Research Statement

Dr. Leonid Metelitsa’s research focuses on understanding the role of Vα24-invariant natural killer T (NKT) cells in tumor immunity and translating this knowledge into NKT cell-based cancer immunotherapies. His group was the first to demonstrate that NKT cells localize to primary tumors in human patients and that presence of these cells at the tumor site is associated with favorable outcomes in the clinic (Metelitsa et al., JEM, 2004). Further studies revealed the underlying mechanistic basis of NKT cell tumor localization and function in the tumor microenvironment (Song et al., JCI, 2007; Song et al., JCI, 2009, Liu et al., JCI, 2012).

Based on the knowledge gained from studying NKT cell immunobiology, he has developed original technologies and processes for NKT cell isolation, genetic modification with chimeric antigen receptors (CARs), and ex vivo expansion to clinical scale (Heczey et al., Blood, 2014; Tian et al., JCI, 2016; X. Xu et al., Clin Can Res, 2019). These efforts have resulted in initiation of first-in-human CAR NKT cell clinical trials using autologous (NCT03294954; Heczey et al. Nat Med, 2020) or allogeneic (NCT03774654) NKT cells that are ongoing.
