Inclusion criteria

  • Treatment-naive subjects with recent onset rheumatoid arthritis
  • Signed

Exclusion criteria

Exclusion Criteria:

  • Subjects with rheumatoid arthritis symptoms other than those associated with joints at disease onset
  • Subjects with joint function impairment secondary to other conditions not associated with rheumatoid arthritis
Terms in these criteria, in plain language(1)

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.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

  1. Disease Activity Score (DAS 28 score) at week 12.

    DAS 28=(0.56√NAD+ 0.28√NAT+0.7ln⁡VSG+0.14EGE) where NAD: number of joints with pain; NAT: number of joints with increased volume; VSG: sedimentation rate of erythrocytes; EGE: Global assessment of disease by the patient on a visual analog scale (1 to 100 mm)

    Time frame: 12 weeks

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 May 9, 2011, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
