Abstract

TPS264 Background: TALA is a poly(ADP-ribose) polymerase (PARP) inhibitor that inhibits PARP1/2 and traps PARP on DNA, preventing DNA damage repair (DDR) and causing death of cells with DDR mutations (eg BRCA1/2). TALA is approved in multiple countries for germline BRCA1/2-mutated HER2- advanced breast cancer. ENZA is an established therapy for CRPC. PARP1 activity has been shown to support AR function, suggesting that co-blockade of PARP1 may synergize with AR-directed therapy, regardless of DDR deficiency. A combination of TALA with ENZA in mCRPC may improve clinical outcomes in patients with or without DDR-deficient tumors. TALAPRO-2 (NCT03395197) is a 2-part study to evaluate efficacy, ..
