ATA-2271 is under clinical development by Atara Biotherapeutics and currently in Phase I for Malignant Pleural Mesothelioma. According to GlobalData, Phase I drugs for Malignant Pleural Mesothelioma have an 80% phase transition success rate (PTSR) indication benchmark for progressing into Phase II. GlobalData’s report assesses how ATA-2271’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.
