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   44334   clinical trials with a EudraCT protocol, of which   7366   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.

    For each drug (Truvada and Descovy) we have the following objectives:
    Part 1:
    1. To determine the time from first dose of drug to ex vivo protection from HIV-1 infection
    2. To determine the time to cessation of ex vivo protection from HIV-1 following stopping ART after attaining steady state.
    3. To determine the impact of TRUVADA® and DESCOVY® on the genital microbiome in men and women
    4. To determine the relationship between protection from ex vivo infection in tissue and Peripheral Blood Mononuclear Cells (PBMC)
    5. To investigate PrEP acceptability and feedback on the trial implementation


    Part 2:
    1. To determine the level of drug required in the plasma, saliva, vagina and rectum for ex vivo protection from HIV-1
    2. To determine the optimal time from PrEP dosing to HIV exposure
    3. To determine the contribution of post exposure dosing in on-demand PrEP

This includes intrauterine device, , anatomical sterility in self or partner, oral hormonal methods, and implant contraceptives. In case of anatomical sterility in a partner, for example vasectomy, it will be considered a highly effective birth control method provided that the partner is the sole sexual partner of the WOCBP trial participant and that the vasectomised partner has received medical assessment of the surgical success
