Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. ≥ 18 years of age.
  2. Fulfills the 2010 ACR-EULAR RA classification criteria
  3. Agreement not to take traditional medicines and medications not prescribed by a doctor
  4. Adequate hematological, liver, cardiac and pulmonary function

Exclusion criteria

Exclusion Criteria:

  1. Presence of severe liver disease, class B or C.
  2. disease requiring prednisone higher than 0.5 mg/kg/day (or equivalent).
  3. Subjects unwilling to participate in an extended safety monitoring period (LTFU protocol)
  4. History of a infection (including sepsis, pneumonia, bacteremia, fungal, viral and opportunistic infections) within 4 weeks prior to first dose of study drug which in the opinion of the Investigator may compromise the safety of the subject in the study.
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Child-Pugh class

A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Oct 2025 (actual). Primary completion is estimated for Mar 2027, 17 months after the start.

Of 128 industry-sponsored phase 1 interventional studies under Arthritis, Rheumatoid, half reached primary completion within 13 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 32. This study's planned 17 months is above that.

Counting every sponsor, half of 148 studies reached it within 16 months; a quarter within 5 and three quarters within 32.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 8, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
