June 29, 2018 updated by: Jose L. Casado, Asociacion para el Estudio de las Enfermedades Infecciosas

A Retrospective Cohort Study of the Efficacy and Evolution of Comorbidities With the Combination of Raltegravir and Boosted Darunavir in Suppressed HIV-infected Patients With Intolerance or Toxicity to Nucleoside Analogues

Retrospective cohort of virologically suppressed HIV-infected patients who received the combination of Raltegravir plus Darunavir boosted with cobicistat or ritonavir, as dual therapy, because or toxicity or intolerance to nucleoside analogues

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

This is a retrospective cohort study including those HIV-infected patients who received the combination of raltegravir plus darunavir boosted with cobicistat or ritonavir as dual therapy, due to the existence of toxicity or intolerance to nucleoside analogues, to evaluate:

  • efficacy, measured as percentage of patients free of virological failure after 48 and 96 weeks (ITT-e, snapchot analysis) and improvement in CD4+ count
  • tolerance (rate of discontinuation and cause, and frequency of adverse events)
  • evolution of different comorbidities (renal, bone, cardiovascular events)

Patients will included if they have received at least 1 dose of the dual therapy

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

HIV infected patients with virological suppression but toxicity or intolerance to analogues who switched to the combination of Raltegravir plus boosted Darunavir

Description

Inclusion Criteria:

  • HIV infection
  • Older than 18 years
  • To have received the combination of raltegravir plus boosted darunavir in patients with virological suppression (more than 6 months) after toxicity or intolerance to nucleoside analogues

Exclusion Criteria:

  • Virological failure in the last 6 months previous to dual therapy
  • Presence or suspicion of resistance to Darunavir (major mutations according to Meyer et al) or to Raltegravir (major mutations according to IAS list)
  • Active hepatitis B

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
Percentage of patients who maintained virological suppression on treatment at 48 weeks after using this dual therapy
Time Frame: 48 weeks
The number of patients who remained with virological suppression during the study at 48 weeks (ITT-exposed, snapchot analysis)
48 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
Change in renal parameters at 48 weeks,for patients using dual therapy
Time Frame: 48 weeks
Evaluation of renal parameters in patients changing to this dual therapy, considering the previous use of TDF or not.
48 weeks
Change in bone parameters (bone mineral density by Dual X-ray absorptiometry) during the study
Time Frame: 48 weeks
Quantitative changes in bone mineral density (BMD) according to previous use of TDF and renal parameters
48 weeks
Change in cardiovascular risk (by using AHA score) for patients using dual therapy
Time Frame: 48 weeks
Changes in lipid parameters will be assessed
48 weeks
Changes in inflammatory markers during the study, measured by the CD4/CD8 ratio
Time Frame: 48 weeks
Those patients who received this dual therapy will be evaluated to determine changes in inflammatory biomarkers such as CD4/CD8 ratio
48 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 (Actual)

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.
December 15, 2017

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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
