Trial Outcomes & Findings for Study to Investigate the Safety and Duration of Effect of Different Botulinum Toxin A (NT 201) Dose Groups Following the Treatment of Glabellar Frown Lines (NCT NCT03806933)

NCT ID: NCT03806933

Last Updated: 2023-11-15

Results Overview

Duration of effect: time between treatment and first occurrence of relapse to baseline status. If no effect was observed, duration of effect was set to 0. Effect: any improvement (at least 1 point) at maximum frown as assessed by investigator on FWS. Investigator's FWS assessed status of GFL according to 4-point severity grades at maximum frown as: 0 (none), 1 (mild), 2 (moderate), 3 (severe). Descriptors of each severity grade for investigator's FWS assessment at maximum frown were as: 0 (no muscle action at all), 1 (some even slight muscle action possible \[that is, visible furrows\]), 2 (moderately strong muscle action possible \[that is, visible muscle bulges\]), 3 (strong muscle action possible which may cause local pallor). Duration of effect was analyzed using Kaplan-meier analysis, and 95 percent (%) confidence interval (CI) were calculated using log-log transformation.

Participant Flow

Study was conducted at 9 sites in Germany and the United States from 23 January 2019 to 8 October 2020. Out of 256 participants, 15 participants were screen failures and 241 participants were enrolled and randomized in the study. Study had 2 periods: Main Period (MP) and an optional Open-label Extension (OLEX) Period. As planned, combined safety data for MP and OLEX Period was reported.

In MP, Stage 1, participants received NT 201: 20 unit (U), 50 U or 75 U. Based on safety data of Stage 1, Stage 2 was started, and participants received NT 201 20 U or 100 U. After completion of MP, participants had the opportunity to receive an optional follow-up treatment with NT 201 20 U in OLEX period. As planned, 20 U group data from Stages 1 and 2 were pooled.

SECONDARY outcome

Timeframe: From the time of first treatment up to Day 360

Population: The FAS was subset of participants exposed to study medication for whom any efficacy variable was available.

Duration of effect was defined as time between treatment and first point in time when score was moderate or severe again. If no effect was observed, duration of effect was set to 0. Effect was defined by a score of none (0) or mild (1) at maximum frown as assessed by investigator according to FWS. Investigator's FWS assessed status of GFL according to 4-point severity grades at maximum frown as: 0 (none), 1 (mild), 2 (moderate), 3 (severe). Descriptors of each severity grade for investigator's FWS assessment at maximum frown were as: 0 (no muscle action at all), 1 (some even slight muscle action possible \[that is, visible furrows\]), 2 (moderately strong muscle action possible \[that is, visible muscle bulges\]), 3 (strong muscle action possible which may cause local pallor). Duration of effect was analyzed using Kaplan-meier analysis, and 95% CI were calculated using log-log transformation.

Duration of effect: time between treatment and first point in time when improvement was less than 2 points again. If no effect was observed, duration of effect was set to 0.
