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   43857   clinical trials with a EudraCT protocol, of which   7284   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
    The Primary efficaccy objective of this study is to determine if immunization with ATV is effective in reducing mean daytime DBP measured by ambulatory blood pressure monitoring (ABPM) in subjects with mild to moderate hypertension.
    E.2.2Secondary objectives of the trial
    The secondary objectives of this study are to examine the effect of immunization with ATV on:
    • Mean 24-hour SBP measured by ABPM
    • Mean 24-hour DBP measured by ABPM
    • Mean sitting and standing morning DBP and SBP measured by sphygmomanometry
    • Mean morning DBP and SBP, daytime SBP, and night-time DBP and SBP measured by ABPM
    • Percent of subjects meeting DBP and SBP treatment target goals as measured by sphygmomanometry

    Safety Objectives
    To assess the local and systemic safety and tolerability of immunization with ATV in the study population.

    Immunological Objective
    To evaluate the immunogenicity of the ATV as measured by anti-angiotensin IgG titres.

    Additional Measures of Interest
    Aldosterone (serum) and active renin (plasma) concentrations, immune complex formation as well as other pharmacologic and/or immunologic measures.

    Systolic BP (SBP) Diastolic BP (DBP)
    Grade 1 140 – 159 mmHg 90 – 99 mmHg

Women who are surgically sterile or are documented to have been post-menopausal for at least 2 years will be considered for study participation. Post-menopausal female subjects who are <60 years of age and who are not surgically sterile will be required to use a double-barrier method of birth control during the Treatment Period and Follow-up Period until their anti-angiotensin IgG titres approximates the subject’s baseline levels.
    3. Subjects with an average sitting SBP of >180 mmHg or DBP of >110 mmHg.
    4. Subjects with a BP difference between left and right arm on screening greater than 20 mmHg for SBP and 10 mmHg for DBP which is present on 3 consecutive readings.
    5. Subjects with left ventricular (LV) systolic dysfunction as evidenced by a known LV ejection fraction <40% or symptomatic congestive heart failure (CHF) requiring treatment.
