Darunavir Levels, Virological Efficacy, Proviral ADN and Resistances in Patients on Darunavir/Ritonavir Monotherapy (MonDar)

July 10, 2013 updated by: Luis F. Lopez-Cortes, Hospitales Universitarios Virgen del Rocío

Relation Between Darunavir Levels and Virological Efficacy, Integrated Proviral ADN and Resistance Mutations in HIV-infected Patients on Treatment With Darunavir/Ritonavir Monotherapy

To evaluate the relationship between plasma and intracellular darunavir (DRV) concentrations and virological efficacy in HIV-infected patients on DRV/rtv monotherapy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

To be enrolled, subjects had a plasma HIV-RNA <50 copies/mL for at least 6 months based, virologic failure while on a PI-containing regimen was allowed if the genotypic resistance tests showed no major resistance mutation associated to reduced susceptibility to DRV/rtv according to the International AIDS Society. Patients with transitory episodes of detectable plasma HIV-RNA viral load ("blip") preceded and followed by a plasma viral load <50 copies/mL without changes in antiretroviral treatment could also been included. The only exclusion criteria were pregnancy, hepatitis B coinfection and the concomitant use of drugs with potential major interactions with DRV/rtv pharmacokinetics.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

HIV-infected patients who started an antiretroviral regimen based on darunavir-ritonavir (800/100 mg) once daily monotherapy between June 2010 and September 2010

Description

Inclusion Criteria:

  • Older than 18 years, starting an antiretroviral regimen based on darunavir-ritonavir (800/100 mg) once daily monotherapy between June 2010 and September 2010
  • Plasma RNA-VIH < 50 copies/ml on stable antiretroviral treatment for ≥ 6 months
  • Absence of resistance mutations in the protease gene, based on treatment history and/or genotypic resistance testing. that would decrease darunavir susceptibility

Exclusion Criteria:

  • Pregnancy
  • Chronic B hepatitis
  • Genotypic resistance tests with evidence of resistance mutations in the protease gene that would decrease darunavir susceptibility
  • Concomitant use of drugs with potentially adverse interactions with darunavir-ritonavir pharmacokinetics, such as rifampin

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Virological efficacy
Time Frame: 48 and 96 weeks
To correlate the plasma and intracellular (cell-associated)) DRV levels with the virological efficacy analyzed by the time to loss of virological response (TLOVR) algorithm, considering VF as either: 1) two consecutive viral load >200 copies/mL, 2) a unique HIV-RNA >200 copies/mL if followed by lost to follow-up, or 3) the reintroduction of nucleos(t)ides because any reason.
48 and 96 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Impact of viral breakthrough on DNA-HIV reservoirs and immunologic activation
Time Frame: 48 and 96 weeks
Impact of blips and persistent viraemia on DNA-HIV reservoirs and immunologic activation
48 and 96 weeks

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
