Overview
The goal of this clinical trial is to learn if CIT-013 works to treat rheumatoid arthritis in adults. It will also learn about the safety of CIT-013. The main questions it aims to answer are:
Does CIT-013 lower the disease activity of RA patients? What medical problems do participants have when receiving CIT-013? Researchers will compare CIT-013 to a placebo (a look-alike substance that contains no drug) to see if CIT-013 works to treat the symptoms of RA.
Participants will:
Take receive CIT-013 or placebo every other week for 6 weeks and 50 mg CIT-013 for 6 weeks Visit the clinic once every 2 weeks for checkups and tests Keep monitor their symptoms during this period
