About this study
Official title: Elvitegravir/Cobicistat/Tenofovir DF/Emtricitabine With Darunavir in Treatment-experienced Patients: Quality Control Monitoring of a Treatment Simplification Strategy
The study aims to assess the safety and efficacy of darunavir 800mg plus the co-formulated elvitegravir/cobicistat/tenofovir disoproxil fumarate (DF)/emtricitabine (Stribild) tablet as a simplification strategy for the treatment of HIV infection in HIV-infected subjects who have had previous antiretroviral treatment experience with multiple-drug regimens.
We hypothesize that elvitegravir/cobicistat/tenofovir DF/emtricitabine with darunavir will offer a safe and efficacious treatment simplification strategy for HIV positive patients currently receiving multiple-drug regimens to control their HIV infection.
Read the detailed description
Eligible, consenting subjects will be assessed at baseline and weeks 2, 12, 24, 36, and 48. Study medications will be dispensed at all visits except week 2, and all participants will commence taking open-label darunavir 800mg in conjunction with the co-formulated tenofovir DF/emtricitabine/cobicistat/elvitegravir (Stribild) tablet, both taken together once daily with food, following study procedures at baseline.
Assessments at the study visits will include:
- Complete physical exam including height and weight at baseline; symptom-directed physical exam and weight at other visits
- Adverse clinical events including serious adverse events (hospitalizations etc.) and medication changes at every visit.
- HIV RNA every 4 weeks.
- CD4 and CD8 absolute counts and % at all visits except week 2.
- Platelet count, aspartate amino transferase (AST), creatinine, estimated glomerular filtration rate (eGFR), phosphorus, urinalysis, and urine albumin to creatinine ratio (UACR) at each visit.
- Fasting lipids (total, HDL, and LDL cholesterol and triglycerides), apolipoprotein B, high-sensitivity C- reactive protein (hsCRP) at baseline, week 24, and week 48.
- Pregnancy test for women of child-bearing potential (as defined above) at every visit except week 2. In addition, pregnancy tests will be performed monthly for women of child-bearing potential; between study visits these may be done at home.
- A plasma sample (3 mL) will be collected and stored once at baseline for all subjects, and used for measurement of darunavir trough (pre-dose) concentration in subjects receiving darunavir in their pre-study regimen.
- All subjects will take their study medication under observation in the clinic on Day 14, and plasma samples (3mL) for pharmacokinetic testing will be drawn immediately pre-dose and at 1, 2, 3, 4, 5, 6, and 8 hours post-dose. Subjects will return the following day before taking their Day 15 dose for a 24-hour post-dose sample.
- Peripheral blood mononuclear cells (PBMCs) will be collected and stored at baseline for possible future study-related testing.
- The following questionnaires will be completed by participants prior to other study procedures at baseline and at weeks 24 and 48: MOS-HIV quality of life questionnaire; HIVTSQ; ACTG treatment adherence questionnaire; and the medication adherence self-report inventory (MASRI).

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Treatment simplification in people with HIV Infection, run by University of British Columbia at 1 site in Canada.
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 4 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 6 Nov 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Plasma HIV RNA (time frame: 12 weeks). 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 NCT02199613, which also lists 1 linked publication.
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 6 Nov 2017; AzTrials last refreshed its copy on 8 Nov 2026.
