A PHASE 2, RANDOMIZED, OPEN-LABEL STUDY OF ENCORAFENIB AND CETUXIMAB PLUS PEMBROLIZUMAB VERSUS PEMBROLIZUMAB ALONE IN PARTICIPANTS WITH PREVIOUSLY UNTREATED BRAF V600E-MUTANT, MSI H/DMMR METASTATIC COLORECTAL CANCER
Description
Brief Summary
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.
