Introduction

Coya Therapeutics, a clinical-stage biotechnology company, has been making waves in the realm of neurodegenerative diseases with its innovative approach to enhancing regulatory T cell (Treg) function. As the company navigates the ever-evolving landscape of drug development, its unwavering commitment to advancing groundbreaking therapies has positioned it as a key player in the fight against debilitating conditions.

Company Background

Established in 2020, Coya Therapeutics has quickly gained recognition for its diversified product candidate pipeline, which encompasses both ex vivo and in vivo approaches aimed at restoring the suppressive and immunomodulatory functions of Tregs. The company's core focus lies in targeting Treg dysfunction, which has been identified as a crucial pathophysiological component in neurodegenerative, autoimmune, and metabolic diseases – areas where new and effective therapies are urgently needed.

Key Developments

In 2021, Coya adopted the 2021 Equity Incentive Plan, providing for the granting of various equity-based awards to employees, officers, directors, and other service providers. The company also entered into a License Agreement with ARScience Biotherapeutics, Inc. to acquire an exclusive, royalty-bearing license for two patents related to its Treg-enhancing biologics program.

The following year, Coya entered into an Amended and Restated Patent, Know-How and License Agreement with The Methodist Hospital to license intellectual property and know-how to develop products and services. Additionally, the company entered into a Sponsored Research Agreement with Houston Methodist Research Institute to fund research and raised capital through the issuance of convertible promissory notes.

In 2023, Coya achieved a significant milestone by completing its initial public offering, raising $14.25 million in gross proceeds. The company also entered into an exclusive License and Supply Agreement with Dr. Reddy's Laboratories Ltd. to in-license the company's proposed abatacept biosimilar for use in the development of COYA 302 combination product for neurodegenerative diseases. This agreement included upfront, milestone, and royalty payments potentially worth up to $23 million. Furthermore, Coya entered into a Development and License Agreement with Dr. Reddy's, granting them an exclusive, royalty-bearing license to commercialize COYA 302 in certain territories.

Lead Asset and Clinical Progress

Coya's lead asset, COYA 302, is a Treg-enhancing biologic that combines the company's proprietary low-dose interleukin-2 (LD IL-2) technology, COYA 301, with the immunomodulatory drug abatacept. This combination therapy has the potential to provide a sustained and durable effect on Coya's initial indications, which include neurodegenerative disorders. The company's research and clinical efforts have led it to believe that combination biologics using LD IL-2 as a backbone modality could be the best way to treat neurodegenerative conditions driven by the complexity of various pathways.

In a significant development, Coya recently announced positive results from an investigator-initiated, placebo-controlled Phase 2 study of LD IL-2 in patients with mild to moderate Alzheimer's disease (AD). The study, led by Drs. Alireza Faridar and Stanley Appel from the Houston Methodist Research Institute, met its primary and secondary endpoints, demonstrating that LD IL-2 treatment is safe and well-tolerated in AD patients. Importantly, the LD IL-2 q4wks (every four weeks) regimen led to significant improvements in cerebrospinal fluid (CSF) soluble Aβ42 levels, an indicator of amyloid pathology, and showed a promising trend in stabilizing cognitive function.

These positive results further strengthen Coya's confidence in advancing LD IL-2 treatments and potential combinations, such as COYA 302, for Alzheimer's and related neurodegenerative conditions. The company's findings have also highlighted the advantages of combination biologics in addressing the complex pathways involved in these diseases, as well as the potential benefits of scalability and cost-effectiveness.

Pipeline Expansion

Coya's pipeline expansion efforts have not been limited to Alzheimer's disease alone. In January 2024, the company announced that it is expanding the application of COYA 302 beyond amyotrophic lateral sclerosis (ALS) to include frontotemporal dementia (FTD) and Parkinson's disease (PD). This move underscores Coya's commitment to exploring the versatility of its combination therapy approach in tackling a broader range of neurodegenerative conditions.

Financials

Coya Therapeutics reported collaboration revenue of $3.55 million for the nine months ended September 30, 2024, related to the DRL Development Agreement for the commercialization of COYA 302 in certain territories. The company's research and development expenses increased significantly to $9.93 million, up from $3.89 million in the same period of the prior year, primarily due to the advancement of COYA 302 in preclinical studies. General and administrative expenses also increased to $6.75 million, compared to $5.46 million in the prior year period, largely due to increased stock-based compensation and employee headcount.

For the most recent fiscal year, Coya reported annual revenue of $6 million, with a net loss of $8 million. The company's annual operating cash flow and free cash flow both stood at negative $11.19 million. In the third quarter of 2024, Coya reported no revenue and a net loss of $4.02 million. The company did not recognize any collaboration revenue in Q3 2024 due to an increase in budgeted spending for COYA 302 as a result of communication with the FDA requiring additional non-clinical data prior to initiating the planned Phase 2 study.

Furthermore, in October 2024, Coya reported the closing of a $10 million private placement, with the majority of investors being existing institutional stockholders. This strategic funding, coupled with the company's existing cash and cash equivalents of $31 million as of September 30, 2024, provides Coya with a solid financial foundation to advance its clinical programs and pipeline development efforts.

During the third quarter of 2024, Coya reported a net loss of $4 million and a net loss of $12 million for the nine-month period ended September 30, 2024. The company's research and development expenses increased by $6 million from the same period in 2023, reflecting the advancement of its preclinical activities, particularly the preparation of COYA 302 for its initial IND filing and the launch of a Phase 2 clinical trial.

Liquidity

As of September 30, 2024, Coya Therapeutics reported cash and cash equivalents of $31.06 million. The additional $10 million raised through the private placement in October 2024 further bolstered the company's liquidity position. This robust cash position is expected to provide Coya with sufficient resources to fund its ongoing research and development activities, as well as support the advancement of its clinical programs into 2026.

The company's financial health is further reflected in its liquidity ratios. Coya has a debt-to-equity ratio of 0, indicating no long-term debt on its balance sheet.
