Corbus Pharmaceuticals Announces Three Lenabasum Abstracts to be Presented at ACR Convergence 2020

  • Preliminary baseline subject demographics and disease characteristics in a Phase 3 clinical trial of the safety and efficacy of lenabasum in dermatomyositis (DETERMINE)
  • Cannabinoid receptor type 2 expression is increased in lesional dermatomyositis skin compared to healthy skin and lenabasum significantly reduces CD8+ T cell expression of interferon γ

About Lenabasum

Lenabasum is a novel, oral, small molecule that selectively binds as an agonist to the cannabinoid receptor type 2 (CB2) and resolves inflammation and limits fibrosis in animal and human models of disease. CB2 is preferentially expressed on activated immune cells and on fibroblasts, muscle cells, and endothelial cells. Lenabasum has demonstrated acceptable safety and tolerability profiles in clinical studies to date.

About Dermatomyositis

Dermatomyositis (DM), a form of myositis, is a chronic, rare, inflammatory, clinically heterogenous, life-threatening autoimmune disease affecting approximately 80,000 people in North America, EU and Japan.1 The signs and symptoms of DM reflect multi-organ involvement, which includes distinctive skin rashes usually accompanied by proximal muscle weakness, and can also include pulmonary, cardiac, gastrointestinal, and joint involvement.2 Patients with DM can have recurrent disease flares or chronic progressive disease activity, with increased mortality.3,4 The current mainstay of treatments include FDA-approved systemic glucocorticoids, adrenocorticotropic hormone analogue and off-label use of glucocorticoid-sparing immunosuppressive agents.5,6 There is significant unmet need for new treatments to achieve disease control in DM because of limited efficacy or toxicity of immunosuppressive agents or refractory disease.7,8

About Systemic Sclerosis

Systemic sclerosis, a form of scleroderma, is a chronic, rare, debilitating autoimmune disease affecting approximately 200,000 people in the North America, EU and Japan.1 Systemic sclerosis is considered one of the most life-threatening rheumatic diseases.9 The disease affects the skin and internal organs and is driven by inflammation and fibrosis (scarring of tissue) which can lead to severe damage and failure of multiple organs including the skin, joints, tendons, gastrointestinal tract, lungs, heart, blood vessels and kidneys.10 There is no cure for systemic sclerosis, and current treatments address the clinical manifestations of the disease, not the underlying mechanisms that drive inflammation and fibrosis.11
