Clinical trials

This is a first-in-human (FIH) study of orally administered VT-5006 (also known as AX-5006) in healthy adult volunteers (HVs) and adult participants with Parkinson's disease (PD). The goal of this clinical trial is to learn if VT-5006 is safe and tolerable in healthy volunteers and in participants with PD. It has three Parts (A, B, and C). Part A: Healthy volunteers aged 18-54 will attend a screening visit, take a single dose of VT-5006 or matching placebo after an overnight fast, stay in the clinic for three nights, and complete a follow-up visit. One group of participants in Part A will be asked to return to the clinic after approximately two weeks, take a single dose of VT-5006 or matching placebo after consuming a high-fat meal and stay in the clinic for another three nights. Part B: Healthy volunteers aged 18-54 will attend a screening visit, take one dose of VT-5006 or matching placebo each day for seven days after fasting overnight, stay in the clinic for 10 nights, and complete a follow up visit. Part C: Participants with PD aged 40-80 will attend a screening visit, take one dose of VT-5006 (high dose), VT-5006 (low dose), or matching placebo each day for 28 days, complete two overnight stays in the clinic, attend three clinic visits, one phone call and a follow up visit.

This study seeks to understand the prevalence and variability of a gut bacteria gene called csgA in people with Parkinson's Disease. This understanding could inform development of potential new therapies targeting the gut in Parkinson's Disease.
