Idelalisib is under clinical development by Gilead Sciences and currently in Phase II for Diffuse Large B-Cell Lymphoma. According to GlobalData, Phase II drugs for Diffuse Large B-Cell Lymphoma have a 40% phase transition success rate (PTSR) indication benchmark for progressing into Phase III. GlobalData’s report assesses how Idelalisib’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.

Idelalisib overview

Idelalisib (Zydelig) drug belongs to anti-neoplastic agent. It is formulated as film-coated tablets for oral route of administration.
