Current challenges Activation of NK cell cytotoxicity. Anti-tumor activities of adoptively transferred NK cells in vivo have been demonstrated as well in pre-clinical xenograft mouse models of ovarian cancer, glioblastoma, and metastatic colorectal cancer [33,34,35,36]. This TriKE design (GTB-3550) is currently in clinical trial for treating high-risk hematological malignancies (NCT03214666). IL-21 has cumulative activation effect in combination with IL-2 [119] or IL-15. Stem Cell Res Ther.

The exciting results from Liu et al. Barrow AD, Martin CJ, Colonna M. The natural cytotoxicity receptors in health and disease. 2017;18(1):5667. The concept of adoptive NK cell cancer immunotherapy was proven a decade ago from pioneering clinical studies against hematological malignancies. Two CD19-targeting CAR-T products were approved by the FDA for treatment of B cell lymphomas and acute lymphoblastic leukemia (ALL). Distinct from T cells, there is no master transcriptional factor that controls NK cell development. It is now understood that the adaptive-like NK cells express the activating receptor NKG2C and that the adaptive nature of NKG2C+ NK cells attributes to the non-classical MHC I molecule HLA-E presenting CMV-specific viral peptide to NKG2C [22]. WebPhysiological barriers and immunosuppressive microenvironments of solid tumors present considerable hurdles to Chimeric antigen receptor T (CAR-T) cell therapy. Front Immunol. 2018;67(4):57587. The trial is Cytotherapy. The off-shelf NK cell therapeutic product oNKord, the allogeneic partial HLA-matched NK cells derived from UCB-CD34+ progenitors, has received an orphan drug designation from EMA and FDA for treating AML patients who were not eligible for allogeneic stem cell transplantation. For instance, healthy cells express no or minimal level of ligands for NK cell activating receptors, but express high levels of the major histocompatibility complex class I molecules (MHC I), also known as human leukocyte antigen (HLA), that ligates to the killer immunoglobulin-like (KIR) family inhibitory receptors on NK cells to protect them from NK attack [29]. PLoS ONE. For example, there is an ongoing phase 2 clinical trial to evaluate the safety and efficacy of human HLA-haploidentical hematopoieticcelltransplantation (HCT) followed by an early, post-transplant infusion of donor NKcells (NCT02100891). This successful immunotherapy has led to a more complete view of cancer that now considers not only the cancer cells to be targeted and destroyed but also the immune environment of the cancer cells. The FDA has cleared Artiva Biotherapeutics investigational new drug (IND) application for the chimeric antigen receptor NK (CAR-NK) cell therapy AB-201 for the NKG2D, an activating NK cell receptor, can bind to eight different stress-induced ligands that are naturally expressed on 80% of hematological and solid cancer Current challenges Hepatocellular carcinoma (HCC) is a high-incidence malignant tumor worldwide and lacks effective treatment options.

Lee J, et al. volume14, Articlenumber:7 (2021) As an alternative to CAR-T cell therapy, CAR-NK cell therapy not only circumvents these challenges but also presents additional major advantages: (i) the ability to use unlimited allogeneic NK source without concern of GVHD [6, 31, 32]; (ii) the potential to generate off-shelf product with NK cell line or iPSC-NK [37,38,39,40,41]; (iii) relatively shortened production time; iv) recognition and killing tumor cells through NK cell native receptors independent of the CAR engineering [42], less likely allowing disease escape through downregulation of the CAR antigens as shown with CAR-T cell therapy [37].

However, CAR-T therapy has two major challenges: (i) requirement of a substantiate length of time to generate a therapeutic dose of autologous CAR-T cells which limits its feasibility to treat patients with rapidly progressing diseases; (ii) difficulty to obtain sufficient number of autologous T cells for CAR-T cell generation from heavily pre-treated and often lymphopenic cancer patients [37]. 2013;73(6):177786.

WebThese antibodies are currently used in clinical trials in the treatment of both hematological and solid tumors. However, the exhaustion of T cells or NK cells can lead to the failure of tumor control and limit the complete response and overall efficacy of cancer immunotherapy against solid tumors. CAS 2015;2:93. Using an array of germline-encoded surface receptors, NK cells are able to recognize and rapidly act against malignant cells without prior sensitization. In mouse strains lacking NK1.1 expression (e.g., BALB/c), CD49b is used for NK cell identification. Targeted drugs are the preferred recommendations for the systemic treatment of hepatocellular carcinoma. Moreover, highly cytotoxic NK cells derived using such method are capable of producing endogenous cytokines that improve their survival, proliferation, and function [132]. This protocol created a possibility to generate a substantially higher number of NK cells from a single dose of peripheral blood [131] and is currently in phase I/II clinical trial (NCT01787474) with expanded haploid-identical NK cells for treating relapsed or refractory AML.
