What is being tested
- Drug Encorafenib
- Biological Cetuximab
- Biological Pembrolizumab
What it is measuring
Progression-free Survival (PFS)
This is the trial's main question — the one it is designed and sized to answer. Anything else it reports is a secondary finding, and secondary findings are far more likely to be chance.
Phase 2. Tests whether the treatment works well enough to be worth a larger trial. Usually too small to prove it changes survival.
How the researchers describe it
The purpose of this study is to learn about the effects of three study medicines (encorafenib, cetuximab, and pembrolizumab) given together for the treatment of colorectal cancer that:
* is metastatic (spread to other parts of the body);
* has the condition of genetic hypermutability (tendency to mutation) or impaired DNA mismatch repair (MMR)
* has a certain type of abnormal gene called "BRAF" and;
* has not received prior treatment.All participants in this study will receive pembrolizumab at the study clinic as an intravenous (IV) infusion (given directly into a vein) at the study clinic.
In addition, half of the participants will take encorafenib by mouth at home every day and cetuximab by IV infusion at the study clinic.
The study team will monitor how each participant is doing with the study treatment during regular visits at the study clinic.

Who the trial is looking for
Inclusion Criteria
- Locally confirmed microsatellite instability-high/ deficient mismatch repair (MSI-H/dMMR) stage IV colorectal carcinoma
- Locally confirmed BRAF V600E mutation in tumor tissue or blood
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
- Have not received prior systemic regimens for metastatic disease.
- Measurable disease per RECIST 1.1
- Adequate organ function
Exclusion Criteria
- Colorectal adenocarcinoma that is RAS mutant or for which RAS mutation status is unknown
- Known active central nervous system metastases and/or carcinomatous meningitis; leptomeningeal disease

Where it is running
Running at 59 sites. Listed in: Australia, Belgium, Canada, Czechia, Denmark, France, Germany, Italy, Netherlands, Norway, Poland, Slovakia, Spain, United Kingdom, United States.
Individual hospitals, and whether each is currently open, are listed on the registry record. Sites open and close throughout a trial.
Worth asking your oncology team
Being listed here is not a recommendation, and no one page can tell you whether a trial is right for you. These are the questions it raises.
- Is this trial open at a hospital I could realistically travel to?
- Given my stage, my previous treatment and my tumour's molecular profile, would I be eligible?
- What would I be giving up by joining — is the comparison arm the treatment I would otherwise be having?
- What is already known about the safety of what is being tested?
