Donor NK Cells + Temozolomide

PRIMARY OBJECTIVES: I. To confirm the safety and tolerability of UD TGFbetai NK cells in combination with temozolomide as a lymphodepleting agent in patients with melanoma metastatic to the brain and to determine the recommended phase 2 dose (RP2D). (Phase 1) II. To determine the intracranial response rate. (Phase 2) SECONDARY OBJECTIVES: I. To define the toxicities of UD TGFbetai NK cells when delivered with temozolomide as a lymphodepleting agent. (Phase 1) II.

To define the pharmacokinetics (pK) associated with UD TGFbetai NK cells when used in combination with temozolomide as a lymphodepleting agent in patients with metastatic melanoma. (Phase 1) III. To determine the extracranial response rate. (Phase 2) IV. To determine progression free survival (PFS) (intracranial, extracranial, overall). (Phase 2) V. To assess overall survival (OS). (Phase 2) VI.

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.
