About CRB-913

CRB-913 is an oral small molecule inverse agonist of the G-protein Coupled Receptor (GPCR) cannabinoid type-1 (CB1). This is a recognized mechanism of action for weight loss, but the first generation of experimental drugs in this class was abandoned due to potential neuropsychiatric adverse event risks. CRB-913 is a highly peripherally restricted CB1 inverse agonist designed to have reduced brain penetration. Preclinical models have shown CRB-913 to be 15-fold less brain-penetrant than monlunabant (another experimental CB1 inverse agonist) and to have 50 times lower brain:plasma ratio than rimonabant (an extensively studied first-generation CB1 inverse agonist).
