A Study to Assess Adverse Events and Change in Disease Activity of Intramuscular AGN-151586 Injection in Toxin-Naïve Adult Participants With Glabellar Lines

AbbVie309 enrolled

Overview

Facial lines that develop from repeated facial expression, such as glabellar lines (GL), are typically treated by selectively weakening specific muscles with small quantities of botulinum toxin. AGN-151586 is an investigational product being developed for the treatment of GL. The purpose of this study is to evaluate the safety and efficacy of AGN-151586 for the treatment of GL in toxin-naïve participants with moderate to severe GL. This is a 12 week study in which eligible subjects will be enrolled into the study containing 2 treatment periods, double-blind period and open-label period. Participants are randomly assigned to receive AGN-151586 or placebo. There is 1 in a 4 chance that participants will receive placebo. Around 300 adult participants with moderate to severe GL will be enrolled in the study in approximately 15 sites. Participants will receive either AGN-151586 or Placebo administered as 5 intramuscular injections to the glabellar complex on Day 1. Participants meeting retreatment criteria may receive an open-label treatment of AGN-151586 during the study. Participants will attend regular visits during the study at a study site. The effect of the treatment will be checked by medical assessments, blood tests, telephone calls, questionnaires and checking for side effects.

\[Primary endpoint for the United States FDA\] Percentage of participants achieving a Grade 0 or 1 (none or mild) and a ≥ 2-grade improvement from Baseline on the Facial Wrinkle Scale (FWS) according to both investigator and participant assessments of glabellar lines (GL) severity at maximum frown at Day 7 are reported. Assessments were performed using the 4-grade Facial Wrinkle Scale (FWS), where 0=none, 1=mild, 2=moderate, and 3=severe. Higher scores indicate more severity. Percentages are rounded off to nearest single decimal.

An adverse event (AE) is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with the treatment. The investigator assesses the relationship of each event to the use of study drug.

Time frame: From time of informed consent to end of study; median time on follow-up was 85 days for all groups.
