In Brief

A Phase 2 clinical trial evaluating Placebo and Suvecaltamide for Parkinson Disease and Tremor. Completed, enrolled 169 participants across 37 sites in 4 countries.

Detailed Summary

This is a 17-week double-blind, placebo-controlled, randomized, flexible-dosing, parallel-group, multicenter study designed to evaluate the efficacy and safety of suvecaltamide for the treatment of moderate to severe residual tremor in adult participants with Parkinson's disease (PD). The target population represents participants who have tremor that is not adequately controlled by PD medications and that interferes with their activities of daily living (ADL) and/or with their performance of tasks.
