Part I Business Corbus Pharmaceuticals is a Phase 3 clinical-stage company developing therapeutics for inflammatory and fibrotic diseases by targeting the ECS Overview and Pipeline Corbus is a Phase 3 company developing novel therapeutics for chronic inflammatory and fibrotic diseases, with lead drug lenabasum and pipeline candidate CRB-4001 - Corbus is a Phase 3 clinical-stage company focused on developing drugs for inflammatory and fibrotic diseases by targeting the endocannabinoid system (ECS)18 - The lead drug candidate is lenabasum, a novel, synthetic, oral cannabinoid (CB2 agonist) designed to resolve chronic inflammation and halt fibrotic processes18 - Lenabasum is in development for four indications: Systemic Sclerosis (SSc), Dermatomyositis (DM), Cystic Fibrosis (CF), and Systemic Lupus Erythematosus (SLE)1820 - The pipeline includes CRB-4001, a 2nd generation CB1 inverse agonist for fibrotic liver diseases like NASH, with a Phase 1 study expected by the end of 20191885 Clinical Development - Lenabasum Lenabasum is advancing through late-stage clinical trials for SSc, CF, DM, and SLE, with Phase 3 studies ongoing and positive open-label extension data Lenabasum Clinical Trial Status | Indication | Phase | Enrollment Target | Expected Completion | | :--- | :--- | :--- | :--- | | Systemic Sclerosis (SSc) | Phase 3 (RESOLVE-1) | ~354 patients | 2020 | | Cystic Fibrosis (CF) | Phase 2b | ~415 patients | 2020 | | Dermatomyositis (DM) | Phase 3 (DETERMINE) | ~150 patients | Not specified | | Systemic Lupus Erythematosus (SLE) | Phase 2 | ~100 patients | Not specified | - Open-label extension (OLE) studies in SSc and DM are ongoing, showing continued positive efficacy data, with 87% of SSc subjects achieving a clinically meaningful reduction in mRSS (≥ 5 points) at 18 months2031 - The FDA has granted lenabasum Orphan Drug Designation for SSc, CF, and DM, and Fast Track Status for SSc and CF, with EMA also granting Orphan Designation for all three indications22 Lenabasum's Mechanism of Action Lenabasum functions as a pro-resolving drug by selectively binding to the CB2 receptor, stimulating Specialized Pro-Resolving Lipid Mediators (SPMs) to resolve inflammation and halt fibrosis - Lenabasum is a synthetic, oral small-molecule that selectively binds to the CB2 receptor, which is found on activated immune cells and fibroblasts69 - It stimulates the production of Specialized Pro-Resolving Lipid Mediators (SPMs) that resolve inflammation and halt fibrosis without being immunosuppressive6973 - A human clinical study demonstrated that lenabasum increases pro-resolving lipid mediators and decreases inflammatory lipid mediators, providing evidence of its unique pro-resolution mechanism in humans787983 Market Opportunity and Competition Corbus targets rare inflammatory and fibrotic diseases with significant unmet medical needs, including SSc and CF, facing competition from large pharmaceutical firms Estimated Patient Populations (U.S., Europe, Japan) | Indication | Estimated Patients | | :--- | :--- | | Systemic Sclerosis (SSc) | ~200,000 | | Dermatomyositis (DM) | ~80,000 | | Systemic Lupus Erythematosus (SLE) | ~550,000 | | Cystic Fibrosis (CF) | ~70,000 | - There are no FDA-approved treatments specifically for Systemic Sclerosis (SSc), representing a significant unmet medical need92 - In Cystic Fibrosis (CF), lenabasum aims to reduce pulmonary exacerbations, a key driver of morbidity and mortality for which there are no currently approved drugs111112 - Competition includes several large pharmaceutical companies (Boehringer Ingelheim, Galapagos, GSK) developing drugs for SSc and existing CF therapies from companies like Vertex and Celtaxsys126127 Intellectual Property Corbus has secured U.S. patents for lenabasum through 2034 and obtained Orphan Drug Designation in the U.S. and EU, along with licensed IP for CRB-4001 - U.S. patents have been issued covering compositions of lenabasum and its use in treating inflammatory and fibrotic diseases, providing exclusivity through 2034131132133134 - Lenabasum has received Orphan Drug Designation in the U.S. (7 years exclusivity) and EU (10 years exclusivity) for SSc, CF, and DM136 - An exclusive license from Jenrin Discovery provides worldwide rights to over 600 cannabinoid compounds, including CRB-4001, with U.S. patent protection extending to July 2033135 Regulatory Matters The company's products are subject to extensive regulation, with lenabasum classified as a Schedule I controlled substance requiring DEA oversight - Lenabasum is currently classified as a Schedule I controlled substance under the U.S. Controlled Substances Act (CSA), requiring strict DEA oversight for manufacturing, distribution, and clinical trials167270 - If lenabasum receives FDA approval, the DEA will need to conduct a scheduling determination to place it in a schedule other than Schedule I before it can be commercially prescribed275 - The company has received Orphan Drug Designation for lenabasum in SSc, CF, and DM, which provides seven years of market exclusivity in the U.S. upon approval154 - Fast Track Designation has been granted for lenabasum in SSc and CF, intended to facilitate the development and expedite the review of drugs for serious conditions with unmet medical needs136 Risk Factors The company faces significant risks, including operating losses, dependency on lenabasum, outsourced manufacturing, regulatory hurdles, and intellectual property challenges - Financial Risk: The company has a history of operating losses ($55.7 million in 2018) and will require significant additional capital to complete clinical trials and commercialize its products189190192 - Product Dependency: The business heavily depends on the successful development, regulatory approval, and commercialization of its lead candidate, lenabasum201 - Regulatory and Manufacturing Risk: Lenabasum is a Schedule I controlled substance, requiring DEA licenses and compliance, which could cause delays.
