Combination Chemotherapy With or Without Atezolizumab in Treating Patients With Stage III Colon Cancer and Deficient DNA Mismatch Repair
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
This randomized 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. Drugs used in combination chemotherapy, such as oxaliplatin, leucovorin calcium, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as atezolizumab, may interfere with the ability of tumor cells to grow and spread. Giving combination chemotherapy with atezolizumab may work better than combination chemotherapy alone in treating patients with colon cancer.

PRIMARY OBJECTIVES:

I. 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).

SECONDARY OBJECTIVES:

I. To determine whether atezolizumab combined with FOLFOX and its continuation as monotherapy can significantly improve overall survival compared to FOLFOX alone in patients with stage III colon cancers and dMMR.

II. To assess the adverse events (AE) profile and safety of each treatment arm, using the Common Terminology Criteria for Adverse Events (CTCAE) and patient related outcomes (PRO)-CTCAE.

TERTIARY OBJECTIVES:

I. To determine the impact of the addition of atezolizumab to FOLFOX on patient-reported neuropathy, health-related quality of life (QOL), and functional domains of health-related QOL.

II. To determine if the "immunoscore" can predict the efficacy of atezolizumab for disease-free survival among patients with stage III colon cancer.

III. To assess whether circulating immune cell populations can predict the efficacy of atezolizumab as adjuvant therapy for stage III colon cancer.

IV. To explore the associations of genomic alterations identified in cell-free (cf)DNA with DFS in patients treated with FOLFOX with or without atezolizumab.

V. To assess whether soluble markers of systemic inflammation in blood can predict the efficacy of atezolizumab as adjuvant therapy for stage III colon cancer.

VI. To assess the relationship between baseline plasma 25(OH) D levels, change in 25(OH)D levels, and DFS and overall survival (OS) in patients with stage III colon cancer receiving FOLFOX +/- atezolizumab.

VII. To determine the ability of using fecal microbiota and their metabolic products to predict survival benefit from anti-PD-L1 antibody therapy in dMMR colon cancer patients.

VIII. To determine if hypermutation or hyper-indel status is associated with response to atezolizumab.

IX. To determine if unique messenger ribonucleic acid (mRNA) expression signatures are predictive of disease-free survival among patients receiving adjuvant chemotherapy for stage III colon cancer.

X. To determine if the efficacy of atezolizumab differs among dMMR cancers due to germline MMR mutation (MLH1, MSH2, MSH6, PMS2) versus those with MLH1 hypermethylation and CIMP in patients with stage III colon cancer.

XI. To identify overall mutational burden and number of putative tumor neoantigens in colon carcinoma specimens.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive oxaliplatin intravenously (IV) over 2 hours and leucovorin calcium IV over 2 hours on day 1, and fluorouracil IV as a bolus on day 1, then continuously over 46 hours on days 1-3. Treatment repeats every 14 days for up to 12 courses in the absence of disease progression or unacceptable toxicity. Patients also receive atezolizumab IV over 30-60 minutes starting on day 1 of course 1 or 2. Treatment repeats every 14 days for up to 25 courses in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive oxaliplatin IV over 2 hours and leucovorin calcium IV over 2 hours on day 1, and fluorouracil IV as a bolus on day 1, then continuously over 46 hours on days 1-3. Treatment repeats every 14 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for recurrence every 6 months for 2 years, then annually for 3 years. Patients are also followed up for survival every 6 months for up to 8 years.

  • 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
  • Patients with testing that did not show dMMR (loss of MMR protein) are not eligible to participate; patients whose tumors show MSI-H by polymerase chain reaction (PCR)-based assay are not eligible to participate unless they also have MMR testing by IHC and are found to have dMMR (i.e. loss of one or more MMR proteins)
  • Patients who are known to have Lynch syndrome and have been found to carry a specific germline mutation in an MMR gene (MLH1, MSH2, MSH6, PMS2) are eligible to participate
  • Tumors must have been completely resected; in patients with tumor adherent to adjacent structures, en bloc R0 resection must be documented; positive radial margins are not excluded as long as en bloc resection was performed; proximal or distal margin positivity is excluded
  • Entire tumor must be in the colon (rectal involvement is an exclusion); surgeon confirmation that entire tumor was located in the colon is required only in cases where it is important to establish if the tumor is a colon versus (vs.) rectal primary
  • Based upon the operative report and other source documentation, the location of the primary tumor will be categorized as proximal or distal to the splenic flexure (distal includes), and further categorization will be as follows: cecum/ascending, descending, sigmoid colon, or rectosigmoid colon
  • No evidence of residual involved lymph node disease or metastatic disease at the time of registration based on clinician assessment of imaging; the treating physician will determine if incidental lesions on imaging require workup to exclude metastatic disease; if based on review of images, the treating physician determines the patient to be stage III, then the patient is eligible
  • No prior medical therapy (chemotherapy, immunotherapy, biologic or targeted therapy) or radiation therapy for colon cancer except for one cycle of mFOLFOX6
