Nkarta Presents NKX019 Clinical Data at the European Hematology Association 2023 Congress and 17th International Conference on Malignant Lymphoma - Seite 2

“These data highlight the encouraging safety profile and clinical activity across different histologies in the dose escalation portion of the NKX019 study,” said David R. Shook, M.D., Nkarta’s Chief Medical Officer. “We continue to explore the potential of allogeneic CAR NK cells, leveraging their biology to create a differentiated cellular therapy, and we look forward to the next update on the NKX019 program later this year.”

Nkarta’s presentation materials from EHA and ICML will be available for download on the Nkarta website (https://www.nkartatx.com/publications/). The presentations will ensure that the broader clinical and academic community has the opportunity to assess the NKX019 clinical data in a peer-reviewed format. All data were previously disclosed at a company event in December 2022. Nkarta plans to provide an update from the NKX019 program, including data from dose expansion cohorts, 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.
