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.

    Arm description
    Single doses of AK002 were administered by IV infusion every 28 days at Weeks 0, 4, 8, 12, 16, and 20. The arm included all subjects who were enrolled, did receive at least 1 dose of study drug, and had at least 1 post-baseline assessment of the primary efficacy variable (=modified intent-to-treat population, mITT).

    Dosage and administration details
    AK002 (15 ± 1.5 mg/mL) was administered as IV infusion starting at 0.3 mg/kg on Day 1. If well tolerated, the dose was increased to 1 mg/kg on Day 29 and Day 57. The dose could be increased further to 3 mg/kg on Days 85, 113, and 141 if the UCT score was <12 and/or the Investigator, in consultation with the Allakos Medical Monitor, deemed it advisable.

    Notes
    [1] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
    Justification: 47 subjects were enrolled in this study and received at least one dose of the study drug. 45 of these subjects had at least one post-baseline assessment of the primary efficacy variable, and were reported in the baseline period.

    End point title
    Change in UCT from Baseline at Week 22 using LOCF [1]
    End point description
    The primary endpoint was the change in the UCT, a score for symptom control in chronic urticaria (CU). At Baseline, a 4-week recall was to be recorded, prior to first study drug administration. A change of the UCT score of 3 or more points was regarded as clinically relevant (minimal clinically important difference [MCID]).
    End point type
    Primary
    End point timeframe
    The change of the UCT was measured from Baseline to Week 22.
    Notes
    [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point.
    Justification: No statistical tests were performed for this pilot study. Descriptive statistics and confidence intervals were evaluated.
