Brief summary

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 was to evaluate the safety and efficacy of AGN-151586 for the treatment of GL in participants with moderate to severe GL. This was a 12-week study in which eligible subjects were enrolled into the study containing 2 treatment periods, double-blind period and open-label period. Participants were randomly assigned to receive AGN-151586 or placebo. There was 1 in a 4 chance that participants would receive placebo. Around 600 adult participants with moderate to severe GL were to be enrolled in the study in approximately 38 sites across the world. Participants received either AGN-151586 or Placebo administered as 5 intramuscular injections to the glabellar complex on Day 1. Participants meeting retreatment criteria may have received an open-label treatment of AGN-151586 during the study. Participants attended regular visits during the study at a study site. The effect of the treatment was checked by medical assessments, blood tests, telephone calls, questionnaires and checking for side effects.

Number of Participants With Adverse Events

An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of study drug. A serious adverse event (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgment, may jeopardize the participant and may require medical or surgical intervention to prevent any of the outcomes listed above.

Time frame: From time of informed consent to end of study; median time on follow-up was 85 days for Double-blind Placebo, AGN-151586, Open-label Placebo/AGN-151586 and AGN-151586/AGN-151586 groups, 50 days for Placebo/None group, and 53 days for AGN-151586/None group

Population: Safety population: all participants who were treated with at least 1 dose of study drug. All safety analyses were performed with participants analyzed by their actual treatment received in the DB period/OL period.

\[Primary endpoint for European Union regulatory agencies\] Percentage of participants with a ≥ 2-grade improvement from Baseline on the Facial Wrinkle Scale (FWS) according to investigator assessment 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.

Time frame: Baseline, Day 7 (Double-blind Period)

Population: Intent-to-Treat (ITT) Population: all randomized participants, analyzed according to the treatment groups to which they were randomized, with a Baseline Facial Lines Outcome (FLO-11) total score (transformed) of ≤50. Multiple imputation was used for missing data.

Time to Return to Baseline FWS According to Investigator Assessment of FWS at Maximum Frown After Achieving Responder Definition on Day 7 [European Union Regulatory Agencies]

\[Secondary endpoint for European Union regulatory agencies\] Time to return to Baseline (Baseline criterion of Moderate or Severe) on the Facial Wrinkle Scale (FWS) according to investigator assessment of FWS at maximum frown after achieving responder definition on Day 7 is reported. Responder definition was a rating of None or Mild on the FWS. 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. For those who maintained their response, censoring occurred at the latest visit during the treatment period for which FWS was available.

Time frame: From Baseline to Day 43 (Double-blind Period)

Population: Intent-to-Treat (ITT) Population: all randomized participants, analyzed according to the treatment groups to which they were randomized with a Baseline Facial Lines Outcome (FLO-11) total score (transformed) of ≤50. Participants who did not meet the responder definition on Day 7 were excluded from the analysis; analysis was limited to those that responded.
