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   43865   clinical trials with a EudraCT protocol, of which   7286   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 ).

    General information about the trial
    Main objective of the trial
    In the European Union (EU) and rest of world, efficacy of UX003 in mucopolysaccharidosis VII MPS VII subjects is determined by the percent reduction of urinary glycosaminoglycan (uGAG) excretion after 24 weeks of treatment relative to the pre-treatment baseline. In the United States (US) only, efficacy of UX003 in MPS VII subjects is based on the totality of the clinical data on a per subject basis.
    Protection of trial subjects
    The trial was designed, conducted, recorded, and reported in accordance with the principles established by the 18th World Medical Association General Assembly (Helsinki, 1964) and subsequent amendments and clarifications adopted by the General Assemblies. The investigators made every effort to ensure that the study was conducted in full conformance with Helsinki principles, International Council for Harmonization (ICH) Good Clinical Practice (GCP) guidelines, current Food and Drug Administration (FDA) regulations, EU Clinical Trial Directive 2001/20/EC, and local ethical and regulatory requirements. Each investigator was thoroughly familiar with the appropriate administration and potential risks of administration of the study drug, as described in the protocol and Investigator’s Brochure, prior to the initiation of the study. The method of obtaining and documenting informed consent and the contents of the informed consent form (ICF) complied with ICH GCP guidelines, the requirements of 21 CFR Part 50, “Protection of Human Subjects,” the Health Insurance Portability and Accountability Act regulations, and all other applicable regulatory requirements. Investigators were responsible for preparing the ICF and submitting it to the Sponsor for approval prior to submission to the Institutional Review Board (IRB). All ICFs were written in regional language and contained the minimum elements for consent as mandated by the ICH guidelines. An IRB-approved ICF was provided by the Sponsor prior to initiation of the study. Investigators obtained signed written informed consent from each potential study subject prior to the conduct of any study procedures and after the methods, objectives, requirements, and potential risks of the study were fully explained to each potential subject. Consent for participation could be withdrawn at any time for any reason by the subject.

    Percent change from baseline in uGAG DS was analyzed by GEE modeling based on observed data. The GEE model included all subjects who had non-missing baseline and at least one post-baseline value during the 24 weeks of UX003 treatment. The model included baseline value, and the UX003 treatment week as a categorical variable. The covariance structure within subjects was assumed to be exchangeable.

    Multi-Domain Responder Index (MDRI) Score at UX003 Treatment Week 24
    End point description
    The MDRI score was calculated as the total score across the following six domains (6-Munite Walk Test [6MWT], forced vital capacity predicted value [FVC% pred], shoulder flexion, visual acuity, and Bruininks-Oseretsky Test of Motor Proficiency [BOT-2] fine motor and gross motor capacity) at UX003 Treatment Week 24. MDRI was intended to capture the aggregate benefit or decline across multiple domains of clinical function or clinically important change. By reducing each individual subject’s response to either a clinically significant response (+1 minimum important difference [MID] or greater), a clinically meaningful decline (-1 MID or smaller) or no clinically significant change (>-1.0 to <1.0 MID), an interpretable composite effect of domain responses was added for each subject.

    The 3 most impactful clinical problems as reported by the subject/parent/caregiver during the Clinical Problem Evaluation were scored on a Likert scale from 1 (indicating very little problem) to 7 (indicating an extreme amount) at the randomization and post-randomization visits. At post-randomization visits, each clinical problem was again scored for impact on daily activities. The Likert score is 1=very little, 2=some, 3=a fair amount, 4=a moderate amount, 5=a considerable amount, 6=a lot, 7=an extreme amount; lower scores reflect less impact on daily life. Total scores ranged from 3 to 21. The change from baseline up to UX003 Treatment Week 24 were analyzed by GEE modeling, including baseline value, and the post-UX003 initiation treatment week as a categorical variable. The covariance structure within subjects is assumed to be exchangeable.
