Safety and Efficacy Study of the Simultaneous Treatment of Upper Facial Lines (Horizontal Forehead Lines, Glabellar Frown Lines and Lateral Canthal Lines) in Subjects With Moderate to Severe Upper Facial Lines

Merz North America, Inc.362 enrolled

Overview

The purpose of this study is to investigate the safety and efficacy of NT 201 (active ingredient: Botulinum (neuro)toxin type A, free from complexing proteins) in the combined treatment of wrinkles in the upper face (Upper Facial Lines \[UFL\]): Horizontal Forehead Lines \[HFL\], Glabellar Frown Lines \[GFL\], and Lateral Canthal Lines \[LCL\]). It is a prospective, randomized, double-blind, placebo-controlled, multicenter study with a placebo-control main period (MP) followed by an open-label extension (OLEX) period.

Outcomes

Primary Outcomes

Main Period: Percentage of Glabellar Frown Line (GFL) Responders at Day 30

The Merz aesthetics scales (MAS) are 5-point scales used to identify responders in a clinical context. They are validated photograph-based outcome instruments designed specifically for assessment of each upper facial area. GFL-response was defined as a score of 0 (no) or 1 (mild) and at least two-grade improvement from baseline to Day 30 of main period on MAS for GFL at maximum contraction as assessed by both the investigator and the subject. The MAS for GFL ranged as 0 to 4 where 0 is "No glabellar lines", 1 is "Mild glabellar lines", 2 is "Moderate glabellar lines", 3 is "Severe glabellar lines" and 4 is "Very severe glabellar lines".

Main Period: Number of Subjects With Related Treatment-Emergent Adverse Events (TEAEs)

TEAEs during the Main Period are defined as adverse events (AEs) with onset or worsening on or after date and time of first dose of study treatment and before date and time of first administration of study treatment in the OLEX period or the final study visit, if subject was not treated in the OLEX period. An AE is considered to be related if a causal relationship between study treatment and the AE is at least reasonably possible.

Time frame: Up to 22 Weeks

TEAEs of the OLEX period are defined as AEs with onset or worsening on or after date and time of first dose of study treatment in the OLEX period up to and including the final study visit. An AE is considered to be related if a causal relationship between study treatment and the AE is at least reasonably possible.

Time frame: Up to 39 Weeks
