ClinConnect Summary
This clinical trial is investigating a new treatment using a special type of immune cell therapy called CAR-T cells for patients with certain autoimmune diseases, including Systemic Lupus Erythematosus, Sjogren's Syndrome, and others that have not responded well to standard treatments. The goal is to see if these CAR-T cells can help improve symptoms and overall health in individuals who continue to experience disease flare-ups despite ongoing care.
To be eligible for this trial, participants must be between 18 and 65 years old and have specific types of autoimmune diseases that have not improved with traditional treatments. They will need to undergo some tests to ensure their organs are functioning well before receiving the treatment. During the trial, participants can expect close monitoring for safety and effectiveness. It's important to know that participants will need to sign an informed consent form and should be willing to follow the study guidelines carefully. Overall, this trial aims to explore a promising new option for people struggling with difficult-to-treat autoimmune diseases.
