Summary

This phase I trial studies the side effects and best dose of adavosertib when given together with olaparib in treating patients with solid tumors that have spread to other places in the body (advanced) with selected mutations. Adavosertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. PARPs are proteins that help repair DNA mutations. PARP inhibitors, such as olaparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing. Giving olaparib and adavosertib one after the other may shrink or stabilize advanced solid tumors as successfully as using them together, with fewer side effects.
