In Brief

A Phase 2 clinical trial evaluating NT 201 and Placebo for Essential Tremor of the Upper Limb. Completed, enrolled 78 participants across 14 sites in 3 countries.

Detailed Summary

The purpose of this study is to determine whether a single treatment with NT 201 (botulinum toxin) is superior to placebo (no medicine) for one-sided treatment of essential tremor in the motor-dominant arm (Unilateral Period). Participants will be assigned to the treatment groups by chance and neither the participants nor the research staff who interact with them will know the allocation. The following treatment cycle will investigate the safety and tolerability of two-sided treatment with NT 201 (botulinum toxin) (Open Label Bilateral Period). All participants will receive NT 201 treatment.
