BOULDER, Colo., March 15, 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 fourth quarter and full year ended December 31, 2021 and provided a corporate update.

“Over the course of the last year, the entire Brickell team successfully executed on our strategic plan,” commented Robert Brown, Chief Executive Officer of Brickell. “Our robust pipeline of recently-acquired proprietary drug candidates firmly establishes our presence in the immunology and inflammation fields with multiple promising and novel targets. We are on track to advance our lead DYRK1A inhibitor, BBI-02, into a Phase 1 clinical study in the coming months, and the team is progressing the development of our lead STING inhibitor, BBI-10, and other next-generation kinase inhibitors through early preclinical stage studies. In addition, we continue to execute towards a mid-2022 NDA submission for sofpironium bromide gel, 15% for the treatment of primary axillary hyperhidrosis and evaluate all available options designed to maximize commercial product success. We believe 2022 is shaping up to be a pivotal year for Brickell, and we look forward to providing updates on our progress across these exciting programs in the coming months.”

Research and Development Highlights

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

• Brickell is on track to progress BBI-02, its lead development-stage program, into a Phase 1 clinical trial (BBI-02-101) in Canada in the second quarter of 2022.
• BBI-02-101: This Phase 1 study is expected to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of BBI-02 in both healthy volunteers and subjects with atopic dermatitis (AD) and will also include a preliminary assessment of efficacy as to AD.
  • Part 1A of the study will be a single ascending dose (SAD) assessment in healthy volunteers, Part 1B of the study will be a multiple ascending dose (MAD) assessment in healthy volunteers, and Part 2 of the study will compare BBI-02 to placebo in moderate-to-severe AD patients.
  • Topline results from the SAD and MAD parts of the Phase 1 study anticipated year-end 2022.

BBI-10: a covalent STING inhibitor for the potential treatment of autoinflammatory and rare genetic diseases

• In February 2022, Brickell acquired exclusive global rights to develop and commercialize a portfolio of novel, potent, and orally available Stimulator of Interferon Genes (STING) inhibitors from Carna Biosciences, Inc., which have potential to treat autoinflammatory disorders, such as systemic lupus erythematosus and rheumatoid arthritis, rare genetic interferonopathies, and potentially other diseases.
• Preclinical development activities for BBI-10 are underway, and the Company expects to conduct experimental characterization of the STING inhibitor library throughout 2022.

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

• Currently engaged in research to identify both brain penetrant and non-brain penetrant kinase inhibitors from the Company’s licensed library of compounds, including next-generation DYRK1A inhibitors and other new chemical entities that specifically inhibit LRRK2, TTK, and CLK kinases, as potential treatments for autoimmune, inflammatory, and other debilitating diseases.

Sofpironium Bromide: a potential best-in-class investigational product for the treatment of primary axillary hyperhidrosis

• Following a pre-NDA meeting held with the U.S. FDA earlier this quarter, the Company remains on track to file an NDA for sofpironium gel, 15% in mid-2022.
• Results from Brickell’s U.S. Phase 3 pivotal Cardigan I and Cardigan II studies of sofpironium bromide gel, 15% were selected for an oral presentation at the Late-Breaking Research session during the American Academy of Dermatology’s 2022 Annual Meeting, which is being held from March 25-29 in Boston, MA.
• Brickell’s development partner, Kaken Pharmaceutical Co., Ltd. (Kaken), continues to commercialize sofpironium bromide gel, 5% (ECCLOCK^®) for the treatment of primary axillary hyperhidrosis in Japan.

Financial Results

Fourth Quarter 2021 Financial Results

The Company reported cash and cash equivalents of $26.9 million as of December 31, 2021, compared to $30.1 million as of December 31, 2020. The Company expects its cash and cash equivalents will support operations beyond the receipt of Phase 1 SAD and MAD topline results for BBI-02, which are anticipated year-end 2022.

Revenue was $104.0 thousand for the fourth quarter of 2021, compared to $27.0 thousand for the fourth quarter of 2020. Revenue in both periods related to royalty revenue recognized from sales of ECCLOCK in Japan by Kaken.

Research and development expenses were $3.1 million for the fourth quarter of 2021, compared to $4.6 million for the fourth quarter of 2020. This decrease was primarily due to a $2.9 million reduction in clinical costs related to sofpironium bromide, which was partially offset by a $0.9 million increase in regulatory, personnel, and other expenses, and a $0.5 million increase related to development of the Company’s DYRK1A inhibitor programs.

General and administrative expenses were $3.3 million for the fourth quarter of 2021, compared to $2.9 million for the fourth quarter of 2020. The increase of $0.4 million was primarily due to compensation and administrative expenses.

Brickell’s net loss was $6.1 million for the fourth quarter of 2021 compared to $7.4 million for the fourth quarter of 2020.

2021 Annual Financial Results

Revenue was $0.4 million for the year ended December 31, 2021, compared to $1.8 million for the year ended December 31, 2020. Revenue in 2021 consisted of royalty revenue recognized related to sales of ECCLOCK in Japan by Kaken, while revenue in 2020 was driven primarily by collaboration revenue recognized for research and development activities under an agreement pursuant to which Kaken provided research and development funding to the Company.

Research and development expenses were $28.2 million for the year ended December 31, 2021, compared to $11.2 million for the year ended December 31, 2020, which was primarily due to an increase of $10.7 million in clinical costs related to the Company’s U.S. Phase 3 pivotal clinical program for sofpironium bromide gel, 15%, an increase of $5.4 million in upfront costs and development expenses related to the Company’s DYRK1A inhibitor programs and next-generation kinase inhibitor platform, and an increase of $0.9 million in personnel and other expenses.

General and administrative expenses were $12.4 million for the year ended December 31, 2021, compared to $11.6 million for the year ended December 31, 2020. The increase of $0.8 million was primarily due to compensation and administrative expenses.

Total other income, net was $0.8 million for the year ended December 31, 2021, compared to $0.1 million for the year ended December 31, 2020. The increase of $0.7 million was primarily due to a gain on extinguishment of debt of approximately $0.4 million that resulted from the forgiveness of a loan in June 2021 and other miscellaneous income of $0.3 million.

Brickell’s net loss was $39.5 million for the year ended December 31, 2021, compared to $20.9 million for the year ended December 31, 2020.
