BOULDER, Colo., March 09, 2021 (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 fourth quarter and full year ended December 31, 2020 and provided a corporate update.

“Over the last several months, we achieved a number of important milestones – including the initiation of the U.S. pivotal Phase 3 clinical program – that have enabled us to continue developing sofpironium bromide as a potential 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. “This momentum is carrying over into 2021, as we have already exceeded 50% enrollment for the Cardigan I study and remain on track to announce topline data from both the Cardigan I and II studies by the end of the year. If successful, we expect the data from these studies to form the basis of an NDA submission to the FDA.”

Mr. Brown continued, “In addition to the great progress we’ve made in the last quarter at Brickell, our Japanese development partner, Kaken, was successful in executing its clinical development program for ECCLOCK^®. This progress is highlighted by the approval, placement on Japan’s National Health Insurance reimbursement price list, and recent commercial launch of ECCLOCK^® in Japan. Of note, Japan is the first country to approve sofpironium bromide, which also represents the first topical prescription product to be marketed for the treatment of primary axillary hyperhidrosis in the country. Kaken has proven to be a valuable partner, and we look forward to seeing the ramp up of their commercialization program for ECCLOCK^®, which will provide Brickell with royalties and potential sales-based milestone payments per our sublicense agreement.”

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 for sofpironium bromide gel, 15%. In addition, recent aggregate net proceeds of $10.5 million from warrant exercises and sales of shares under a previously filed At-The-Market (“ATM”) Equity Offering Program have further strengthened the Company’s financial position.
• Initiated enrollment in the U.S. Phase 3 Cardigan I (October 2020) and Cardigan II (December 2020) studies evaluating sofpironium bromide gel, 15% in approximately 350 subjects (per study) aged nine and older with primary axillary hyperhidrosis.

Financial Results

Fourth Quarter 2020 Financial Results

The Company reported cash and cash equivalents and marketable securities of $30.1 million as of December 31, 2020, compared to $11.7 million as of December 31, 2019. In addition, as of December 31, 2020, Brickell had $2.3 million in prepaids to third-party clinical research organizations as part of conducting its U.S. pivotal Phase 3 clinical trials of sofpironium bromide gel, 15%. During the fourth quarter of 2020, the Company completed a public equity offering resulting in net proceeds of approximately $13.7 million. Subsequent to the end of the fourth quarter, the Company received aggregate net proceeds of $10.5 million from warrant exercises and sales of shares under a previously filed ATM Equity Offering Program.

Revenue was approximately $27 thousand for the fourth quarter of 2020, compared to $0.7 million for the fourth quarter of 2019. Revenue in 2020 was driven by royalty income from sales of ECCLOCK^® in Japan by Kaken, while revenue in 2019 was driven by collaboration revenue recognized for research and development activities related to a license 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 was the basis for revenue recognition over time, through the third quarter of 2020, of a $15.6 million research and development payment received from Kaken in the second quarter of 2018. In late 2020, Brickell began recognizing royalty revenue earned on a percentage of net sales of sofpironium bromide in Japan in the fourth quarter.

Research and development expenses were $4.6 million for the fourth quarter of 2020, compared to $6.6 million for the fourth 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. Brickell began incurring greater research and development costs upon the initiation of its Phase 3 Cardigan Studies in the fourth quarter of 2020.

General and administrative expenses were $2.9 million for the fourth quarter of 2020, compared to $4.9 million for the fourth quarter of 2019. This decrease was primarily due to lower costs of $1.4 million for professional-related fees associated with the merger with Vical Incorporated that occurred in the third quarter of 2019 as well as reduced impairment expense of $0.8 million and other miscellaneous expenses of $0.4 million, partially offset by higher costs of $0.6 million for compensation-related expense.

Brickell’s net loss was $7.4 million for the fourth quarter of 2020 compared to $10.9 million for the fourth quarter of 2019.

Full Year 2020 Financial Results

Revenue was $1.8 million for the year ended December 31, 2020, compared to $7.9 million for the year ended December 31, 2019. Revenue in both periods was driven primarily by collaboration revenue recognized for research and development activities related to a license agreement with Kaken for 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 was the basis for revenue recognition over time, through the third quarter of 2020, of a $15.6 million research and development payment received from Kaken in the second quarter of 2018. In late 2020, Brickell began recognizing royalty revenue earned on a percentage of net sales of sofpironium bromide in Japan, which amounted to approximately $27 thousand in the fourth quarter.

Research and development expenses were $11.2 million for the year ended December 31, 2020, compared to $20.2 million for the year ended December 31, 2019, which was driven primarily by a decrease in clinical and other related regulatory and compliance costs related to sofpironium bromide. The Company’s Phase 3, open-label, long-term safety study of sofpironium bromide gel and other ancillary clinical studies were ongoing in 2019 but were concluded or winding down by the end of the first quarter of 2020. Brickell began incurring greater research and development costs upon the initiation of its Phase 3 Cardigan Studies in the fourth quarter of 2020.

General and administrative expenses were $11.6 million for the year ended December 31, 2020, compared to $12.2 million for the year ended December 31, 2019. This decrease was primarily due to reduced professional fees of $1.8 million resulting from legal and other fees incurred in 2019 related to the merger with Vical that did not recur in 2020, as well as reduced impairment expense of $0.8 million in 2020 compared to 2019. These reduced expenses were partially offset by higher costs in 2020 of $2.0 million for compensation-related expense and $0.8 million for directors’ and officers’ liability insurance due to becoming a public company.

Total other income, net was $0.1 million for the year ended December 31, 2020, compared to $0.6 million for the year ended December 31, 2019. The decrease of $0.5 million was primarily due to a gain of $2.3 million related to the conversion of the convertible promissory notes in August 2019 and a gain of $0.2 million resulting from fair value adjustments to warrant liabilities during the year ended December 31, 2019, both of which did not recur in 2020. These gains were partially offset by a decrease of $2.1 million in interest expense related to the issuance of convertible promissory notes in 2019 and principal borrowings provided by a loan agreement with a former lender.

Brickell’s net loss was $20.9 million for the year ended December 31, 2020, compared to $23.9 million for the year ended December 31, 2019.

About Sofpironium Bromide

Sofpironium bromide is Brickell’s lead investigational product candidate and is a 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 intended to exert their action locally 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 debilitating, life-altering medical condition where a person sweats beyond what is physiologically required for thermoregulation of the body. 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^2,3. 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/.
