What the trial was testing
The CREDO2 enrolled 1,648 patients with rheumatoid arthritis. The study was sponsored by R-Pharm International and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was a large trial designed to confirm whether the treatment works well enough for wider use. Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
70% of olokizumab patients hit the joint improvement goal vs. 67% on adalimumab.
New England Journal of Medicine · 2022 · NCT02760407
These findings — that joint improvement (ACR20) at 12 weeks on olokizumab compared with adalimumab — were published in the New England Journal of Medicine and represent the headline result of the study.
Researchers tracked outcomes across 1,648 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with rheumatoid arthritis, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
Olokizumab is approved in Russia and a few other countries but is NOT FDA-approved in the U.S. and not available here. Several IL-6 blockers (tocilizumab, sarilumab) and TNF blockers (adalimumab, etanercept) are FDA-approved for RA. Ask a rheumatologist which approved option fits your case.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

Prognostic Factors and Predictors of Disease Flare in Patients With Rheumatoid Arthritis
The goal of this observational study is to help find better ways to predict when a flare of your disease (rheumatoid arthritis) might happen. By looking at your registered data, symptoms, disease characteristics, and specific markers in your blood, the investigators hope to help doctors make better decisions about your treatment in the future. The main question it aims to answer is: Can specific patient data, disease characteristics, drug history, or markers in a patient's blood be used to predict when a rheumatoid arthritis flare is about to happen? Participants already diagnosed with rheumatoid arthritis and who have their disease controlled will be followed up every 3 months for any signs or symptoms of a flare.
