SRK-181 is under clinical development by Scholar Rock and currently in Phase I for Oropharyngeal Cancer. According to GlobalData, Phase I drugs for Oropharyngeal Cancer have an 81% phase transition success rate (PTSR) indication benchmark for progressing into Phase II. GlobalData’s report assesses how SRK-181’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.

SRK-181 overview

SRK-181 is under development for the treatment of solid tumors including but not limited to bladder cancer, myelofibrosis, urothelial cancer, non-small cell lung cancer, melanoma, clear cell renal cell carcinoma (ccRCC), myelofibrosis , breast cancer and ovarian cancer and oropharyngeal cancer. It acts by targeting transforming growth factor beta 1 (TGFB1). The drug candidate is developed using the supracellular activation technology platform.

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.
