Overview
Brief Summary
This study will test the safety and effects of SBT777101 when given as a single dose to subjects with rheumatoid arthritis. It is the first study of this treatment being done in humans. Increasing dose levels will be given after the safety at lower dose levels is shown.
Detailed Description
The study evaluates the safety and effects of a novel regulatory CARTreg cell-based autoimmune and inflammatory disease therapy for the treatment of rheumatoid arthritis. The therapy is an autologous (using the patient's own cells) Treg cell therapy that targets proteins in the inflamed, disease-associated tissue, with the aim to dampen inflammation and restore balance to the immune system.
