• Recently completed capital raise expected to fully fund U.S. pivotal Phase 3 program, with topline results anticipated in Q4 2021
• Initiated the Cardigan I study, the first of two U.S. pivotal Phase 3 clinical studies evaluating sofpironium bromide gel, 15% as a potential treatment for primary axillary hyperhidrosis
• On track to initiate the Cardigan II study, the second U.S. pivotal Phase 3 clinical study, later this year
• Planned commercial launch of ECCLOCK® in Japan by development partner, Kaken, expected by the end of 2020, which follows regulatory approval received in the third quarter

BOULDER, Colo., Nov. 12, 2020 (GLOBE NEWSWIRE) -- Brickell Biotech, Inc. (“Brickell” or the “Company”) (Nasdaq: BBI), a clinical-stage pharmaceutical company focused on developing innovative and differentiated prescription therapeutics for the treatment of debilitating skin diseases, today announced financial results for the third quarter ended September 30, 2020 and provided a corporate update.

“I am proud of the focus, drive and determination that the Brickell team has shown in 2020, which has allowed us to execute against our corporate goals. As a result, we are now well-positioned to continue executing our strategy to develop sofpironium bromide as a potentially best-in-class treatment option for the more than 10 million people in the U.S. suffering with primary axillary hyperhidrosis,” commented Robert Brown, Chief Executive Officer of Brickell. “Last month, we initiated the Cardigan I registration trial and completed an equity financing, which provided us with additional capital needed to initiate the Cardigan II second registration trial later this year and is expected to allow us to complete the U.S. pivotal Phase 3 program, with topline results anticipated in the fourth quarter of 2021.”

“The third quarter was a productive period for our Japanese development partner, Kaken, who recently received regulatory approval for ECCLOCK^® (sofpironium bromide gel, 5%) in Japan for the treatment of primary axillary hyperhidrosis. Japan is the first country to approve sofpironium bromide for any indication and Kaken remains on target for commercial launch later this year. We are thrilled with the progress that both Brickell and Kaken have made and look forward to providing updates on the advancement of our U.S. pivotal Phase 3 program, as well as Kaken’s launch efforts in Japan, over the coming months,” concluded Mr. Brown.

Business and Recent Developments

• Completed an equity financing in October 2020 resulting in net proceeds of approximately $13.7 million that strengthened the Company’s balance sheet and is expected to fully fund its operations through topline results of the U.S. pivotal Phase 3 program.
  
• Initiated the U.S. Phase 3 Cardigan I clinical trial, a multicenter, randomized, double-blinded, vehicle (placebo)-controlled study to evaluate the safety and efficacy of topically applied sofpironium bromide gel, 15% for the treatment of primary axillary (underarm) hyperhidrosis. Subjects will apply sofpironium bromide or vehicle once daily at bedtime to their underarms for six consecutive weeks, with a two-week post-treatment follow-up. The study is expected to enroll up to 350 subjects aged nine years and older with primary axillary hyperhidrosis.
  
• Japanese development partner, Kaken Pharmaceutical, Co., Ltd. (“Kaken”), received regulatory approval in Japan to manufacture and market sofpironium bromide gel, 5% for the treatment of primary axillary hyperhidrosis. This approval was based on the results of Kaken’s Japanese pivotal Phase 3 registration study of sofpironium bromide gel, 5% in 281 patients with primary axillary hyperhidrosis, in which all primary and secondary efficacy endpoints demonstrated statistically significant differences between sofpironium bromide gel and vehicle. In addition, sofpironium bromide gel, 5% was observed to be safe and generally well tolerated in this study, as well as in the accompanying 52-week long-term safety extension study with 185 patients in Japan.
  
• Kaken and Brickell were granted by the Japanese Patent Office a composition of matter patent with claims directed to the novel polymorphic, or crystalline, forms of sofpironium bromide that is expected to provide additional protection for these newly developed and distinct forms in Japan through 2040.
  
• Completed the 12-month Phase 3 open-label long-term safety study evaluating sofpironium bromide gel, 5% and 15% in 300 subjects nine years and older with primary axillary hyperhidrosis. The study results confirmed that sofpironium bromide gel, at both concentrations, was safe and generally well tolerated, which was consistent with the earlier Phase 2 clinical trial results. No treatment-related serious adverse events were observed. The Company expects to release additional details at an upcoming scientific forum.
  
• Entered into a collaboration agreement with AnGes, Inc (“AnGes”) through which the Company has certain rights to develop AnGes’ proprietary investigational adjuvanted plasmid DNA vaccine intended to prevent SARS-CoV-2 (COVID-19) in the U.S., South America and certain other emerging markets. AnGes is currently conducting Phase 1/2 clinical studies with its vaccine candidate in Japan.

Upcoming Milestones

• Plan to initiate the Cardigan II study, the second U.S. pivotal Phase 3 clinical trial, prior to year end. The Cardigan II study will evaluate the safety and efficacy of sofpironium bromide gel, 15% versus vehicle in approximately 350 subjects aged nine years and older with primary axillary hyperhidrosis.
  
• Expect Kaken to launch ECCLOCK^® commercially in Japan by the end of 2020. Under our agreement with Kaken, Brickell is entitled to receive commercial milestone payments, as well as tiered royalties based on a percentage of net sales in Japan.
  
• Expect to report topline data from both the Cardigan I and II U.S. pivotal Phase 3 clinical studies by the end of 2021.
  
• Expect to receive results from the Phase 1/2 clinical studies with AnGes’ COVID-19 vaccine candidate in Japan through the first quarter of 2021. The results from these studies will guide AnGes’ and Brickell’s global development efforts of this novel vaccine candidate.

Financial Results

The Company reported cash and cash equivalents and marketable securities of $20.2 million as of September 30, 2020 compared to $11.7 million as of December 31, 2019. In addition, Brickell has prepaid $4.2 million to third-party clinical research organizations as part of conducting the U.S. pivotal Phase 3 clinical trials of sofpironium bromide. Subsequent to the end of the third quarter, the Company completed a public equity offering resulting in net proceeds of approximately $13.7 million.

Revenue was $0.1 million for the third quarter of 2020 compared to $1.2 million for the third quarter of 2019. Revenue in both periods was driven by research and development activities related to the agreement with Kaken pursuant to which Kaken provided research and development funding to Brickell. The decrease in revenue recognized was attributable to Brickell’s Phase 3 open-label long-term safety study of sofpironium bromide gel and other ancillary clinical studies that were ongoing in 2019 but were concluded or winding down by the end of the first quarter of 2020. Conducting these studies is the basis for revenue recognition of a $15.6 million research and development payment received from Kaken in the second quarter of 2018.

Research and development expenses were $1.3 million for the third quarter of 2020 compared to $3.3 million for the third quarter of 2019. This decrease was primarily due to reduced clinical and other related regulatory and compliance costs of the Phase 3 open-label long-term safety study of sofpironium bromide gel and other ancillary clinical studies that were concluded or winding down by the end of the first quarter of 2020.

General and administrative expenses were $3.2 million for the third quarter of 2020 compared to $3.9 million for the third quarter of 2019. This decrease was primarily due to lower costs of $1.1 million for professional-related fees associated with the merger with Vical Incorporated that occurred in the third quarter of 2019 and $0.4 million for other miscellaneous fees, partially offset by higher costs of $0.6 million for stock and other compensation expense that was driven by increased headcount and $0.2 million for directors’ and officers’ liability insurance due to becoming a public company.

Brickell’s net loss was $4.3 million for the third quarter of 2020 compared to $4.8 million for the third quarter of 2019.

About Sofpironium Bromide

Sofpironium bromide is a proprietary investigational new chemical entity that belongs to a class of medications called anticholinergics. Anticholinergics block the action of acetylcholine, a chemical that transmits signals within the nervous system that are responsible for a range of bodily functions, including activation of the sweat glands. Sofpironium bromide was retrometabolically designed. Retrometabolic drugs are designed to exert their action topically and are potentially rapidly metabolized into a less active metabolite once absorbed into the blood. Sofpironium bromide was discovered at Bodor Laboratories, Inc. by Dr. Nicholas Bodor D.Sc., d.h.c. (multi), HoF, Graduate Research Professor Emeritus, University of Florida.

About Hyperhidrosis

Hyperhidrosis is a life-altering medical condition where a person sweats more than the body requires to regulate its temperature. More than 15 million people, or 4.8% of the population of the United States, and 12.76% of the population in Japan, are believed to suffer from hyperhidrosis^1,2. Primary axillary (underarm) hyperhidrosis is the targeted first indication for sofpironium bromide and is the most common site of occurrence of hyperhidrosis, affecting an estimated 65% of patients with hyperhidrosis in the United States. Additional information can be found on the International Hyperhidrosis Society website: https://www.sweathelp.org/.
