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   39806   clinical trials with a EudraCT protocol, of which   6534   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).
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial

    - compare the effect of ticagrelor vs placebo for reduction of; painful crises, ACS, duration of painful crises, days hospitalised for VOC, days hospitalised for acute SCD complications
    - compare the effect of ticagrelor vs placebo on the number of VOCs requiring hospitalisation or emergency department visits
    - compare the effect of ticagrelor vs placebo on the number of acute SCD complications
    - compare the effect of ticagrelor vs placebo on the number of sickle cell-related red blood cell (RBC) transfusions
    - describe the health-related quality of life (HRQL) and fatigue
    - describe intensity of pain during VOC
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Male or female paediatric patients aged ≥2 to <18 years and body weight of ≥12 kg (at Visit 1), diagnosed with HbSS or HbS/β0 as confirmed by high-performance liquid chromatography or haemoglobin electrophoresis.
    2. Have experienced at least 2 VOCs (painful crisis and/or ACS) as judged by the Investigator in the past 12 months prior to Visit 1. These VOCs need to be documented in the patient’s medical records or in other documents that can be reconciled.
    3. Prior to dosing on day of randomisation (Visit 2), a negative urine (dipstick) pregnancy test performed at Screening (Visit 1) and at Visit 2 must be available for female patients of childbearing potential.
    4. Females of childbearing potential (after menarche) must not become pregnant during study. Sexually active females must use a highly effective method of contraception which results in a low failure rate (ie, less than 1% per year). If use of effective contraception cannot be secured in sexually active females, the patient cannot be included in this study.
    E.4Principal exclusion criteria
    1. History of transient ischaemic attack (TIA) or cerebrovascular accident (ischaemic or haemorrhagic), severe head trauma, intracranial haemorrhage, intracranial neoplasm, arteriovenous malformation, aneurysm, or proliferative retinopathy.
    2. Findings on TCD: Current or previous values for time averaged mean of the maximum velocity (TAMMV) that are Conditional or Abnormal. Patients with Conditional TAMMV values or higher (≥153 cm/sec using TCD imaging technique which is corresponding to ≥170 cm/sec by the non-imaging technique). Both the middle cerebral artery and the internal carotid artery should be considered. Any other criteria that would locally be considered as TCD indications for chronic transfusion would also exclude the patient.
    3. Active pathological bleeding or increased risk of bleeding complications according to Investigator
    4. Haemoglobin <6 g/dL from test performed at Screening (Visit 1)
    5. Platelets <100 x (10)9/L from test performed at Screening (Visit 1)
    6. Undergoing treatment with chronic red blood cell transfusion therapy
    7. Chronic use of NSAIDs defined as continuous intake >3 days per week that cannot be discontinued
    8. Receiving chronic treatment with anticoagulants or antiplatelet drugs that cannot be discontinued
    9. Moderate or severe hepatic impairment defined as laboratory values of alanine aminotransferase (ALT) >2 × upper limits of normal (ULN), total bilirubin (TB) >2 × ULN (unless judged by the Investigator to be caused by haemolysis), albumin <35 g/L (3.5 g/dL) and International normalised ratio (INR) >1.4, or symptoms of liver disease (eg, ascites) from test performed at Screening (Visit 1).
    10. Renal failure requiring dialysis
    11. Patient considered to be at risk of bradycardic events (eg, known sick sinus syndrome or second or third degree atrioventricular block) unless already treated with a permanent pacemaker.
    12. Concomitant oral or intravenous therapy with strong or moderate cytochrome P450 3A4 (CYP3A4) inhibitors, CYP3A4 substrates with narrow therapeutic indices, or strong CYP3A4 inducers (see full list in Appendix G), which cannot be stopped at least 5 half-lives before randomisation.
    13. Active untreated malaria. Patients with suspected malaria at Screening (Visit 1) will be tested.
    14. Known hypersensitivity or contraindication to ticagrelor
    15. Patients who are currently pregnant or breastfeeding, or planning to become pregnant during the study or have given birth less than 3 months prior to Screening (Visit 1)
    16. Any condition which, in the opinion of the Investigator, would make it unsafe or unsuitable for the patient to participate in this study
    17. Concern for the inability of the patient or caregiver (defined as legally authorized representative) to comply with study procedures and/or follow-up
    18. Previous randomisation in the present study
    19. Participation in another clinical study with an IP or device during the last 30 days preceding enrolment.
    20. Involvement of member of patient’s family, or patient self, in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site).
