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).

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.

Masking will be adopted in this study, in which the experimental products under evaluation will be provided in a masked way, that is, one group will receive an experimental drug (Minoxidil 5%) and another group will receive a placebo (product without the active ingredient) in identical primary and secondary packaging to avoid potential bias, so neither the researcher nor the research participant will know what is being applied.
