Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Hospitals and clinics in Japan

Description

Inclusion criteria

  • Participants with rheumatoid arthritis
  • Participants who take iguratimod

Exclusion criteria

  • Participants registered for this survey previously
  • Pregnant women or women suspected of being pregnant
  • Participants with a serious liver disorder
  • Participants with peptic ulcer
  • Participants with known hypersensitivity to iguratimod or any of its excipients

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

Design Details

  • Observational Models: Case-Control
  • Time Perspectives: Prospective

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Iguratimod
Drug: Iguratimod

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Disease Activity Score (DAS28) for Rheumatoid Arthritis (EULAR Response Criteria)
Time Frame: 52 weeks (0-24 weeks and 25-52 weeks)

DAS28 is a quantitative tool used to measure and monitor disease activity and treatment of rheumatoid arthritis. DAS28 uses a formula that includes the number of tender joints and swollen joints for a maximum of 28 joints.

DAS28 is used to assess whether an individual participant has a significant improvement of the disease activity, compared to baseline.

  • Good response: Baseline DAS28 less than or equal to 3.2 (low disease activity); DAS28 Improvement >1.2
  • Moderate response: Baseline DAS28 less than or equal to 3.2; DAS28 Improvement >0.6 and less than or equal to 1.2

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
