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   44339   clinical trials with a EudraCT protocol, of which   7369   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 objective (Period II, Week 8 to Week 16) is to demonstrate the additional antihypertensive efficacy for SeDBP gained by adding HCTZ 12.5 or 25 mg to the treatment regimen in subjects with moderate to severe HTN not adequately controlled on OM/AML 40/10 mg alone, at Week 16 (after 8 weeks of double-blind treatment) using conventional BP measurement.
    E.2.2Secondary objectives of the trial
    Period II: 1. Evaluate antihypertensive efficacy for SeDBP of triple combination OM/AML/HCTZ 40/10/12.5 & 40/10/25 mg vs OM/AML 40/10 mg at Wk(week)12. 2. Evaluate antihypertensive efficacy for SeSBP of OM/AML/HCTZ 40/10/12.5 & 40/10/25mg vs OM/AML 40/10mg at Wk12&16. 3. Evaluate antihypertensive efficacy from baseline to Wk16 (see protocol p36). 4. Evaluate % no. subjects achieving BP goal (SeBP, see protocol p36) and % no. subjects achieving SeBP thresholds (see protocol p.36) at Wk12&16. 5. Evaluate safety & tolerability of triple combination therapy at Wk8-16. Period III&IV: 1. Evaluate antihypertensive efficacy of up titration of dose to 40/10/25mg in subjects not reaching BP goal on dose 40/10/12.5mg based on changes from Wk24-32 (see protocol p36). 2. Evaluate % no. subjects achieving BP goal & BP thresholds (defined point 4 above) at Wk32. 3. Evaluate safety & tolerability of triple combination therapy during Wk16-32.
    E.2.3Trial contains a sub-study No

    OR:
    For subjects on monotherapy: mean trough SeBP of ≥ 150/95 mmHg (SeSBP of ≥ 150 mmHg and SeDBP ≥ 95 mmHg) at Screening and mean 24-hour DBP of at least 80 mmHg and with at least 30% of daytime DBP readings over 85 mmHg.

    OR:
    For subjects on any other combination of antihypertensive medications that includes neither HCTZ, OM nor AML: mean trough SeSBP ≥ 160 mmHg, mean trough SeDBP ≥ 100mmHg, at the end of the taper-off period and a mean 24-hour DBP of at least 85 mmHg, assessed by 24-hour ABPM, with at least 30% of daytime DBP readings above 90 mmHg.
    3. Subject freely signs ICF after the nature of the study and the disclosure of his/her data has been explained.
    4. Female subjects of childbearing potential must be using adequate contraception (female of childbearing potential is defined as one who has not been postmenopausal for at least one year, or has not been surgically sterilised, or has not had a hysterectomy at least three months prior to the start of this study [Visit 1]). Females taking oral contraceptives should have been on therapy for at least three months. Adequate contraceptives include hormonal intra-uterine devices, hormonal contraceptives (oral, depot, patch or injectable), and double barrier methods such as condoms or diaphragms with spermicidal gel or foam. If a female becomes pregnant during the study, she has to be withdrawn immediately.
    E.4Principal exclusion criteria
    1. Female subjects of childbearing potential who are pregnant or lactating.
    2. Subjects with serious disorders which may limit the ability to evaluate the efficacy or safety of the investigational products, including cerebrovascular, cardiovascular, renal, respiratory, hepatic, gastrointestinal, endocrine or metabolic, haematological or oncological, neurological, and psychiatric diseases. The same applies for immunocompromised and/or neutropenic subjects.
    3. Subjects having a history of the following within the last six months: MI, unstable angina pectoris, percutaneous coronary intervention, heart failure, hypertensive encephalopathy, cerebrovascular accident (stroke), or transient ischaemic attack.
    4. Subjects with clinically significant abnormal laboratory values at Screening, including subjects with one or more of the following:
    • Aspartate aminotransferase (AST) > 3 times upper limit of normal (ULN)
    • ALT > 3 times ULN
    • Gamma-glutamyltransferase (GGT) > 3 times ULN
    • Potassium above ULN (unless high value is due to haemolytic blood sample)
    5. Subjects with secondary HTN of any aetiology such as renal disease, phaechromocytoma, or Cushing’s syndrome.
    6. Subjects with contraindication to OM, AML, HCTZ, or any of the excipients.
    7. Subjects with a mean SeSBP > 200 mmHg or SeDBP > 115 mmHg or bradycardia (heart rate < 50 beats/min at rest documented by mean radial PR or ECG at Screening (Visit 1) or immediately before taking Period I study medication (Visit 2).
    8. Subjects already taking four or more antihypertensive medications.
    9. Subjects with ECG evidence of 2nd or 3rd degree atrio-ventricular (AV) block, atrial fibrillation, or other cardiac arrhythmia (requiring treatment).
    10. Subjects with severe heart failure (New York Heart Association stage III IV), clinically significant aortic or mitral valve stenosis, uncorrected coarctation of the aorta, obstruction of cardiac outflow (obstructive, hypertrophic cardiomyopathy) or symptomatic coronary disease.

    18. Subjects with a current history of alcohol and/or drug abuse.
    19. Subjects who have received any investigational drug within 30 days prior to Screening.
    20. Subjects who are unwilling or unable to provide informed consent or to participate satisfactorily for the entire study.
    21. Signs or symptoms which could exacerbate the occurrence of hypotension such as volume and salt depletion.
    22. Uncontrolled Type 1 or Type 2 diabetes defined as an HbA1c > 9.0%. Diabetics must have documentation of an HbA1c level within 6 months of the Screening Visit, or must have their HbA1c level documented prior to randomisation. Note: subjects with Type 1 or Type 2 diabetes controlled with insulin, diet or oral hypoglycaemic agents on a stable dose for at least 30 days may be included.
    23. Subjects with malignancy during the past 2 years excluding squamous cell or basal cell carcinoma of the skin.
    24. A subject with any medical condition, which in the judgment of the Investigator would jeopardise the evaluation of efficacy or safety and/or constitute a significant safety risk to the subject.
