Arm | Intervention/treatment |
---|---|
Experimental: Arm A (regorafenib)
Patients receive regorafenib PO QD on days 1-21. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. If received as initial treatment, patients who experience disease progression may switch over to the other treatment regimen, per treating physician discretion.

Experimental: Arm B (cetuximab, panitumumab, irinotecan)
Patients receive cetuximab or panitumumab IV over 30-90 minutes on days 1 and 15. Patients may also receive irinotecan IV on days 1 and 15 as determined by the study doctor. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
