Brickell Biotech Announces Issuance of New Composition of Matter Patent on Sofpironium Bromide by the Japanese Patent Office
Claims directed to novel crystalline forms of sofpironium bromide
Patent protection in Japan granted through 2040
BOULDER, Colo., Aug. 31, 2020 (GLOBE NEWSWIRE) -- Brickell Biotech, Inc. (“Brickell”) (Nasdaq: BBI), a clinical-stage pharmaceutical company focused on developing innovative and differentiated prescription therapeutics for the treatment of debilitating skin diseases, announced today that Brickell and its Japanese development partner, Kaken Pharmaceutical Co., Ltd. (“Kaken”), 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, a retrometabolically designed new chemical entity, currently under development in the United States and Japan as a potential best-in-class treatment for primary axillary hyperhidrosis. This patent is expected to provide additional protection in Japan through 2040 for these newly developed and distinct characterized crystalline forms of sofpironium bromide. Patent protection for these crystalline forms of sofpironium bromide currently is being pursued worldwide, including in the United States.
“The issuance of this new composition of matter patent is a key accomplishment in protecting and expanding upon our intellectual property portfolio,” commented Robert Brown, Chief Executive Officer of Brickell. “We are pleased by this important new patent issuance in Japan, as well as the continued progress Kaken is making in their commercial planning for sofpironium bromide in Japan. Kaken expects to receive a regulatory decision for sofpironium bromide gel, 5% in Japan, later this year.”
About Sofpironium Bromide
Sofpironium bromide is a proprietary 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. This proposed mechanism of action may allow for highly effective doses to be used while limiting systemic side effects. 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. Sofpironium bromide is not approved for use in any country at this time.
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 more than 16 million people, or 12.76% of the population in Japan, are believed to suffer from hyperhidrosis1,2. 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 or 10 million individuals and an estimated 45% of patients with hyperhidrosis in Japan or 7.2 million individuals1,2.
