Positive Results from Phase III, Split-Face, Head-to-Head Study Comparing OnabotulinumtoxinA and PrabotulinumtoxinA in the Treatment of Crow’s Feet Lines Published in Dermatologic Surgery
The Phase III multicenter, randomized, double-blind, active-controlled, split-face study was conducted in Korea. The study evaluated the efficacy and safety of prabotulinumtoxinA1 and onabotulinumtoxinA in the treatment of subjects with bilateral symmetric, moderate to severe crow's feet at maximum smile. A total of 204 subjects were randomized across three medical centers. The primary efficacy outcome was the proportion of subjects with Grade 0 or 1 severity of crow’s feet at maximum smile at Week 4 as assessed by the investigators using a facial wrinkle scale. The primary endpoint of non-inferiority was achieved with responder rates* of 65.02% for prabotulinumtoxinA and 62.56% for onabotulinumtoxinA at Week 4. There were no serious adverse events assessed as drug-related across these studies, and the adverse event rate for the prabotulinumtoxinA and onabotulinumtoxinA arms of the study were similar. Of 204 subjects in the safety analysis set, 22 (10.8%) reported 30 adverse events. All adverse events were mild (11 cases) or moderate (19 cases) in severity.
“The results of this head-to-head Phase 3 study comparing prabotulinumtoxinA and onabotulinumtoxinA in the treatment of crow’s feet add important new clinical information to the already robust data set surrounding prabotulinumtoxinA,” said
