PRT-543 is under clinical development by Prelude Therapeutics and currently in Phase I for Ovarian Cancer. According to GlobalData, Phase I drugs for Ovarian Cancer have a 74% phase transition success rate (PTSR) indication benchmark for progressing into Phase II. GlobalData’s report assesses how PRT-543’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.

PRT-543 overview

PRT-543 is under development for the treatment of relapsed/refractory solid tumors like HRD+ high grade serous ovarian cancer, breast cancer, head and neck cancer bladder cancer, small cell lung cancer and hematological malignancies like diffuse large B-cell lymphoma, mantle cell lymphoma, myelodysplastic syndrome, refractory acute myeloid leukemia, chronic myelomonocytic leukemia and myelofibrosis. The drug candidate is administered through oral route. It acts by targeting the protein arginine N methyltransferase 5 (PRMT5).

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.
