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.1.1.1Medical condition in easily understood language
    Hepatitis C
    E.1.1.2Therapeutic area Diseases [C] - Virus Diseases [C02]
    MedDRA Classification

    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective is to test if vitamin D supplementation improves the chances of standard treatment for HCV infection being effective. To test this we will measure if there is an improvement in the virologic response - ie the level of virus in the blood, 12 weeks after completion of treatment.
    E.2.2Secondary objectives of the trial
    • To determine the proportion of patients with rapid virological response (RVR is defined as negative viral load after only 4 weeks of therapy)
    • To determine the proportion of eligible patients undergoing standard therapy for HCV infection who consent to the study and the drop out rate from therapy of those who consent as compared to those who do not consent in order to establish if a larger multi centre trial to follow this one is feasible.
    • To determine the proportion of patients with sustained virologic response (SVR) at 24 weeks. (A SVR is defined as undetectable viral load 24 weeks after cessation of therapy).
    • To determine the impact on the immune system of supplementation with Vitamin D3 as measured by immune markers in the blood.
    • To determine the effect of supplementation with Vitamin D on adherence to standard HCV therapy.
    • To establish the cost effectiveness of the Vitamin D intervention modelled on treating all and treating those deficient on testing.

    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    • Have confirmed hepatitis C with positive PCR for genotype 1 or 3
    • Are planned to commence on standard eradication therapy for HCV
    • Aged 18 or over
    E.4Principal exclusion criteria
    • Hepatitis C genotype other than 1 or 3
    • Previous treatment with interferon/ribivarin
    • Contraindications to interferon / ribavirin therapy
    • eGFR <30 ml/min (by MDRD4 method)
    • Currently decompensated liver disease
    o Ascites, encephalopathy or variceal bleeding
    • History of renal calculi
    • Serum calcium <2.15 mmol/L or >2.60 mmol/L
    • History of sarcoidosis, metastatic malignancy
    • Hepatocellular carcinoma (current or previous)
    • Taking >400 units/day of vitamin D
    • HIV positive
    • Pregnancy
    • Breastfeeding
    • Of childbearing potential and not taking reliable contraception
    • Participation in another drug trial concurrently or within 30 days of screening for this one
    • Unable to provide written informed consent
    E.5 End points
    E.5.1Primary end point(s)
    To determine the proportion of patients with sustained virologic response (SVR) at 12 weeks post standard therapy on Vitamin D3 as compared to placebo.
    E.5.1.1Timepoint(s) of evaluation of this end point
    9 month visit
    E.5.2Secondary end point(s)
    1) To determine the proportion of patients with rapid virological response (RVR is defined as negative HCV PCR at 4 weeks of therapy) and who therefore receive response guided shortened therapy.
    2) To determine the proportion of eligible patients undergoing standard therapy for HCV infection who consent to the study and the drop out rate from therapy of those who consent as compared to those who do not consent.
    3) To determine the proportion of patients with sustained virologic response (SVR) at 24 weeks. (A SVR is defined as undetectable HCV RNA 24 weeks after cessation of therapy. If this is not available a surrogate of undetectable HCV RNA at greater than 12 weeks after cessation of therapy will be used).
    4). To determine the impact on the immune system of supplementation with Vitamin D3 as measured by immune markers.
    5)To determine the effect of supplementation with Vitamin D3 on adherence to standard HCV therapy.
    6) To establish the cost effectiveness of the Vitamin D intervention modelled on treating all and treating those deficient on testing.
