Official title

Phase 3, Multicenter Open-label Extension Study to Evaluate the Safety of BOTOX (Botulinum Toxin Type A) Purified Neurotoxin Complex for the Treatment of Platysma Prominence

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is a Phase 3, open-label extension study to evaluate the long-term safety of repeat BOTOX treatments in adult participants with Platysma Prominence. Participants who completed the lead-in Phase 3 Study M21-309 and met eligibility requirements could enroll in this open-label extension study. Planned study enrollment was approximately 270 participants. Participants who met treatment criteria could receive up to 3 administrations of BOTOX. Day 1 (study entry) was the same day as Day 120/study exit visit of the lead-in Phase 3 study. The first administration of study drug could occur at the Day 1 visit, and the last administration of study drug could occur at the Day 180 visit (60 days prior to Day 240/study exit). Once a subject was enrolled in this study, monthly follow-up visits occurred.
