New hope for colorectal cancer: amivantamab plus chemotherapy in clinical trial

NCT ID NCT05379595

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study is testing a drug called amivantamab, either alone or with standard chemotherapy, in people with advanced or metastatic colorectal cancer. The goal is to see if the combination can shrink tumors and to find the safest dose. About 225 participants will take part across multiple groups.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
amivantamab (RYBREVANT) and standard chemotherapy drugs (fluorouracil, leucovorin, oxaliplatin, irinotecan)
What this could lead to
If it works, this could offer a new treatment option for people with advanced colorectal cancer that hasn't responded to other therapies.
What could go wrong
This is an early-phase trial (phase 1b/2), so it's still testing safety and the right dose. It may not work for everyone, and side effects could be serious.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Participant must have been previously diagnosed with histologically or cytologically confirmed unresectable or metastatic adenocarcinoma of the colon or rectum * 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 (ERBB2/HER2) amplification. Additional cohort-specific requirements: * Phase (Ph) 2 (Cohorts A, B, and C) Amivantamab monotherapy: Participant must have received at least 2 but not more than 3 prior lines of systemic therapy in the metastatic setting. Participant must have been diagnosed with left-sided colorectal cancer (CRC) (Cohort A and B) and right-sided (Cohort C)and have received or been intolerant to standard of care (SoC) fluoropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapy and an anti-vascular endothelial growth factor (VEGF) treatment. Participant must be anti-EGFR treatment naive in Cohort A, an anti-epidermal growth factor receptor (EGFR) treatment Cohort B, with or without an anti-EGFR treatment in Cohort C * Ph 1b Dose Confirmation Cohorts (Ph1b-D and Ph1b-E), Ph2 (Cohorts D and E) Amivantamab+mFOLFOX6/FOLFIRI: Participant must been diagnosed with CRC and have received no more than 1 prior line of systemic therapy in the metastatic setting. Cohort Ph1b-D/Cohort D: Participant must be anti-EGFR treatment naïve, have not received oxaliplatin-based chemotherapy in the metastatic setting, and be eligible for treatment with mFOLFOX6 according to local regulatory approvals and SoC guidelines. Cohort Ph1b-E/Cohort E: Participant must be anti-EGFR treatment naïve, have not received irinotecan-based chemotherapy in the metastatic setting, and be eligible for treatment with FOLFIRI according to local regulatory approvals and SoC guidelines * Ph2 Cohorts F Amivantamab subcutaneous (SC) + mFOLFOX6: Participants must be treatment-naive for right-sided unresectable or metastatic CRC and be eligible for treatment with mFOLFOX6 according to local regulatory approvals and SoC guidelines * For Phase 1 dose confirmation cohorts (Cohorts Ph1b-D and Ph1b-E): Participant must have evaluable disease. For Phase 2: Participant must have measurable disease according to Response Criteria in Solid Tumors (RECIST) Version 1.1. If only one measurable lesion exists, it may be used for the screening biopsy as long as baseline tumor assessment scans are performed greater than or equal to (\>=) 7 days after the biopsy * Participant must have Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1 * Participant must have a tumor lesion amenable for biopsy and agree to mandatory protocol-defined screening biopsy. Biopsies are required if clinically feasible for participants in Ph1b-D, Ph1b-E, and Cohort F. For Cohort F, archival tissue is required if a fresh biopsy is not feasible * A female participant of childbearing potential must have a negative serum pregnancy test at screening and within 72 hours of the first dose of study treatment and must agree to further serum or urine pregnancy tests during the study. Note: Participant must not be pregnant, breastfeeding, or planning to become pregnant while enrolled in this study Exclusion Criteria: * Cohorts A, B, C, Ph1b-D, D, Ph1b-E, and E: Participant with identified mutation in Kirsten rat sarcoma viral oncogene (KRAS), neuroblastoma RAS viral oncogene homolog (NRAS), v-raf murine sarcoma viral oncogene homolog B (BRAF), or epidermal growth factor receptor (EGFR) ectodomain, or ERBB2/HER2 amplification by central circulating tumor deoxyribonucleic acid (ctDNA) testing at screening; Cohort F: Participant with identified mutation in KRAS, NRAS, BRAF V600, or PTEN, identified fusions in ALK, ROS-1, RET, and NTRK 1, ERBB2/HER2 amplification, or identified to have MSI-H status by central ctDNA testing at screening * Participant with symptomatic or untreated brain metastasis * History or known presence of leptomeningeal disease * Any condition for which, in the opinion of the investigator, participation would not be in the best interest of the participant (for example, compromise the well-being) or that could prevent, limit, or confound the protocol-specified assessments
