SOUTH SAN FRANCISCO, Calif., May 11, 2023 (GLOBE NEWSWIRE) — Nkarta, Inc. (Nasdaq: NKTX), a biopharmaceutical company developing engineered natural killer (NK) cell therapies, today announced that it will present preliminary data from its Phase 1 dose escalation clinical trial of NKX019 at two upcoming scientific conferences in June 2023: the European Hematology Association (EHA) 2023 Hybrid Congress and the 17th International Conference on Malignant Lymphoma (17-ICML). NKX019 is an allogeneic, off-the-shelf cell therapy candidate comprising NK cells derived from healthy donors and engineered to target the B-cell antigen CD19.

The purpose of the presentations is to ensure that clinical investigators and the broader clinical community have the opportunity to assess the NKX019 clinical data from the November 2022 data cut-off in a peer-reviewed format. These data were previously disclosed at a company event in December 2022. Nkarta continues to plan to present an update to these data later in 2023.

About NKX019
NKX019 is an allogeneic, cryopreserved, off-the-shelf cancer immunotherapy candidate that uses natural killer (NK) cells derived from the peripheral blood of healthy adult donors. It is engineered with a humanized CD19-directed CAR for enhanced tumor 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 and malignant B cells, and it is a validated target for B cell cancer therapies. To learn more about the NKX019 clinical trial in adults with advanced B cell malignancies, please visit ClinicalTrials.gov.
