The purpose of this study is to assess the anti-tumor activity of amivantamab as a monotherapy (Cohorts A, B, and C), to assess the recommended phase 2 combination dose (RP2CD) of amivantamab when added to SoC chemotherapy (Ph1b cohorts) and to characterize the safety of amivantamab when added to standard-of care (SoC) chemotherapy in participants with metastatic colorectal cancer (mCRC) (Ph2 cohorts).
Colorectal cancer (CRC) is a major global health concern and the third most common cancer worldwide. Amivantamab (also known as RYBREVANT or JNJ-61186372) is a fully human immunoglobulin (Ig) G1-based bispecific antibody (Ab) directed against the epidermal growth factor (EGF) and mesenchymal epithelial transition (MET) receptors, with evidence of preclinical activity against non-small cell lung cancer (NSCLC) tumors with activating EGF receptor (EGFR) mutations, the T790M and C797S second-site resistance EGFR mutations, overexpressed wild-type EGFR, as well as with activation of the MET pathway. Amivantamab has demonstrated activity in both EGFR- and MET-driven NSCLC, with preclinical evidence demonstrating its ability to recruit immune effector cells. While two anti-EGFR antibodies are incorporated as part of the SoC for CRC patients, MET is highly expressed or amplified in subsets of CRC and additionally plays a role in mediating resistance to anti-EGFR treatments. The study consists of up to 28 days screening period, treatment period will begin on Cycle 1 Day 1 (C1D1) (for Cohorts A, B, and C) or C1D -2 (for Ph1b-D, Ph1b-E, Cohorts D, E and F) with the administration of the study treatment and continue as 28-day cycles until the end of treatment visit, up to 30 days after discontinuation of study treatment. The safety of amivantamab as a monotherapy or in addition to SoC chemotherapy will be assessed by physical examinations, Eastern Cooperative Oncology Group (ECOG) criteria for performance status (PS), laboratory tests, vital signs, monitoring of adverse events, and concomitant medication usage.
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Participant must have tumor previously characterized as having wild-type Kirsten rat sarcoma viral oncogene (KRAS), neuroblastoma RAS viral oncogene homolog (NRAS), v-raf murine sarcoma viral oncogene homolog B (BRAF), and without evidence of Erb-b2 receptor tyrosine kinase 2/human epidermal growth factor receptor 2 (/HER2) amplification.

Exclusion Criteria:
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).
Your pathology report is the document that shows this.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
HER2 is a protein, made from the ERBB2 gene, that drives the growth of some cancers. A study may look for a level of the protein, extra copies of the gene, or a particular change in it.
In breast cancer, protein tests are read as HER2-positive, HER2-low or HER2-negative; other cancers use their own rules. Check which test result the study requires.
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.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
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.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
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.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).
Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.
Cancer that has spread to the leptomeninges, the thin layers covering the brain and spinal cord, and the fluid between them. It is not the same as brain metastases.
Criteria often treat it separately, and many studies leave it out even where treated brain metastases are allowed.

Started Jul 2022 (actual). Primary completion is estimated for Apr 2027, 56 months after the start.
Of 158 industry-sponsored phase 1/2 interventional studies under Colorectal Neoplasms, half reached primary completion within 59 months of starting (the median), counting those still running; a quarter within 41 and three quarters within 82. This study's planned 56 months is close to that.
Counting every sponsor, half of 260 studies reached it within 59 months; a quarter within 36 and three quarters within 87.
Completion moved once since we started tracking on Sep 25, 2026: Oct 2030 → May 2031, on Sep 25, 2026.
