Product name: lenabasum

Compound: lenabasum

Therapeutic area: Fibrotic diseases

Action mechanism:

  • cannabinoid receptor agonist. 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.
  • Lenabasum has been 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.
  • 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 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.
