男性型脱毛症の男性被験者におけるSM04554局所溶液の有効性と安全性を評価する研究

2026年9月9日 更新者:Biosplice Therapeutics, Inc.

アンドロゲン性脱毛症の男性被験者における局所SM04554溶液の0.15%および0.25%濃度の有効性と安全性に関する多施設、無作為化、二重盲検、プラセボ対照研究

This multi-center, randomized, double-blind, placebo-controlled study, conducted in Turkey, will assess the efficacy and safety of topical SM04554 solution (0.15% and 0.25%) applied daily to the scalp of male androgenetic alopecia (AGA) subjects.

調査の概要

詳細な説明

This study was a multicenter, randomized, double-blind, placebo-controlled, parallel-group study conducted in Turkey of 2 different strengths of topical SM04554 solution applied QD to the scalp of male androgenetic alopecia (AGA) subjects - otherwise known as male pattern baldness.

Following a screening period of up to 2 weeks, subjects participated in the study for 54 weeks (48 weeks of treatment and 6 weeks of follow-up). Subjects were randomized into 1 of 3 groups in a 2:2:1 randomization scheme: SM04554 0.15% solution, SM04554 0.25% solution, and vehicle placebo.

Primary outcome of this study was change in absolute hair count as assessed by phototrichogram, a non-invasive and reproducible method to measure changes in hair.

Absolute Non-vellus Hair Count in Target Area
時間枠:Week 48

Non-vellus hair count was determined by phototrichogram. Standardized phototrichogram images of the treatment area were taken on Visit Day 1 (pre-treatment), as well as at visits occuring at Weeks 12, 24, 36, and 48. A rectangular area of the subject's hair with dimensions 20 x 15 mm was clipped to between 0.6 and 0.9 mm in length prior to performing the phototrichogram. Virtual tattoo technology was used to anchor the phototrichogram. Images were uploaded from sites to the blinded vendor where assessment of the phototrichogram took place.
