Clinical Research Trials

Key Trial Criteria

• Key Inclusion Criteria

  For a patient to be eligible for participation in this study, all of the following criteria must apply

  • Histologically confirmed advanced/metastatic colorectal adenocarcinoma for which metastasectomy is not planned.
  • No mismatch repair deficiency (dMMR) or high-frequency microsatellite instability (MSI-H) disease.
  • Measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1.
  • No prior systemic treatment for metastatic disease.
  • Patients may have received prior neoadjuvant or adjuvant chemotherapy and/or chemoradiation. The last course of adjuvant therapy must have been completed > 12 months prior to colorectal cancer recurrence.
  • Patients may have received prior standard rectal cancer chemoradiation so long as prior radiotherapy was to =< 25% of bone marrow. Previous radiation therapy must have been completed >= 4 weeks prior to registration.
  • No continuous daily use of vitamin D supplements >= 2,000 IU per day for the 12 months prior to registration. Patients may have had continuous daily use of vitamin D supplements >= 2,000 IU per day if total duration < 12 months in the 12 months prior to registration. Patients may have had continuous daily use of vitamin D supplements < 2,000 IU per day for any duration prior to registration.
  • Patients must have completed any major surgery or open biopsy >= 4 weeks prior to registration and must have completed any minor surgery or core biopsy >= 1 week prior to registration. (Note: insertion of a vascular access device is not considered major or minor surgery.) Patients must have recovered from the effects of any surgery (e.g. wound is healed, no active infection, no drains, etc.) prior to registration.
  • Not pregnant and not nursing. This study involves an agent that has known genotoxic, mutagenic, and teratogenic effects. Therefore, for women of childbearing potential only, a negative serum or urine pregnancy test done =< 14 days prior to registration is required.
  • Eastern Cooperative Oncology Group (ECOG) performance status: 0-1.
  • Absolute neutrophil count >= 1,500/mm^3.
  • Platelet count >= 100,000/mm^3.
  • Hemoglobin >= 9 g/dL.
  • Creatinine =< 1.5 x upper limit of normal (ULN) OR calculated (Calc.) creatinine clearance (CrCl) > 30 mL/min.
  • Calcium =< 1.0 x ULN. *Corrected for albumin level if albumin not within institutional limits of normal.
  • Total bilirubin =< 1.5 x ULN.* If Gilbert's disease, use direct bilirubin instead of total bilirubin; direct bilirubin =< 1.5 x ULN if patient to receive FOLFIRI; direct bilirubin =< 3.0 x ULN if patient to receive leucovorin, infusional fluorouracil, and oxaliplatin (modified [m]FOLFOX6).
  • Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) =< 2.5 x ULN.* AST/ALT < 5 x ULN if clearly attributable to liver metastases.
  • Urine protein to creatinine (UPC) ratio < 1 OR urine protein =< 1.
  • No resectable metastatic disease for which potentially curative metastasectomy is planned.
  • No "currently active" second malignancy other than non-melanoma skin cancers or cervical carcinoma in situ. Patients are not considered to have a "currently active" malignancy if they have completed therapy and have been free of disease for >= 3 years.
  • No significant history of bleeding events or bleeding diathesis =< 6 months of registration unless the source of bleeding has been resected.
  • No history of arterial thrombotic events, including, but not limited to, transient ischemic attack, cerebrovascular accident, unstable angina, angina requiring surgical or medical intervention, or myocardial infarction =< 6 months of registration.
  • No history of clinically significant peripheral artery disease =< 6 months of registration.
  • No history of uncontrolled congestive heart failure defined as New York Heart Association (NYHA) class III or greater.
  • No history of gastrointestinal (GI) perforation =< 12 months of registration except for GI perforation related to a primary colorectal tumor that has since been fully resected.
  • No history of malabsorption, uncontrolled vomiting or diarrhea, or any other disease significantly affecting GI function that could interfere with the absorption of oral agents.
  • No history of allergic reaction attributed to compounds of similar chemical or biological composition to the study agents.
  • No uncontrolled hypertension (defined as blood pressure [BP] > 160/90).
  • No serious or non-healing wound, ulcer, or bone fracture.
  • No uncontrolled intercurrent illness, including, but not limited to, psychiatric illness/social situations that, in the opinion of the treating physician, may increase the risks associated with participation or treatment on the study or may interfere with the conduct of the study or interpretation of the study results.
  • Patients positive for human immunodeficiency virus (HIV) are eligible only if they meet all of the following:
    • On effective anti-retroviral therapy
    • Undetectable HIV viral load by standard clinical assay =< 6 months of registration.
  • No known pre-existing hypercalcemia =< 6 months of registration.
  • No known active hyperparathyroid disease or other serious disturbance of calcium metabolism =< 5 years of registration.
  • No predisposing colonic or small bowel disorders in which symptoms are uncontrolled as indicated by > 3 watery or soft stools daily in patients without a colostomy or ileostomy. Patients with a colostomy or ileostomy are allowed per treating physician discretion.
  • No symptomatic genitourinary stones =< 12 months of registration.
  • Patients with treated brain metastases are eligible if follow-up imaging after central nervous system (CNS)-directed therapy shows no evidence of progression >= 28 days prior to registration.
  • Patients with new or progressive brain metastases (active brain metastases) or leptomeningeal disease are eligible if the treating physician determines that immediate CNS-specific treatment is not required and is unlikely to be required during the first cycle of protocol-specified therapy after registration.
  • No uncontrolled seizure disorders.
  • No grade >=2 peripheral neuropathy, neurosensory toxicity, or neuromotor toxicity per Common Terminology Criteria for Adverse Events (CTCAE) v5.0 regardless of causality.
  • Patients must be able to swallow oral formulations of the agent.
  • Concurrent use of supplemental calcium and/or vitamin D is not permitted. Patients must discontinue the supplement(s) at least 7 days prior to registration.
  • Concurrent use of thiazide diuretics (e.g. hydrochlorothiazide) is not permitted. Patients must discontinue the drug(s) or switch to an alternative anti-hypertensive agent at least 7 days prior to registration.
  • Chronic concomitant treatment with oral corticosteroids, lithium, phenytoin, quinidine, isoniazid, and/or rifampin are not permitted. Patients must discontinue the agent(s) at least 7 days prior to registration. Short-term use of corticosteroids as antiemetic therapy is acceptable.
  • Concurrent use of other anti-cancer therapy including chemotherapy, targeted, and/or biological agents is not permitted.
