Exhibit 99.1






Nkarta Reports Second Quarter 2021 Financial Results and Business Progress



Initial data from NKX101 clinical trial expected by end of 2021



NKX019 patient dosing expected to start in 2H 2021



Collaboration with CRISPR Therapeutics to develop gene-edited cell therapies



New lease for commercial manufacturing center / headquarters to support rapid innovation and scaled production of NK cell therapies



SOUTH SAN FRANCISCO, Calif., Aug. 12, 2021 -- Nkarta, Inc. (Nasdaq: NKTX), a biopharmaceutical company developing engineered natural killer (NK) cell therapies to treat cancer, today reported financial results for the second quarter ended June 30, 2021.


“Nkarta continues to set the pace for NK cell therapy as we build on the strengths of our next generation platform and advance our two co-lead clinical programs,” said Paul J. Hastings, President and Chief Executive Officer of Nkarta. “During the period, we initiated collaboration activities with CRISPR Therapeutics, added new platform capabilities for rapid innovation, and expanded our manufacturing footprint – all designed to stay ahead of the technology curve and  transform the scientific insights of cell therapy into meaningful medicines for cancer patients. Nkarta remains on track to report initial clinical data from our Phase 1 study of NKX101 by the end of this year.”







Nkarta aims to present initial clinical data from its ongoing clinical trial of NKX101 by year end 2021. In the Phase 1 study, patients receive multiple doses of NKX101 during a 28-day treatment cycle and are eligible to receive subsequent cycles of treatment upon evidence of tolerability and disease response.



Nkarta expects patient dosing in a Phase 1 clinical trial of NKX019 to initiate in the second half of 2021 and has begun manufacturing of clinical supply of NKX019 at its in-house cGMP clinical manufacturing facility in South San Francisco, California.



Nkarta entered a lease agreement to establish a combined manufacturing facility  and company headquarters. The manufacturing facility will produce materials for potential pivotal trials and commercial launch of multiple engineered NK cell therapy products. The expanded manufacturing footprint, centered in South San Francisco, California, builds upon Nkarta’s existing 2,700 square foot cGMP clinical manufacturing facility.


Pipeline and Platform

In May 2021, Nkarta and CRISPR Therapeutics announced a research and development collaboration to co-develop and co-commercialize two chimeric antigen receptor (CAR) NK cell product candidates, one targeting CD70, and one combining NK and T cells (NK+T), each enhanced with genome engineering. The collaboration also gives Nkarta a license to CRISPR/Cas9 gene editing technology for use in its own engineered NK cell therapy products.


Nkarta continues to integrate important scientific insights, processes and breakthroughs into its next generation  platform. Platform capabilities include:



Multiplexed CRISPR/Cas9 genome engineering



“Armored” cells with membrane-bound IL-15 for persistence



Enhanced expansion, persistence and activity against tumor microenvironment inhibition via CISH deletion



Cytokine activation using IL-12, -15 and -18 to enhance anti-tumor activity persistence and memory-like properties



No requirement for cytokine support



Multi-dose and multi-cycle clinical trial designs





Cash and Cash Equivalents: As of June 30, 2021, Nkarta had cash, cash equivalents, restricted cash and short-term investments of $280.3 million.


R&D Expenses: Research and development expenses were $16.0 million for the second quarter of 2021. Non-cash stock-based compensation expense included in R&D expense was $1.7 million for the second quarter of 2021.


G&A Expenses: General and administrative expenses were $5.7 million for the second quarter of 2021. Non-cash stock-based compensation expense included in G&A expense was $1.9 million for the second quarter of 2021.


Net Loss. Net loss was $21.5 million, or $0.66 per basic and diluted share, for the second quarter of 2021.








Nkarta expects its current cash and cash equivalents will be sufficient to fund its current operating plan into at least the second half of 2023.


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 CD19-directed chimeric antigen receptor (CAR) and a proprietary, membrane-bound form of interleukin 15 (IL-15). CD19 is a biomarker for normal and malignant B cells, and it is a validated target for B cell cancer therapies. Via its CAR, NKX019 targets and binds to CD19 and eliminates CD19-expressing cells via a robust immune response in preclinical studies. Preclinical models also demonstrate enhanced proliferation, persistence and activity of NK cells with the membrane-bound IL-15, an important cytokine for NK cell survival. Initiation of a Phase 1 clinical trial of NKX019 in patients with relapsed/refractory B cell malignancies in multiple centers in the United States and Australia 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 endowed with inherent tumor-recognizing ability and potent cytotoxic function. 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, providing Nkarta with the potential to capitalize on the inherent diversity of the innate immune system in selecting donors or NK cell populations with optimal 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 patients. 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.
