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.
PRIMARY OBJECTIVES: I. To determine the safety and tolerability of peposertib (M3814) in combination with tuvusertib (M1774). (DOSE ESCALATION AND EXPANSION COHORT) II. To determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of the combination of peposertib (M3814) and tuvusertib (M1774). (DOSE ESCALATION COHORT) SECONDARY OBJECTIVES: I. To observe and record anti-tumor activity. II. To determine the pharmacokinetic (PK) profiles of peposertib (M3814) and tuvusertib (M1774) when administered in combination. EXPLORATORY OBJECTIVES: I. To explore correlations betwe…
Inclusion Criteria: * Patients must have histologically confirmed solid malignancy that is metastatic or unresectable and for which standard curative or palliative measures do not exist or are no longer effective, or if the treating investigator deems the study appropriate. * For the dose escalation and dose expansion phases, patients must have genomic (tumor next-generation sequencing \[NGS\], circulating tumor deoxyribonucleic acid \[ctDNA\], fluorescence in situ hybridization \[FISH\], etc.) or immunohistochemical evidence (e.g., loss of expression) of inactivating ATM mutations, MYC ampli…
