The protocol amendments are designed to alleviate the need for overnight stays and reduce the overall burden on patients, enabling outpatient administration of NKX019 \u2013 an investigational CAR-NK cell therapy \u2013 by community research centers and community rheumatologists.<\/p>\n<p>\u201cWe are pleased to reach agreement with the FDA on several protocol enhancements that will meaningfully improve the patient and trial site experience while supporting continued advancement of our NKX019 clinical program,\u201d said Paul J. Hastings, Chief Executive Officer of Nkarta. \u201cReaching agreement with the FDA on outpatient dosing \u2013 reducing the need for patient monitoring from 24 hours to 2 hours \u2013 will reduce patient burden and expand access.\u00a0It will also allow us to partner with community rheumatology centers, better positioning us to execute efficiently across our clinical program while expanding access to next-generation innovation to people from all walks of life, putting patients first.\u201d<\/p>\n<p>\u201cOur agreement with the FDA expands who we can treat \u2013 and how \u2013 in clinical trials. When the amended protocol completes IRB review and is finalized, we can begin enrolling patients with rheumatoid arthritis in Ntrust-2. We\u2019re also gaining the flexibility to re-dose participants in both studies, if needed, as an option to help optimize treatment responses in individual patients.\u201d<\/p>\n<p>\n        <strong>NKX019 Clinical Program Progress and Upcoming Milestones <\/strong><br \/>\n        <br \/>Following submission of the final amendments to FDA and IRB approvals:<\/p>\n<ul type=\"disc\">\n<li>Outpatient administration will be enabled for both Ntrust-1 and Ntrust-2.<\/li>\n<li>Option to re-dose will be allowed, if needed, in Ntrust-1 and Ntrust-2.<\/li>\n<li>Rheumatoid arthritis cohort will be added as an indication in Ntrust-2, expanding the study scope to address an additional autoimmune disease with significant unmet need.<\/li>\n<li>No geographic monitoring requirements remain, further reducing patient burden.\n<\/li>\n<\/ul>\n<p>\n        <strong>About the Ntrust\u2120 Clinical Trials in Autoimmune Disease<\/strong><br \/>\n        <br \/>Ntrust-1 (<a href=\"https:\/\/www.globenewswire.com\/Tracker?data=-uyrwaYONTrRditoM42Fj_AFz0xyu-gNJqODMnwTQmiei69lczWPgF8QoYOKmIR_ZsuEUajZ2I58sGP8S7rqL4wZw8h2THH0SbSIg4gCs2LS9mmF33zNYh4wm7Wcj-W7\" rel=\"nofollow\" target=\"_blank\"><u>NCT06557265<\/u><\/a>) and Ntrust-2 (<a href=\"https:\/\/www.globenewswire.com\/Tracker?data=-uyrwaYONTrRditoM42Fj4kIK6KwpKaMfJpOrak1o2XaDG_prw2WEllYeUf9eZ5dlPUDOTq6jed1lYV5oWlGgGU_jTUpD-1vIs__PogtKPpjNgAFi0CQxCOLI5j3Mj14\" rel=\"nofollow\" target=\"_blank\"><u>NCT06733935<\/u><\/a>) are multi-center, open label, dose escalation clinical trials that build on academic studies of durable, drug-free remissions in patients with autoimmune disease after CD19-targeted cell therapy. Both trials will assess the safety of NKX019 in people living with autoimmune diseases as well as its ability to enable durable remissions via a \u201creset\u201d of the immune system through the elimination of pathogenic B cells.<\/p>\n<p>The Ntrust trials are enrolling people living with lupus nephritis, primary membranous nephropathy, systemic sclerosis, idiopathic inflammatory myopathy, and ANCA-associated vasculitis, with rheumatoid arthritis expected to be added following final submission of the protocol amendment.<\/p>\n<p>In both studies, patients receive a three-dose cycle of NKX019 on Days 0, 3, and 7 following lymphodepletion with fludarabine and cyclophosphamide or cyclophosphamide alone, if they have significant cytopenia at baseline. Leveraging the engineering of NKX019, no patients in either trial will receive supplemental cytokines or antibody-based therapeutics. This approach is designed to evaluate the single-agent activity of NKX019 and facilitate a more rapid path to regulatory approval. Patients in Ntrust-1 and Ntrust-2 may receive additional cycles, if needed, to restore response or enable a deeper response.<\/p>\n<p>\n        <strong>About NKX019<\/strong><br \/>\n        <br \/>NKX019 is an allogeneic, cryopreserved, off-the-shelf 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 chimeric antigen receptor (CAR) for enhanced 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 B cells as well as those implicated in autoimmune disease. Nkarta is evaluating NKX019 in multiple autoimmune conditions.<\/p>\n<p>\n        <strong>About Nkarta<\/strong><br \/>\n        <br \/>Nkarta is a clinical-stage biotechnology company advancing the development of allogeneic, off-the-shelf natural killer (NK) cell therapies for autoimmune diseases.
