Summary
This study is being done to find out if tucatinib with other cancer drugs works better
than standard of care to treat participants with HER2 positive colorectal cancer. This
study will also test what side effects happen when participants take this combination of
drugs. A side effect is anything a drug does to the body besides treating your disease.
Participants in this study have colorectal cancer that has spread through the body
(metastatic) and/or cannot be removed with surgery (unresectable).
Participants will be assigned randomly to the tucatinib group or standard of care group.
The tucatinib group will get tucatinib, trastuzumab, and mFOLFOX6. The standard of care
group will get either:
- mFOLFOX6 alone,
- mFOLFOX6 with bevacizumab, or
- mFOLFOX6 with cetuximab mFOLFOX6 is a combination of multiple drugs. All of the
drugs given in this study are used to treat this type of cancer.
Eligibility
- Histologically and/or cytologically confirmed adenocarcinoma of the colon or rectum which is locally advanced unresectable or metastatic
- Able to provide the most recently available formalin-fixed paraffin-embedded (FFPE) tumor tissue blocks (or freshly sectioned slides) obtained prior to treatment initiation to a central laboratory
- If archival tissue is not available, a newly-obtained baseline biopsy of an accessible tumor lesion is required within 35 days prior to start of study treatment
- HER2+ disease as determined by a tissue based assay performed at a central laboratory.
- Participant has rat sarcoma viral oncogene homolog wild-type (RAS WT) disease as determined by local or central testing. For central RAS analysis, tissue sample must be analyzed within 1 year of biopsy date.
- Radiographically measurable disease per RECIST v1.1 with:
- At least one site of disease that is measurable and that has not been previously irradiated, or
- If the participant has had previous radiation to the target lesion(s), there must be evidence of progression since the radiation
- Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
- CNS Inclusion - based on contrast brain magnetic resonance imaging, participants may have any of the following:
- No evidence of brain metastases
- Previously treated brain metastases which are asymptomatic

**Clinical trials are research studies that involve people. These studies test new ways to prevent, detect, diagnose, or treat diseases. People who take part in cancer clinical trials have an opportunity to contribute to scientists’ knowledge about cancer and to help in the development of improved cancer treatments. They also receive state-of-the-art care from cancer experts...
