Une étude évaluant l'efficacité et l'innocuité de la solution topique SM04554 chez des sujets masculins atteints d'alopécie androgénétique

9 septembre 2026 mis à jour par: Biosplice Therapeutics, Inc.

Étude multicentrique, randomisée, en double aveugle et contrôlée par placebo sur l'efficacité et l'innocuité des concentrations de 0,15 % et 0,25 % de la solution topique SM04554 chez des sujets masculins atteints d'alopécie androgénétique

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.

Aperçu de l'étude

Description détaillée

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.

Délai
Absolute Non-vellus Hair Count in Target Area
Délai: 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.
