About this study

Official title: A Retrospective Evaluation of the Radiographic Efficacy of Different Conventional Systemic Therapies and Biologics in Patients With Rheumatoid Arthritis in Routine Practice.

This study involves review and analysis of disease activity in patients with rheumatoid arthritis who where treated with either conventional DMARDs (Disease Modifying Antirheumatic Drugs) or Biologics and have two existing, consecutive radiographs (x-ray images) of hand and feet taken as part of routine treatment monitoring within a time interval of 12 to 36 months.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline in Joint Status Assessed by Radiographic (Roentgen) Progression

    Radiographic progression assessed using Ratingen score with range of 0 = normal joint; 1 = one or more erosions, <20% of the joint surface are destroyed; 2 = 21% to 40% of the joint surface are destroyed; 3 = 41% to 60% of joint surface are destroyed; 4 = 61% to 80% of the joint surface are destroyed; 5 = >80% of the joint surface are destroyed. Total possible score based on 38 joints was 0 to 190; higher scores indicated greater joint destruction. Annualized change in Ratingen score calculated as (total change in Ratingen score / time period between radiograph 1 and 2 [months])*12 months.

    Measured: Baseline (Day 0) up to 48 months

Secondary outcomes (7)
  1. Number of Participants Without Radiographic Progression

    An increase of 4 or more points in the Ratingen score was necessary to detect a difference in radiographic progression. Ratingen score range 0 = normal joint to 5 = >80% of the joint surface are destroyed. Total possible score based on 38 joints was 0 to 190; higher scores indicated greater joint destruction. A decrease of 4 (smallest detectable difference) or more points in total Ratingen score was considered a decrease in erosive damage.

    Measured: Baseline (Day 0) up to 48 months

  2. Number of Participants Without Erosions

    Radiographic assessment of no erosions using Ratingen scoring categorized as score of 0=normal joint.

    Measured: Baseline (Day 0) up to 48 months

  3. Change From Baseline in Disease Activity Score Based on 28 Joints (DAS 28)

    DAS28 calculated from the number of swollen joints (SJC) and painful joints (PJC) using the 28 joints count, the erythrocyte sedimentation rate (ESR) (millimeters per hour [mm/hour]) and patient's global assessment (PGA) of disease activity (participant rated arthritis activity assessment with transformed scores ranging 0 to 10; higher scores indicated greater affectation due to disease activity). DAS28 ≤3.2 = low disease activity, DAS28 >3.2 to 5.1 = moderate to high disease activity.

    Measured: Baseline (Day 0) up to 48 months

  4. Change From Baseline in Erythrocyte Sedimentation Rate (ESR)

    Erythrocyte Sedimentation Rate measured as millimeters per hour (mm/h).

    Measured: Baseline (Day 0) up to 48 months

  5. Change From Baseline in C-reactive Protein (CRP)

    C-reactive protein measured as milligrams per liter (mg/l)

    Measured: Baseline (Day 0) up to 48 months

  6. Number of Participants With Change From Baseline in Rheumatoid Factor (RF)

    Rheumatoid Factor measured as a titer and categorized as negative (<1:16 ratio) or positive. A ratio >1:16 indicates a higher level of RF.

    Measured: Baseline (Day 0) up to 48 months

  7. Number of Participants With Laboratory Result for Cyclic Citrullinated Peptide-autoantibody-test (CCP)

    Cyclic citrullinated peptide-autoantibody-test measured as Enzyme-linked immunosorbent assay (ELISA units or EU) and categorized as negative (<20 EU) or positive (≥20 up to >60 EU).

    Measured: Baseline (Day 0) up to 48 months

Questions about this trial

What is this clinical trial studying?

An observational study of Rheumatoid Arthritis, run by Pfizer at 1 site in Denmark.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Aug 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 28 Jun 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change From Baseline in Joint Status Assessed by Radiographic (Roentgen) Progression (time frame: Baseline (Day 0) up to 48 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Aug 2011.
