Nkarta Reports First Quarter 2023 Financial Results and Corporate Highlights

•Clinical updates on track for NKX101 in second quarter of 2023 at a company-hosted event and NKX019 in second half of 2023

•Cash and cash equivalents of $332.1 million on March 31, 2023

•Cash runway anticipated to fund operations into 2025

SOUTH SAN FRANCISCO, Calif., May 11, 2023 -- Nkarta, Inc. (Nasdaq: NKTX),

a clinical-stage biopharmaceutical company developing engineered natural killer (NK) cell therapies, today reported financial results for the first quarter ended March 31, 2023.

“Nkarta remains focused on the potential of donor-derived CAR NK cell products to broaden access to the transformative power of cell therapy for patients,” said Paul J. Hastings, CEO and President of Nkarta. “We look forward to announcing clinical updates for our two lead programs, NKX101 and NKX019, in 2023.”

Hastings continued, “Our update on NKX101 is expected to include responses from multiple new patients with r/r AML at the 1.5 billion cell dose level. This will include patients from an expansion cohort where cytarabine is substituted for cyclophosphamide and combined with fludarabine as a modified lymphodepletion regimen. Based on our early, encouraging safety data, we see the possibility to combine with other standard of care agents as a potential advantage that NK cell therapy may have over other available treatments. For NKX019, we continue to plan for a full update on non-Hodgkin lymphoma in the second half of the year.”

Clinical Program Updates

NKX101

•NKX101 is an allogeneic, off-the-shelf cell therapy candidate comprising NK cells derived from healthy donors and engineered to target NKG2D ligands on cancer cells.

•Nkarta plans to present additional clinical data in the second quarter of 2023 from its ongoing Phase 1 clinical trial of NKX101 in patients with relapsed or refractory acute myeloid leukemia (r/r AML).

•The update for NKX101 is expected to include longer-term follow up from patients who were in response as of the previous April 2022 data cut-off; clinical data from at least 10 new r/r AML patients treated at 1.5 billion cells/dose x 3 dose regimen; clinical data from patients who received one or more additional 3-dose cycles of NKX101; and clinical data from a new cohort of patients who received lymphodepletion with cytarabine and fludarabine.

NKX019

•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.

•Nkarta plans to present additional clinical data in the second half of 2023 from its ongoing Phase 1 clinical trial of NKX019 in patients with relapsed or refractory non-Hodgkin lymphoma (r/r NHL).

•The update for NKX019 is expected to include longer-term follow up of patient outcomes reported in the December 2022 announcement of dose expansion data, including patients eligible for retreatment with NKX019. The update is also expected to include clinical data from the recently opened dose expansion study, which is enrolling patients into three cohorts: NKX019 in patients who have not previously received autologous CD19 CAR T therapy, NKX019 in patients who previously received autologous CD19 CAR T therapy, and NKX019 as combination therapy with rituximab to evaluate for enhanced anti-tumor activity via ADCC, a tumor killing mechanism driven by antibodies.

•Prior to the clinical update in the second half of 2023, Nkarta plans to present clinical data at two scientific meetings in June 2023: the annual meeting of the European Hematology Association (EHA) and the International Conference on Malignant Lymphoma (17-ICML). These presentations will be based on the prior November 2022 data cut-off.

AACR 2023

•In April 2023, Nkarta presented preclinical data in two posters at the 2023 American Association of Cancer Research (AACR) annual meeting that showed CD16-mediated ADCC activity by combining NKX101 with a monoclonal antibody and enhancements of cytotoxic activity through genome engineering of NK cells.

Other Corporate Highlights

•In March 2023, Nkarta announced that Nadir Mahmood, PhD, resigned his position as chief financial and business officer to become the chief executive officer of a private biotechnology company. Dr. Mahmood will remain with Nkarta until June 30, 2023, to ensure a smooth transition. Nkarta is currently conducting a search for its next chief financial officer.

•R&D Expenses: Research and development (R&D) expenses were $26.1 million for the first quarter of 2023. Non-cash stock-based compensation expense included in R&D expense was $2.1 million for the first quarter of 2023.

•G&A Expenses: General and administrative (G&A) expenses were $8.2 million for the first quarter of 2023. Non-cash stock-based compensation expense included in G&A expense was $2.7 million for the first quarter of 2023.

•Net Loss: Net loss was $30.8 million, or $0.63 per basic and diluted share, for the first quarter of 2023. This net loss includes non-cash charges of $3.8 million that consisted primarily of share-based compensation of $4.7 million.

Financial Guidance

•Nkarta expects its current cash and cash equivalents will be sufficient to fund its current operating plan into 2025.

About NKX101NKX101 is an allogeneic, cryopreserved, off-the-shelf cancer immunotherapy candidate that uses natural killer (NK) cells derived from the peripheral blood of healthy donors. It is engineered with 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. NKX101 is also engineered with membrane-bound form of interleukin-15 (IL15) for greater persistence and activity without exogenous cytokine support. To learn more about the NKX101 clinical trial in adults with AML or MDS, please visit ClinicalTrials.gov.

About NKX019NKX019 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.
