- To assess the efficacy of olaparib combined to metronomic cyclophosphamide and metformin in patients with advanced/metastatic endometrial carcinomas; - To assess the safety of the combination throughout the study; - To obtain data on the respective pharmacodynamic effects of the 3 drugs on involved signaling pathways (PI3K-AKT-mTor-S6K; PARP1 and IGF1R in PBMCs, tumor samples and in baseline blood samples) along with potential pharmacodynamic interactions; - To obtain data on the kinetics of circulating pharmacodynamic biomarkers, including CA-125, IGF-1, insulin and circulating tumor DNA, to be related with treatments effects; - To obtain data about impact of DNA damage repair system alterations on treatment effects: homologous recombination, Lynch syndrome and other DNA repair genes.
