About this study

Official title: ANRS EP69 BICTEVOIR : A Prospective Study to Determine the Cartography of Virologic Reservoir Related to Antiretroviral Concentrations in HIV-1 Chronic Patients Treated by a First Line Treatment Containing bictégravir, Emtricitabine and ténofovir alafénamide

The main objective of the study is to evaluate the diffusion of bictegravir and associated backbone (tenofovir alafenamide and emtricitabine) in HIV-1 chronic patients in the main putative reservoirs, namely inguinal lymph nodes, rectal, fat tissues and sperm.

Read the detailed description

ANRS EP69 BICTEVOIR is an interventional pilot study, multicenter, involving the use of human biological samples.

34 HIV-1 infected male subjects, from Bicetre, La Pitié Salpêtriere, Antoine-Béclère, Necker, Hôtel-Dieu and Saint-Antoine Hospitals will be recruited.

Different samples will be performed during one single day:

  • blood samples
  • rectal biopsies
  • nodes biopsies
  • cutaneous fat tissues biopsies
  • semen sample (at home)
Conditions
HIV-1-infection
Being tested
Biopsies and bloood samplings

What is being measured

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

  1. Characterization of the diffusion of bictegravir and associated backbone (tenofovir alafenamide and emtricitabine) in sperm

    Dosage of the different antiretroviral drugs molecules in sperm

    Measured: At Day 0, At time T0 (before taking treatments)

  2. Characterization of the diffusion of bictegravir and associated backbone (tenofovir alafenamide and emtricitabine) in lymph nodes

    Dosage of the different antiretroviral drugs molecules in lymph nodes

    Measured: At Day 0, between T1 (maximum 3 hours after tacking treatments) and T3 (8 hours after taking treatments)

  3. Characterization of the diffusion of bictegravir and associated backbone (tenofovir alafenamide and emtricitabine) in fat tissues

    Dosage of the different antiretroviral drugs molecules in fat tissues

    Measured: At Day 0, between T1 (maximum 3 hours after tacking treatments) and T3 (8 hours after taking treatments)

  4. Characterization of the diffusion of bictegravir and associated backbone (tenofovir alafenamide and emtricitabine) in rectal tissues

    Dosage of the different antiretroviral drugs molecules in rectal tissues

    Measured: At Day 0, T1 (maximum 3 hours after taking treatment)

Secondary outcomes (5)
  1. Characterization of the level of the replication (RNA-HIV) in the reservoirs

    Analyze and comparison of the level of viral transcription by measuring the cell-associated HIV- RNA in the different tissues and fluids: lymphoid, rectal, genital secretion, blood and fat biopsies as well as cerebrospinal fluid.

    Measured: At Day 0

  2. Characterization of the level of infection (DNA-HIV) in the reservoirs

    Analyze and comparison of the reservoir level by measuring the cell-associated total HIV- DNA in the different tissues and fluids

    Measured: At Day 0

  3. Study of the spatial dynamics of viral quasi-species In the different reservoirs

    Analyze of the spatial dynamics of HIV-DNA and HIV-RNA from Lymphoid, rectal, genital secretion, blood, fat cells by phylogenetic analyses after sequencing Env HIV-DNA and HIV-RNA

    Measured: At Day 0

  4. Study of the mutations of resistance in the integrase gene

    Description of resistance mutations in Integrase gene which could be linked to suboptimal concentrations of bictegravir

    Measured: At Day 0

  5. Description for each compartment of the relationship between exposure to therapeutic combinations and the level of infection / viral replication

    Characterization of the relationship between the concentration of bictegravir and backbone drugs with the level of wild type viral replication in the different compartments. Analyze of the impact of backbone drugs associated to bictegravir on viral level production. Correlation between the level of resistant virus replication and the exposure to bictegravir and the backbone drugs. Evaluation by simulation the effect of different dosing regimen of bictegravir (including higher doses) on the level of viral replication and on resistance

    Measured: At Day 0

Questions about this trial

What is this clinical trial studying?

A study testing Biopsies and bloood samplings in people with HIV-1-infection, run by ANRS, Emerging Infectious Diseases at 6 sites in France.

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 7 inclusion and 7 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: opening soon, as of the sponsor's last update on 5 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in France. 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.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Fatoumata Coulibaly (+331 44 23 61 10, fatoumata.coulibay@inserm.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Characterization of the diffusion of bictegravir and associated backbone (tenofovir alafenamide and emtricitabine) in sperm (time frame: At Day 0, At time T0 (before taking treatments)). The study lists 4 primary outcomes in all. 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 5 Feb 2025.
