A Feasibility Study Exploring the Effect of Remicade on the Disease Activity in RA Patients (Study P05417) (REQUEST)
2. januar 2017 opdateret af: 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.

Dosing Interval Between the Infliximab Infusions
Tidsramme: 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
Tidsramme: 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.

|
Patient Response to Increased Dosing Interval
Tidsramme: 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.
