UD TGFbetai NK Cells(Ohio State University Comprehensive Cancer Center)

This phase I/II trial tests the safety, side effects, and best dose of universal donor UD TGFbetai natural killer (NK) cells, and whether UD TGFbetai NK cells with temozolomide works to shrink tumors in patients with stage IV melanoma that has spread to the brain (metastatic to the brain). NK cells are immune cells that contribute to anti-tumor immunity by recognizing and destroying transformed or stressed cells. Temozolomide is in a class of medications called alkylating agents. It works by slowing or stopping the growth of cancer cells in the body. Giving UD TGFbetai NK cell and temozolomide may work better in treating patients with stage IV melanoma.
