Study Summary

This phase II trial studies the side effects and how well niraparib and panitumumab work in treating patients with colorectal cancer that has spread to other places in the body. Niraparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as panitumumab, may help the body's immune system attack the cancer and may interfere with the ability of tumor cells to grow and spread. Giving niraparib and panitumumab may work better in treating patients with colorectal cancer.

Primary Outcome

The efficacy, as measured by clinical benefit rate (CBR), will be assessed for the total number of patients enrolled. CBR = (Complete Response + Partial Response + Stable Disease \[CR +PR + SD\] rate. Response will be assessed by Response Evaluation Criteria in Solid Tumors (RECIST) v.1.1 criteria using an independent review.
