Phase 1/2 Study of NKX019 for Lupus Nephritis and Primary Membranous Nephropathy

This study, called Ntrust-1, is testing an investigational drug called NKX019 for people with autoimmune diseases like Lupus Nephritis and Primary Membranous Nephropathy. NKX019 is a type of cell therapy (allogeneic CD19-Directed CAR NK). You would receive NKX019 after a short treatment with fludarabine and cyclophosphamide, which helps prepare your body for the cell therapy. Researchers want to see how safe NKX019 is and if it causes any side effects. They are also looking at how well it works. This study is open to adults aged 18 to 75. The study plans to enroll about 120 participants, but its current status is unclear.

Study design
This is a Phase 1/2, open-label study, meaning both you and your study doctor will know which treatment you are receiving. It involves multiple centers and will enroll about 120 participants.
What's involved
You would receive a cycle of treatment including fludarabine and cyclophosphamide, followed by three doses of NKX019. You would need to follow a schedule of study visits and other protocol requirements.
Compensation
Not stated in the trial record.
Follow-up
Your safety will be monitored for at least 30 days after your last study treatment, and for clinically significant lab changes until your last follow-up visit.
