Een studie ter evaluatie van de werkzaamheid en veiligheid van SM04554-topische oplossing bij mannelijke proefpersonen met androgenetische alopecia

9 september 2026 bijgewerkt door: Biosplice Therapeutics, Inc.

Multicenter, gerandomiseerde, dubbelblinde, placebogecontroleerde studie van de werkzaamheid en veiligheid van 0,15% en 0,25% concentraties van actuele SM04554-oplossing bij mannelijke proefpersonen met androgenetische alopecia

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.

Studie Overzicht

Gedetailleerde beschrijving

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
Tijdsspanne: 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.

Improvement in Subject Assessment of Hair Growth
Tijdsspanne: Weeks 6, 12, 18, 24, 30, 36, 42 and 48

Subjects will complete a questionnaire for hair growth while referencing the global scalp photograph taken at the visit as compared to their baseline global scalp photograph. The scale for the questionnaire ranges from -3 to +3 (-3 indicates the worst outcome and +3 indicates the best outcome). Improvement is defined as +1, +2, and +3: Much Better.
