SOUTH SAN FRANCISCO, Calif., March 25, 2021 (GLOBE NEWSWIRE) -- Nkarta, Inc. (Nasdaq: NKTX), a clinical-stage biopharmaceutical company developing engineered natural killer (NK) cell therapies to treat cancer, today reported financial results for the fourth quarter and year ended December 31, 2020.
“We continue our work to supercharge the distinctive tumor-killing power of healthy donor-derived natural killer cells and advance our co-lead development programs in allogeneic, off-the-shelf, engineered cell therapy,” said Paul J. Hastings, President and Chief Executive Officer of Nkarta. “Our goal remains to report early clinical data from the dose finding portion of our ongoing clinical trial of NKX101 by the end of this year. In addition, we are on track to file the IND application for NKX019 this month and begin patient dosing in a multi-center clinical trial for patients with B cell malignancies in the second half of 2021. Nkarta remains committed to the transformative potential of CAR NK cell therapy for cancer patients and we strive to keep patients at the center of all that we do.”
Anticipated Clinical Milestones
- In the first quarter of 2021, Nkarta plans to file an Investigational New Drug (IND) application for NKX019, a CAR (chimeric antigen receptor) NK cell therapy candidate engineered to target tumors expressing CD19 antigen for the treatment of B-cell malignancies. Following the regulatory clearance of the IND, Nkarta expects patient dosing in a Phase 1 clinical trial of NKX019 to initiate in the second half of 2021.
- Nkarta expects to manufacture NKX019 clinical supply for the Phase 1 clinical trial at its in-house cGMP clinical manufacturing facility located in South San Francisco, California.
- Nkarta aims to present initial clinical data from its ongoing clinical trial of NKX101 in patients with r/r AML and MDS by year end. In the Phase 1 study, patients receive multiple doses of NKX101 during a 28-day treatment cycle and are eligible to receive a second cycle of treatment upon evidence of tolerability and disease response.
- 2022 milestones are expected to include an IND amendment for NKX101 for the treatment of solid tumors and an IND application for Nkarta’s third engineered CAR NK cell product candidate that is designed to target solid tumors and hematologic malignancies.

About NKX101
NKX101 is an investigational, off-the-shelf cancer immunotherapy that uses natural killer (NK) cells derived from the peripheral blood of healthy donors and engineered with membrane-bound IL15 and a chimeric antigen receptor (CAR) targeting NKG2D ligands on tumor cells. NKG2D, a key activating receptor found on naturally occurring NK cells, induces a cell-killing immune response through the detection of stress ligands that are widely expressed on cancer cells. By engineering NKX101 with the proprietary NKG2D-based CAR, the ability of NK cells to recognize and kill tumor cells in pre-clinical models is increased significantly compared to non-engineered NK cells. The addition of membrane-bound IL15, a proprietary version of a cytokine for activating NK cell growth, has been shown in pre-clinical models to enhance the proliferation, persistence and sustained activity of NK cells. A multi-center Phase 1 clinical trial of NKX101 in patients with relapsed/refractory acute myeloid leukemia (AML) or higher risk myelodysplastic syndromes (MDS) is currently enrolling. Additional information about the clinical trial is available on ClinicalTrials.gov, identifier NCT04623944.
About NKX019
NKX019 is an investigational, off-the-shelf cancer immunotherapy that uses natural killer (NK) cells derived from the peripheral blood of healthy donors and engineered with a chimeric antigen receptor (CAR) targeting the CD19 antigen and membrane-bound IL15. CD19 antigen is a B-cell marker and validated target for B-cell cancer therapies. NKX019 uses the CAR to target and bind to CD19, leading to an immune response that eliminates CD19-expressing cells in preclinical studies. The addition of membrane-bound IL15, a proprietary version of a cytokine for activating NK cell growth, has been shown in preclinical models to enhance the proliferation, persistence and activity of NK cells. Nkarta plans to file an IND application with the FDA in the first quarter of 2021. Initiation of a Phase 1 clinical trial of NKX019 in patients with advanced relapsed/refractory B cell malignancies is planned for the second half of 2021.
About Nkarta’s Platform and Natural Starting Materials
Nkarta’s engineering platform utilizes healthy adult donors as the source for NK cells. By enlisting this natural source of NK cells, Nkarta starts with bona fide NK cells already endowed with inherent tumor-recognizing and cytotoxic potencies, as compared to other more complex cell sources where these basic therapeutic features must be painstakingly designed and synthetically added to the cells. Healthy donor-derived NK cells are also available in abundance, providing a large quantity of cells with which to begin the efficient two-week manufacturing process. Finally, healthy donor-derived adult cells consist of a diverse repertoire of NK cells. By utilizing a cell source that contains the broad and naturally occurring gamut of NK cells, Nkarta has the potential to capitalize on the inherent diversity of the innate immune system and select for different NK cell sub-populations with desired characteristics.
About Nkarta’s NK Cell Technologies
Nkarta has pioneered a novel discovery and development platform for the engineering and efficient production of allogeneic, off-the-shelf natural killer (NK) cell therapy candidates. The approach harnesses the innate ability of NK cells to recognize and kill tumor cells. To enhance the inherent biological activity of NK cells, Nkarta genetically engineers the cells with a targeting receptor designed to recognize and bind to specific proteins on the surface of cancerous cells. This receptor is fused to co-stimulatory and signaling domains to amplify cell signaling and NK cell cytotoxicity. Upon binding the target, NK cells become activated and release cytokines that enhance the immune response and cytotoxic granules that lead to killing of the target cell. All of Nkarta’s NK current cell therapy candidates are also engineered with a membrane-bound IL15, a proprietary version of a cytokine known for activating NK cell growth, to enhance the persistence and activity of the NK cells.
Nkarta’s manufacturing process generates an abundant supply of NK cells that, at commercial scale, is expected to be significantly lower in cost than other current allogeneic and autologous cell therapies. Key to this efficiency is the rapid expansion of donor-derived NK cells using a proprietary NKSTIM cell line, leading to the production of hundreds of individual doses from a single manufacturing run. The platform also features the ability to freeze and store CAR NK cells for an extended period of time and is designed to enable immediate, off-the-shelf administration to patients at the point of care.
About Nkarta
Nkarta is a clinical-stage biotechnology company advancing the development of allogeneic, off the shelf natural killer (NK) cell therapies for cancer. By combining its cell expansion and cryopreservation platform with proprietary cell engineering technologies, Nkarta is building a pipeline of cell therapy candidates generated by efficient manufacturing processes, which are engineered to enhance tumor targeting and improve persistence for sustained activity in the body.
