Cetuximab Maintenance Treatment Versus Continuation After Induction Therapy in mCRC

April 29, 2021 updated by: Jun Zhang, Ruijin Hospital

Biomarker-Panel Guided Maintenance Treatment With Cetuximab Monotherapy Versus Continuation After First Line Induction Therapy of Metastatic Colorectal Cancer (mCRC) : a Multicenter, Prospective, Randomized Controlled Trial

This study is try to evaluate the effect of cetuximab monotherapy as maintenance treatment, versus continuation after 8 courses of induction therapy with cetuximab plus standard chemotherapy regimen (FOLFIRI or mFOLFOX6）in metastatic colorectal cancer (mCRC) patients. The maintenance treatments are continued until disease progression or untolerated toxicity. The aim of this study is to demonstrate that cetuximab monotherapy is non-inferior to continuation treatment, in those mCRC patients who responded to induction therapy(SD, PR, or CR), and carry biomarker-panels (KRAS, NRAS, BRAF, and PIK3CA) favor EGFR antibody.

Detailed Description

This study is try to evaluate the effect of cetuximab monotherapy as maintenance treatment, versus continuation after 8 courses of induction therapy with cetuximab plus standard chemotherapy regimen (FOLFIRI or mFOLFOX6）in metastatic colorectal cancer (mCRC) patients. The maintenance treatments are continued until disease progression or untolerated toxicity. The aim of this study is to demonstrate that cetuximab monotherapy is non-inferior to continuation treatment, in those mCRC patients who responded to induction therapy(SD, PR, or CR), and carry biomarker-panels (KRAS, NRAS, BRAF, and PIK3CA) favor EGFR antibody. Furthermore, the mutation status of biomarker panel consist of KRAS, NRAS, HRAS, BRAF, EGFR, ERBB2, ERBB3, PIK3CA, PTEN, SMAD4, SMAD2, TGFBR2, cMET, Src, mTOR, VEGFR1, VEGFR2, EPHA2, MSI, TP53, ERCC1, ERCC5, KCNQ5, ILK, and Myc will be analyzed by NGS sequencing. The ctDNA as surrogate marker via liquid biopsy will be conducted before randomization, during maintenance treatment, and disease progression.

Phase

Phase

The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)
