About this study
The purpose of the study is to look at the levels of three HIV medications: tenofovir, emtricitabine, and rilpivirine in blood after the drug intake has been stopped in order to understand how long these drugs persist in the blood. The study will specifically look at blood levels of these three drugs (taken as a 3-in-1 tablet) after taking them every day for 14 days.
The duration of the subjects involvement in the study will be up to 23 days plus a screening visit which will take place up to 4 weeks prior to the start of the study, and a follow up visit which takes place 16-22 days after the last dose of study medication.
This study is not randomised which means that all participants will receive all study medications in the same order. The participant and the study doctor will know which study medications you are taking at all times during the study.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Eviplera® in people with HIV, run by St Stephens Aids Trust at 1 site in United Kingdom.
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 9 inclusion and 11 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 25 Jul 2013. 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 United Kingdom. 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 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?
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 concentrations of tenofovir, emtricitabine and rilpivirine, and intracellular concentrations of tenofovir di-phosphate and emtricitabine tri-phosphate (time frame: 23 days). 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 25 Jul 2013.
