Efgartigimod alfa is under clinical development by Argenx and currently in Phase III for Pemphigus Vulgaris. According to GlobalData, Phase III drugs for Pemphigus Vulgaris have a 25% phase transition success rate (PTSR) indication benchmark for progressing into Pre-Registration. GlobalData’s report assesses how Efgartigimod alfa’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.
