Nkarta, Inc. is a clinical-stage biopharmaceutical company advancing the development of allogeneic, off-the-shelf engineered natural killer (NK) cell therapies. The Company is developing NKX019, a chimeric antigen receptor-natural killer (CAR NK) product candidate targeting the CD19 antigen for the treatment of patients with autoimmune diseases and NKX101, a CAR NK product candidate targeting cells that display NKG2D ligands. NKX019 is engineered with a humanized CD19-directed CAR for enhanced cell targeting and a proprietary, membrane-bound form of interleukin-15 (IL-15) for greater persistence and activity without exogenous cytokine support. CD19 is a biomarker for normal B cells as well as those implicated in autoimmune disease and B cell-derived malignancies. Its NKX019 autoimmune program is based on the potential to eliminate the pathologic B cells that produce autoantibodies.
