Study of Surovatamig for Rheumatoid Arthritis or Lupus

This study is testing a new medication called Surovatamig for adults with rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE). Surovatamig is given as a shot under the skin. The main goal of this study is to see how safe Surovatamig is and how well your body tolerates it. Researchers will also look at how the drug moves through your body (pharmacokinetics or PK) and what effects it has (pharmacodynamics or PD). You can join if you are between 18 and 65 years old and have been diagnosed with RA or SLE. The study will measure any side effects, serious problems, or reasons people stop taking the drug over a period of up to 52 weeks.

Study design
This is an open-label, Phase I study with 48 planned participants. It will involve different groups receiving increasing doses of Surovatamig.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for safety evaluations from Day 1 up to 52 weeks after starting the study.
