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   43860   clinical trials with a EudraCT protocol, of which   7283   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.2.2Secondary objectives of the trial
    To obtain exploratory evidence of pharmacodynamic (PD) and clinical efficacy endpoint changes from baseline in Aes-103-treated subjects compared with those receiving placebo with respect to the magnitude of effect, time course of effect, and relationship to plasma and red blood cell (RBC) concentrations of Aes-103.

Subjects are allowed concomitant usage of HU and other scheduled prescription drugs if the dosage is stable for the 2 months before screening and is at a dosage that does not exceed the product’s labeling. These scheduled prescription medications will be continued during the study. All other medications administered on an as-needed basis, including over-the-counter medications used according to the product labeling, will be permitted except for disulfiram, dextromethorphan, or dextrorphan. Medications for pain management will be allowed as needed.

    6. Have completed an outpatient screening visit consisting of medical history, physical examination, 12-lead ECG, vital signs, hematology and chemistry tests, urinalysis, urine drug screen, urine or serum pregnancy test (females), hemoglobin electrophoresis, hepatitis B and C screening, and HIV serology (Note: Subjects with abnormal screening values may be eligible if the results are not clinically significant or represent expected manifestations of SCD, as judged by the investigator in agreement with the sponsor or medical monitor.)
    7. Be able to understand and have provided written informed consent including signature on an informed consent form (ICF) approved by an institutional review board (IRB) or independent ethics committee (IEC)
    8. Have provided written authorization for use and disclosure of protected health information (PHI)
    9. Agree to abide by the study schedule and to return for the required assessments
    10. Be willing to abstain from foods high in 5-HMF (e.g., malt, barley, beer, balsamic vinegar, dried fruits, and caramel products) and limit consumption of coffee to 2 cups per day during the study
    11. Subjects with poor venous access who are unlikely to be able to provide repeated blood samples for pharmacokinetic analyses may be enrolled in the study if their venous access is sufficient to provide blood samples for safety assessments of clinical laboratory and hematology measures. (No more than 3 subjects per dose cohort with poor venous access may be enrolled.)
    E.4Principal exclusion criteria
    1. Have been hospitalized in the 14 days before enrollment, for any reason
    2. Have evidence of clinically significant cardiovascular, respiratory, renal, hepatic, pulmonary, gastrointestinal, hematological, neurological, psychiatric, or other disease that may interfere with the objectives of the study or the safety of the subject, as judged by the investigator in agreement with the sponsor or medical monitor, or have been hospitalized in the past 6 months as a result of these conditions (for SCD-related morbidity, a minimum of 14 days from the last hospitalization is required)
    3. Have a history of development of abnormal liver function test (LFT) values in association with administration of xenobiotic provided the causality relationship of the xenobiotic to the LFT abnormality is judged to be at least probably related.
    4. Be considered not suitable for participation in this study for any reason, as judged by the investigator
    5. Have taken any other investigational drug within 30 days before the screening visit
    6. Consumed more than 21 alcohol units per week in the last month or more than 3 units per day in the last week
    7. Have received disulfiram or 4-methoxypyrazole within 30 days before dosing (may affect PK results due to assay interference)
    8. Have received dextromethorphan or dextrorphan within 7 days before dosing
    9. Have taken herbal preparations in the 2 weeks before dosing
    10. Have positive result for urine drug test (cocaine, opiates [except prescribed], amphetamines, methamphetamines, benzodiazepines [except prescribed]) at screening visit (A positive test for THC will not be an exclusion)
