OBJECTIVES:Compared with placebo, this phase I study evaluated the safety, tolerability, and pharmacokinetics of CG2001, a novel isopropyl alcohol-free minoxidil-finasteride combination topical foam, in Chinese males with androgenetic alopecia (AGA).
METHODS:In this randomized, double-blind, placebo-controlled trial, 44 subjects received single and multiple doses across five cohorts with varying finasteride concentrations (0.025%-0.1%) and frequencies. Safety, tolerability, and pharmacokinetics were evaluated. The concentrations of minoxidil-finasteride were both measured.
RESULTS:The result shows that CG2001 was safe and well-tolerated, with no serious adverse events. Systemic minoxidil exposure was consistent across most dosages, while finasteride exposure increased dose- and frequency-dependently, though it remained markedly lower than that reported with oral administration. Steady state was achieved for both drugs after 7 days.
CONCULSIONS:The favorable safety profile and reduced systemic finasteride exposure position CG2001 as a promising alternative, supporting further clinical development in a phase IIa trial, and provide a pharmacokinetic foundation for subsequent efficacy trials in patients with AGA.
