Background:

SAGE-217 is a potent GABAA receptor agonist with EC50s of 296 and 163 nM for α1β2γ2 and α4β3δ GABAA receptors, respectively.

Kinase assay demonstrates that SAGE-217 is a potent GABAA receptor agonist with EC50s of 296 and 163 nM for α1β2γ2 and α4β3δ GABAA receptors, respectively. SAGE-217 is currently being studied in parallel phase 2 clinical trials for the treatment of postpartum depression (PPD) and major depressive disorder (MDD). SAGE-217 shows >30 uM inhibition in a cardiac panel of eight relevant cardiac ion channels. At 10 uM concentration of SAGE-217, only binding at the glycine (57%), sigma receptors (88%), and inhibition of the transient receptor potential vanilloid 1 (TRPV1, 95%) is noted[1].

Acute administration of SAGE-217 (0.3 to 10 mg/kg, ip) effectively reduces pentylenetretazol (PTZ)-induced seizures in mice (MECplasma=85 nM) as well as produces a dose-dependent anticonvulsant effect in the mouse 6 Hz electrical stimulation model. In the rat lithium-pilocarpine model of status epilepticus (SE), SAGE-217 (0.3 to 5 mg, iv) abolishes both behavioral and electrographic seizure activity, even when administered 60 min after induction of SE. Additional PK studies of SAGE-217 in dog show low clearance (<10% of hepatic blood flow), resulting in excellent oral bioavailability (F=68%)[1].
