Olaparib combined to metronomic cyclophosphamide and metformin in women with recurrent advanced/metastatic endometrial cancer: the ENDOLA phase I/II trial.

ABSTRACT: Endometrial cancers are characterized by frequent alterations in the PI3K-AKT-mTor, IGF1 and DNA repair signaling pathways. Concomitant inhibition of these pathways was warranted. ENDOLA phase I/II trial (NCT02755844) was designed to assess the safety/efficacy of the triplet combination of the PARP inhibitor olaparib, metronomic cyclophosphamide (50 mg daily), and PI3K-AKT-mTor inhibitor metformin (1500 mg daily) in women with recurrent endometrial carcinomas. Olaparib dose-escalation (100-300 mg twice-a-day (bid)) was used to determine the recommended-phase II-trial-dose (RP2D, primary endpoint), followed by an expansion cohort to determine the non-progression rate at 10 weeks (NPR-10w, secondary endpoint). 31 patients were treated. Olaparib RP2D was defined as 300 mg bid. The tolerabilit
