A Global Study to Assess the Drug Dynamics, Efficacy, and Safety of Venglustat (GZ/SAR402671) in Parkinson's Disease Patients Carrying a Glucocerebrosidase (GBA) Gene Mutation — MOVES-PD  

Parkinson's Disease Clinical Trial

Official title: Multicenter, Randomized, Double-blind, Placebo Controlled Study to Assess the Efficacy, Safety, Pharmacokinetics, and Pharmacodynamics of GZ/SAR402671 in Patients With Early-stage Parkinson's Disease Carrying a GBA Mutation or Other Pre-specified Variant

Status Terminated

Clinical Trial Summary

Primary Objectives:

• Part 1: To determine the safety and tolerability of 4, 8, and 15 milligrams of GZ/SAR402671 (venglustat) administered orally for 4 weeks, as compared to placebo in participants with early-stage Parkinson's disease (PD) carrying a glucocerebrosidase gene (GBA) mutation or other pre-specified variants.

• Part 2: To determine the efficacy of GZ/SAR402671 administered orally daily, as compared to placebo in participants with early-stage PD carrying a GBA mutation or other pre-specified variants.

Secondary Objectives:

Part 1:

• To assess the pharmacokinetic (PK) profile of oral dosing of GZ/SAR402671 in plasma when administered in early-stage PD participants carrying a GBA mutation.

• To assess the exposure of GZ/SAR402671 in cerebrospinal fluid (CSF) when administered in early-stage PD participants carrying a GBA mutation.

Part 2:

• To demonstrate overall safety and tolerability of GZ/SAR402671 administered orally for 52 weeks in early-stage PD participants carrying a GBA mutation as compared to placebo.

• To assess the pharmacodynamic response to daily oral dosing of GZ/SAR402671 in plasma and CSF as measured by glucosylceramide (GL-1) when administered in early-stage PD participants carrying a GBA mutation over a 52-week period.

Clinical Trial Description

Part 1: the total duration was as following:

i) Rest of the world (ROW): up to approximately 50 weeks (8.5 weeks of screening, maximum of 36 weeks of treatment and 6 weeks follow-up).

ii) Japan only: up to approximately 66 weeks (8.5 weeks of screening, maximum of 52 weeks of treatment and 6 weeks follow-up).

Part 2: the total duration was up to approximately 224 weeks that consisted of 8.5 weeks of screening period, 52 weeks of treatment period, 156 weeks of long-term follow-up (LTFU) period and 8 weeks of post-treatment period.

At the end of a 52-week main placebo-controlled treatment period, all participants were evaluated for possibility to transition to receive active treatment for 156 weeks plus 8-week post-treatment observation. ;
