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   43440   clinical trials with a EudraCT protocol, of which   7185   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
    		 Subjects were randomized to receive 600mg risankizumab, 1200mg risankizumab or placebo during the double-blind, placebo-controlled Period 1. At Week 12, subjects who do not achieve clinical response were randomized into Period 2 to receive 180mg risankizumab, 360mg risankizumab or 1200mg risankizumab. Subjects who received placebo received 1200mg.

    Pre-assignment
    Screening details
    		 A total of 618 subjects were enrolled and 605 were included in the intent-to-treat (ITT) population; 569 of those had a baseline eligible Simple Endoscopic Score for Crohn's disease (SES-CD) of ≥ 6 (≥ 4 for isolated ileal disease) excluding the narrowing component and were included in the ITT1A population.

    		 Change from baseline in Work Productivity and Impairment Questionnaire – Crohn's disease (WPAI-CD) Overall Work Impairment at Week 12
    End point description
    WPAI: CD is a questionnaire used to evaluate lost productivity due to CD ; scores are presented as percentages (multiplying the scores by 100), with 0% representing no impact on productivity and 100% representing complete impact on productivity. Total work productivity impairment takes into account both hours missed due to CD symptoms and the patient's assessment of the degree to which CD affected their productivity while working (overall work impairment [OWI]). WPAI outcomes are expressed as impairment percentages, with higher numbers indicating greater impairment and less productivity. Intent to Treat 1A Population: all randomized subjects who received at least one dose of study drug during the 12-Week Induction Period and had baseline eligible SES-CD of ≥ 6 (≥ 4 for isolated ileal disease) excluding the narrowing component.

    05 Jul 2017
    Major changes included: Added CDAI criteria to the inclusion criteria. Updated to instruction on which hematocrit (Hct) value to use in calculating the CDAI for inclusion. Added "psychological or psychiatric cause" to exclusion criterion 29. Updated overall study design and plan: description, of study schematic figure, to remove reference to Weeks 2 and 6. Updated discontinuation of individual subjects, for subjects who do not have clinical response at Week 12. Updated contraception recommendations, and exclusion criterion 28. Updated pregnancy, for pregnancy reporting timing. Clarified the blind-breaking process. Updated tuberculosis (TB) requirements in exclusion criteria, benefits and risks, and efficacy and safety measurements assessed and flow chart. Added assent information for subjects less than 18 years old. Clarified stratification criteria.
    29 Sep 2017
    Major changes included: Added an anaphylaxis adjudication committee. Revised to allow for local regulations for the difference in minimum age for adults. Updated exclusion criterion 18 for CD related complications. Updated prohibited medications. Added international normalized ratio (INR) and anaphylaxis testing. Added endoscopic remission to ranked secondary endpoints and Patient Global Impression of Severity (PGIS) and Patient Global Impression of Change (PGIC) to non-ranked secondary endpoints. Added clinical and endoscopic remission over time as endpoints. Updated criteria for discontinuation of individual subjects. Revised to reduce redundancy. Revised to align with common toxicity criteria for adverse events (CTCAE) grading criteria for adverse events (AE)s. Revised to allow for additional types of anaphylactic reactions and to provide investigators with guidance on reporting of events. Updated alignment with template requirements and for consistency across the risankizumab programs. Clarified sample size calculations. Updated to reflect the most recent subject diary entries and addition of patient-reported outcome (PRO) for collection. Updated the schedule of activities to reflect changes made in the body of the protocol. Added information on the sample collection schedule. Revised to align with regulatory agency feedback.
    09 Jul 2018
    Major changes included: Extension of the AE collection period duration, final follow-up call, and period for prohibition of vaccines. Modified benefits and risks to align with the IB. Added blood collection for tryptase following a suspected drug administration hypersensitivity reaction. Added "worsening" CD to common AEs associated with underlying disease. Added "intramuscular" as possible route of administration for prohibited anti-infectives. Exclusion of subjects who receive exclusive enteral nutrition to treat CD. Added height measurement for pediatric subjects. Prohibition of local, routine testing for fecal calprotectin (FCP) and high-sensitivity C-reactive protein. Modified contraception language. Modified statistical methods for secondary endpoints to align with regulatory feedback. Removed stool sample collection for FCP at screening. Clarified repeat screening tests and the qualifications for a screening period extension. Documentation of the DMC opinion to continue the trial and pediatric enrollment. Clarified language to allow repeat testing if screening and baseline testing were more than 14 days apart and the circumstances that would qualify for a screening period extension. Clarified that indeterminate tuberculosis (TB) test results must be repeated.
    22 Feb 2019
    Major changes included: Documentation of the data monitoring committee (DMC) opinion to continue the trial and enroll 16 17 year olds. Added language to allow single repeat testing of transient exclusionary laboratory values during the screening period. Clarified the types of prohibited corticosteroids. Modified to permit enrollment of not more than 20% subjects with prior exposure, including intolerance or inadequate response, to ustekinumab. Specified that enrollment of subjects with Baseline SES-CD of ≥ 3 to < 6 for ileocolonic or colonic disease or Baseline SES-CD of 3 for isolated ileal disease, excluding the narrowing component, would be no more than 10% of the total population. Added of stratification factor of Baseline SES-CD. Updated definitions of endoscopic remission and endoscopic response. Revised to allow a commercially available assay to determine approved biologic washout. Clarified that TB prophylaxis is permissible. Revised the order and addition of ranked secondary endpoints, update of ranked secondary endpoints to non-ranked secondary endpoints, and addition of non-ranked secondary endpoint.
