Norwood, MA, Oct. 03, 2018 (GLOBE NEWSWIRE) -- Corbus Pharmaceuticals Holdings, Inc. (NASDAQ: CRBP) (“Corbus” or the “Company”), a clinical stage drug development company with the industry’s leading pipeline focused on treating inflammatory and fibrotic diseases by targeting the endocannabinoid system, announced today that the U.S. Patent and Trademark Office (“USPTO”) issued U.S. Patent No. 10,085,964 to the Company. This patent includes claims covering the use of pharmaceutical compositions comprising lenabasum for the treatment of all fibrotic diseases, including Corbus’ lead indications systemic sclerosis, dermatomyositis, cystic fibrosis and others. The patent provides exclusivity in the U.S. for the use of lenabasum through 2034. This patent follows the previously issued U.S. Patent Nos. 9,801,849 and 9,820,964 covering uses of lenabasum in multiple inflammatory and fibrotic diseases, including systemic lupus erythematosus, multiple sclerosis, rheumatoid arthritis, psoriasis and others.

This new patent is part of an expanding and comprehensive portfolio of patents, patent applications and other intellectual property covering the composition, synthesis, manufacturing, formulation and uses of lenabasum for the treatment of a variety of indications including the Company’s lead indications: systemic sclerosis, dermatomyositis, cystic fibrosis and systemic lupus erythematosus. Lenabasum is a synthetic oral drug candidate designed to resolve chronic inflammation and fibrosis through the activation of CB2 to stimulate production of specialized pro-resolving mediators, inhibition of pro-inflammatory mediators and tissue infiltration with inflammatory cells as well as cessation of fibrogenic processes.

“The issuance of this third key patent reinforces lenabasum’s unique properties to treat diseases that typically have limited therapeutic options for patients,” said Mark Tepper, Ph.D., President and Chief Scientific Officer of Corbus. “This newly issued patent, along with the previously issued U.S. patent Nos. 9,801,849 and 9,820,964, provides Corbus with broad and long-term intellectual property rights to lenabasum through 2034.”

About Lenabasum

Lenabasum is a rationally-designed, oral, small-molecule that selectively binds as an agonist to the cannabinoid receptor type 2 (CB2). CB2 is preferentially expressed on activated immune cells, fibroblasts, muscle cells, and endothelial cells. In both animal and human studies conducted to-date, lenabasum induces the production of Specialized Pro-resolving lipid Mediators (“SPMs”) that activate endogenous pathways which resolve inflammation and speed bacterial clearance without immunosuppression. Lenabasum also has a direct effect on fibroblasts to limit production of fibrogenic growth factors and extracellular connective tissue that lead to tissue fibrosis (scarring). Data from animal models and human clinical studies show lenabasum reduces expression of genes and proteins involved in inflammation and fibrosis. Lenabasum demonstrates promising activity in animal models of skin and lung inflammation and fibrosis in systemic sclerosis (SSc). Lenabasum is also active in animal models of lung infection and inflammation in cystic fibrosis and joint inflammation and scarring in rheumatoid arthritis.

Lenabasum has demonstrated favorable safety and tolerability profiles in clinical studies to date. Lenabasum improved multiple physician-assessed and patient-reported efficacy outcomes in Phase 2 studies in patients with diffuse cutaneous SSc and skin-predominant dermatomyositis. Lenabasum also reduced pulmonary exacerbations in a Phase 2 cystic fibrosis study. Additional clinical studies are being conducted and/or planned to confirm these results and support applications for regulatory approval.

About Corbus

Corbus Pharmaceuticals Holdings, Inc. is a Phase 3 clinical-stage pharmaceutical company focused on the development and commercialization of novel therapeutics to treat inflammatory and fibrotic diseases by leveraging its industry leading pipeline of endocannabinoid system-targeting drug candidates. The Company's lead product candidate, lenabasum, is a novel, synthetic, oral, selective cannabinoid receptor type 2 (CB2) agonist designed to resolve chronic inflammation and fibrotic processes. Lenabasum is currently being evaluated in systemic sclerosis, cystic fibrosis, dermatomyositis, and systemic lupus erythematosus.

Corbus licensed the exclusive worldwide rights to develop, manufacture and market drug candidates from more than 600 novel compounds targeting the endocannabinoid system from Jenrin Discovery LLC. The pipeline includes CRB-4001, a 2nd generation, peripherally-restricted, selective cannabinoid receptor type 1 (CB1) inverse agonist specifically designed to eliminate blood-brain barrier penetration and brain CB1 receptor occupancy that mediate the neuropsychiatric issues associated with first-generation CB1 inverse agonists. Potential indications for CRB-4001 include NASH, primary biliary cholangitis, idiopathic pulmonary fibrosis, radiation-induced pulmonary fibrosis, myocardial fibrosis after myocardial infarction and acute interstitial nephritis, among others. CRB-4001 is scheduled to enter a Phase 1 study in 2019 followed a National Institutes of Health (NIH)-funded first-in-patient Phase 2 study.
