the delay will stretch out the time—and the company’s cash runway—that the biotech must wait to see if it can start clinical trials for COYA 302, its lead biologic investigational product that the biotech dubs a \"pipeline in a product.\"The asset is a combination of Coya’s LD IL-2 candidate called COYA 301, plus a CTLA4-Ig, for the potential treatment of ALS, dementia, Parkinson’s disease and Alzheimer’s disease.As of March 31, Coya had $35.5 million on hand, according to first-quarter earnings.Small biotechs are typically tight on cash, with operations and funding plans tied to agency approvals and requirements.In April, more than 200 biotech leaders penned a letter expressing concern over the FDA’s capacity after mass federal layoffs, specifically for small biotechs that depend on investor backing to meet agency standards. Under President Donald Trump, the FDA has undergone an extreme overhaul, losing at least 3,500 full-time employees and a large portion of the agency’s former leadership.At the time of the mass layoffs, the Department of Health and Human Services said the workforce reduction “will not affect drug, medical device or food reviewers, nor will it impact inspectors.”  In June, Trump’s pick for FDA Commissioner, Marty Makary, M.D., said the agency was “on track to meet all the PDUFA targets and that morale is good and improving at the agency.”The leader said this two days after KalVista Pharmaceuticals announced that the FDA said it would miss the biotech’s June 17 PDUFA date due to “heavy workload and limited resources.” The Cambridge, Mass.-based biotech had been expecting the FDA to either approve or reject the company’s oral plasma kallikrein inhibitor, sebetralstat, for hereditary angioedema (HAE). But the FDA informed the company that it could have to wait up to four weeks for the agency to make the call. On July 7, the biotech said the agency had approved its drug under the brand name Ekterly as a new, oral treatment option for acute attacks of HAE.    The newly restructured agency has also missed approval decision deadlines for GSK’s IL-5 antibody Nucala, Novavax’s protein-based COVID-19 vaccine, and Stealth BioTherapeutics’ ultrarare genetic disease candidate.
