Phase 1 — Testing in a small group (usually 20–80 people) to find a safe dose and watch for side effects.
This is an early-stage trial testing a new medication called to see if it is safe and how the body processes it. The study has two parts: first, healthy volunteers will receive a single dose to establish basic safety, and then people with rheumatoid arthritis will receive multiple doses over time. Researchers want to understand whether this medication could eventually help treat rheumatoid arthritis.
Rheumatoid arthritis is a chronic condition that causes pain and joint damage, and doctors are always looking for new treatment options. This medication needs to be tested in humans for the first time to make sure it is safe and to learn how the body processes it before it can be considered for wider use.
If you qualify for the healthy volunteer part, you will come in for screening and then receive a single dose of the medication or placebo, followed by safety monitoring and blood tests. If you qualify for the arthritis part, you will receive three doses of the medication or placebo given every 4 weeks, with regular clinic visits to check how you are responding and to monitor for any side effects. The entire study will involve multiple visits over several months for blood work, physical exams, and safety assessments.
