Investigational Oral Candidate JOTROL^™ Addresses a Parkinson's Disease Market with No Current Disease-modifying Therapies Available

Jupiter, FL, May 27, 2026 (GLOBE NEWSWIRE) -- Jupiter Neurosciences, Inc. (NASDAQ:JUNS), a clinical-stage biopharmaceutical company developing investigational therapies for neurodegenerative diseases, today announced that patient enrollment is now underway in its Phase 2a RESET clinical trial (NCT07592767) for JOTROL^™ (investigational trans-resveratrol micellar formulation) in Parkinson's Disease (PD), with first patient dosing expected in the near term.

Parkinson's Disease affects an estimated 1.1 million people in the United States, with roughly 90,000 new diagnoses annually, and carries an estimated annual U.S. economic burden of $82.2 billion. The global PD treatment market was valued at $5.65 billion in 2024 and is projected to reach $7.58 billion by 2030, growing at a CAGR of about 5.0%. Despite decades of research, no disease-modifying therapies have been approved for PD to date. JOTROL™ is an investigational drug candidate that has not been approved by the FDA or any regulatory authority. It is currently being evaluated for its potential to target underlying biological drivers of neurodegeneration.

"Despite advances in symptomatic management, there remains a significant unmet need for therapies that may address the underlying biological drivers of Parkinson's disease. We believe JOTROL^™'s enhanced CNS exposure and mechanistic profile position it as a potentially differentiated therapeutic candidate for neurodegenerative disorders characterized by oxidative stress, mitochondrial dysfunction and chronic neuroinflammation."

— Charbel Moussa, MBBS, PhD, Professor of Neurology and Director of the Translational Therapeutics Program, Georgetown University Medical Center; Coordinating Principal Investigator, RESET Study

"The global Parkinson's Disease treatment market — currently valued at $5.65 billion and growing at a 5.04% CAGR — represents a significant and expanding unmet need that Jupiter Neurosciences is working to address with JOTROL^™. With enrollment now underway in the Phase 2a RESET trial we have reached a critical operational milestone. We look forward to generating the clinical data needed to evaluate JOTROL^™'s potential and to serve patients, providers, and the broader scientific community."

— Christer Rosén, Chief Executive Officer, Jupiter Neurosciences, Inc. (NASDAQ:JUNS)

"The initiation of enrolment in the Phase 2a RESET trial marks the culmination of 10 years of research and development at Jupiter and is our largest clinical milestone to date. I echo the enthusiasm of my colleagues, thank all our collaborators contributing to this accomplishment and look forward to reporting out data as the trial progresses."

— Alison Silva, President & Chief Business Officer, Jupiter Neurosciences, Inc. (NASDAQ:JUNS)

Clinical Trial Details

Jupiter's RESET (RESvEraTrol in Parkinson's Disease) is active on www.clinicaltrials.gov, details here:

Study Details | NCT07592767 | RESvEraTrol in Parkinson's Disease (RESET) | ClinicalTrials.gov. The trial is a multi-center, randomized, double-blind, placebo-controlled Phase 2a study designed to evaluate the JOTROL^™ in Parkinson's Disease. In a well-established model of Parkinson's Disease JOTROL^™ demonstrated statistically significant neuroprotective effects including rotarod performance and grip strength, indicating preservation of motor function. These data supported the IND granted to the Company in November 2025. A summary of key milestones and observations:

Enrollment underway — Phase 2a RESET trial (NCT07592767) actively enrolling;
FDA IND Cleared — November 2025, enabling commencement of Phase 2a clinical evaluation (administrative clearance only; does not imply approvability)
~9-fold higher overall plasma bioavailability vs. conventional resveratrol (Cmax 455 ng/mL vs. 85 ng/mL in Phase 1, n=24 healthy volunteers) https://clinicaltrials.gov/study/NCT04668274
Measurable CSF drug levels observed in Phase 1, supporting CNS exposure
