Summary

This trial is testing a new cell product called AB-101, which contains natural killer cells that can enhance the effect of antibody therapies. The trial will enroll adults with lupus nephritis who have not

Who is the study for?
This trial is for adults with Class III or IV lupus nephritis, a serious kidney condition caused by lupus, who haven't improved with standard treatments. Participants may also have Class V lupus nephritis. They must be able to receive the study medications and follow-up assessments.
What is being tested?
The trial tests AB-101 (AlloNK), an immune cell therapy designed to boost antibody treatments, in combination with rituximab after pre-treatment with cyclophosphamide and fludarabine. It aims to see if this combo is safe and effective for those whose lupus nephritis didn't respond to other therapies.
What are the potential side effects?
Potential side effects include reactions related to the immune system's enhancement such as fever, fatigue, infusion-related reactions from rituximab, and possible low blood counts due to chemotherapy agents like cyclophosphamide and fludarabine.
