Abstract
BACKGROUND:
An alternative to currently marketed topical minoxidil solutions is desirable.
OBJECTIVE:
To assess the efficacy and safety of a new 5% minoxidil topical formulation in a propylene glycol-free foam vehicle in men with androgenetic alopecia (AGA).
METHODS:
This was a 16-week, double-blind, placebo-controlled trial of 5% minoxidil topical foam (MTF) in 352 men, 18 to 49 years old. At week 16, 143 subjects continued on an open-label phase to collect 52 weeks of safety information on 5% MTF.
RESULTS:
At week 16 compared with baseline, there was a statistically significant increase in (1) hair counts in the 5% MTF group versus placebo (P < .0001) and (2) subjective assessment of improved hair loss condition (P < .0001) in the 5% MTF group versus placebo. The 5% MTF was well tolerated over a 52-week period.
LIMITATIONS:
There was no collection of efficacy data beyond 16 weeks.
CONCLUSIONS:
We believe that 5% MTF is a safe and effective treatment for men with AGA.
