ClinConnect Summary
This clinical trial is exploring a new treatment option using special immune cells called CD19 CAR NK cells for patients who have refractory antisynthetase antibody syndrome (ASyS) or rheumatoid arthritis (RA). The goal is to see if three infusions of these cells can help improve symptoms and reduce the number of certain harmful cells in the body. The study will focus on how safe this treatment is and whether it can effectively help patients who haven't responded well to other treatments.
To participate in this study, you need to be an adult between the ages of 18 and 70 who has been diagnosed with RA or ASyS for at least three months and has had a poor response to at least one previous treatment. Participants will undergo several assessments to ensure they are healthy enough for the trial. If you decide to join, you can expect to receive the infusions and be monitored closely for any side effects or improvements in your condition. It’s important to know that this trial is not yet recruiting participants, so there will be a wait before it starts.
