Phase I/III Clinical Trial to Evaluate the Safety and Efficacy of a New Botulinum Toxin (HU-014) Versus OnabotulinumtoxinA in Subjects With Moderate-to-Severe Crow's Feet Lines

초록

BACKGROUND: HU-014, a newly introduced botulinum toxin type A, has not been investigated for its efficacy and safety in crow's feet line (CFL) treatment. OBJECTIVE: Here, we compared the efficacy and safety of HU-014 and onabotulinumtoxinA in CFL treatment. METHODS: This was a randomized, double-blind, active drug-controlled, multicenter, 16-week, Phase I/III study designed to determine the noninferiority of HU-014 compared with onabotulinumtoxinA in moderate-to-severe CFL treatment. In the Phase III study, 290 subjects were randomized at a 1:1 ratio to receive a single treatment of HU-014 or onabotulinumtoxinA. The primary endpoint was the proportion of subjects achieving Grade 0 or 1 in the facial wrinkle scale on maximum smile at Week 4. RESULTS: The primary endpoint was achieved by 72% of the subjects with HU-014 and onabotulinumtoxinA treatments, supporting the noninferiority of HU-014 compared with onabotulinumtoxinA. All secondary efficacy outcomes were achieved by the subjects. The 2 groups showed no significant differences in the safety analysis. CONCLUSION: HU-014 has noninferior efficacy and safety compared with onabotulinumtoxinA in the treatment of CFL. Copyright © 2020 by the American Society for Dermatologic Surgery, Inc.
