PrabotulinumtoxinA for Treatment of Millennials With Moderate to Severe Glabellar Lines: Post Hoc Analyses of the Phase III Clinical Study Data.

BACKGROUND

The use of esthetic products by millennials is increasing, yet published clinical trial data in this population are limited.

OBJECTIVE

To compare the efficacy and safety of prabotulinumtoxinA for the treatment of moderate to severe glabellar lines in millennial and nonmillennial patients.

METHODS AND MATERIALS: Post hoc analyses were performed on the pooled population of all patients treated with 20U prabotulinumtoxinA in the 3 single-dose Phase III glabellar line clinical studies. Patients were grouped by age: millennials (born 1982-2000) versus nonmillennials (born ≤1981). One key efficacy end point was the proportion of responders with a ≥1-point improvement from baseline at maximum frown on the 4-point Glabellar Line Scale. Adverse events were also summarized.

RESULTS

Responder rates among millennials (n = 65) were greater than those of nonmillennials (n = 668) by 7.7% on average across all visits; differences were statistically significant at Day 90. Responder rates at Day 90 were 90.2% and 76.1%, respectively (absolute difference of 14.0%, p = .01). Headache was the most common treatment-related adverse event, occurring in 9.0% and 9.4% of millennials and nonmillennials, respectively.

CONCLUSION

A single dose of 20U prabotulinumtoxinA administered for the treatment of glabellar lines was similarly well-tolerated by both millennials and nonmillennials; overall, it was more efficacious in millennials.
