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   42567   clinical trials with a EudraCT protocol, of which   7008   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    MedDRA Classification
    E.1.3Condition being studied is a rare disease Yes
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To evaluate the efficacy of soraprazan in reducing the amount of lipofuscin in
    RPE cells of subjects with Stargardt disease by assessing the change in
    quantitative auto-fluorescence (qAF8) from baseline to after treatment with
    soraprazan compared to placebo for up to 12 months.
    E.2.2Secondary objectives of the trial
    To evaluate the efficacy of soraprazan in reducing the amount of lipofuscin in
    RPE cells of subjects with Stargardt disease by assessing the change in
    quantitative auto-fluorescence (qAF8) from baseline to after treatment with
    soraprazan compared to placebo for up to 24 months.
    To assess the safety and efficacy of soraprazan based on safety parameters
    and secondary efficacy parameters such as change in visual function and
    structural changes after treatment with soraprazan compared to placebo for
    up to 24 months.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    In order to participate in the study, subjects must meet all of the following
    inclusion criteria:
    • Elevated qAF in at least one eye at screening (value ≥300 Units).
    • Male or female of any ethnicity and ≥ 18 years old.
    • Onset of STGD disease before the age of 45 years
    • Visual acuity of the study eye: BCVA 0.2-0.8 (decimal unit).
    • Clinical diagnosis of typical autosomal recessive Stargardt’s macular dystrophy (STGD1).
    • Genetic report indicating at least two ABCA4 mutations (one with confirmed pathogenesis by a certified lab, one reported previously).
    • Study eye must have clear ocular media and adequate pupillary dilation, including no allergy to dilating eye drops and with sufficient fixation to permit good quality retinal imaging.
    • Able and willing to comply with study requirements, restrictions and instructions and is likely to complete the study.
    • Signed and dated informed consent form.
    • Female subjects of childbearing potential and male subjects participating in the study who are sexually active must use acceptable contraception from screening and until one month after intake of the last IMP dose. Male and female subjects documented as being of non-child bearing potential (e.g. infertile, surgically sterile, postmenopausal) are exempt from the contraceptive requirements.
    • Willing to avoid excessive exposure to sun light (e.g. by using a hat, UV absorbing sunglasses and sunscreen with an SPF of 30 or more over the exposed skin).

    Note: For the purpose of this study acceptable contraception is defined as:
    a) oral, injected, transdermal or implanted hormonal methods of contraception; or
    b) placement of an intrauterine device (IUD) or intrauterine system (IUS); or
    c) barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository

    E.4Principal exclusion criteria
    In order to participate in the study subjects must not meet any of the following exclusion criteria:

    • Intolerance to acid pump antagonists (APAs).
    • Hypersensitivity to soraprazan or to any of the excipients.
    • Intake of prohibited medications/supplements (supplements containing vitamin A or beta-carotene, medications to treat any liver disease, or oral retinoid medications) within 28 days prior to screening and throughout the study.
    • Intake of other drugs with a pH dependent absorption, e.g. ketoconazole.
    • Breastfeeding, pregnant, or positive urine pregnancy test at screening or visit 2 (first intake of Investigational Medicinal Product (IMP)).
    • At screening, clinically significant abnormal haematology or biochemistry findings. Levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and/or total bilirubin >1.5 x ULN (upper limit of normal) at screening will lead to exclusion.
    • Acute or unstable severe disease or history of disease which in the opinion of the investigator would preclude participation in the study.
    • Active or history of an additional ocular disorder in the primary study eye that, in the opinion of the investigator, may confound the study results. These include, but are not limited to, any reason that might interfere with the imaging techniques used in the study (such as optic media opacity or poor pupil dilatation), inflammatory eye disease, other retinal disorders besides STGD, confirmed glaucoma or baseline intraocular pressure of ≥25mmHg, optic neuritis, high myopia (>8D spherical equivalent), amblyopia.
    • Intraocular surgery or injections in the primary study eye within 180 days of the screening visit.
    • Clinically significant abnormal electrocardiogram (ECG), or a corrected QT interval (QTc) of ≥450 ms in males or ≥470 ms in females.
    • Participation in any other investigational clinical trials within 28 days of the screening visit.
