SAGE-718 is under clinical development by Sage Therapeutics and currently in Phase II for Dementia Associated With Alzheimer’s Disease. According to GlobalData, Phase II drugs for Dementia Associated With Alzheimer’s Disease have a 67% phase transition success rate (PTSR) indication benchmark for progressing into Phase III. GlobalData’s report assesses how SAGE-718’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.

SAGE-718 overview

SAGE-718 is under development for the treatment of mild cognitive impairment (MCI) or mild dementia due to Alzheimer's disease (AD), Parkinson's disease mild cognitive impairment and Huntington disease. It is administered through oral route as a solution. SAGE-718 is a 24(S)-Hydroxycholesterol, that is a oxysterol-based positive allosteric modulator of NMDA receptor. It was also under development for anti-NMDA receptor encephalitis and cerebrosterol (24S-HC) deficit disorders such as Smith-Lemli-Opitz Syndrome (SLOS) and other indications involving NMDA receptor hypofunction.

GlobalData, the leading provider of industry intelligence, provided the underlying data, research, and analysis used to produce this article.

GlobalData’s Likelihood of Approval analytics tool dynamically assesses and predicts how likely a drug will move to the next stage in its clinical pathway (PTSR), as well as how likely the drug will be approved (LoA). This is based on a proprietary algorithm built from the drugs’ sales forecast, regulatory milestones, cost forecasts, WACC rate and other proprietary data sources found on GlobalData’s Pharmaceutical Intelligence Center.
