Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   43871   clinical trials with a EudraCT protocol, of which   7290   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    Recruitment
    Recruitment details
    This study evaluated the efficacy and safety of belimumab compared with placebo in adult participants with Systemic Lupus Erythematosus (SLE). This was a multicenter study conducted at United States (88 centers), United Kingdom (6), South Africa (5), France (4), Columbia (6) and Brazil (18).

    Pre-assignment
    Screening details
    A total of 503 participants were randomized of which 496 received at-least one dose of study medication during double-blinded phase (7 participants were randomized but not treated as they were randomized in error). A total of 359 out of 373 participants who completed double-blinded phase opted to continue optional open-label (OL) extension phase.

    In double-blinded (DB) phase, participants received matching placebo to belimumab administered as intravenous (IV) infusion plus standard of care through 52 weeks. In OL phase, participants received belimumab 10 milligram per kilogram (mg/kg) administered as IV infusion plus standard of care every 28 days from Week 52 through Week 76.

    Placebo was supplied in a 20 milliliters (mL) vial and prepared as a sterile and lyophilized product. Upon reconstitution with 4.8 mL sterile water for injection (SWFI), each vial contained 0.16 milligrams (mg)/milliliter (mL) citric acid, 2.7 mg/mL sodium citrate, 80 mg/mL sucrose, 0.4 mg/mL polysorbate 80, potential of hydrogen ions (pH) 6.5. Each lyophilized vial was for single use.

    End point description
    SRI response is defined as >=4 point reduction, from Baseline in safety of estrogen in Lupus National Assessment(SELENA)SLEDAI[SS] score (with modified SLEDAI-2K scoring for proteinuria [PU]), no worsening (increase of <0.30 points from Baseline) in Physician's Global Assessment (PGA) and no new British Isles Lupus Assessment Group of SLE clinics(BILAG)A organ domain score [ODS] or 2 new BILAG B ODS compared with Baseline. Analysis performed for comparison between belimumab and placebo with covariates treatment group, Baseline SS score, Baseline complement levels and region. The Modified Intention-To-Treat (mITT) population comprised of safety population excluding participants who had any assessment at 3 sites (202196, 202513 or 107286). One participant in the mITT population Belimumab 10 mg/kg arm did not have a screening or Baseline PGA assessment; therefore, this participant did not contribute to the SRI/component analysis.

    End point description
    SRI response is defined as >=4 point reduction, from OL Baseline in SS score (with the modified SLEDAI-2K scoring for PU), no worsening (increase of <0.30 points from OL Baseline) in PGA and no new BILAG A ODS or 2 new BILAG B ODS compared with OL Baseline. mITT OL population comprised of Intent-to-Treat (ITT) OL population (all randomized participants who received at least one dose of OL treatment) excluding participants who had any assessment at 3 sites (202196, 202513 or 107286). For participants switching from placebo to belimumab 10 mg/kg IV in the open-label phase, Baseline was defined as the last assessment at the end of the double-blind phase (i.e. Week 52) pre-OL treatment. For participants that received belimumab 10 mg/kg IV during the double-blind phase and continued to receive belimumab 10 mg/kg IV during the open-label phase, Baseline was defined as Day 1 of the double-blind phase. Only those participants with data available at the specified data points were analyzed.

Drop-outs and Treatment failures were set to non-responders. Analysis was performed using a logistic regression model for the comparison between belimumab and placebo with covariates treatment group, Baseline SS score (<=9 vs. >=10), Baseline complement levels (low C3 and/or C4 vs. no low C3 or C4) and region (US/Canada vs. Rest of World). One participant in the mITT population Belimumab 10 mg/kg arm did not have a screening or Baseline PGA assessment; therefore, this participant did not contribute to the SRI/component analysis.

Analyses of severe SLE flare was performed on modified SS SLE flare index that excludes severe flares (SF) that were triggered only by an increase in SS score to >12 (this may only represent a modest increase in disease activity). Treatment failures were imputed as SF. Only post-Baseline SF were considered. Analysis was performed using Cox proportional hazards model for the comparison between belimumab and placebo adjusting for Baseline SS-S2K score (<=9 vs. >=10), baseline complement levels (at least 1 C3/C4 low vs. no C3/C4 low), and region (US/Canada vs. Rest of World).

    Average (avg.) daily prednisone (PRED.) dose was calculated taking into account all steroids taken intravenously, intramuscularly, subcutaneously, intradermally and orally for both Systemic Lupus Erythema (SLE) and non-SLE reasons. A responder was defined as having a PRED. reduction [REDN.] by >=25% from Baseline to <=7.5 mg/day during Weeks 40 through 52. At Baseline, the avg. daily prednisone dose [PD] was the sum of all PDs over 7 consecutive days [excluding Day 0], divided (DIV.) by 7. For analysis, the avg. PD was the total PD during Weeks 40 through 52 DIV. by the number of days during Weeks 40 through 52. Analysis was performed using a logistic regression model with covariates treatment group, Baseline PD, Baseline SS-S2K score, (<=9 vs >=10), Baseline complement levels (low C3 and/or C4 vs. no low C3 or C4) and region (US/Canada vs. Rest of World). Only those participants with Baseline prednisone dose >7.5 mg/day were included.

    End point description
    Average daily prednisone dose was calculated taking into account all steroids taken intravenously, intramuscularly, subcutaneously, intradermally and orally for both SLE and non-SLE reasons. A responder was defined as a participant who decreased their daily prednisone dose to <=7.5 mg/day from an OL Baseline dose >7.5 mg/day. The OL Baseline was defined as the last available value prior to the initiation of treatment with belimumab. The average daily prednisone dose was the sum of all PDs over 7 consecutive days including OL Week 28 divided by 7. Only those participants with data available at the specified data points were analyzed.
