Abstract
PURPOSE OF REVIEW
The current review focuses on the preclinical development and clinical advances of natural killer (NK) cell therapeutics for hematologic malignancies and offers perspective on the unmet challenges that will direct future discovery in the field.
RECENT FINDINGS
Approaches to improve or re-direct NK cell anti-tumor functions against hematologic malignancies have included transgenic expression of chimeric antigen receptors (CARs), administration of NK cell engagers including BiKEs and TriKEs that enhance antibody-dependent cellular cytotoxicity (ADCC) by co-engaging NK cell CD16 and antigens on tumors, incorporation of a non-cleavable CD16 that results in enhanced ADCC, use of induced memory-like NK cells alone or in combination with CARs, and blockade of NK immune checkpoints to enhance NK cytotoxicity. Recently reported and ongoing clinical trials support the feasibility and safety of these approaches. NK cell-based therapeutic strategies hold great promise as cost-effective, off-the-shelf cell therapies for patients with relapsed and refractory hematologic diseases.
