The Food and Drug Administration has approved a topical anticholinergic, sofpironium topical gel, 12.45%, for the treatment of primary axillary hyperhidrosis in adults and children aged ≥ 9 years.
According to a press release from Botanix Pharmaceuticals, which developed the product and will market it under the brand name Sofdra, approval was based on results from two phase 3 studies that enrolled 710 patients with primary axillary hyperhidrosis. In the trials, patients treated with sofpironium topical gel, 12.45%, experienced "clinically and statistically meaningful changes" from baseline in the Gravimetric Sweat Production and the Hyperhidrosis Disease Severity Measure-Axillary seven-item score, according to the company.
Botanix plans to enable qualified patients to gain early access to the product in the third quarter of 2024, with commercial sales expected in the fourth quarter of 2024.
