Nkarta (NKTX) announced the opening of enrollment for Ntrust-2 and IND clearance for an investigator-sponsored trial (IST) evaluating NKX019, their allogeneic CD19-directed CAR NK-cell therapy. Ntrust-2 will evaluate the treatment across three parallel cohorts: systemic sclerosis, myositis, and ANCA-associated vasculitis. The IST will study NKX019 in myasthenia gravis patients.
The treatment protocol involves administering NKX019 on Days 0, 3, and 7 following lymphodepletion with cyclophosphamide. The therapy aims to provide a safe, accessible treatment option for autoimmune diseases through B-cell depletion, potentially enabling long-term remissions via immune system reset.
Patient dosing has begun in both Ntrust-1 and the IST for systemic lupus erythematosus, with preliminary data from Ntrust-1 and Ntrust-2 expected in 2025.
