Conditions

Facial Rhytides, Glabellar Frown Lines

Brief summary

This study evaluated the safety and efficacy of botulinum toxin Type A compared to placebo for the treatment of forehead lines (facial rhytides) when also administered to frown lines (glabellar rhytides).

Interventions

BIOLOGICALbotulinum toxin Type A

Botulinum toxin Type A (total dose 30 Units or 40 Units) injected into bilateral forehead and frown line areas on Day 1.

DRUGNormal Saline

Normal Saline (placebo) injected into bilateral forehead and frown line areas on Day 1.

Design outcomes

Primary

MeasureTime frameDescription
Percentage of Participants Achieving a Score of None or Mild by Investigator-Assessed Facial Wrinkle Scale With Photonumeric Guide (FWS) in Forehead Lines at Maximum Eyebrow ElevationDay 30The Investigator assessed the severity of the patient's forehead lines at maximum eyebrow elevation using the 4-point FWS: 0=none, 1=mild, 2=moderate or 3=severe. The percentage of participants with a score of none or mild at Day 30.
Percentage of Participants Achieving a Score of None or Mild by Subject-Assessed Facial Wrinkle Scale With Photonumeric Guide (FWS) in Forehead Lines at Maximum Eyebrow ElevationDay 30The patient assessed the severity of their forehead lines at maximum eyebrow elevation using the 4-point FWS: 0=none, 1=mild, 2=moderate or 3=severe. The percentage of participants with a score of none or mild at Day 30.

Secondary

MeasureTime frameDescription
Percentage of Participants Achieving Satisfied or Very Satisfied by Subject Assessment of Satisfaction of Appearance of Forehead LinesDay 30Participants rated their overall satisfaction with the appearance of the forehead line area using a 5-point scale: 1=very unsatisfied, 2=unsatisfied, 3=neutral, 4=satisfied or 5=very satisfied. The percentage of participants with a rating of satisfied or very satisfied at Day 30.
Percentage of Participants With a ≥1 Grade Improvement From Baseline by Investigator-Assessed FWS in Forehead Lines at RestBaseline, Day 30The Investigator assessed the severity of the patient's forehead lines at rest using the 4-point FWS: 0=none, 1=mild, 2=moderate or 3=severe. The percentage of participants with a ≥1 grade improvement from baseline.
