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   43865   clinical trials with a EudraCT protocol, of which   7286   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 ).

    General information about the trial
    Main objective of the trial
    The main objective of this study was to evaluate the single-dose pharmacokinetic (PK) and bioequivalence of darunavir (DRV) 600 milligrams (mg) in the presence of cobicistat (COBI) 90 mg when administered as a fixed dose combination (FDC) tablet dispersed in water (DRV/COBI 600/90 mg) compared to the coadministration of the separate available formulations (DRV 100 milligram per millilitre [mg/mL] suspension at a dose of 600 mg and COBI 1*90 mg tablet), under fed conditions in healthy subjects.
    Protection of trial subjects
    This study was conducted in accordance with the ethical principles that have their origin in the Declaration of Helsinki and that are consistent with Good Clinical Practices and applicable regulatory requirements.

    The AUC (0-infinity) was the area under the plasma concentration-time curve from time zero to infinite time, calculated as the sum of AUC(last) and C(last) divided by lambda(z); wherein AUC(last) is area under the plasma concentration-time curve from time zero to last quantifiable time, C(last) is the last observed quantifiable concentration, and lambda(z) is elimination rate constant. PK data analysis set included all subjects who received at least 1 dose of study intervention and who had at least 1 plasma concentration data value/1 PK parameter value after study intervention administration.

    The AUC (0-infinity) was the area under the plasma concentration-time curve from time zero to infinite time, calculated as the sum of AUC(last) and C(last)/lambda(z); wherein AUC(last) is area under the plasma concentration-time curve from time zero to last quantifiable time, C(last) is the last observed quantifiable concentration, and lambda(z) is elimination rate constant. PK data analysis set included all subjects who received at least 1 dose of study intervention and who had at least 1 plasma concentration data value/1 PK parameter value after study intervention administration. Here, ‘Number of Subjects Analysed’ = subjects evaluable for this endpoint.

    		 Number of Subjects With Serious Adverse Events (SAEs)
    End point description
    An adverse event (AE) was any untoward medical occurrence in a subject who received study drug without regard to possibility of causal relationship. SAE was any untoward medical occurrence that at any dose resulted in death, was life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, was a suspected transmission of any infectious agent via a medicinal product. Safety analysis set included all subjects who received at least one dose of study intervention.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    22 Feb 2022
    The original protocol dated 08 December 2021 was amended once (22 February 2022) to correct an inconsistency between the Schedule of Activities and Section 8.1.3 (Electrocardiograms) of the protocol. The requirement for an electrocardiogram (ECG) assessment on Day -1 was removed from the Schedule of Activities as ECG was only required during screening. A more detailed instruction regarding the allowed intake of paracetamol/acetaminophen was added.

    Interruptions (globally)
    Were there any global interruptions to the trial? No
