Summary

This trial is testing a combination of drugs to treat stomach or intestinal cancer. The first drug, BAY 1895344, may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. The second drug, a chemotherapy drug called FOLFIRI, works 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. The trial is testing to see if the combination of these two drugs may help shrink advanced or metastatic stomach and/or intestinal cancer.

Who is the study for?
Adults with advanced or metastatic stomach/intestinal cancer who've progressed after first-line therapy can join. They must have adequate organ function, no severe reactions to similar drugs, and agree to use contraception. Those with certain viral infections must be stable on treatment without interactions.
What is being tested?
The trial is testing BAY 1895344 combined with FOLFIRI chemotherapy against cancers of the stomach and intestines. It aims to find the best dose and assess benefits/side effects by seeing if this combination can shrink tumors more effectively than standard treatments.
What are the potential side effects?
Possible side effects include typical chemotherapy-related issues like fatigue, digestive problems, blood cell count changes, as well as potential drug-specific effects such as allergic reactions or enzyme inhibition that could affect cell growth.

Experimental Treatment
Group I: Treatment (elimusertib, FOLFIRI)Experimental Treatment7 Interventions
Patients receive elimusertib PO QD on days 2, 3, 16, and 17 and irinotecan hydrochloride IV over 90 minutes, fluorouracil IV over 46 hours, and leucovorin calcium IV on days 1 and 15. Cycles repeat every 28 day in the absence of disease progression or unacceptable toxicity. Patients undergo tumor biopsy during screening and on study and blood sample collection and imaging throughout the study.
