NCT00520572
First received: August 22, 2007
Last updated: January 31, 2013

  Purpose

The purpose of this study is to confirm that AZD9056 is effective in treating rheumatoid arthritis with regard to signs and symptoms and to determine what dose is favourable over a 6-month treatment period. Patients will receive background treatment with either Methotrexate or Sulphasalazine

Primary Purpose: Treatment
Official Title: A Randomised, Double-Blind (With Open Comparator Etanercept Limb), Placebo-Controlled, Phase IIb, Multicentre Study to Evaluate the Efficacy of 4 Doses of AZD9056 Administered for 6 Months on the Signs and Symptoms of Rheumatoid Arthritis in Patients With Active Disease Receiving Background Methotrexate or Sulphasalazine

Primary Outcome Measures:
  • American College of Rheumatology 20 Response (ACR20) at 6 Months [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    The number of participants with greater to or equal to 20% improvement in the ACR composite score (a measure of RA symptoms including: joint swelling and tenderness; patient's assessment of pain, disease activity and physical function; physician's assessment of disease activity; and CRP) after 6 months' treatment


Secondary Outcome Measures:
  • American College of Rheumatology 50 Response (ACR50) at 6 Months [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    The number of participants with greater to or equal to 50% improvement in the ACR composite score (a measure of RA symptoms including: joint swelling and tenderness; patient's assessment of pain, disease activity and physical function; physician's assessment of disease activity; and CRP) after 6 months' treatment.

  • American College of Rheumatology 70 Response (ACR70) at 6 Months [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    The number of participants with greater to or equal to 70% improvement in the ACR composite score (a measure of RA symptoms including: joint swelling and tenderness; patient's assessment of pain, disease activity and physical function; physician's assessment of disease activity; and CRP) after 6 months' treatment

  • Disease Activity Score (Based on 28 Joint Count) (DAS28) at 6 Months. [ Time Frame: Baseline to 6 months ] [ Designated as safety issue: No ]
    Change from baseline in the DAS28 composite score (a measure of RA symptoms including: joint swelling and tenderness; patient's assessment of disease activity; and ESR) after 6 months' treatment. A change of zero indicates no effect of treatment and a negative change of 1.2 indicates a clinically important improvement in symptoms. (The DAS scale runs from 0 to 10, with the higher scores indicating worse RA symptoms).

  • Health Assessment Questionnaire - Disability Index (HAQ-DI) at 6 Months. [ Time Frame: Baseline to 6 months ] [ Designated as safety issue: No ]
    Change from baseline in HAQ-DI (a measure of patients assessment of physical function scored between zero and 3) after 6 months' treatment, calculated as score at 6 months minus score at baseline. A change of zero indicates no effect of treatment and a negative change of 0.22 or greater indicates an improvement in symptoms. (The HAQ-DI scale runs from 0 to 3, with higher scores indicating greater disability).
