Researchers are looking for other ways to treat locally advanced or metastatic colorectal cancer (mCRC) that is unresectable and has a gene mutation called KRAS G12C.
Standard (or usual) treatments for this type of colorectal cancer may include mFOLFOX6 with or without bevacizumab. Researchers want to learn if adding MK-1084 (the study medicine) and cetuximab to mFOLFOX6 can treat locally advanced or mCRC with the KRAS G12C mutation. MK-1084 and cetuximab are targeted therapies.
The goals of this study are to learn:
* About the safety of MK-1084 with cetuximab and mFOLFOX6 and if people tolerate the treatments
* If people who receive MK-1084 with cetuximab and mFOLFOX6 live longer without mCRC growing or spreading compared to people who receive mFOLFOX6 with or without bevacizumab.
