  6. • At least 9 unstained slides containing tumor sections
  7. Documentation by PET/CT scan, CT scan, or MRI that the patient has untreated measurable metastatic disease.
  8. No immediate need for surgical intervention for the primary tumor or palliative diversion/bypass.
  9. Patients with CNS metastases are excluded, with the following exceptions:
    • • Patients with asymptomatic untreated CNS metastases may be enrolled, provided all eligibility criteria are met, as well as the following:
    •  Evaluable or measurable disease outside the CNSNo metastases to brain stem, midbrain, pons, medulla, cerebellum, or within 10 mm of the optic apparatus (optic nerves and chiasm)  No history of intracranial hemorrhage or spinal cord hemorrhage

       No ongoing requirement for dexamethasone for CNS disease; patients on a stable dose of anticonvulsants are permitted.

       No neurosurgical resection or brain biopsy within 28 days prior to randomization.

  10. Patients with asymptomatic treated CNS metastases may be enrolled, provided all eligibility criteria are met, as well as the following:Radiographic demonstration of improvement upon the completion of CNS-directed therapy and no evidence of interim progression between the completion of CNS-directed therapy and the screening radiographic study

     No stereotactic radiation or whole-brain radiation within 28 days prior to randomization

     Screening CNS radiographic study within  28 days from completion of radiotherapy and within  14 days from discontinuation of corticosteroids.

  11. Other malignancies are excluded unless the patient has completed therapy for the malignancy ≥ 12 months prior to randomization and is considered disease-free. Patients with the following cancers are eligible if diagnosed and treated within the past 12 months: in situ carcinomas or basal cell and squamous cell carcinoma of the skin.
  12.  No prior treatment with oxaliplatin chemotherapy within 6 months prior to randomization.
  13. No prior treatment with anti-PD-1, or anti-PD-L1 therapeutic antibody or pathway-targeting agents. Patients who have received prior treatment with anti-CTLA-4 may be enrolled provided the following requirements are met: Minimum of 12 weeks from the first dose of anti-CTLA-4 and > 6 weeks from the last dose to randomization

     No history of severe immune-related adverse effects (CTCAE Grade 3 and 4) from anti-CTLA-4.

  14.    No patients who have had chemotherapy or radiotherapy within 4 weeks.
  15.   No treatment with systemic immunostimulatory medications.
  16.  No treatment with systemic immunosuppressive medications. 

Research & Trial Information


Protocol#: SWOG – S0820

Cancer Type: Cancer Control & Prevention/Colorectal

Patients Eligibility:

  1. Patients must have a history of Stage 0, I, II or III colon or rectal adenocarcinoma that has been treated per standard care with resection alone or in combination with radiation or chemotherapy. Adjuvant chemotherapy and RT treatment must have been completed at least 30 days prior to registration.
  2. Patients with history of segmental resections are eligible (i.e. right colectomy, extended right colectomy, transverse colectomy, left colectomy, extended left colectomy, sigmoid colectomy, low anterior resection, abdominoperineal resection). The definition of resection does not include endomucosal resection (EMR). Patients that have received total proctocolectomy are ineligible. In addition to segmental resections, the following types of procedures are allowed: Polypectomy: For Tis (Stage 0) or pT1 patients only, resection may consist entirely of polypectomy (without completion of partial colectomy) if ALL of the following criteria are met:• Single specimen, completely removed.• Clear margins

    • None of the following must be present: o Moderate or poor differentiation

    o Lymphovascular invasion

    o Perineural invasion

  3. Transanal excision is allowed for pT1 rectal cancer patients with well or moderately differentiated tumors if NCCN criteria for transanal excision are met.
  4. Patients must be registered between 120 days and 456 days (inclusive) of primary resection. Patients must show no evidence of colorectal cancer based on post-operative colonoscopy (performed at least 120 days after the colon or rectal resection date and prior to registration). Patients with adenomas detected at the one-year postoperative colonoscopy are eligible if all adenomas have been completely removed.
  5. Patients must be at least 18 years of age.
  6. Patients must have a Zubrod Performance Status of 0 – 1.
  7. Patients must not be expecting to receive radiation or additional chemotherapy.
  8. Patients must not be receiving or plan to receive concomitant oral or intravenous corticosteroids on a regular basis, nonsteroidal anti-inflammatory drugs (NSAIDs), nor anticoagulants on a regular or predictable intermittent basis. (NSAID use may not exceed 10 days per month.) Patients may receive daily aspirin for cardiovascular prophylaxis as long as ASA is ≤ 100 mg per day or ≤ two 325 mg tablets per week. Inhaled steroids (i.e. for asthma or related conditions) are allowed.

SCHEMA A021502

Protocol#: Alliance – A021502

Cancer Type: Colorectal

Patient Eligibility:

  1. Histologically proven stage III colon adenocarcinoma (any T [Tx, T1, T2, T3, or T4], N1-2M0; includes N1C). Tumors must be deemed to originate in the colon including tumors that extend into/involve the small bowel (e.g. those at the ileocecal valve). DNA Mismatch Repair (MMR) Status: 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. Patients with testing that did not show dMMR (loss of MMR protein) are not eligible to participate. Patients whose tumors show MSI-H by 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.
  2. Tumors must have been completely resected. Entire tumor must be in the colon (rectal involvement is an exclusion). No evidence of residual involved lymph node disease or metastatic disease at the time of registration based on clinician assessment of imaging.
  3. No prior medical therapy (chemotherapy, immunotherapy, biologic or targeted therapy) or radiation therapy for the current colon cancer except for one cycle of mFOLFOX6.
  4. No active known autoimmune disease, including colitis, inflammatory bowel disease (i.e. ulcerative colitis or Crohn’s disease), rheumatoid arthritis, panhypopituitarism, adrenal insufficiency.
  5. No other planned concurrent investigational agents or other tumor directed therapy (chemotherapy, radiation) while on study and no systemic daily treatment with either corticosteroids (>10 mg daily prednisone equivalents) or other immunosuppressive medications.
