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   44376   clinical trials with a EudraCT protocol, of which   7389   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.

    Percentage of Participants who Achieved a Systemic Lupus Erythematosus (SLE) Responder Index (SRI)-4 Composite Response at Week 24
    End point description
    SRI-4 measures reduction in SLE disease activity and was composite measure that included SLE Disease Activity Index (SLEDAI-2K), British Isles Lupus Activity Group (BILAG) and Physician Global Assessment (PGA). SRI-4 response: >=4-point reduction from baseline (BL) in SLEDAI-2K score, no new BILAG A or >1 new BILAG B (score A: severe disease; B: moderate disease), and no worsening in PGA (PGA <10% increase from BL). Composite response: SRI-4 response in participants who did not meet treatment failure criteria. SLEDAI-2K: assesses improvement in disease activity (ranged:0-105; higher score=higher severity). BILAG: assesses disease extent, severity (A[severe]-E[no disease]). PGA: assesses worsening in participant's health, recorded on visual analogue scale (VAS) with responses for disease activity ranged 0(none)-3(severe); higher score=higher disease activity. Full analysis set (FAS): all randomized participants who received at least 1 dose (partial/complete) of any study intervention.

    Percentage of participants with baseline active mucocutaneous lupus manifestations (CLASI activity score >=6) achieving >=50% reduction in CLASI activity score at Week 24 was reported. CLASI assess disease activity and damage caused to skin for cutaneous lupus erythematosus patients with/without systemic involvement across 13 body areas. CLASI consisted of 2 scores; (1) Activity Score (ranged: 0-70) (2) Damage Score (ranged: 0-56). Activity was scored by the investigator based on erythema (0-3 per area), scale/hyperkeratosis (0-2 per area), mucous membrane involvement (0-1), acute hair loss (0-1) and non-scarring alopecia (0-3). Damage was scored in terms of dyspigmentation (0-2 per area), scarring (0-2 per area), scarring alopecia (3 points if present), deep scarring (1 point). Scores were calculated by addition based on the extent of symptoms. Higher scores=worse disease activity. FAS used.

    Percentage of Participants With >=4 Point Improvement From Baseline in SLE Disease Activity Index 2000 (SLEDAI-2K) at Week 24
    End point description
    SLEDAI-2K was a validated SLE activity index, based on the presence of 24 features in 9 organ systems and measures disease activity in SLE patients at the time of visit or in previous 30 days; the index was weighted according to the feature. Features were scored by assessing physician if present at the time of visit or within last 30 days, with more severe features having higher scores, and added to determine total SLEDAI-2K score, ranged: 0-105; higher scores=increased disease activity. Baseline measurement for SLEDAI-2K was defined as the closest measurement taken prior to initiation of the Week 0 study intervention administration. SLEDAI improvement was defined as a reduction from baseline in total SLEDAI-2K score. No worsening of total SLEDAI-2K from baseline was defined as a change <=0 in SLEDAI-2K score and meaningful improvement was defined as a reduction in SLEDAI-2K of 4 or more. FAS used.

    Percentage of Participants Achieving the British Isles Lupus Assessment Group (BILAG) Composite Lupus Assessment (BICLA) Response at Week 24
    End point description
    The BILAG-based Composite Lupus Assessment (BICLA) was a composite index to assess disease activity in SLE. BICLA response defined as: (1) Reduction of all baseline (BL) BILAG-2004 A to B/C/D and BL BILAG-2004 B to C/D and no BILAG-2004 worsening in other organ systems, defined by >=1 new BILAG-2004 A or >=2 new BILAG-2004 B (Score A: Severely active disease; B: Moderately active disease; C: Mild stable disease; D: Inactive now but previously active; E: Never affected). (2) No worsening from BL in SLEDAI-2K: increase from BL of >0 points in SLEDAI-2K. Increase from BL corresponds to change from BL. (3) No worsening from BL in participants’ lupus disease activity defined by increase >=0.30 points on 3-point PGA VAS. (4) No discontinuation of study intervention or use of rescue medication beyond protocol-allowed threshold before assessment. If any of the conditions cannot be evaluated at Week 24 (due to missing values) the participant was defined as BICLA non-responder. FAS was used.

    End point description
    Time to first flare: Time to first occurrence of a flare. Flare was defined as at least 1 new BILAG A item score or at least 2 new BILAG B item scores meeting at least 1 of following criteria: 1) Not present at baseline, 2) The occurrence of a new/worse manifestation in a different component of an organ system that is already present, 3) at least 1 A or 2 B scores in an organ system which improves to B/C/D for at least 2 sequential study visits followed by new/worse disease activity. Here, score A: Severely active disease; B: Moderately active disease; C: Mild stable disease; D: Inactive now but previously active; E: Never affected. BILAG flare was based on adjudicated flare. FAS: all randomized participants who received at least 1 dose (partial or complete) of any study intervention. 99999 signifies that median, lower and upper limit of confidence interval could not be calculated due to low number of participants with event.

    Percentage of Participants who Achieved SRI-4 Composite Response at Week 52
    End point description
    SRI-4 measures reduction in SLE disease activity and was a composite measure that included the SLEDAI-2K, BILAG and PGA. SRI-4 response was defined as >=4-point reduction from baseline in SLEDAI-2K score, no new BILAG A or >1 new BILAG B, and no worsening in the PGA (PGA less than [<] 10% increase from baseline). Composite response was defined as SRI-4 response in participants who did not meet treatment failure criteria. SLEDAI-2K: assesses improvement in disease activity (ranged: 0 to 105; higher score = higher severity). BILAG: assesses disease extent, severity (range: A[severe] to E[no disease]). PGA: assesses worsening in participant's general health , recorded on a VAS with responses for disease activity ranging from 0 (none) to 3 (severe); higher score = higher disease activity. Modified full analysis set (mFAS) included all randomized participants, excluding those from Argentinian site W02-AR10008, who received at least 1 dose (partial or complete) of any study intervention.

    An adverse event (AE) was any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the intervention. Serious AE was the AE resulting in any of following outcomes/deemed significant for any other reason: death; initial/prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. TEAEs were defined as any AE occurring at or after the initial administration of study intervention. TEAEs included both serious and non-serious AEs. Safety analysis set included all randomized participants who received at least 1 dose (partial or complete) of any study intervention.
