A Feasibility Study Exploring the Effect of Remicade on the Disease Activity in RA Patients (Study P05417) (REQUEST)

January 2, 2017 updated by: Merck Sharp & Dohme LLC

A Feasibility Study Exploring the Effect of Remicade on the Disease Activity in RA Patients

This observational study will explore the Swedish national population of patients with rheumatoid arthritis (RA) on infliximab maintenance therapy in order to identify patients who may be eligible for a dose reduction study. Patients will be asked a variety of questions regarding their treatment dosing and disease activity, and then asked whether or not they would consider participating in a dose reduction study. Patients in this study will be described in terms of demographic and disease characteristics.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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.

Detailed Description

Already known Subjects (RA and on at least 12 months ongoing Remicade treatment) from the clinic could participate if they are eligible.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
363

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

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
Dosing Interval Between the Infliximab Infusions
Time Frame: Measured from the Remicade Questionnaire at first (and only) study visit
Patients were asked as part of the Remicade questionnaire what dosing interval they were on.
Measured from the Remicade Questionnaire at first (and only) study visit
Reason for Extending Dosing Interval
Time Frame: Measured from the Remicade Questionnaire at first (and only) study visit
Among patients who reported that they at some occasion during treatment with infliximab had a longer dosing interval than every 8 weeks, the reason for extending dosing interval was asked of each patient.
Measured from the Remicade Questionnaire at first (and only) study visit
Patient Response to Increased Dosing Interval
Time Frame: Measured from the Remicade Questionnaire at first (and only) study visit
Among patients who reported that they at some occasion during treatment with infliximab had a longer dosing interval than every 8 weeks, patients were asked "did you notice any difference when your dosing interval was extended?" Those who noticed a difference were asked if their experience was positive or negative.
Measured from the Remicade Questionnaire at first (and only) study visit
Number of Patients Agreeing to Participate in a Dose Reduction Study
Time Frame: Measured from the Remicade Questionnaire at first (and only) study visit
As part of the Remicade questionnaire, patients were asked "would you consider participating in a dose reduction study?"
Measured from the Remicade Questionnaire at first (and only) study visit

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Disease Activity Score Based on Assessment of 28 Joints (DAS28), Health Assessment Questionnaire (HAQ), C-reactive Protein (CRP), Erythrocyte Sedimentation Rate (ESR), Infliximab Dosage.
Time Frame: Measured at first (and only) study visit, and outcomes measured during the two preceding physician visits are extracted from the Swedish Rheumatoid Arthritis (RA) Registry.
This is not a prespecified key secondary outcome; therefore, results will not be disclosed
Measured at first (and only) study visit, and outcomes measured during the two preceding physician visits are extracted from the Swedish Rheumatoid Arthritis (RA) Registry.
Adverse Events (AEs)
Time Frame: Collected at first (and only) study visit, all AEs reported during the previous 12 months is collected from the Swedish Rheumatoid Arthritis (RA) Registry.
This is not a prespecified key secondary outcome; therefore, results will not be disclosed
Collected at first (and only) study visit, all AEs reported during the previous 12 months is collected from the Swedish Rheumatoid Arthritis (RA) Registry.
Duration of Subject's Rheumatoid Arthritis (RA) Diagnosis, European Quality of Life Group 1990 5 Dimension (EQ5D) and Patient Remicade Questionnaire.
Time Frame: Measured at first (and only) study visit, and outcomes measured during the two preceding physician visits are extracted from the Swedish Rheumatoid Arthritis (RA) Registry.

Study Start

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.
