FDA Rejects Anti-Sweating Gel
FDA has sent Botanix Pharmaceuticals a complete response letter on its NDA for sofpironium bromide gel, indicated for treating primary axillary hyperhidrosis. The company says it will need to revise the printed Instructions for Use document proposed for inclusion with the product, and other unspecified points raised in the letter. It notes that no clinical efficacy, safety or manufacturing issues were cited in the letter, and no additional clinical studies are required to support approval. An NDA resubmission is expected in the first quarter of 2024, which could lead to an approval by mid-year.
New chemical entity sofpironium bromide is described as an anticholinergic/antimuscarinic drug that blocks sweating at the gland by binding to the receptor and thereby blocking the sweat signal. The company says about 85% of patients using the gel experienced a clinically meaningful improvement in their condition over the course of its Phase 3 studies. It adds that there were no treatment-related serious adverse events in any of the studies and adverse events were characterized as transient and mild to moderate in nature.
