Mechanism of action

PARP inhibitors block the repair of single-strand DNA breaks. In cells with BRCA1/2 mutations (deficient in homologous recombination repair), this leads to accumulation of DNA damage and synthetic lethality. Olaparib is effective in cancers with homologous recombination deficiency, including BRCA-mutant and other HRD-positive tumors.
