Longboard Pharmaceuticals, Inc. is a clinical-stage biopharmaceutical company focused on developing novel, transformative medicines for neurological diseases. Longboard was formed in January 2020 by Arena to advance a portfolio of centrally acting product candidates designed to be highly selective for specific GPCRs. Longboard’s small molecule product candidates were discovered out of the same platform at Arena that represents a culmination of more than 20 years of GPCR research. Longboard is evaluating LP352, an oral, centrally acting, 5-hydroxytryptamine 2c receptor subtype superagonist, in development for the potential treatment of developmental and epileptic encephalopathies. Longboard is also evaluating LP143, a centrally acting, full cannabinoid type 2 receptor agonist, in development for the potential treatment of neurodegenerative diseases associated with neuroinflammation caused by microglial activation, and LP659, a centrally acting, sphingosine-1-phosphate receptor subtypes 1 and 5 modulator, in development for the potential treatment of central nervous system neuroinflammatory diseases.
