The purpose of this study is to evaluate the efficacy and toxicity of FOLFOX regimen with dabrafenib and cetuximab/panitumumab in the first line of therapy for the potential treatment of colorectal cancer that: has a metastatic, inoperable; has a mutation in the BRAF gene and MSS.
Participants in this study will receive one of the following study treatments:
These participants will receive FOLFOX regimen with dabrafenib and cetuximab or panitumumab in the first line of therapy This study is currently enrolling participants who will receive either FOLFOX regimen with dabrafenib and cetuximab or panitumumab in the first line of therapy.
The study team will monitor how each participant responds to the study treatment for up to about 3 years.
The purpose of the study is to evaluate the efficacy and toxicity of first-line FOLFOX with dabrafenib and cetuximab or panitumumab in patients with previously untreated metastatic inoperable colorectal cancer who have MSS and BRAF mutation.
6,541 studies on the registry are indexed under Colorectal Neoplasms; 1,667 are open to participants now.
This study's planned enrollment of 64 is below the median of 76 across 4,800 interventional studies indexed under Colorectal Neoplasms.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.
“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.
Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.
“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
Able to have children. For women this usually means from the first period until menopause, unless permanently unable to through surgery; for men, unless permanently sterile. Read who the line is about — participants, women, men, or their partners.
Criteria about it usually ask for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Started Mar 2025 (actual). Primary completion is estimated for Nov 2027, 32 months after the start.
Of 498 non-industry phase 2 interventional studies under Colorectal Neoplasms, half reached primary completion within 55 months of starting (the median), counting those still running; a quarter within 33 and three quarters within 75. This study's planned 32 months is below that.
Counting every sponsor, half of 618 studies reached it within 49 months; a quarter within 31 and three quarters within 75.
