Memory-like natural killer cells(Washington University School of Medicine)

This is a Phase 1 open-label, study designed to characterize the safety, tolerability, and preliminary anti-tumor activity of memory-like natural killer cells (ML NK) in combination with nivolumab and relatlimab in subjects with advanced and/or metastatic melanoma. There will be two arms to test the variables of ML NK cell source. ML NK cells from an autologous source will be used for Arm 1, and ML NK cells from an allogeneic source will be used for Arm 2. The investigators hypothesize that ML NK cells from either an autologous source or allogeneic source are safe and tolerable in subjects with advanced and/or metastatic melanoma.
