Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   35419   clinical trials with a EudraCT protocol, of which   5814   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).

    Recruitment
    Recruitment details
    Children aged 6 months to < 5 years old with neurogenic detrusor overactivity (NDO) were enrolled from Belgium (1 site), United Kingdom (1 site), Poland (2 sites), United States (1 site), the Philippines (1 site) and South Korea (2 sites).

    Pre-assignment
    Screening details
    Children who met the eligibility criteria were treated with sequential doses of solifenacin up to 12 weeks to determine each participant's optimal dose, after which a fixed dose of solifenacin was given for at least 40 weeks. A washout period was required between screening and baseline if the children were being treated with antimuscarinic agents.

    Dosage and administration details
    An initial dose of solifenacin was administered on the baseline visit for children aged 6 months to < 2 years and the day after the baseline visit for children aged 2 years to < 5 years, then once daily for a 12-week Titration period, to determine the participant's optimal dose. Doses were calculated per weight determined at the baseline visit of this study and based on a physiologically-based pharmacokinetic (PK) model, targeting to have equivalent doses of 2.5, 5, 7.5 and 10 mg doses of solifenacin once daily in adults (referred to as PED2.5, PED5, PED7.5 and PED10). During the 12-week Titration period, the dose of solifenacin was down-titrated, up-titrated or maintained depending on the study’s titration criteria, which were based on a combination of diary endpoints, urodynamic assessments and adverse event (AE) criteria.

    Change from Baseline to Week 24 in Maximum Cystometric Capacity (MCC) [1]
    End point description
    MCC was the volume instilled into the bladder prior to leakage or end of bladder-filling (whichever was reached first), as assessed by urodynamics (procedure: the bladder was to be filled until voiding/leakage began, or until it was stopped because either the participant experienced pain or discomfort or 135% of expected bladder capacity [EBC] was reached for participants ≥ 2 years or of maximum catheterized volume [MCV] for participants aged 6 months to <2 years; the participants' bladder was emptied via catheterization).

    End point description
    Participants were required to have 4-6 CICs per day on a schedule fixed for the duration of the study. To calculate the number of periods between CICs with incontinence in a diary day, the diary day was divided into periods between CICs (i.e. inter-CIC periods). The hour period, rather than the exact time, of each CIC and incontinence episode was recorded in the diary. When an incontinence episode and a CIC were marked in the same hour period, the incontinence episode was counted as occurring prior to the CIC (when the bladder had not yet emptied), rather than after it (when the bladder had recently been emptied), i.e. the inter-CIC period ended with the hour in which the CIC was recorded. The mean number of periods between CICs with incontinence per 24 hours was the number of periods between CICs when incontinence occurred, divided by the total number of valid diary days. FAS population. "N" is the number of participants with available data at baseline and each time point.

    Percentage of Days with Incontinence for Each Hour of 24 Hour Day During Week 36
    End point description
    Incontinence was defined as leakage where a diaper is not used, or dampness where a diaper is used. For each one hour period of the 24 hour day, the incidence of incontinence was assessed as the number of days with incontinence occurring within the one hour period divided by the number of valid diary days over all participants. Each participant contributed to up to three days of valid diary data for each visit. The analysis population was FAS. The number of valid diary days was 60.

    End point description
    The ITQoL SF-47 consisted of 47 individual items and was filled in by the child’s parent. The individual items are based on Likert scales with either 5 responses (coded as 1 through to 5) or 4 responses (coded as 1 through to 4). Before calculating a scale, the value of each item is coded so that it ranges from 0 (worst possible) to 100 (best possible). From subsets of these coded values, 11 scales are derived: overall health, physical activities, development, discomfort, moods and temperaments, perceptions of current past and future health and perception of changes. The analysis population was FAS. "N" indicates the number of participants with available data at baseline and at each time point.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    24 Jun 2014
    Changes summarized: ● Change in the planned study period: the duration of the study was increased from 4Q2014 to 3Q2015. Recruitment timeframe was extended to include children under the age of 2 years. ● Change in the dosing rationale: the model used to select the drug dose was updated to a PBPK model to account for age-related physiological changes in clearance and distribution processes. ● Adjustment in the automated dose volume: the volume of medication was adjusted at visit 7 and 8 if any change in weight placed the patient in a new category. The dose volume was adjusted to ensure that patients were being treated effectively as weight in young infants could have increased substantially during the study. ● Added optional unscheduled urodynamic evaluation: new unscheduled urodynamic assessment was permitted 3 weeks after visit 6 (week 12). This evaluation allowed the investigator to confirm that the balance of efficacy and symptoms of intolerability had been established for patients who have had their dose adjusted at visit 6. ● Revised calculation of baseline mean QT interval corrected for heart rate by Bazett’s formula (QTcB): new calculations included the averages of the QTcB mean from visit 1 and 2. Previous calculations used only the QTcB mean from visit 2. This revision was done as statistical analysis of the intra-patient variation in baseline QTcB between visit 1 and visit 2 showed that a more precise estimate of QTcB could be obtained using the measurements from both visits. ● Addition of medical assessment of safety profile of children: New assessment used descriptive statistics rather than formal statistics comparisons given that only a small number of patients under the age of 2 years enrolled. ● Change in the lower age range of patients: the lower age limit was decreased from 2 years to 6 months. The inclusion of children from 6 months of age aligns the study with the approved PIP for solifenacin (EMEA-000573-PIP01-09).
