  6. Percentage of Participants Experiencing Adverse Events or Graded Laboratory Abnormalities

    Adverse events (AEs) and graded laboratory abnormalities occurring during the E/C/F/TAF treatment period were summarized across the participant population. A participant was counted once if they had a qualifying event.

    Measured: Baseline up to Week 240 plus 30 days

  7. Percentage of Participants Achieving HIV-1 RNA < 50 Copies/mL at Weeks 24, 48, 96, and 144

    The percentage of participants achieving HIV-1 RNA < 50 Copies/mL at Weeks 24, 48, 96, and 144 was analyzed using the snapshot algorithm, which defines a patient'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: Weeks 24, 48, 96, and 144

  8. Pharmacokinetic (PK) Parameter: Cmax of TAF

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing E/C/F/TAF in people with HIV and HIV Infections, run by Gilead Sciences at 70 sites in 9 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 24 inclusion and 14 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 2 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 70 sites in United States, Thailand, United Kingdom, Australia, Spain and 4 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 18 Feb 2016). 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?

Change From Baseline in the Estimated Glomerular Filtration Rate Calculated by the Cockcroft-Gault Formula (eGFR_CG) at Week 24 (time frame: Baseline; Week 24). The study lists 3 primary outcomes in all. 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 NCT01818596, 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 2 Mar 2020.
