IMA-203 is under clinical development by Immatics and currently in Phase II for Ovarian Cancer. According to GlobalData, Phase II drugs for Ovarian Cancer have a 27% phase transition success rate (PTSR) indication benchmark for progressing into Phase III. GlobalData’s report assesses how IMA-203’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.

IMA-203 overview

IMA-203 is under development for the treatment of solid tumors include hepatocellular carcinoma ovarian cancer, endometrial cancer, uterine cancer, sqNSCLC, subtypes of synovial sarcoma, uveal melanoma. It is based on XPRESIDENT and ACTengine platform. XPRESIDENT is a target discovery engine which identifies tumor-associated peptides (TUMAPs) / T-cell targets. ACTengine platform uses autologous T-cells which are genetically engineered to express T-cell receptors upon lentiviral transduction which recognise targets identified by XPRESIDENT. These cells are expanded ex-vivo and reinfused back into the patient.It acts by targeting cells expressing preferentially expressed antigen in melanoma (PRAME).It is administered through intravenous route.

Immatics overview

Immatics is a biopharmaceutical company focused on the development of T cell immunotherapies to fight against cancer. Immatics is headquartered in Tuebingen, Germany.

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.
