BACKGROUND: DaxibotulinumtoxinA for Injection (DAXI) is a novel botulinum toxin type A formulation approved for the treatment of glabellar lines. The efficacy, safety, and extended duration of response of DAXI 40 U for glabellar lines were demonstrated in 2 Phase 3, randomized, double-blind studies (SAKURA 1 and 2) and a Phase 3 open-label trial (SAKURA 3).
OBJECTIVES: The aim of this study was to evaluate the efficacy and safety of the first DAXI 40 U treatment received in SAKURA 1, 2, or 3 across age and race subgroups.
METHODS: Adults with moderate-to-severe glabellar lines (Investigator Global Assessment-Frown Wrinkle Severity [IGA-FWS] and Patient FWS [PFWS] scales) were evaluated for glabellar line severity for ≤36 weeks after the first DAXI treatment. Efficacy and safety were analyzed by age (18-45, >45-55, and >55 years) and race (Asian, Black and African American, and White).
RESULTS: Overall, 2785 patients were included in the efficacy analysis. The proportion of patients achieving none or mild glabellar line severity at maximum frown (IGA-FWS) after DAXI treatment was high in all age and race subgroups (>96% at Week 4). Glabellar line severity of none or mild by composite IGA-FWS and PFWS rating was maintained for a median of 24.0 weeks in all age subgroups, and for 27.0, 25.3, and 24.0 weeks in the Asian, Black and African American, and White subgroups, respectively. Treatment-emergent adverse events were similar across all subgroups.
CONCLUSIONS: Consistent with the overall study population, DAXI 40 U demonstrated a high response rate and duration of effect of ≥24 weeks across all age and race subgroups.
