What is being measured

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

  1. Time-Weighted Average Change From Baseline up to Day 11 (DAVG11) in Plasma HIV-1 RNA

    DAVG11 was defined as the time-weighted average between the first postbaseline value through the last available on-treatment (ie, the last dose date + 1) value up to Day 11 minus the baseline value in plasma HIV-1 RNA (log10 copies/mL). All HIV-1 RNA data up to Day 11 were used for this analysis. DAVG11 was calculated using the trapezoidal rule and the area-under-the-curve concept.

    Measured: Baseline up to Day 11

Secondary outcomes (16)
  1. Percentage of Participants Who Experienced Treatment-Emergent Adverse Events (AEs)

    Measured: First dose date up to last dose date plus 30 days (Maximum: 40 days)

  2. Percentage of Participants Who Experienced Graded Laboratory Abnormalities

    A treatment-emergent graded laboratory abnormality was defined as an increase of at least 1 toxicity grade from predose assessment and occurring after the predose visit and on or before the date of the last dose of study drug plus 30 days. If the predose assessment was missing, then any abnormality of at least Grade 1 associated with the study drug was considered a treatment-emergent graded laboratory abnormality. The most severe graded abnormality from all tests was counted for each participant.

    Measured: First dose date up to last dose date plus 30 days (Maximum: 40 days)

  3. Maximum Reduction From Baseline Through Day 17 in Plasma HIV-1 RNA

    Maximum reduction from baseline was defined as the minimum of change from baseline in plasma HIV-1 RNA (i.e. smallest change in HIV-RNA from baseline).

    Measured: Baseline to Day 17

  4. Viral Decay Slope in Plasma HIV-1 RNA

    Viral Decay Slope = (log10 [HIV-1 RNA on Day x] - log10 [HIV-1 RNA on Day 1]) / (x-1), where x is the collection day of the last available on treatment HIV-1 RNA collected up to Day 7.

    Measured: Baseline up to Day 11

  5. Percentage of Participants With HIV-1 RNA < 50 Copies/mL

    Measured: Day 17

  6. Pharmacokinetic (PK) Parameter: Cmax of Bictegravir Following Single-Dose and Multiple-Dose Administration

    Cmax is defined as the maximum concentration of drug.

    Measured: 0 (predose), 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 24 hours postdose at Day 1 for single dose and Day 10 for multiple dose

  7. PK Parameter: Tmax of Bictegravir Following Single-Dose and Multiple-Dose Administration

    Tmax is defined as the time (observed time point) of Cmax.

    Measured: 0 (predose), 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 24 hours postdose at Day 1 for single dose and Day 10 for multiple dose

  8. PK Parameter: AUC0-24 of Bictegravir Following Single-Dose Administration

    AUC0-24 is defined as the concentration of drug over time from time zero to time 24 hours.

    Measured: 0 (predose), 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 24 hours postdose at Day 1

  9. PK Parameter: AUClast of Bictegravir Following Single-Dose Administration

    AUClast is defined as the concentration of drug from time zero to the last observable concentration.

    Measured: 0 (predose), 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 24 hours postdose at Day 1

  10. PK Parameter: AUCtau of Bictegravir Following Multiple-Dose Administration

    AUCtau is defined as concentration of drug over time (the area under the concentration verses time curve over the dosing interval).

    Measured: 0 (predose), 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 24 hours postdose at Day 10

  11. PK Parameter: t1/2 of Bictegravir Following Multiple-Dose Administration

    t1/2 is defined as the estimate of the terminal elimination half-life of the drug.

    Measured: 0 (predose), 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 24 hours postdose at Day 10

  12. PK Parameter: Ctau of Bictegravir Following Multiple-Dose Administration

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

    Measured: 0 (predose), 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 24 hours postdose at Day 10

  13. PK Parameter: CLss/F of Bictegravir Following Multiple-Dose Administration

    CLss/F is defined as the apparent oral clearance following multiple-dose administration of the drug.

    Measured: 0 (predose), 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 24 hours postdose at Day 10

  14. PK Parameter: AR_AUC of Bictegravir Following Multiple-Dose Administration

    Accumulation ratio of AUC (AR_AUC) = AUCtau on Day 10 / AUC0-24 on Day 1. Percentage of accumulation ratio has been reported.

    Measured: 0 (predose), 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 24 hours postdose at Day 1 and 10

  15. PK Parameter: AR_Cmax of Bictegravir Following Multiple-Dose Administration

    Accumulation ratio of Cmax (AR_Cmax) = Cmax on Day 10 / Cmax on Day 1. Percentage of accumulation ratio has been reported.

    Measured: 0 (predose), 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 24 hours postdose at Day 1 and 10

  16. PK/Pharmacodynamic (PD) Analysis: Pearson Correlation Between AUCtau of Bictegravir and DAVG11 in Plasma HIV-1 RNA

    AUCtau is defined as concentration of drug over time (the area under the concentration verses time curve over the dosing interval). DAVG11 was defined as the time-weighted average between the first postbaseline value through the last available on-treatment (ie, the last dose date + 1) value up to Day 11 minus the baseline value in plasma HIV-1 RNA (log10 copies/mL).

    Measured: 0 (predose), 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 24 hours postdose at Day 10

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Bictegravir in people with HIV-1 Infection, run by Gilead Sciences at 16 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 3 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 9 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 16 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. Some participants in this study may receive a placebo. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 8 Oct 2020). 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?

Time-Weighted Average Change From Baseline up to Day 11 (DAVG11) in Plasma HIV-1 RNA (time frame: Baseline up to Day 11). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 9 Nov 2020; AzTrials last refreshed its copy on 8 Nov 2026.
