Detailed Summary

This phase I trial tests the safety, side effects and best dose of peposertib (M3814) in combination with tuvusertib (M1774) in treating patients with solid tumors that have spread to other places in the body (advanced). Peposertib and tuvusertib stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Arms & Interventions

Treatment (peposertib, tuvusertib)experimental

Patients receive peposertib PO QD or BID daily on days 2-14 of cycle 1 and days 1-14 of subsequent cycles in combination with tuvusertib PO QD daily on days 1-14 of each cycle. Cycles repeat every 28 days in the absence of disease progression, pregnancy, non-compliance, unacceptable toxicity, termination of the study or the study drug is no longer available. Patients also undergo tumor biopsy, blood sample collection, PET, CT, and MRI throughout the study.
