Abstract
Background: A once-daily minoxidil topical foam (MTF) has been developed to treat female pattern hair loss. Objective: Determine noninferiority of once-daily 5% MTF versus twice-daily 2% minoxidil topical solution (MTS) based on the change from baseline in target area hair count (TAHC) at 24 weeks. Methods: In a randomized, phase III trial, women with female pattern hair loss received once-daily 5% MTF (n=161) or twice-daily 2% MTS (n=161) for 52 weeks. Primary endpoint was change from baseline in TAHC at 24 weeks. Secondary endpoint was change from baseline in TAHC at 12 weeks. Exploratory endpoints included change in total unit area density and change in overall scalp coverage. Results: Once-daily 5% MTF increased TAHC from baseline (adjusted mean ± standard error) by 23.9 ± 2.1 hairs/cm2 at week 24. Twice-daily 2% MTS increased TAHC 24.2 ± 2.1 hairs/cm2 at week 24. The treatment difference was -0.3 hairs/cm2 (95% CI = -6.0, 5.4). Since the lower bound of the 95% CI was less than -5.0, the prespecified noninferiority goal was not met. Both treatments were well tolerated. Conclusions: Once-daily 5% MTF and twice-daily 2% MTS induced hair regrowth in female pattern hair loss, but prespecified noninferiority criteria were not met.
