Study groups in NCT02397694
Study groupRoleWhat they receive
BIC + F/TAFExperimentalParticipants will receive BIC + F/TAF FDC + DTG placebo for 48 weeks. * Following Week 48, participants will continue to take their blinded treatment and attend visits every 12 weeks until treatment assignments have been unblinded. Participants will return for an unblinding visit and be given the option to participate in an open-label rollover extension and receive bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) until it becomes commercially available, or until Gilead Sciences elects to terminate the development of BIC/F/TAF.
Receives: Drug: BIC; Drug: F/TAF; Drug: DTG Placebo; Drug: B/F/TAF
DTG + F/TAFActive comparatorParticipants will receive DTG + F/TAF FDC + BIC placebo for 48 weeks. * Following Week 48, participants will continue to take their blinded treatment and attend visits every 12 weeks until treatment assignments have been unblinded. Participants will return for an unblinding visit and be given the option to participate in an open-label rollover extension and receive B/F/TAF until it becomes commercially available, or until Gilead Sciences elects to terminate the development of BIC/F/TAF.
Receives: Drug: F/TAF; Drug: DTG; Drug: BIC Placebo; Drug: B/F/TAF
Open Label Extension PhaseExperimentalAfter Week 48 participants continued to take their randomized study drug and attended visits every 12 weeks until treatment assignments were unblinded, at which point all participants returned for an unblinding visit and were given the option to participate in an open-label rollover extension to receive an FDC containing B/F/TAF.
Receives: Drug: B/F/TAF

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 as Determined by the FDA-defined Snapshot Algorithm.

    The percentage of participants achieving HIV-1 RNA < 50 copies/mL at Week 24 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 24

Secondary outcomes (15)

    Measured: Week 12

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

  12. PK Parameter: Tmax for BIC, FTC, TAF, and TFV at Steady-State

    Tmax was defined as the time to Cmax.

    Measured: 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 24 hours postdose at Week 4 or 8

  13. PK Parameter:Ctau for BIC, FTC and TFV

    Ctau was defined as the observed drug concentration at the end of the dosing interval.

    Measured: 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 24 hours postdose at Week 4 or 8

  14. PK Parameter: AUCtau for BIC, FTC, TAF, and TFV

    AUCtau is defined as the area under the concentration-time curve of the drug over time.

    Measured: 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 24 hours postdose at Week 4 or 8

  15. PK Parameter: t1/2 of BIC, FTC, TAF, and TFV

    t1/2 was defined as the terminal elimination half-life of the drug

    Measured: 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 24 hours postdose at Week 4 or 8

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing BIC, F/TAF and DTG in people with HIV-1 Infection, run by Gilead Sciences at 21 sites in United States.

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 5 inclusion and 7 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 7 Apr 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 21 sites in United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 27 Mar 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 as Determined by the FDA-defined Snapshot Algorithm. (time frame: Week 24). 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 NCT02397694, which also lists 2 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 7 Apr 2020.
