Randomized Trial of Standard Chemotherapy Alone or Combined With Atezolizumab as Adjuvant Therapy for Patients With Stage III Colon Cancer and Deficient DNA Mismatch Repair

Overview

This phase III trial studies combination chemotherapy and atezolizumab to see how well it works compared with combination chemotherapy alone in treating patients with stage III colon cancer and deficient deoxyribonucleic acid (DNA) mismatch repair.

Description

The purpose of this study is to determine whether atezolizumab combined with oxaliplatin, leucovorin calcium, and fluorouracil (FOLFOX) and its continuation as monotherapy can significantly improve disease-free survival (DFS) compared to FOLFOX alone in patients with stage III colon cancers and deficient DNA mismatch repair (dMMR).

Eligibility

You may be eligible for this study if you meet the following criteria:

  • Conditions: DNA repair disorder,Lynch Syndrome,colon cancer,colon adenocarcinoma
  • Age: Between 18 Years - 100 Years
  • Gender: Male or Female

Inclusion Criteria
In order to be eligible to take part in this trial, patients must meet the following criteria:

  • Histologically proven stage III colon adenocarcinoma (any T [Tx, T1, T2, T3, or T4], N1-2M0; includes N1C)
  • Presence of deficient (d) DNA mismatch repair (dMMR); MMR status must be assessed by immunohistochemistry (IHC) for MMR protein expression (MLH1, MSH2, MSH6, PMS2) where loss of one or more proteins indicates dMMR; dMMR may be determined either locally or by site-selected reference lab; Note: loss of MLH1 and PMS2 commonly occur together; formalin-fixed paraffin-embedded (FFPE) tumor tissue is required for subsequent retrospective central confirmation of dMMR status
