Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 30 to 50 years
  • All sexes
  • No healthy volunteers
  • Adult

Study population: Antiretroviral treatment-naive patients with advanced HIV infection starting a Darunavir/Ritonavir - or Efavirenz-based HAART regimen. Patients with advanced HIV infection are defined by a treatment-naïve CD4+ cell count >50 to <250 cells/mm3.

Who may be able to join

  • Documented human immunodeficiency (HIV)-1 infection
  • At baseline plasma blood sampling, has never received antiretroviral therapy
  • Attending the Clinic of Infectious Diseases of the University of Milan at San Paolo Hospital
  • Asymptomatic (demonstrating no acquired immunodeficiency syndrome [AIDS]-defining symptoms) at Baseline, Week 12, and Week 24
  • CD4 cell count >50 to <250/mm3 at Baseline
  • Receiving treatment with either Darunavir/Ritonavir + Tenofovir/Emtricitabina or Efavirenz + Tenofovir/Emtricitabina highly active antiretroviral therapy (HAART) regimens at Week 12, Week 24, and Week 48 plasma blood sampling.

Who cannot join

None listed.

About this study

Official title: Ex Vivo Study of Immune-Reconstitution Kinetics in HIV-infected ARV-naive Subjects, With Advanced Disease, Starting a Darunavir/Ritonavir or Efavirenz Based HAART (IMMUNO Study)

The purpose of this study is to study the kinetics (study of the rate of change) of immune recovery quality and function in stored plasma blood samples of treatment-naive (not previously treated with antiretroviral drugs) patients with advanced human immunodeficiency virus (HIV) infection starting a Darunavir/Ritonavir- or Efavirenz-based highly active antiretroviral therapy (HAART) regimen.

Read the detailed description

This is an ex-vivo study (study which takes place outside the organism and records immune parameters from stored blood and cells of a defined population without any intervention by the researcher) to evaluate the kinetics (study of the rate of change) of immune recovery quality and function in stored plasma blood samples of treatment-naive (not previously treated with antiretroviral drugs) patients with advanced human immunodeficiency virus (HIV) infection starting a Darunavir/Ritonavir (DRV/r)- or Efavirenz (EFV)-based highly active antiretroviral therapy (HAART) regimen. In previously stored plasma blood samples, the role of DRV/r compared with EFV in reducing T-lymphocyte activation, DRV/r compared with EFV in recovering T-lymphocyte immune phenotype in peripheral blood and thymic production, and DRV/r compared with EFV in recovering T-lymphocyte function (functional immunity) will be studied. Blood samples will be analyzed before (baseline) and up to 48 weeks after initiating HAART.

Each patient will receive orally administered (given by mouth) regimens of either Darunavir/Ritonavir (DRV/r) + Tenofovir/Emtricitabina or Efavirenz (EFV) + Tenofovir/Emtricitabina.

Being tested

What is being measured

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

  1. Change (>=10%) in the proportion of activated HLA-DR+CD38+CD8+ T-cells

    Measured: Baseline and Week 24

Secondary outcomes (3)
  1. Change (>=10%) in the proportion of activated HLA-DR+CD38+CD8+ T-cells

    Measured: Baseline, Week 12, and Week 48

  2. Change in peripheral T-lymphocyte immune phenotype

    Measured: Baseline, Week 12, Week 24 and Week 48

  3. Change in peripheral T-lymphocyte turnover

    Measured: Baseline, Week 12, Week 24 and Week 48

Questions about this trial

What is this clinical trial studying?

An observational study of Human Immunodeficiency Virus; HIV, run by Janssen-Cilag S.p.A..

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 6 inclusion and 0 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 26 Nov 2013. Status can change between updates, so confirm with the study contact before making plans.

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.

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?

Change (>=10%) in the proportion of activated HLA-DR+CD38+CD8+ T-cells (time frame: Baseline and Week 24). 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 26 Nov 2013.
