Empasiprubart is under clinical development by Argenx and currently in Phase II for Multifocal Motor Neuropathy. According to GlobalData, Phase II drugs for Multifocal Motor Neuropathy have a 100% phase transition success rate (PTSR) indication benchmark for progressing into Phase III. GlobalData’s report assesses how Empasiprubart’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.
