Irinotecan and Cetuximab With or Without Bevacizumab in Treating Patients With RAS Wild-Type Locally Advanced or Metastatic Colorectal Cancer That Cannot Be Removed by Surgery

Colorectal Adenocarcinoma Clinical Trial

Official title: BOND-3: A Randomized, Double-Blind, Placebo-Controlled Phase II Trial of Irinotecan, Cetuximab, and Bevacizumab Compared With Irinotecan, Cetuximab, and Placebo in RAS-Wildtype, Irinotecan-Refractory, Metastatic Colorectal Cancer

Status Completed

Clinical Trial Summary

This randomized phase II trial studies how well irinotecan and cetuximab with or without bevacizumab work in treating patients with RAS wild-type colorectal cancer that has spread to other places in the body (locally advanced/metastatic) and cannot be removed by surgery. Irinotecan may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as cetuximab and bevacizumab, may help the body?s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving irinotecan and cetuximab with or without bevacizumab may work betting in treating patients with colorectal cancer.

Clinical Trial Description

PRIMARY OBJECTIVES:

I. To assess and compare the progression-free survival (PFS) of patients receiving irinotecan, cetuximab, and bevacizumab with patients receiving irinotecan, cetuximab and placebo, in the population of patients with RAS wild-type, irinotecan-refractory metastatic colorectal cancer (mCRC) who also previously received bevacizumab in at least one prior line therapy.

SECONDARY OBJECTIVES:

I. To assess the adverse event (AE) profile and safety of the proposed treatment in this population.

II. To assess and compare the overall survival (OS) between treatment arms in this population.

III. To assess and compare the disease control rate (DCR) between treatment arms in this population.

IV. To assess and compare the overall response rate (ORR) between treatment arms in this population.

V. To assess and compare the duration of response between treatment arms in this population.

VI. To assess and compare time to treatment failure between treatment arms in this population.

VII. To assess relative dose intensity of treatment agents between treatment arms in this population.

CORRELATIVE OBJECTIVES:

I. Determine the change in genotype concentrations of prespecified gene mutations in circulating cell-free deoxyribonucleic acid (DNA) (cfDNA) collected serially during protocol treatment.

II. Explore the predictive value of pretreatment mutation status, germline single nucleotide polymorphisms (SNPs), and gene expression signatures for cetuximab sensitivity and resistance.

III. Explore the predictive value of dynamic changes in mutation status and gene expression signatures for cetuximab sensitivity and resistance.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive cetuximab intravenously (IV) over 90-120 minutes, bevacizumab IV over 30-90 minutes, and irinotecan IV over 90 minutes on day 1. Cycles repeat every 14 days in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive cetuximab IV over 90-120 minutes, placebo IV over 30-90 minutes, and irinotecan IV over 90 minutes on day 1. Cycles repeat every 14 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for up to 2 years. ;
