In tumours with faulty DNA repair, adding olaparib to bevacizumab maintenance roughly doubled progression-free time and improved survival.
In newly diagnosed advanced ovarian cancer with homologous recombination deficiency, adding the PARP inhibitor olaparib to bevacizumab maintenance is a combination pairing that markedly prolonged progression-free time and improved overall survival in the phase 3 PAOLA-1 / ENGOT-ov25 trial, with no benefit seen in HRD-negative tumours. The mechanistic rationale is that anti-angiogenic hypoxia may push tumour cells into HRD-like states and greater dependence on PARP, and the two agents have non-overlapping toxicity. The combination was approved in 2020. Because the benefit was confined to the HRD-positive subgroup, the pairing made HRD testing a routine first-line decision in ovarian cancer.
