About this study

Official title: A Phase 1 Pharmacokinetic Study to Assess the Steady State Pharmacokinetic Profile and Short Term Safety of Maraviroc Dosed With Darunavir/Ritonavir All Once Daily, With and Without Nucleoside Analogues, in HIV-1 Infected Subjects

This is a phase I, open label, prospective, two phase pharmacokinetic study. Subjects currently attending for HIV care at St. Mary's Hospital, London will be eligible.

Read the detailed description

The study will describe the steady state pharmacokinetic parameters and short term safety of maraviroc/darunavir/ritonavir dosed at 150/800/100 mg once daily with and without tenofovir/emtricitabine 245/200 mg once daily in HIV-1 infected subjects.

Fifteen HIV-1 infected subjects will be recruited. Eligible subjects will currently be receiving antiretroviral therapy comprising:

  • tenofovir/emtricitabine 245/200 mg daily plus
  • darunavir/ritonavir 800/100 mg daily

On day 1, subjects will modify their current antiretroviral therapy to the following:

  • tenofovir/emtricitabine 245/200 mg daily plus
  • darunavir/ritonavir 800/100 mg daily plus
  • maraviroc 150 mg daily On day 10 subjects will undergo an intensive pharmacokinetic visit.

On day 11, subjects will modify their current antiretroviral therapy to the following:

  • darunavir/ritonavir 800/100 mg daily plus
  • maraviroc 150 mg daily (i.e. tenofovir/emtricitabine will be discontinued) On day 20 subjects will undergo an intensive pharmacokinetic visit. Following completion of this study phase, subjects will recommence their usual antiretroviral treatment regimen and attend for a study follow up visit.

What is being measured

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

  1. The Ratio of the Maximum Plasma Concentration of Maraviroc Between 20 and 10 Day

    On day 10 of the study the maximum concentractions of maraviroc will be measured . On day 20 of the study the maximum plasma concentractions maraviroc will be measured .

    Measured: 10 day, 20 days

Secondary outcomes (1)
  1. Number of Participants With Changes in Haematology and Biochemistry Laboratory Tests

    Haematology and biochemistry laboratory tests such as full blood count, elelectrolytes and lipids will be measured to assess for changes.

    Measured: 35 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Maraviroc, Truvada and Darunavir in people with HIV, run by Imperial College London 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 16 inclusion and 5 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 31 Oct 2019. 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?

Yes. Results are posted in the registry (first posted 31 Oct 2019). 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?

The Ratio of the Maximum Plasma Concentration of Maraviroc Between 20 and 10 Day (time frame: 10 day, 20 days). 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 NCT01348763, 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 31 Oct 2019; AzTrials last refreshed its copy on 7 Nov 2026.
