Read our Rheumatoid Arthritis research guide →Phase 1 — Testing in a small group (usually 20–80 people) to find a safe dose and watch for side effects.
Researchers want to understand how a special imaging technique using a dye called can help track how well rheumatoid arthritis treatment is working. The study will inject this dye into your hand and use near-infrared light to photograph the lymphatic vessels—the tiny channels that help your body fight inflammation. By taking pictures before and after you start anti-TNF therapy, researchers hope to learn if this imaging method can predict whether your treatment will work.
Right now, doctors rely on blood tests and physical exams to know if rheumatoid arthritis treatment is helping. This trial exists to see if imaging the lymphatic system could provide an earlier, more direct way to measure whether this medication is reducing inflammation in your joints.

If you have early arthritis, you'll visit the clinic three times over about one year: at the start (before you begin your new medication), at 16 weeks, and at one year. At each visit, researchers will inject the special dye into your hand and take imaging pictures right away and again one week later. If you have established arthritis, you'll have just one or two brief visits where you receive the dye injection and imaging. The whole process is non-invasive and outpatient—you won't need surgery or hospital stays.
