A Molecularly Driven Phase 1b Dose Escalation and Dose Expansion Study of the DNA-PK Inhibitor Peposertib (M3814) in Combination With the ATR Inhibitor Tuvusertib (M1774)
National Cancer Institute (NCI)
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.
Description
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…
