Treatment Arms

ArmTypeDescription
Dose escalation phase (zunsemetinib + mFOLFIRNOX)EXPERIMENTALThe dose of zunsemetinib will be determined by the dose level assigned and will be taken by mouth either once or twice daily depending on assigned dose level. mFOLFIRINOX will be 85 mg/m\^2 of oxaliplatin intravenous (IV) on day 1 of each cycle, 150 mg/m\^2 of irinotecan IV on day 1 of each cycle, 400 mg/m\^2 of leucovorin IV on day 1 of each cycle, and 2400 mg/m\^2 continuous infusion starting on day 1 of each cycle and continuing for 46 hours. Each cycle is 2 weeks in length.
Dose expansion phase (zunsemetinib + mFOLFIRNOX)EXPERIMENTALThe dose of zunsemetinib will be determined during the dose escalation phase of the trial. mFOLFIRINOX will be 85 mg/m\^2 of oxaliplatin intravenous (IV) on day 1 of each cycle, 150 mg/m\^2 of irinotecan IV on day 1 of each cycle, 400 mg/m\^2 of leucovorin IV on day 1 of each cycle, and 2400 mg/m\^2 continuous infusion starting on day 1 of each cycle and continuing for 46 hours.
