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   43801   clinical trials with a EudraCT protocol, of which   7258   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.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    • To evaluate the safety of up to 3 additional courses of oral QLT091001 administered once daily for 7 days in subjects with LCA or RP caused by RPE65 or LRAT gene mutations who have been treated previously with a single 7-day course of QLT091001 in Study RET IRD 01
    • To evaluate whether up to 3 additional courses of oral QLT091001 administered once daily for 7 days can maintain or improve visual function in subjects with LCA or RP caused by RPE65 or LRAT gene mutations who have been treated previously with a single 7-day course of QLT091001 in Study RET IRD 01
    E.2.2Secondary objectives of the trial
    Not applicable.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Subjects with LCA or RP due to RPE65 or LRAT deficiency who received a 7-day treatment course of QLT091001 and completed the Day 30 visit in Study RET IRD 01.

    2. Subjects who meet any one of the following criteria at least 1 month after the start of the 7-day treatment course in Study RET IRD 01:
    a. No increase in GVF (in at least 1 eye):i.e. follow-up GVF increased ≤20% from baseline or
    b. Decrease in GVF (in at least 1 eye): i.e. follow-up GVF decreased below the highest previous response by >20% or
    c. Considered a reasonable candidate for treatment, as determined by the Investigator based on regression or lack of response in other parameters of visual function (e.g., subjective reports of changes in color vision or adaptation to low light) but who do not meet the other (GVF) criteria for study entry

    3. Subjects who are girls or women of child-bearing potential must not be pregnant or lactating, must have negative serum pregnancy tests (≥25 mIU/mL sensitivity) at Screening (i.e., ≥19 days before Day -1, and on Day -1) and must have been practicing 2 adequate methods of birth control or complete abstinence for at least 2 months prior to study dosing. Adequate methods of birth control include (1) use of oral contraceptives (excluding low-dose oral formulation), implantable or injectable contraceptives, or an intrauterine device (IUD), with an additional barrier method (diaphragm with spermicidal gel OR condoms with spermicide); (2) a double-barrier method (diaphragm with spermicidal gel AND condoms with spermicide); (3) partner vasectomy; and (4) total abstinence. (Women are considered postmenopausal after 1 complete year of amenorrhea).

    4. Subjects who are boys or men must (1) agree to completely abstain from sexual intercourse, (2) have had a vasectomy, (3) use a barrier method (condoms) with spermicide and, if his partner is not using oral contraceptives, implantable or injectable contraceptives, or an IUD (as described in the criterion above), ensure that she is using a diaphragm with spermicidal gel during sexual intercourse, during the treatment phase of the study and for 2 months after finishing the last dose of study drug in Treatment Course 3.

    5. Subjects who provide informed consent and, if applicable, assent, for the study. The parent or guardian must sign an approved informed consent form for the study for subjects younger than the age of majority.
    Note that use of the term "subject" throughout this protocol may also include the parent/guardian of subjects younger than the age of majority, as appropriate.

    6. Subjects who are willing to comply with the protocol.
    E.4Principal exclusion criteria
    1. Subjects with any clinically important abnormal physical finding at Screening as determined by the Investigator.

    2. Subjects who have taken any prescription or investigational oral retinoid medication (e.g., Accutane/Roaccutane® or Soriatane/Neotigason®) excluding study medication QLT091001 within 6 months of Day 0 and subjects who did not tolerate their previous oral retinoid medication will be excluded regardless of the time of last exposure.

    3. Subjects with liver failure, cirrhosis, hepatitis, uncontrolled thyroid disease or chronic hyperlipidemia.

    4. Subjects with a hypersensitivity to retinoids or hypervitaminosis A syndrome

    5. Subjects with any of the following findings at Screening:
    - Blood pressure reading upon repeated measurement (i.e., 2 measurements) taken in a sitting or supine position of the following (by age group).
    5-9 years: 120/80 mmHg or higher
    10-13 years: 132/83 mmHg or higher
    14-17 years: 140/90 mmHg or higher
    18 years and older: 150/95 mmHg or higher

    5-9 years: <70 bpm or >130 bpm
    10-13 years: <45 bpm or >105 bpm
    14-17 years: <40 bpm or >100 bpm
    18 years and older: <40 bpm or >100 bpm
    - ALT, AST or fasting triglycerides >3 times the upper limit of the clinical laboratory value normal range (upon repeated measurement)
    - Thyroid stimulating hormone (TSH) outside the clinical laboratory value normal range (upon repeated measurement); other thyroid function tests to be evaluated by Investigator to exclude subjects with uncontrolled thyroid disease
    - Serum retinol clinical laboratory value above 98 μg/dL
    - Subjects who, in the Investigator’s opinion, have any severe acute or chronic medical condition, psychiatric condition, or laboratory abnormality that may increase the risk associated with study participation or administration of study treatment, or interfere with the interpretation of study results.

    6. Subjects with a marked QTc prolongation (>450 milliseconds [ms]) upon repeated demonstration (e.g., 2 of 3 assessments) at screening or baseline, which is considered to be clinically significant by the Investigator.

    7. Subjects with a history of risk factors for torsade de pointes (TdP) (e.g., heart failure, hypokalemia, history or family history of Long QT Syndrome), and Wolff-Parkinson-White (WPW) syndrome.

    8. Subjects who have taken any supplements containing ≥10,000 IU vitamin A within 60 days of Screening.

    9. Subjects who are actively participating in an experimental therapy study (other than RET IRD 01) or who have received another experimental therapy (in addition to QLT091001) within 60 days of Day 0.
