ADPA-2M4CD8 is under clinical development by Adaptimmune Therapeutics 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 ADPA-2M4CD8’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.

ADPA-2M4CD8 overview

ADP-A2M4CD8 is under development for the treatment of solid tumors including platinum-resistant ovarian cancer, urothelial carcinoma, endometrial cancer, esophageal cancer, melanoma, esophagogastric junction (EGJ) cancer, gastric cancer, non-small cell lung carcinoma (NSCLC), peritoneal cancer, fallopian tube cancer and head and neck cancer. The therapeutic candidate comprises of CD8 alpha co-receptor alongside the autologous genetically modified engineered TCR that targets MAGE-A4. It is a next-generation of ADP-A2M4 which is administered by parenteral route. It is developed based on SPEAR T-cell platform.

It was under development for synovial sarcoma, myxoid, round cell liposarcoma and bladder cancer.

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.
