Item 7.01. Regulation FD Disclosure.

On October 7, 2021, Brickell Biotech, Inc. (the “Company”) issued a press release, which is furnished as Exhibit 99.1 to this report, reporting positive topline results, achieving statistical significance on all primary and secondary endpoints, from its U.S. Phase 3 pivotal Cardigan I and Cardigan II clinical studies of sofpironium bromide gel, 15% in primary axillary (underarm) hyperhidrosis patients. In the Cardigan I and II studies, sofpironium bromide gel, 15% was generally well-tolerated.

The information in this Item 7.01, and Exhibit 99.1 attached hereto, is being furnished and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, regardless of any general incorporation language in such filing.

Item 8.01. Other Events.

On October 7, 2021, the Company announced positive topline results, achieving statistical significance on all primary and secondary endpoints, from its U.S. Phase 3 pivotal Cardigan I and Cardigan II clinical studies, which evaluated sofpironium bromide gel, 15% as a once daily topical formulation in patients with primary axillary hyperhidrosis (excessive underarm sweating). The U.S. Phase 3 pivotal clinical program for sofpironium bromide gel, 15% was comprised of two pivotal clinical studies. The Cardigan I and Cardigan II studies enrolled 350 subjects and 351 subjects, respectively, who were nine years of age and older with primary axillary hyperhidrosis. The studies were multicenter, randomized, double-blinded, vehicle (placebo)-controlled, evaluating the efficacy and safety of topically applied sofpironium bromide gel, 15%. Subjects applied sofpironium bromide gel, 15% or placebo to their underarms once daily at bedtime for six consecutive weeks, with a two-week post-treatment follow-up.

The Company expects that the results from the Cardigan I and Cardigan II studies, along with all previously completed clinical studies, will form the basis for a U.S. New Drug Application for sofpironium bromide gel, 15%, that it anticipates it will submit to the U.S. Food and Drug Administration in mid-2022.

All primary and secondary efficacy endpoints of the Cardigan I and Cardigan II studies demonstrated statistically significant differences between sofpironium bromide gel, 15% (SB) and vehicle (or placebo), as follows:

Cardigan I and II Safety Results

In the Cardigan I and II studies, sofpironium bromide gel, 15% was generally well-tolerated. The Treatment-Emergent Adverse Events (“TEAEs”) were mild or moderate in severity and transient in nature. Overall, 89% of patients who were randomized to sofpironium gel, 15% in the studies completed the full six weeks of treatment. Common adverse events (incidence ≥2%) observed in the sofpironium bromide gel, 15% treatment group in the Cardigan I and II studies were dry mouth (11.6%, 17.2%), blurred vision (5.2%, 11.7%), application site pain (6.4%, 10.0%), application site erythema (5.2%, 7.8%), mydriasis (7.5%, 5.0%), application site pruritis (6.4%, 2.2%), application site dermatitis (5.8%, 5.6%), urinary retention (1.2%, 3.3%), application site irritation (1.2%, 3.3%), dry eye (0.6%, 3.3%), headache (1.2%, 2.2%), constipation (0.6%, 2.2%) and urinary hesitation (0.6%, 2.2%), respectively. Five (2.9%) and nine (5.0%) subjects who received sofpironium bromide gel, 15%, discontinued the Cardigan I and II studies, respectively, due to a TEAE. No treatment-related Serious Adverse Events were reported.
