What this trial studies

This Phase 1/2 interventional trial implants RNDP-001 into the brain during a neurosurgical procedure to characterize safety and early signals of efficacy. Eligible participants are adults 45–75 with idiopathic Parkinson's disease who are medically stable for surgery and meet exclusion criteria such as known PD gene mutations or prior PD surgery. Primary outcomes emphasize safety and tolerability with structured post-operative monitoring, while secondary measures likely include clinical motor assessments and imaging follow-up. The study is conducted at three U.S. academic medical centers and requires in-person surgical and follow-up visits.

Who should consider this trial

Good fit: Ideal candidates are adults 45–75 with clinically diagnosed idiopathic Parkinson's disease who are medically fit for brain surgery and have not had prior Parkinson's infusion or surgical therapies.

Not a fit: People with known Parkinson's gene mutations, prior PD infusion or surgery, significant medical comorbidities, or MRI contraindications are unlikely to be eligible or to benefit from this intervention.

Why it matters

Potential benefit: If successful, RNDP-001 could become a new implantable treatment option that improves symptoms or slows disease progression for some people with Parkinson's disease.

How similar studies have performed: The RNDP-001 approach is relatively novel with limited direct human data, though other implantable therapies such as deep brain stimulation have a demonstrated history of clinical benefit in Parkinson's disease.
