Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Currently receiving a once daily antiretroviral regimen consisting of ritonavir or cobicistat boosted ATV or DRV plus either FTC/TDF or ABC/3TC for ≥ 6 months preceding the screening visit
  • Adequate renal function:
  • Estimated glomerular filtration rate ≥ 50 mL/min (≥ 0.83 mL/sec) according to the Cockcroft-Gault formula
  • Life expectancy ≥ 1 year
  • Currently on a stable regimen for ≥ 6 months preceding the screening visit with documented plasma HIV-1 RNA < 50 copies/mL for ≥ 6 months 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). Prior changes in antiretroviral regimen are only allowed due to tolerability issues or for regimen simplification. Unconfirmed virologic elevations of ≥ 50 copies/mL (transient detectable viremia, or "blip") prior to screening are acceptable. (If the lower limit of detection of the local HIV-1 RNA assay is < 50 copies/mL [e.g., < 20 copies/mL], the plasma HIV-1 RNA level cannot exceed 50 copies/mL on two consecutive HIV-1 RNA tests)
  • Have no documented or suspected resistance to FTC, tenofovir, ABC or 3TC, including but not limited to the reverse transcriptase resistance mutations K65R and M184V/I
  • No previous use of any approved or experimental integrase strand transfer inhibitor (INSTI)

Who cannot join

  • An opportunistic illness indicative of stage 3 HIV diagnosed within the 30 days prior to screening
  • Individuals experiencing decompensated cirrhosis (eg, ascites, encephalopathy, or variceal bleeding)
  • Have been treated with immunosuppressant therapies or chemotherapeutic agents within 3 months of study screening, or expected to receive these agents or systemic steroids during the study (eg, corticosteroids, immunoglobulins, and other immune- or cytokine based therapies)
  • Current alcohol or substance use judged by the Investigator to potentially interfere with subject study compliance
  • A history of or ongoing malignancy (including untreated carcinoma in-situ) other than cutaneous Kaposi's sarcoma (KS), basal cell carcinoma, or resected, non-invasive cutaneous squamous carcinoma. Individuals with biopsy-confirmed cutaneous KS are eligible, but must not have received any systemic therapy for KS within 30 days of Day 1 and are not anticipated to require systemic therapy during the study
  • Active, serious infections (other than HIV 1 infection) requiring parenteral antibiotic or antifungal therapy within 30 days prior to Day 1
Show all 17Show fewer
  • Participation in any other clinical trial, including observational studies, without prior approval from the sponsor is prohibited while participating in this trial
  • Any other clinical condition or prior therapy that, in the opinion of the Investigator, would make the individual unsuitable for the study or unable to comply with the dosing requirements
  • Any known allergies to the excipients of B/F/TAF FDC or ATV, RTV, DRV, COBI, FTC/TDF or ABC/3TC
  • Females who are pregnant (as confirmed by positive serum pregnancy test)
  • Females who are breastfeeding
  • Acute hepatitis in the 30 days prior to study entry
  • Chronic hepatitis B infection in individuals not on a TDF containing regimen, as determined by either:
  • Positive hepatitis B virus (HBV) surface antigen and negative HBV surface antibody, regardless of HBV core antibody status, at the screening visit
  • Positive HBV core antibody and negative HBV surface antibody, regardless of HBV surface antigen status, at the screening visit
  • Active tuberculosis infection
  • Note: Other protocol defined Inclusion/Exclusion criteria may apply.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants With HIV-1 RNA ≥ 50 Copies/mL at Week 48 as Determined by the FDA-Defined Snapshot Algorithm

    The percentage of participants with HIV-1 RNA ≥ 50 copies/mL at Week 48 was analyzed using the snapshot algorithm, which defines a participant's virologic response status using only the viral load at the predefined time point within an allowed window of time, along with study drug discontinuation status.

    Measured: Week 48

Secondary outcomes (2)
  1. Percentage of Participants With HIV-1 RNA < 50 Copies/mL at Week 48 as Determined by the FDA-Defined Snapshot Algorithm

    The percentage of participants with HIV-1 RNA < 50 copies/mL at Week 48 was analyzed using the snapshot algorithm, which defines a participant's virologic response status using only the viral load at the predefined time point within an allowed window of time, along with study drug discontinuation status.

    Measured: Week 48

  2. Change From Baseline in CD4 Cell Count at Week 48

    Measured: Baseline to Week 48

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing RTV, ATV and DRV in people with HIV-1 Infection, run by Gilead Sciences at 119 sites in 11 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Dec 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 119 sites in United States, United Kingdom, Germany, France, Canada and 6 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 6 Jun 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Participants With HIV-1 RNA ≥ 50 Copies/mL at Week 48 as Determined by the FDA-Defined Snapshot Algorithm (time frame: Week 48). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02603107, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Dec 2020.
