Summary

This trial will test a new treatment called NKX019 in participants with lupus kidney disease. The study will focus on assessing the safety and how well the treatment is tolerated by the participants.

Who is the study for?
This trial is for adults with active lupus nephritis, a type of kidney inflammation due to autoimmune disease. Participants must meet certain health standards but specific inclusion and exclusion criteria are not listed.
What is being tested?
The study tests NKX019, a therapy involving immune cells (CAR NK) designed to target CD19, in combination with Cyclophosphamide, a chemotherapy drug. It's an early-phase trial to assess safety and how well patients tolerate the treatment.
What are the potential side effects?
Potential side effects may include reactions related to the immune system targeting healthy cells by mistake, infusion-related reactions from the CAR NK cells or side effects from Cyclophosphamide like nausea and low blood cell counts.
