Phase I/II clinical trial - Gynécologie - Endomètre

Endometrial carcinomas are characterized by frequent alterations of PI3K-AKT-mTor; IGF1R and of DNA repair pathways. Phosphatase and tensin homologue (PTEN)-phosphoinositide 3-kinase (PI3K)-mammalian target of rapamycin (mTor) and DNA repair pathways interact, and inhibition of PI3K-AKT-mTor signaling pathway may alter DNA damage repair.;Metronomic cyclophosphamide regimen may increase the anti-proliferative effects of olaparib because it is an alkylating agent, and it exerts anti-angiogenic effects, with a favorable toxicity profile.;Metformin may increase the anti-proliferative effects of olaparib because it downregulates IGF1R and PI3K-AKT-mTor pathways, with no additive toxicity.;The purpose of this study is to assess the safety profile and the recommanded dose of olaparib combined to metronomic cyclophosphamide and metformine for further phase II clinical trials.
