To investigate the effect of two tight-control treatment strategies, aiming at 1) 2011 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) definition of remission compare with 2) minimal disease activity (Disease Activity Index in 28 joints [DAS28] <2.6), on arterial stiffness in early rheumatoid arthritis (RA) patients.

To compare the effect of two treatments on arterial stiffness in Early Rheumatoid Arthritis

Primary Outcome Measures:
  • The change in Alx@75 over 1-year of treatment [ Time Frame: Baseline and 12 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • The proportion of patients achieve clinical remission [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
    The proportion of patients achieve clinical remission (SDAI</= 3.3 or DAS28<2.6) after 1-year treatment

  • The proportion of patients with a good response [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
    According to EULAR definition, good response is DAS28 < 3.2 and a fall in score from baseline by > 1.2

  • ACR 20, 50, 70 responses [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
    ACR 20, 50, 70 responses defined as at least 20%, 50%, 70% improvement in joint swelling and joint tenderness counts, and three of five other variables (i.e. ESR or CRP, HAQ score, pain score and physicians' and patients' global assessments)

Estimated Enrollment: 120
Study Start Date: October 2012
Estimated Study Completion Date: October 2015
Estimated Primary Completion Date: October 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: SDAI remission group
SDAI remission
Procedure: SDAI remission
SDAI remission group aims at the 2011 ACR/EILAR definition of remission (simplified disease activity score [SDAI] <3.3)
Active Comparator: Minimal disease activity group
Minimal disease activity remission
Procedure: Minimal disease activity remission
Minimal disease activity group aims at minimal disease activity (DAS28<2.6) (minimal disease activity group)

Detailed Description:

One hundred RA patients with active disease (DAS28 >/=3.2), duration of symptoms less than 2 years, and are disease modifying anti-rheumatic drug naive will participate in this 1-year prospective, hospital-based, open-label, randomized, controlled trial.

All participants will receive 1-year tight-control treatment. One hundred patients will be randomly assigned to two arms. Treatment will be adjusted according to a standardized protocol every 3-monthly aiming at remission defined by the 2011 ACR/EULAR definition (Group 1, n=50, simplified disease activity score [SDAI] ≤3.3) or minimal disease activity (Group 2, n=50, DAS28<2.6).
