IL15 Trispecific Killer Engagers (TriKE) Make natural killer cells specific to CD33+ targets while also inducing persistence, in vivo expansion, and enhanced function. The signaling domains of CAR-NK cells are very similar to those in CAR-T cells, typically composed of the fusion of CD3 with one or two TCR co-stimulatory molecule (s), such as CD28, 4-1BB, 2B4, DNAM1, and NKG2D.

Phase I clinical trial of autologous NK cell therapy using novel expansion method in patients with advanced digestive cancer. Using allogeneic NKs for adoptive transfer without expansion after a short overnight incubation with cytokines was shown to be sufficient to activate NK cells and enhance their cell cytotoxicity against tumor targets [86].
