Pamrevlumab is under clinical development by FibroGen and currently in Phase III for Duchenne Muscular Dystrophy. According to GlobalData, Phase III drugs for Duchenne Muscular Dystrophy have a 62% phase transition success rate (PTSR) indication benchmark for progressing into Pre-Registration. GlobalData’s report assesses how Pamrevlumab’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.

Pamrevlumab overview

Pamrevlumab (FG-3019) is under development for the treatment of idiopathic pulmonary fibrosis, Duchenne muscular dystrophy and metastatic pancreatic ductal adenocarcinoma (PDAC) or fibrosis involved in pancreatic cancer, liver fibrosis and coronavirus disease 2019 caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It is administered as an intravenous infusion. FG-3019 is a fully human recombinant IgG, kappa monoclonal antibody that acts against connective tissue growth factor (CTGF). The drug candidate was also under development for the treatment of systemic sclerosis, microalbuminuria, pneumonia, focal segmental glomerulosclerosis, type I or type II diabetes mellitus, diabetic nephropathy,  (diabetic kidney disease) and proteinuria.

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.
