Item 7.01. Regulation FD Disclosure.
On April 23, 2021, Brickell Biotech, Inc. (the “Company”) issued a press release, which is furnished as Exhibit 99.1 to this report, reporting results from its U.S. Phase 3 open-label, long-term safety study of sofpironium bromide gel as a potential treatment for primary axillary (underarm) hyperhidrosis. An investor presentation that the Company will refer to during a conference call to discuss the results is furnished as Exhibit 99.2 to this report.
The information in this Item 7.01, and Exhibits 99.1 and 99.2 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 April 23, 2021, the Company announced results from its Phase 3 open-label, long-term safety study (“ARGYLE” or “LTSS”). The ARGYLE study assessed the long-term safety and efficacy of topical, once-daily treatment with sofpironium bromide gel, 5% and 15% for 48 weeks in patients nine years and older with primary axillary hyperhidrosis, or excessive underarm sweating.
The study enrolled 300 patients at 30 U.S. sites, and patients were randomized to receive either sofpironium bromide gel, 5% or 15% in a 1:2 ratio. Subjects applied the assigned investigational product once daily at bedtime to both axillae for 48 weeks, followed by a 4-week post-treatment visit. This study was not conducted as a conventional Phase 3 open-label “extension” study where patients from pivotal studies roll over into an open-label extension study. ARGYLE thus provides a more complete clinical data set evaluating treatment-naïve primary axillary hyperhidrosis patients who received sofpironium bromide gel for 48 weeks. 190 patients completed the full study duration of 52 weeks.
The treatment-related treatment-emergent adverse events (TEAEs) for sofpironium bromide gel, 5% (22.5%) and 15% (50.8%) were mostly mild or moderate in severity and transient in nature. The most common and expected treatment-related TEAEs reported were blurred vision (4.9%; 18.8%), dry mouth (8.8%; 16.8%), pruritis (5.9%; 14.7%), pain (3.9%; 14.7%), dermatitis (5.9%; 9.1%), erythema (4.9%; 7.6%), irritation (4.9%; 5.6%), mydriasis (1.0%; 5.1%) and urinary retention (2.9%; 3.6%). The patient discontinuations due to treatment-related TEAEs included blurred vision (2.0%; 7.1%), pruritis (0%; 2.0%), dermatitis (1.0%; 2.0%), dry mouth (0%; 1.5%), pain (0%; 1.5%), erythema (1.0%; 0.5%), irritation (0%; 1.0%), urinary hesitation (1.0%; 0%) and mydriasis (0%; 0.5%). Overall, TEAEs and discontinuations demonstrated decreased incidence over time as patients in the long-term study acclimated to treatment. No treatment-related serious adverse events (SAE) were observed in adult and pediatric patients and no new safety signals emerged.
With respect to studied efficacy, the 5% and 15% gel groups exhibited clinically meaningful improvement in axillary hyperhidrosis severity as measured by the Hyperhidrosis Disease Severity Measure-Axillary (HDSM-Ax), a proprietary patient-reported outcome scale. For both 5% and 15% dose groups, responders with a 1-point (86.1%; 85.8%) and 2-point (69.4%; 61.9%) improvement on HDSM-Ax PRO scale showed a gradual and continual improvement in sweat severity through the 48 weeks of treatment.
Overall, the safety, tolerability and efficacy results for sofpironium bromide gel, 5% and 15% in ARGYLE were consistent with prior clinical experience and no unexpected safety findings were observed. There were no clinically significant changes in laboratory parameters or vital signs over 48 weeks of treatment.
