The US Food and Drug Administration (FDA) has approved topical glycopyrronium ( Qbrexza Dermira) for the treatment of adults and children 9 years of age with primary axillary hyperhidrosis.
Qbrexza is a topical anticholinergic cloth that is applied to the underarms to prevent sweat production by inhibiting sweat gland activation.
The safety and efficacy of Qbrexza for primary axillary hyperhidrosis has been investigated in two phase 3 clinical trials (ATMOS-1 and ATMOS-2). Both studies assessed the absolute change in sweat production after treatment with Qbrexza from baseline, along with the proportion of patients who were at least 4 points above baseline in DTS, as measured by Dermira's Axillary Sweating Daily Diary (ASDD) Patient reported outcome (PRO) instrument. The PRO was developed in consultation with the FDA and in accordance with the Agency's 2009 PRO Instruments Guidelines.
With Qbrexza, patients experienced a "noticeable and sustained reduction in their total sweat production," the company said in a press release with FDA approval.
