JAK inhibitors vs standard therapy for lung scarring in Anti-Synthetase Syndrome
This trial tests whether a new class of drugs called JAK inhibitors (which block inflammation signals) is better than a standard treatment (calcineurin inhibitors) for people with lung scarring (interstitial lung disease) caused by Anti-Synthetase Syndrome. It is for people who have not yet taken any immune-suppressing medications for this condition.

Testing a JAK inhibitor to help RA joint erosion heal
This Phase 4 study tests whether a JAK inhibitor (baricitinib) can improve how RA-related bone erosion heals. You might be eligible if you have rheumatoid arthritis that is still active despite methotrexate treatment, and you meet the specific safety and medication history rules.

Common questions
- Are there clinical trials studying JAK Inhibitor?
- Yes. Clin2 currently lists 23 recruiting studies that include JAK Inhibitor, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a JAK Inhibitor trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is JAK Inhibitor an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether JAK Inhibitor or a specific trial is right for you.
