About this study
Official title: A Randomized, Double Blind, Parallel-group Study to Evaluate the Efficacy and Safety of a New Pharmaceutical Form Minoxidil 5% for the Treatment of Androgenetic Alopecia in Men for 24 Weeks
A prospective, randomized, double-blind, single-center, placebo-Controlled, parallel-group study to evaluate the efficacy and safety of a new pharmaceutical form Minoxidil 5% in men after 24 weeks of treatment.
⚠️Study will only be conducted in research centers in Brazil (please do not send e-mail if your center is outside brazil).
Read the detailed description
Participants will be randomized at a 2: 1 ratio to receive new pharmaceutical form Minoxidil 5% and placebo, respectively. Through this method, it is possible to obtain more information about the effectiveness of investigational product.
The primary objective of the MINOX study is to demonstrate the superiority of a new topical 5% pharmaceutical form of minoxidil (experimental drug) in treating men with androgenetic alopecia (Hamilton-Norwood scale IIIv, IV or V) compared to placebo when administered for 180 days.
Secondary objectives: 1- To evaluate the efficacy of a new topical 5% minoxidil pharmaceutical form in the treatment of men with androgenetic alopecia, compared to placebo, by means of terminal strand density in the target area, evaluated 30 (±3), 60(±3), 90(±3) and 135(±3) days after the beginning of treatment.
2- To evaluate the efficacy of a new topical 5% pharmaceutical form of minoxidil in the treatment of men with androgenetic alopecia, compared to placebo, by means of the percentage of anagen strands in the target area, evaluated 30(±3), 60(±3), 90(±3), 135(±3) and 180(±3) days after the start of treatment.
3- Evaluate the efficacy of a new topical 5% pharmaceutical form of minoxidil in the treatment of men with androgenetic alopecia, compared to placebo, by means of the average length of hair strands in the target area, evaluated 30(±3), 60(±3), 90(±3), 135(±3) and 180(±3) days after the start of treatment.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Minoxidil Topical FoamDrug
Apply 1 mL of solution twice a day.
PlaceboDrug
1 mL of solution twice a day.
| Study group | Role | What they receive |
|---|---|---|
| Minoxidil´s Placebo | Placebo comparator | The recommended dosage is 1 ml of the solution twice a day (morning and evening). Receives: Drug: Placebo |
| Topical Minoxidil 5% | Experimental | The recommended dosage is 1 ml of the solution twice a day (morning and evening). Receives: Drug: Minoxidil Topical Foam |
What is being measured
The primary outcome is the main question the study is designed to answer.
Absolute change in terminal thread density in the target area determined 180 (±3) days after the start of treatment compared to baseline density.
The density of terminal hairs will be evaluated by phototrichogram (FotoFinder leviacam® and Trichoscale Al® Dermatoscope), with the baseline density resulting from the images captured on the VR and VR+2 days visits and the final density resulting from the images captured on the V5 and V5+2 days visits. Terminal wires will be classified as those with diameter greater than or equal to 30 um.
Measured: 24 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Minoxidil Topical Foam in people with Alopecia, run by Eurofarma Laboratorios S.A. at 1 site in Brazil.
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 5 inclusion and 9 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 23 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 1 site in Brazil. 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 phase mean?
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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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 change in terminal thread density in the target area determined 180 (±3) days after the start of treatment compared to baseline density. (time frame: 24 weeks). 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 23 Oct 2026.
