Abstract:
Effacement of horizontal forehead lines (FHL) with onabotulinumtoxinA has not been investigated in prospective Phase 3 studies. OBJECTIVE To evaluate safety and efficacy of onabotulinumtoxinA treatment of FHL together with glabellar lines (GL). MATERIALS AND METHODS A 12-month, Phase 3 study randomized subjects with moderate-to-severe FHL and GL to onabotulinumtoxinA 40 U or placebo, distributed between the frontalis (20 U) and glabellar complex (20 U). After Day 180, subjects could receive up to 2 additional open-label onabotulinumtoxinA treatments. Efficacy was assessed using the Facial Wrinkle Scale (FWS) and Facial Line Outcomes questionnaire. RESULTS The intent-to-treat (ITT) population included 391 subjects, and the modified ITT (mITT) population (subjects with psychological impact) included 254 subjects. After 30 days, onabotulinumtoxinA significantly improved the investigator- and subject-assessed appearance of FHL severity by at least 2 FWS grades in 61.4% of ITT subjects versus 0% of placebo subjects ( p 〈 .0001). In the mITT population, 94.8% of onabotulinumtoxinA subjects and 1.7% of placebo subjects achieved investigator- and subject-assessed FWS ratings of none/mild ( p = .0003). Patient-reported outcomes were consistent with FWS ratings. OnabotulinumtoxinA was well tolerated. CONCLUSION OnabotulinumtoxinA 40 U distributed between the frontalis and glabellar complex was safe and effective for treatment of moderate-to-severe FHL.
