San Diego, December 16, 2025
Aspen Neuroscience has announced a pivotal Phase 3 clinical trial for ANPD001, a personalized cell therapy aimed at treating moderate to advanced Parkinson’s disease. Following the promising results of the Phase 1/2a ASPIRO study, this upcoming trial, set to begin in early 2026, seeks to further evaluate the therapy’s safety and efficacy. The company has recently secured $115 million in funding to support this initiative, which could transform Parkinson’s management through innovative regenerative therapy utilizing patients’ own cells.
Aspen Neuroscience Advances Parkinson’s Disease Treatment with Phase 3 Trials
San Diego, CA – Aspen Neuroscience, a clinical-stage biotechnology company specializing in autologous regenerative therapies, has announced plans to initiate a pivotal Phase 3 clinical trial for its lead program, ANPD001, in early 2026. This trial aims to evaluate the safety and efficacy of ANPD001, a personalized cell therapy designed to treat moderate to advanced Parkinson’s disease (PD).
Details of the Upcoming Phase 3 Trial
The forthcoming Phase 3 trial will build upon the foundation established by the earlier Phase 1/2a ASPIRO study. This earlier study demonstrated that ANPD001 was well-tolerated among participants, with no major safety concerns reported. Additionally, patients exhibited early improvements in both patient-reported and clinician-reported outcomes, indicating the potential transformative impact of this therapy on PD management.
Recent Developments and Financial Support
In November 2025, Aspen Neuroscience secured $115 million in a Series C financing round, co-led by OrbiMed, ARCH Venture Partners, Frazier Life Sciences, and Revelation Partners. This substantial investment is intended to accelerate the clinical development of ANPD001 and support the scaling of manufacturing processes to meet both clinical and commercial demands. Notably, Kite, a Gilead Company, participated in this funding round, underscoring the growing interest in personalized cell therapies for neurodegenerative diseases.
Background on ANPD001 and Its Development
ANPD001 is an autologous dopaminergic neuronal precursor cell therapy developed by Aspen Neuroscience. The therapy involves reprogramming a patient’s own skin cells into dopaminergic neuron precursors, which are then transplanted into the brain to replace lost dopamine-producing neurons—a hallmark of Parkinson’s disease. This personalized approach aims to address the underlying causes of PD, potentially offering a more effective and tailored treatment option for patients.
The upcoming Phase 3 trial represents a critical step in Aspen Neuroscience’s commitment to advancing innovative treatments for Parkinson’s disease, with the goal of improving patient outcomes and quality of life.
