Zuranolone is under clinical development by Sage Therapeutics and currently in Phase II for Treatment Resistant Depression. According to GlobalData, Phase II drugs for Treatment Resistant Depression have a 35% phase transition success rate (PTSR) indication benchmark for progressing into Phase III. GlobalData’s report assesses how Zuranolone’s drug-specific PTSR and Likelihood of Approval (LoA) scores compare to the indication benchmarks. Buy the report here.

GlobalData tracks drug-specific phase transition and likelihood of approval scores, in addition to indication benchmarks based off 18 years of historical drug development data. Attributes of the drug, company and its clinical trials play a fundamental role in drug-specific PTSR and likelihood of approval.

Zuranolone overview

Zuranolone (Zurzuvae) is a neuroactive steroid gamma-aminobutyric acid (GABA) positive modulator receptor. It is formulated as capsules for the oral route of administration. Zurzuvae is indicated for the treatment of postpartum depression (PPD) in adults.

Zuranolone (SAGE-217, SAGE-NCE) is under development for the treatment of postpartum depression, bipolar depression, major depressive disorder, treatment resistant depression and generalized anxiety disorder. It is administered through oral route in the form of capsule or solution. It is a new chemical entity (NCE) that targets GABAA receptor. SAGE-NCE is developed based on positive and negative allosteric modulator (PANAM) chemistry platform.

It was also under development as an intravenous therapy for refractory status epilepticus (RSE) and as an oral therapy for orphan genetic epilepsy disorders, such as Dravet syndrome, Rett syndrome and Fragile X syndromes. The drug candidate was also under development for essential tremors, dyskinesias, insomnia and Parkinson’s disease.
