About this study

Official title: Multicenter, Randomized, Double-Blind, Placebo-Controlled Study of the Efficacy and Safety of 0.15% & 0.25% Concentrations of Topical SM04554 Solution in Male Subjects With Androgenetic 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.

Read the detailed description

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Absolute Non-vellus Hair Count in Target Area

    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.

    Measured: Week 48

  9. Improvement in Subject Assessment of Hair Growth

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Topical SM04554 0.15% solution and Topical SM04554 0.25% solution in people with Androgenetic Alopecia, run by Biosplice Therapeutics, Inc. at 14 sites in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 14 sites in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 1 Oct 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Absolute Non-vellus Hair Count in Target Area (time frame: Week 48). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Oct 2026.
