This phase III trial studies how well vitamin D3 given with standard chemotherapy and bevacizumab works in treating patients with colorectal cancer that has spread to other parts of the body. Vitamin D3 helps the body use calcium and phosphorus to make strong bones and teeth. Drugs used in chemotherapy, such as leucovorin calcium, fluorouracil, oxaliplatin, and irinotecan hydrochloride, work in different ways to stop the growth of tumor cells by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as bevacizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving vitamin D3 with chemotherapy and bevacizumab may work better in shrinking or stabilizing colorectal cancer. It is not yet known whether giving high-dose vitamin D3 in addition to chemotherapy and bevacizumab would extend patients' time without disease compared to the usual approach (chemotherapy and bevacizumab).

  • Advanced/metastatic colorectal adenocarcinoma for which metastasectomy is not planned.
  • No mismatch repair deficiency (dMMR) or high-frequency microsatellite instability (MSI-H) disease.
  • No prior systemic treatment for metastatic disease.
  • 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.
  • 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 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.
