About
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 calderasib (the study medicine) and cetuximab to mFOLFOX6 can treat locally advanced or mCRC with the KRAS G12C mutation. Calderasib and cetuximab are targeted therapies.
The goals of this study are to learn:
- About the safety of calderasib with cetuximab and mFOLFOX6 and if people tolerate the treatments
- If people who receive calderasib with cetuximab and mFOLFOX6 live longer without mCRC growing or spreading compared to people who receive mFOLFOX6 with or without bevacizumab.

This study will have 2 parts.
