Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to find out whether combining nivolumab, FOLFOX, and regorafenib may be a safe and effective treatment for people who have HER2-negative metastatic esophagogastric cancer.

Nivolumab is an antibody, like the proteins made by the immune system to protect the body from harm. Nivolumab blocks the protein PD-1 (programmed cell death receptor-1) that usually acts as a "brake" on the immune system. Blocking this protein is like releasing the brakes, so that the immune system can target cancer cells and destroy them.

FOLFOX is a combination of three standard chemotherapy drugs (leucovorin, 5-fluorouracil, and oxaliplatin) commonly used to treat your type of cancer. The drugs work by damaging the DNA in cancer cells, which can cause the cells to stop growing and die.

Regorafenib is a type of drug called a tyrosine kinase inhibitor (TKI). This drug targets the tyrosine kinase protein found in or on the surface of cancer cells that the cells need to survive and grow. Blocking this protein may stop cancer cells from growing, or cause them to grow more slowly or to shrink.

The study researchers think that combining nivolumab, FOLFOX, and regorafenib may be a more effective treatment for HER2-negative metastatic esophagogastric cancer than the usual chemotherapy treatment(s) alone.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Nivolumab Combined With FOLFOX and Regorafenib

Each treatment cycle consists of 28 days. Patients will initially receive induction therapy with regorafenib (80 mg on days 1-21 of the 28-day cycle) and nivolumab (240 mg on days 1 and 15 of the 28-day cycle). Starting on cycle 2, day 1, patients will also receive FOLFOX chemotherapy with oxaliplatin (85 mg/m2 IV), leucovorin (400 mg/m2 IV), 5-FU (400 mg/m2 IV bolus), and 5-FU (2400 mg/m2/day continuous IV infusion over 48 h). If the patient is not a good candidate for induction regorafenib and nivolumab (i.e. symptomatic from a large burden of disease), 5-FU and oxaliplatin can be added during cycle 1 at the treating physician's discretion. 39 Patients will continue with this regimen until disease progression, unacceptable toxicity, or development of serious intercurrent illness. Treatment will be performed on the scheduled day (±7-day treatment window).
