Trial Summary

What is the purpose of this trial?

This trial is testing if vitamin D3 along with regular cancer drugs and another drug that helps the immune system can better treat colorectal cancer that has spread. Vitamin D3 may help the body use essential minerals, making the cancer drugs more effective. Vitamin D3 has been shown to slow down cancer cell growth and help them mature, and it has been effective in reducing intestinal tumors in animal studies.
