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   43874   clinical trials with a EudraCT protocol, of which   7294   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.

    General information about the trial
    Main objective of the trial
    - Assess the change in the disease diary score after 3-4 months of open-label administration of anakinra/Kineret. This score is derived from the daily questionnaire filled out by the patient or patient’s parent(s). - Assess the change in SAA levels before and after 3-4 months of drug treatment - Assess the change in SAA levels after drug withdrawal of 7 days - Evaluate the safety of using anakinra/Kineret in patients with NOMID
    Protection of trial subjects
    The study was performed in accordance with the ethical principles that have their origin in the Declaration of Helsinki and that are consistent with International Conference on Harmonization/Good Clinical Practice (ICH/GCP) and applicable regulatory requirements and NIH guidelines.

    Recruitment
    Recruitment details
    Patients were recruited from a pool of genetically tested NOMID/CINCA patients at NIH, physicians who referred NOMID/CINCA patients to NIH, and by advertising at pediatric rheumatology meetings and via the parent organization for NOMID/CINCA. Given the rarity of the disease, the study comprised the major part of North American NOMID/CINCA patients.

    Pre-assignment
    Screening details
    The enrollment/observation phase lasted for up to 3 weeks to determine main baseline characteristics. If eligible, the patient was started on an open-label administration of Kineret at 1-2 mg/kg/day by s.c. injections.

    The initial dose of Kineret given was 1-2 mg/kg body weight per day. First evaluation of the clinical response was done 1-3 months after initiation. At intervals no less than 7 days, a patient who was not in clinical remission could continue to have his/her Kineret dose increased in increments between 0.5 and 1 mg/kg to a maximum dose of 10 mg/kg per day to achieve clinical remission.

    Change in DSSS (fever, rash, joint pain, vomiting, and headache) from baseline to Month 3-6
    End point description
    Diary Symptom Sum Score The severity of the main symptoms of the disease were scored on a scale from 0 (no symptoms) to 4 (highest severity) on a daily basis using a diary. Five key symptoms were included in the primary variable DSSS: fever, headache, rash, joint pain, and vomiting. Each of the diary variables was evaluated as a mean value for a period preceding the visits. The baseline value was the mean value of the 5-30 last days before the first dose of Kineret. For the subsequent visits, the mean value of the last 30 days with data before each visit was used as the response variable. Arithmetic mean is based on change from baseline to Month 3 and statistical analysis is based on change from baseline to Month 3-6.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    04 Nov 2003
    Main changes in study plan: Repeat lumbar punctures and extension of the open-label treatment period. Reason for change/Comment: No placebo available at the time of first patient reaching 3 months
    23 Dec 2003
    Main changes in study plan: The randomized double-blind withdrawal period, was replaced by an open-label withdrawal in all patients. Change in primary objective and definition of flare. Reason for change/Comment: Placebo could not be obtained so the withdrawal phase was changed to an open-label withdrawal of study drug in all patients. The withdrawal period reduced to 7 days to limit the untoward effects for the patients to a minimal period of time.
    04 Mar 2004
    Main changes in study plan: Move some tests from visit Month 3 to Month 6. Allow more flexibility in scheduling follow-up appointments. Reason for change/Comment: Due to the withdrawal of treatment early during the Month 3 visit it was not possible to do all the examinations before that and it was not of value to do the exams when off treatment (the intention was to study the drug effects)
    15 Jun 2004
    Main changes in study plan: The withdrawal phase was removed after completion of 11 patients. Reason for change/Comment: Because of the significance of the study drug treatment effects in the first 11 patients and the severity of their flares upon withdrawal, the withdrawal phase was removed.
    12 Nov 2004
    Main changes in study plan: Study prolonged and patients who complete the Month 12 evaluation were eligible for continued treatment for an additional year (visits at 18 and 24 months). Maximum allowed dose 3mg/kg/day Reason for change/Comment: To allow patients to continue treatment and for individual dosing above 2 mg/kg/day
    10 Mar 2007
    Main changes in study plan: An open-ended extension was added to the study and allowed for continued evaluation. Patients were to return to the NIH every 6 months for evaluation and had monthly visits to the local physician in between. The maximum dose allowed was increased to 5 mg/kg/day. The possibility to transfer eligible NOMID patients included in other research projects at the NIH to one protocol. The possibility to recruit more patients. PK sampling and method of calculation adjusted. Reason for change/Comment: The focus of the study was modified from short term effects to long term effects in organ disease manifestations to determine if treatment could prevent the occurrence or progression of organ damage. The primary objective did however not change. To allow for individual dosing above 3 mg/kg/day
    11 Jun 2007
    Main changes in study plan: Removal of age limit. Reason for change/Comment: The treatment outcome at this time point indicated slowed progression of organ damage. It was therefore of great interest to start treatment at the earliest age to evaluate whether organ damage could be completely prevented.
    03 Mar 2009
    Main changes in study plan: Other IL-1 receptor antagonist drugs were allowed as treatment in the study. (This allowance was removed in the September 10, 2010, amendment) Reason for change/Comment: To be able to evaluate the effects of other IL-1 blockers under the same investigational protocol
