On track to report SAD and MAD topline results from BBI-02 Phase 1 study by early 2023

Development of BBI-10 and next-generation kinase inhibitors advancing through early preclinical stage studies

BOULDER, Colo., Aug. 11, 2022 (GLOBE NEWSWIRE) -- Brickell Biotech, Inc. ("Brickell" or the "Company") (NASDAQ:BBI), a clinical-stage pharmaceutical company striving to transform patient lives by developing innovative and differentiated prescription therapeutics for the treatment of autoimmune, inflammatory, and other debilitating diseases, today announced financial results for the second quarter ended June 30, 2022 and provided a corporate update.

"Advancement of BBI-02 into the clinic is a significant milestone for our company as it marks the first time a DYRK1A inhibitor intended for patients with autoimmune diseases has been orally administered in humans," commented Robert Brown, Chief Executive Officer of Brickell. "We are pleased with the progress in the Phase 1 study and remain on track to initiate the MAD part of the study next month and report SAD and MAD topline results by early 2023."

Research and Development Highlights

BBI-02: a potential first-in-class DYRK1A inhibitor for the treatment of autoimmune and inflammatory diseases

• Continue to enroll and dose patients in the Phase 1 clinical trial of BBI-02 (BBI-02-101) in Canada, a randomized, double-blind, placebo-controlled study designed to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of BBI-02 capsules in both healthy subjects and patients with atopic dermatitis (AD).
  • Part 1A of the study is a single ascending dose (SAD) assessment of BBI-02 capsules or placebo in healthy subjects. Part 1B of the study will be a multiple ascending dose (MAD) assessment of BBI-02 capsules or placebo administered once daily for 14 days in healthy subjects. Part 2 of the study will compare BBI-02 to placebo in patients with moderate-to-severe AD over 28 days of dosing and will include a preliminary assessment of efficacy. Additional information on this clinical trial can be found on www.clinicaltrials.gov under identifier NCT05382819.
  • The Company expects to initiate the MAD assessment next month and remains on track to report topline results from the SAD and MAD parts of the Phase 1 trial by early 2023.
    
    

BBI-10: a covalent Stimulator of Interferon Genes (STING) inhibitor for the potential treatment of autoimmune, inflammatory, and rare genetic diseases

• Preclinical development activities for BBI-10, the Company's lead STING inhibitor candidate, are underway.
  
  

Next-Generation Kinase Inhibitors: a cutting-edge platform with the potential to produce treatments for autoimmune, inflammatory, and other debilitating diseases

• The Company is engaged in research to identify both brain penetrant and non-brain penetrant kinase inhibitors from the Company's library of novel compounds, including next-generation DYRK1A inhibitors and other new chemical entities that specifically inhibit LRRK2, TTK, and CLK kinases.
• A number of these drug candidates have the potential to penetrate the blood brain barrier, presenting an opportunity to address neuroinflammatory conditions of high unmet need such as Down Syndrome, Alzheimer's Disease, and Parkinson's Disease, while other peripherally acting novel LRRK2, TTK, and CLK kinase inhibitors could be developed in additional therapeutic areas within autoimmunity, inflammation, and oncology.

Recent Corporate Highlights

On July 5, 2022, Brickell effected a 1-for-45 reverse stock split of the Company's common stock. Proportional adjustments were also made to the number of shares of Brickell's common stock subject to outstanding equity awards and warrants, as well as the applicable exercise price(s). The purpose of the 1-for-45 reverse stock split was to raise the per-share trading price of the Company's common stock to regain compliance with the $1.00 per share minimum bid price requirement for continuous listing on The Nasdaq Capital Market ("Nasdaq"). On July 19, 2022, the Company received formal notice from Nasdaq stating that the Company had regained compliance with the minimum bid price requirement for continued listing on Nasdaq, and, accordingly, the previously-scheduled hearing regarding the delisting action had been canceled and the Company's common stock will continue to be listed and traded on Nasdaq.

On May 3, 2022, Brickell signed and closed a definitive asset purchase agreement ("APA") with Botanix SB Inc., a subsidiary of Botanix Pharmaceuticals Limited (ASX: BOT) ("Botanix"). Under the terms of the APA, Botanix acquired all of Brickell's rights and assets primarily related to sofpironium bromide. In exchange, Brickell received $3.0 million at closing and is eligible to receive from Botanix potential near-term regulatory milestone payments of (a) $2.0 million upon the acceptance by the U.S. Food and Drug Administration of a new drug application ("NDA") submission for sofpironium bromide gel, 15%, and (b) $4.0 million if marketing approval in the U.S. for sofpironium bromide gel, 15%, is received on or before September 30, 2023, or $2.5 million if such marketing approach is received after September 30, 2023 but on or before February 17, 2024. Brickell also is eligible to receive additional success-based regulatory and sales milestone payments of up to $168 million and tiered earnout payments ranging from high-single digits to mid-teen digits on net sales of sofpironium bromide gel. Certain of these amounts are subject to payments by Brickell to its former licensor. Brickell additionally will receive certain payments from sales by its former sublicensee, Kaken Pharmaceutical Co. ("Kaken"). Under the APA, Botanix is responsible for all further research, development, and commercialization of sofpironium bromide globally. In connection with the sale of sofpironium bromide, Brickell and Botanix entered into a transition services agreement ("TSA") whereby Brickell is providing consulting services to Botanix as an independent contractor through filing and potential approval of the U.S. NDA for sofpironium bromide gel, 15%. Botanix has reported that it plans to submit the NDA for sofpironium bromide gel, 15% in the third quarter of 2022.

Second Quarter 2022 Financial Results

The Company reported cash and cash equivalents of $14.5 million as of June 30, 2022, compared to $26.9 million as of December 31, 2021. The Company expects its cash and cash equivalents as of June 30, 2022, combined with $2.0 million from expected near-term payments under the APA with Botanix, will support its operations for at least the next 12 months.

Revenue was $4.3 million for the second quarter of 2022, compared to $0.2 million for the second quarter of 2021. Revenue for the three months ended June 30, 2022 consisted of contract revenue recognized under the APA and TSA with Botanix, while revenue for the three months ended June 30, 2021 was driven by royalty revenue earned on a percentage of net sales of ECCLOCK in Japan under the Kaken agreement. Contract revenue for the three months ended June 30, 2022 consisted of an upfront payment from Botanix of $3.0 million, reimbursed development expenditures from Botanix under the APA of $0.6 million, fees for consulting services the Company provided under the TSA of $0.4 million, and sublicense income under the APA of $0.3 million.

Research and development expenses were $1.9 million for the second quarter of 2022, compared to $8.8 million for the second quarter of 2021, which decrease was driven primarily by lower clinical expenses related to sofpironium bromide, partially offset by increased clinical costs for BBI-02. Throughout 2021, the Company was executing its U.S. Phase 3 pivotal clinical program for sofpironium bromide gel, 15%, which concluded in the fourth quarter of 2021. During the second quarter of 2022, the Company initiated its Phase 1 clinical trial for BBI-02 and began incurring research and development expenses related to the clinical trial.

General and administrative expenses were $3.9 million for the second quarter of 2022, compared to $2.9 million for the second quarter of 2021. The increase was primarily related to expenses incurred in the second quarter of 2022 associated with entering into the APA and higher legal, compensation, and other administrative fees.

Brickell's net loss was $1.1 million for the second quarter of 2022 compared to $11.1 million for the second quarter of 2021.
