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   43845   clinical trials with a EudraCT protocol, of which   7282   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.

    • Change from baseline in frequency of seizure activity as measured by electroencephalography (EEG) abnormalities
    • Change from baseline in cognitive function using the Cambridge Neuropsychological Test Automated Battery (CANTAB)
    • Change from baseline in distance walked as measured by 6MWT
    • Time to onset of paroxysmal exertional dyskinesia (PED) as measured during 6MWT.
    • Change from baseline in gross motor function using the Gross Motor Function Measure-88 (GMFM-88)

    4) At least 4 observable seizures (generalized [except absence] or partial-onset [simple partial motor, complex partial, or secondarily generalized] seizures) per month during the Baseline Period, with no 3-week seizure-free period during the Baseline Period
    5) Continuing to have seizures despite a prior or current use of at least 1 AED
    6) Allowed to be on 1 - 3 concomitant AEDs that must have been stable in dose at least 2 weeks prior to the beginning of screening and anticipated to remain stable in dose through the end of the 8-week, placebo-controlled Treatment Period
    7) Not on, or not fully compliant with a prescribed diet plan (e.g. ketogenic diet) comprised of at least 50% total daily caloric intake from fat during previous 60 days (confirmed by 3-day diet diary at Screening), or at any time during the course of the trial
    8) Plasma level of beta-hydroxybutyrate (BHB) ≤ 1 mmol/L (non-fasting) at Screening
    9) Naïve to triheptanoin
    10) Provide written or verbal assent (if possible) and written informed consent by a legally authorized representative after the nature of the study has been explained, and prior to any research-related procedures

    12) Females who have reached menarche must have a negative pregnancy test at Screening. If sexually active, subject must be willing to use acceptable method of contraception and have additional pregnancy tests during the study.
    E.4Principal exclusion criteria
    1) Serum alanine aminotransferase (ALT) or aspartate aminotransferase (AST) levels exceeding 2X the upper limit of normal at Screening

    7) Has a condition of such severity and acuity, in the opinion of the investigator, that it warrants immediate surgical intervention or other treatment
    8) Has a concurrent disease or condition, or laboratory abnormality that, in the view of the investigator, places the subject at high risk of poor treatment compliance or of not completing the study, or would interfere with study participation or introduces additional safety concerns (e.g., diabetes mellitus, other concurrent neurological or psychiatric disorders)
    E.5 End points
    E.5.1Primary end point(s)
    The primary efficacy evaluation is the reduction from baseline in monthly frequency of generalized or partial-onset seizures between Weeks 2 and 8. The baseline monthly frequency is defined as the number of generalized or partial-onset seizures experienced in the 6 weeks prior to randomization, normalized to a 4-week rate. The primary efficacy comparison, as well as secondary and exploratory analysis of the primary endpoint will be described in the SAP.
    E.5.1.1Timepoint(s) of evaluation of this end point
    Week 8
    E.5.2Secondary end point(s)
    The secondary efficacy analyses are primarily focused on alternative domains of Glut1 DS disease to assess the breadth of treatment effect of UX007. The secondary analyses will compare the secondary efficacy variables scores after treatment to before treatment between the treated and placebo groups. The specific tests and analyses will be defined in the SAP.
    Included in these analyses will be a predefined per protocol analysis of those subjects that achieve at least 30% of calorie intake or higher as the tolerated dose level and have received at least 80% of the expected doses, to assess whether a subpopulation of the highest dose subjects have a larger difference in efficacy.
    Each of the efficacy variables assessed at Week 52 (or Week 26 for EEG only) will be compared to the value obtained at the baseline visit (or screening visit if not performed at the baseline visit) utilizing the same statistical test as conducted at the Week 8 analysis, but adjusted for the difference that the analyses for the Week 52 data will only utilize a within-cohort comparison and not a between-cohort comparison.
    Change-from-baseline values (where applicable) will be provided for the following secondary efficacy variables at baseline and Week 8:
    • The reduction from baseline to Week 8 in frequency of generalized tonic-clonic seizures.
    • Seizure response rate, defined as the percentage of subjects with at least 50% reduction from baseline in generalized or partial-onset seizures.
    • The change from baseline to Week 8 EEG abnormalities (including absence seizures) as determined by overnight EEG
    • The change from baseline to Week 8 in the individual scores for the CANTAB MOT, PAL, RTI, SSP and SWM tests.
    • The change from baseline to Week 8 6MWT distance and percent of predicted 6MWT distance.
    • Time to onset of PED during 6MWT.
    • The change from baseline to Week 8 in the GMFM-88 total score and 5 domain scores.
