Mepolizumab is under clinical development by GSK and currently in Phase III for Chronic Obstructive Pulmonary Disease (COPD). According to GlobalData, Phase III drugs for Chronic Obstructive Pulmonary Disease (COPD) have a 63% phase transition success rate (PTSR) indication benchmark for progressing into Pre-Registration. GlobalData’s report assesses how Mepolizumab’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.
