This is a Phase 1/2, open-label, multi-center, multi-cohort, non-randomized dose escalation and dose expansion basket study to determine the safety and tolerability of NKX019 (allogeneic CAR NK cells targeting CD19) in participants with autoimmune diseases.
Dose escalation of NKX019 will utilize a "3+3" design to determine the recommended dose(s) for enrolling additional participants across indications. The study will evaluate safety and tolerability, preliminary efficacy, pharmacokinetics, pharmacodynamics in participants with autoimmune diseases. Participants will receive a cycle consisting of lymphodepletion with fludarabine and cyclophosphamide (Flu/Cy), followed by three doses of NKX019. Participants who are cytopenic may receive a modified LD regimen of Cy alone.
