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.

A2A-04 overview

A2A-04 is under development for the treatment of solid tumor, leukemia, triple-negative breast cancer (TNBC), high-grade serous ovarian carcinoma (HGSOC), primary peritoneal cancer, fallopian tube cancer and endometrial cancer. It acts by targeting the stimulator of interferon genes protein (STING). The drug candidate is developed based on Systematic Combinatorial Unification of chemical groups into Libraries against a Pharmacological Target (SCULPT) therapeutic design platform. It is administered through oral route.
