Dexpramipexole dihydrochloride is under clinical development by Areteia Therapeutics and currently in Phase II for Hypereosinophilic Syndrome. According to GlobalData, Phase II drugs for Hypereosinophilic Syndrome have an 80% phase transition success rate (PTSR) indication benchmark for progressing into Phase III. GlobalData’s report assesses how Dexpramipexole dihydrochloride’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.

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.
