Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   42567   clinical trials with a EudraCT protocol, of which   7008   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    A.3Full title of the trial
    A Phase 3b, Multicenter, Open-Label Study to Evaluate Switching from an Elvitegravir/Cobicistat/Emtricitabine/Tenofovir Alafenamide Fixed-Dose Combination Regimen or a Tenofovir Disoproxil Fumarate Containing Regimen to Fixed-Dose Combination of Bictegravir/Emtricitabine/Tenofovir Alafenamide in Elderly, Virologically-Suppressed, HIV-1 Infected Subjects Aged ≥ 65 Years
    A.3.1Title of the trial for lay people, in easily understood, i.e. non-technical, language
    The study will test an experimental drug called B/F/TAF (bictegravir/emtricitabine/tenofovir alafenamide) fixed-dose combination (FDC) for the treatment of HIV-1 infection. The purpose of this study is to evaluate the effectiveness of switching to B/F/TAF FDC in HIV-1 infected adults aged ≥ 65 years who are virologically suppressed (HIV-1 RNA test <50 copies/mL) currently on elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide FDC or tenofovir disoproxil fumarate containing regimens.

    E.3Principal inclusion criteria
    Subjects must meet all of the following inclusion criteria to be eligible for participation in this study.
    1) The ability to understand and sign a written informed consent form, which must be obtained prior to initiation of study procedures
    2) Age ≥ 65 years
    3) Currently receiving an ARV regimen of E/C/F/TAF FDC (or FTC/TDF + 3rd agent if currently or previously participated in GS-US-292-1826) for ≥ 3 months
    4) Documented plasma HIV-1 RNA < 50 copies/mL during treatment with E/C/F/TAF (or FTC/TDF + 3rd agent if currently or previously participated in GS-US-292-1826) for the last 2 visits preceding the Screening Visit (or undetectable HIV-1 RNA level according to the local assay being used if the limit of detection is ≥ 50 copies/mL)
    a) Unconfirmed virologic elevations of ≥ 50 copies/mL but < 400 copies/mL (transient detectable viremia, or “blip”) in the past are acceptable.
    b) If the lower limit of detection of the local HIV-1 RNA assay is < 50 copies/mL (eg, < 20 copies/mL), the plasma HIV-1 RNA level cannot exceed 50 copies/mL on two consecutive HIV-1 RNA tests after < 50 copies/mL has been achieved.
    5) Plasma HIV-1 RNA levels < 50 copies/mL at Screening Visit
    6) Have no documented or suspected resistance to FTC, TFV, or BIC including, but not limited, to the reverse transcriptase resistance mutations K65R and M184V/I
    7) Normal ECG (or if abnormal, determined by the Investigator to be not clinically significant)
    8) Adequate renal function: eGFR ≥ 30 mL/min according to the Cockcroft-Gault formula for creatinine clearance
    9) Male subjects who are fertile and engage in heterosexual intercourse with women who are of child-bearing potential must agree to use protocol specified method(s) of contraception
    10) Male subjects must agree to refrain from sperm donation from first study drug dose until after the end of relevant systemic exposure
    11) Life expectancy > 1 year

    E.4Principal exclusion criteria
    Subjects who meet any of the following exclusion criteria are not to be enrolled in this study.
    1) An opportunistic illness indicative of stage 3 HIV diagnosed within the 30 days prior to screening
    2) Subjects experiencing decompensated cirrhosis (eg, ascites, encephalopathy, or variceal bleeding)
    3) Have been treated with immunosuppressant therapies or chemotherapeutic agents within 3 months of study screening, or expected to receive these agents or systemic steroids (e.g. prednisone doses > 10 mg daily or equivalent) during the study (eg, corticosteroids, immunoglobulins, and other immune- or cytokine-based therapies)
    4) Current alcohol or substance use judged by the Investigator to potentially interfere with subject study compliance

    7) Participation in any other clinical trial, including observational studies, without prior approval from the Medical Monitor
    8) Any other clinical condition or prior therapy that, in the opinion of the Investigator, would make the subject unsuitable for the study or unable to comply with the dosing requirements
    9) Known hypersensitivity to B/F/TAF FDC tablets, their metabolites, or formulation excipient
