Clinical Trial of an Anti-cancer Drug, CA-4948 (Emavusertib), in Combination With Chemotherapy Treatment (FOLFOX Plus Bevacizumab) in Metastatic Colorectal Cancer

This phase I trial studies the side effects and best dose of CA-4948 when given together with fluorouracil, leucovorin, oxaliplatin (FOLFOX) plus bevacizumab in treating patients with colorectal cancer that has spread from where it first started (primary site) to other places in the body (metastatic). CA-4948 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. The chemotherapy drugs used in FOLOX, fluorouracil and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Leucovorin is used with fluorouracil to treat colorectal cancer. Bevacizumab is in a class of medications called anti-angiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to the tumor. This may slow the growth and spread of the tumor. Giving CA-4948 with FOLFOX plus bevacizumab may be safe, tolerable and/or effective in treating patients with metastatic colorectal cancer.

The effects of CA-4948 (emavusertib) on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation.

Pregnant women are excluded from this study because CA-4948 (emavusertib) is a blood-brain barrier penetrant with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with CA-4948 (emavusertib), breastfeeding should be discontinued if the mother is treated with CA-4948 (emavusertib). These potential risks may also apply to other agents used in this study. Women of childbearing potential must have a negative pregnancy test within 7 days of study entry
