Synergy was demonstrated in a combination arm of GLIX1 and the PARP inhibitor olaparib at low doses, with substantially better efficacy compared to the control arm and compared to each drug individually at its optimal doseGLIX1 in combination with olaparib also showed comparable efficacy to that seen with the chemotherapy drug cisplatin Results reinforce synthetic lethality between GLIX1 and PARP inhibitors, indicating that GLIX1 can broaden the use of PARPi in ovarian cancerÂ
