Insights

Biotech Financial Analyst

Serina Therapeutics' 2024 financials reveal concerning fundamentals with only $56,000 in revenue (down 98% from $3.2M in 2023), widening losses of $11.1M (versus $5.3M profit in 2023), and rapidly growing expenses ($17.1M vs $6.3M in 2023). The cash position of $3.7M plus January's $5M investment only provides runway through Q2 2025 - a critically short timeframe for clinical development.

The sale of UniverXome eliminated $11.2M in debt, significantly strengthening the balance sheet, but hasn't solved the cash burn problem. The $10M financing from JuvVentures provides essential capital for advancing SER-252 to Phase 1 trials for Parkinson's disease, though more funding will be needed soon.

While R&D expenses increased 213% to $7.5M, mainly directed toward SER-252 development, G&A expenses soared 146% to $9.6M - an inefficient ratio for a clinical-stage biotech. Strategic partnerships like the Enable Injections collaboration for wearable delivery represent potential value creation, but the immediate financial picture indicates significant operational inefficiency with questionable resource allocation.

Pharmaceutical Development Specialist

Serina's POZ Platform technology advancement represents a potentially valuable approach for drug optimization, with their lead candidate SER-252 (POZ-apomorphine) for advanced Parkinson's disease progressing toward Phase 1b trials in Q4. The partnership with Enable Injections merits attention as it could address a critical delivery challenge in Parkinson's treatment.

The integration of Serina's polymer technology with Enable's enFuse wearable platform addresses the significant unmet need for continuous dopaminergic stimulation without the complications of traditional delivery methods. Current apomorphine delivery systems are by inconsistent absorption and challenging administration, making this potential advancement clinically significant.

However, early-stage clinical development carries substantial execution risk. While the $10M financing supports near-term clinical goals, the runway only extends through Q2 2025, creating timeline pressure. The sale of UniverXome indicates portfolio prioritization but raises questions about the commercial viability assessment of their other assets. The company's strategic focus on neurological applications is sensible, though the mentioned expansion into RNA and ADC therapeutics suggests potential resource dilution at a critical development stage.

HUNTSVILLE, March 24, 2025 (GLOBE NEWSWIRE) -- Serina Therapeutics, Inc. (“Serina”) (NYSE American: SER), a clinical-stage biotechnology company developing its proprietary POZ Platform^™ drug optimization technology, today reported its financial results for the full year ended December 31, 2024 and provided recent business highlights.

"We are encouraged by the progress we’ve made this year. Our partnership with Enable Injections’ wearable technology, combined with our POZ optimization technology, is poised to deliver a differentiated product profile and potential best-in-class therapy for advanced Parkinson’s patient care. We are on track towards our goal of dosing the first patient in a Phase 1b clinical trial in the fourth quarter,” said Steve Ledger, CEO of Serina Therapeutics. "We also continue to advance our POZ Platform^™ in addressing complex neurological needs and remain committed to pushing the boundaries of the platform’s potential in RNA and ADC therapeutics innovation to improve patient outcomes and quality of life."

Recent Highlights

• $10 Million Financing: In November 2024, Serina secured a $10 million equity financing from strategic shareholder JuvVentures (UK) Limited.

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.
