How many stem-cell trials for Rheumatoid Arthritis are recruiting right now?
8 of 44 registered studies were open to enrolment in the 2026-08-29 snapshot — 18% of everything ever registered for this condition with a stem-cell intervention.
Who these studies will actually take
Trials require active disease by a composite score despite methotrexate or biologics, with serology and imaging documentation. Well-controlled patients are excluded, so the enrolled population is refractory and harder to treat than the average enquirer.

What recruiting does and does not mean
A recruiting flag says a protocol cleared ethics review and enrolment is open. It says nothing about earlier results, nothing about your eligibility and nothing about price, because trials are not a purchase channel. Stale flags are common, so contact the listed coordinator rather than trusting the status field.
Sites sit in 27 countries, led by United States. Travelling for a trial rarely works unless the site has confirmed in writing that it can enrol non-residents and fund the follow-up schedule.

Frequently asked
How many stem-cell trials for Rheumatoid Arthritis are recruiting right now?
8 of 44 registered records (2026-08-29).
Can I join one of these trials?
Eligibility is decided by the protocol, not by willingness to pay. Read the inclusion and exclusion list on the registry record, then contact the coordinator named there.
Do trials charge participants?
Trial participation is normally free of charge for the intervention under study; some studies even reimburse travel. Payment demands invert that relationship and should stop the conversation.
