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   43845   clinical trials with a EudraCT protocol, of which   7282   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.

    General information about the trial
    Main objective of the trial
    Part 1 - Dose-Ranging. Evaluated the (1) safety and tolerability and (2) efficacy (antiretroviral activity) of 4 doses of doravirine (MK-1439) compared with efavirenz, each given in combination with TRUVADA® (emtricitabine 200 mg + tenofovir disoproxil fumarate 300 mg) for at least 24 weeks. A single dose of doravirine was selected for further study after all participants completed the Week 24 visit. Part 2 - Selected Dose. Evaluated the safety of the selected dose of doravirine compared with efavirenz through Week 96, particularly with regard to early onset (by Week 8 and 24) of central nervous system adverse events (CNS events). The hypothesis tested in this study was that MK-1439 at the final dose selected is superior to efavirenz, each given in combination with TRUVADA, as measured by the proportion of participants with CNS events by Week 8. If superiority was established at Week 8, the same hypothesis was tested for Week 24.
    Protection of trial subjects
    This study was conducted in conformance with Good Clinical Practice standards and applicable country and/or local statutes and regulations regarding ethical committee review, informed consent, and the protection of human subjects participating in biomedical research.

    End point description
    A primary endpoint in Part I was the percentage of participants receiving doravirine (MK-1439) at all doses (25 mg, 50 mg, 100 mg, or 200 mg), compared with participants receiving efavirenz 600 mg, who had at least 1 AE over 24 weeks of treatment. The relative number (n/N [%]) of participants in any treatment group with at least 1 AE was primarily assessed for Weeks 0-24.

    A secondary endpoint in Part I was the percentage of participants receiving doravirine (MK-1439) at all doses (25 mg, 50 mg, 100 mg, and 200 mg), compared with participants receiving efavirenz 600 mg, who had a virologic response (plasma HIV RNA < 200 copies/mL) over 24 weeks of treatment. The relative number (n/N [%]) of participants in either treatment group with this virologic response was assessed for Weeks 0-24.
