Phase 3
Completed
Conditions
Post-stroke spasticity of the upper-limb
Registration Number
JPRN-jRCT2080222976
Lead Sponsor
Merz Pharmaceuticals GmbH
Brief Summary

The study confirmed efficacy of NT 201 for upper limb spasticity. Both high (400 U) and low (250 U) doses of NT 201 significantly improved the poststroke spasticity of upper limb as measured using AUC of changes in MAS score after a single injection over a period of 12 weeks. The study also confirmed the favorable safety and tolerability profile of NT 201 400 U in spasticity patients. No new or unexpected safety concerns were identified.
