Animal experiment: | In vivo pharmacokinetic parameters are determined in male Sprague Dawley rats (of 200 to 300 g in weight), male CD-1 mice (15 to 25 g in weight), and male beagle dogs (8 to 12 kg in weight). Doses of Zuranolone (SAGE-217) for intravenous (IV) and oral administration (PO) are formulated as solutions in SBECD. Zuranolone (SAGE-217) is dosed IV (5 mg/kg, 2.5 mL/kg) or by oral gavage (20 mg/kg, 10 mL/kg). Animals in the IV group are sampled at 0.083, 0.25, 1, 2, 4, and 8 hours post-dose and PO animals are sampled at 0.5, 1, 2, 4, and 8 hours post dose. Brain samples from the IV group are also collected at 1 hour post-dose. Blood samples are collected into tubes treated with K2-EDTA, then centrifuged at 2000 g at 4°C for 15 min. Plasma is isolated and frozen at -70°C until extraction[1]. |

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].
