- Rheumatoid arthritis trials study DMARDs, biologics, targeted therapies, and management approaches.
- Trials follow phases, from early safety testing to larger effectiveness studies.
- ClinicalTrials.gov is the main free registry to search for RA studies.

Rheumatoid arthritis (RA) is an autoimmune condition in which the immune system attacks the joints, causing pain, swelling, and, over time, joint damage. Treatment has advanced considerably, and clinical trials continue to test new medications and strategies. This guide explains what RA trials study, how they are structured, and how to search for and evaluate studies safely.
What rheumatoid arthritis trials study
According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), RA is often managed with disease-modifying antirheumatic drugs (DMARDs) and biologics that target the immune system. Trials reflect this: they may test new DMARDs, biologic and targeted synthetic drugs (such as JAK inhibitors), combination strategies, ways to taper medication in people doing well, or approaches to reduce flares and protect joints. Some studies are observational, following participants over time to understand disease patterns and outcomes rather than testing a new drug.
The phases of a clinical trial
Medication trials generally move through defined phases, each with a different goal.
| Phase | Main goal | Typical size |
|---|---|---|
| Phase 1 | Check safety and dosing | Small |
| Phase 2 | Look at early effectiveness and side effects | Larger |
| Phase 3 | Confirm benefit vs. placebo or standard care | Large |
| Phase 4 | Track long-term safety after approval | Varies |
How to find rheumatoid arthritis clinical trials
The primary free registry is ClinicalTrials.gov, run by the U.S. National Institutes of Health. Search “rheumatoid arthritis” with your location, age, and recruitment status. Each listing shows eligibility, procedures, sites, and a contact. University rheumatology departments and NIAMS-supported research centers frequently run RA studies, and your rheumatologist may know of trials that fit your situation. If you are comparing research options, our guides to lupus clinical trials and cystic fibrosis studies follow the same search steps for other conditions.
Informed consent and your rights
Every legitimate trial begins with informed consent: the study team explains the purpose, procedures, risks, benefits, and your rights, and answers your questions before you decide. Participation is voluntary, and you can withdraw at any time without losing your regular care. Useful questions include: Is there a placebo group? Will my current medications continue or change? How long is the study, and what tests and imaging are involved?
Research is not guaranteed treatment
It helps to keep realistic expectations. A study treatment is not yet proven, so it may not help, and many RA trials include a placebo or active-comparison arm. Because RA treatments affect the immune system, some studies have specific rules about pausing or continuing medications. Do not stop or change your DMARDs, biologics, or other RA medications to qualify for a study without your rheumatologist’s guidance. Stopping treatment abruptly can trigger flares and joint damage.
What taking part usually involves
Details vary, but joining an RA trial often begins with a screening visit to confirm eligibility — which may include joint exams, blood tests, imaging such as X-rays or ultrasound, and infection screening — followed by scheduled visits over months. You may complete questionnaires about pain, stiffness, and daily function, and researchers may score joint swelling and tenderness. Interventional trials frequently use randomization (assignment by chance to a treatment or comparison group) and blinding (where you, and sometimes the team, do not know your assignment) so results are less biased. Knowing this structure in advance helps you plan around visits and understand why certain tests are repeated over time.
Safety, eligibility, and who should be cautious
Eligibility may depend on how long you have had RA, disease activity, prior treatments, other health conditions, infections (including latent tuberculosis or hepatitis), current medications, and pregnancy status. Because many RA drugs suppress the immune system, screening for infection is common, and some studies exclude pregnancy or certain conditions for safety. Institutional Review Boards oversee trials to help protect participants. Be cautious of any program that charges high fees for unproven “cures” or pressures you to abandon proven care. Keep your rheumatologist informed and bring a current medication list to every visit.
Frequently asked questions
Can I join a trial if my RA is well controlled?
Sometimes. Some studies enroll people in remission or on stable treatment (for example, tapering studies), while others seek people with active disease. Check each listing’s criteria.
Are rheumatoid arthritis trials free to join?
Study procedures and any investigational treatment are typically provided at no cost, and some reimburse travel. Confirm with the study team.
Will I have to stop my current biologic?
It depends on the protocol. Some require a washout period; others do not. Never change medication on your own — only with your rheumatologist and the study team.
Might I receive a placebo?
Possibly, in some randomized trials, though many use an active comparison alongside standard care. The consent form explains the design.
How do I know a trial is legitimate?
Legitimate studies are usually registered on ClinicalTrials.gov and overseen by an ethics board. Be wary of programs that charge for an unproven “cure.”
Where can I learn more about managing RA?
