Serina Therapeutics Reports Second Quarter 2025 Financial Results and Provides Business Highlights

HUNTSVILLE, Aug. 11, 2025 (GLOBE NEWSWIRE) -- Serina Therapeutics, Inc. (“Serina”) (NYSE American: SER), a clinical-stage biotechnology company advancing its lead IND candidate, SER-252, for advanced Parkinson's disease, enabled by its proprietary POZ Platform™ drug optimization technology, today announced its financial results for the second quarter ended June 30, 2025, along with key recent updates. “We’re proud of the momentum we’ve built across our development programs. With SER-252 on track to enter the clinic later this year and the recent advancement of SER-270 for tardive dyskinesia, we are demonstrating how the POZ Platform can enable differentiated, long-acting therapies across neurological conditions with high unmet need,” said Steve Ledger, CEO of Serina Therapeutics. “We believe our proprietary polymer technology can unlock best-in-class treatment profiles and improve patient outcomes in ways not achievable with existing drug delivery approaches." Advancement of SER-270 for Tardive Dyskinesia: In July 2025, Serina announced the advancement of SER-270 (POZ-VMAT2i), a once-weekly injectable therapy for tardive dyskinesia (TD), enabled by the POZ Platform. The program aims to address unment needs in TD treatment, particularly for institutional use and adherence challenges. SER-270 may also be evaluated for Huntington's disease chorea, a high need indication with limited long-acting injectable (LAI) options.Board Appointments: In May 2025, Serina appointed Stephen (Steve) Brannan, M.D. to its Board of Directors. Mr. Brannan brings more than three decades of experience in neuroscience and neuropsychiatry drug development, with a proven track record of leading clinical programs from early development through regulatory approval and commercialization. Dr. Brannan held senior leadership roles at Takeda, Novartis, Cyberonics (now LivaNova), and Eli Lilly, focusing on clinical programs for depression, Alzheimer's, schizophrenia, and epilepsy. Most recently, as Chief Medical Officer at Karuna Therapeutics, he led the clinical strategy for KarXT (xanomeline–trospium), the first new schizophrenia treatment in over 30 years, which was key in Karuna’s $14 billion acquisition by Bristol Myers Squibb in 2024. This addition strengthens Serina’s Board as the company advances its innovative therapeutic pipeline toward the clinic.$5 Million in Funding: In April 2025, Serina secured $5 million from strategic shareholders to support the continued development of SER-252 (POZ-apomorphine), Serina's lead clinical candidate for Advanced Parkinson's disease, as the company prepares to initiate a Phase 1 clinical trial in the fourth quarter of 2025.Financing via ATM: In April 2025, Serina entered into a Capital on Demand™ Sales Agreement with JonesTrading Institutional Services LLC with respect to an at the market offering program under which the Company may offer and sell $13.3 million of shares of Serina common stock in "at-the-market" (ATM) offerings. As of August 8, 2025, Serina issued 199,562 shares of common stock at a gross average price of $5.95, resulting in net proceeds of $1.2 million. Second Quarter Operating Results Revenues: Revenues were $130 thousand for three months ended June 30, 2025, compared to $51 thousand for the same period in 2024. Revenues were comprised entirely of grant revenues from the National Institutes of Health. Operating expenses: Operating expenses for the three months ended June 30, 2025 and 2024 were $5.7 million and $3.9 million, respectively. Research and Development (R&D) Expenses: R&D expenses were $3.2 million for the three months ended June 30, 2025, compared to $1.6 million for the same period in 2024. The increase of $1.6 million is primarily driven by increases in outside research services, consultant spend for research programs and a increase in salaries, payroll related expenses and stock based compensation as a result of increased headcount. These increases were partially offset by decreases in professional fees for the maintenance of certain patent and other intellectual property and biological material assets included in Legacy Assets and severance related costs. General and Administrative Expenses: General and administrative expenses were $2.5 million for the three months ended June 30, 2025, compared to $2.3 million for the same period in 2024. The increase of $0.2 million is due primarily to increases of stock based compensation expenses as a result new option grants, and financial consulting expenses primarily due to the deployment of new platforms and software. These increases were partially offset by a decrease in legal fees primarily as the result of the conclusion of our post-merger compliance and reporting activities. Other (Expense) Income, Net: Other expense, net was $0.9 million for the three months ended June 30, 2025 compared to $9.0 million net income for the same period in 2024. The $9.9 million increase in expenses was primarily attributable $10.3 million change in fair value of liability classified warrants, offset by the decrease of $0.3 million in interest expense. Net (Loss) Income: The net loss attributable to Serina for the three months ended June 30, 2025 was $6.4 million, or $(0.66) per basic and diluted share, compared to net income of $5.2 million, or $0.61 per basic share and $0.51 per diluted share for 2024. Liquidity Information Cash and cash equivalents totaled $6.0 million as of June 30, 2025. The Company projects its cash and cash equivalents as of June 30, 2025 to fund operations into the fourth quarter of 2025. About Serina Therapeutics Serina is a clinical-stage biotechnology company developing a pipeline of wholly owned drug product candidates to treat neurological diseases and other indications. Serina’s POZ Platform™ provides the potential to improve the integrated efficacy and safety profile of multiple modalities including small molecules, RNA-based therapeutics and antibody-based drug conjugates (ADCs). Serina is headquartered in Huntsville, Alabama on the campus of the HudsonAlpha Institute of Biotechnology. About the POZ Platform™ Serina’s proprietary POZ technology is based on a synthetic, water soluble, low viscosity polymer called poly(2-oxazoline). Serina’s POZ technology is engineered to provide greater control in drug loading and more precision in the rate of release of attached drugs delivered via subcutaneous injection. The therapeutic agents in Serina’s product candidates are typically well-understood and marketed drugs that are effective but are limited by pharmacokinetic profiles that can include toxicity, side effects and short half-life. Serina believes that by using POZ technology, drugs with narrow therapeutic windows can be designed to maintain more desirable and stable levels in the blood. Serina’s POZ platform delivery technology has potential for use across a broad range of payloads and indications. Serina intends to advance additional applications of the POZ platform via out-licensing, co-development, or other partnership arrangements, including the non-exclusive license agreement with Pfizer, Inc. to use Serina’s POZ polymer technology for use in lipid nanoparticle drug (LNP) delivery formulations. About SER-252 (POZ-apomorphine) SER 252 is an investigational apomorphine therapy developed with Serina’s POZ platform and designed to provide continuous dopaminergic stimulation (CDS). CDS has been shown to reduce the severity of levodopa-related motor complications (dyskinesia) in Parkinson’s disease. Preclinical studies support the potential of SER 252 to provide CDS without skin reactions. Serina plans to advance SER 252 to clinical testing in 2025. About SER-270 (POZ-VMAT2i) SER-270 is an investigational once-weekly VMAT2 inhibitor developed with Serina’s POZ platform to address adherence and access challenges in tardive dyskinesia (TD). TD is a disabling movement disorder often caused by long-term exposure to antipsychotic medications. The subcutaneous formulation of SER-270 is designed for patients on long-acting injectable antipsychotics, those with dysphagia, and institutionalized populations and other patients with challenged adherence. Serina is also exploring development in Huntington’s disease chorea. For more information, please visit https://serinatherapeutics.com.
