Primary Outcome Measures:
  • Change in Disease Activity Score (DAS28CRP) in cetrorelix group versus placebo group [ Time Frame: From baseline to day 5 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Change in DAS28 (CRP/ESR) [ Time Frame: From baseline to day 2/5 /10/15 ] [ Designated as safety issue: No ]
  • Change in anti-CCP level [ Time Frame: From baseline to day 2/5/10/15 ] [ Designated as safety issue: No ]
  • Change in cytokine level [ Time Frame: From baseline to day 2/5/10/15 ] [ Designated as safety issue: No ]
  • Change in ACR core set measures [ Time Frame: From baseline to day 2/5/10/15 ] [ Designated as safety issue: No ]
  • Proportion of patients with ACR 20/50/70/90 and EULAR good/moderate/none responders [ Time Frame: Baseilne to day 2/5/10/15 ] [ Designated as safety issue: No ]
  • Adverse events [ Time Frame: Baseline up to day 15 ] [ Designated as safety issue: Yes ]
    Number of patients with adverse events (and serious adverse events) up to day 15 in each group

  • Proportion of patients with DAS28low disease activity/remission [ Time Frame: Baseline to day 2/5/10/15 ] [ Designated as safety issue: No ]
  • Change in HAQ scores [ Time Frame: From baseline to day 5/10/15 ] [ Designated as safety issue: No ]
  • Correlation between percent changes in hormones, disease activity and biomarkers [ Time Frame: By day 2, 5, 10 and 15 ] [ Designated as safety issue: No ]
    This endpoint is not directly related to clinical efficacy. Hormones include LH, FSH, oestradiol, testosterone,and cortisol. Biomarkers include immunologic markers, bone markers and cardiovascular markers. This secondary endpoint was sent to authorities during the study before unblinding.
