About this study

Official title: ART Persistence: Antiretroviral Drug Persistence in Different Body Compartments in HIV Negative Men Who Have Sex With Men

The study seeks to understand how anti-HIV drug Biktarvy, which contains the drugs tenofovir alafenamide (TAF), emtricitabine (FTC), and bictegravir (BIC) is absorbed and how long it persists in different body compartments, including mucosal tissues, as it may be considered for PrEP or PEP regimens in the future.

Read the detailed description

Men who have sex with men (MSM) continue to be disproportionately affected by HIV. The majority of MSM acquire HIV after exposure to the rectal mucosa through receptive anal intercourse without condoms. Pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) are recommended for MSM who may be exposed to HIV to prevent infection. Current recommendations for PrEP are to take the combination anti-HIV drug, tenofovir+emtricitabine (TDF/FTC), on a daily basis for the duration of someone's HIV risk exposure period, which could be months or years. For PEP, a three-drug anti-HIV medication is recommended within 72 hours of a possible exposure for a 28-day course. While PrEP and PEP are effective, some people find it difficult to follow the recommended regimen. Therefore, additional short-course dosing regimens for PrEP and PEP are being considered for future development. The study drug provided in this study will not protect participants from HIV or treat any active infection. This proposal seeks to understand how other anti-HIV medications are absorbed and how long they persist in different body compartments, including mucosal tissues, as they may be considered for PrEP or PEP regimens in the future.

Participants will be sequentially enrolled into study arms. All participants will take two doses of Biktarvy and then will have biological samples collected at different time points. Blood will be collected at three different time points and a rectal biopsy will occur once. Participants may participate in more than one study arm or subgroup; however, at least 6 weeks must lapse after completion of one study arm or subgroup, before entry into another.

Median drug levels of TAF, FTC, and BIC in plasma, peripheral blood mononuclear cells (PBMCs) and rectal tissues will be calculated at baseline, 24 hours after the first dose and 120 hours after the first dose as the primary outcomes of this study. Samples collected at other time points will be stored for future exploratory analyses.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • BiktarvyDrug

    Also called BIC/FTC/TAF

    Participants will be given two doses of the oral fixed dose combination anti-HIV medication Biktarvy (BIC/FTC/TAF) separated by 24 hours. The first dose is given in the clinic and participants are instructed to take the second dose at home, 24 hours after the first dose.

Study groupRoleWhat they receive
Sample collection 2, 48, and 96 hours after first dose of BiktarvyExperimentalParticipants in this study arm (Arm A) will provide biological specimens 2, 48, and 96 hours after the in-clinic dose of Biktarvy. Approximately 24 mL of blood will be drawn, an oral cheek swab, 1 pre-wet penile swab and 1 dry penile swab, and a urethral swab will be collected. After previous swab collections are complete, participants will be asked to provide a urine sample (some of which will be used for gonorrhea and chlamydia testing). Participants will undergo rectal biopsy collection at one of the study visits.

What is being measured

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

  1. Median Drug Levels in Plasma

    Median drug levels of tenofovir (TFV), emtricitabine (FTC), and bictegravir (BIC) in plasma were determined. Concentrations below the limit of quantification (LOQ) are assigned a value of zero. The prespecified outcomes of interest are plasma concentrations of the components of Biktarvy at 24 and 120 hours after the initial dose. All other time points of sample collection are for future exploratory analyses and have not been analyzed. Only the time points of sample collection that were prespecified as primary study outcomes are presented here.

    Measured: Baseline (pre-dosing), 24 hours after the first dose, and 120 hours after first dose

  2. Median Drug Concentration in Peripheral Blood Mononuclear Cells (PBMCs)

    Median drug concentrations of tenofovir-diphosphate (TFV-DP) and emtricitabine-triphosphate (FTC-TP) in PBMCs were determined. Concentrations below the limit of quantification (LOQ) are assigned a value of zero. The prespecified outcomes of interest are PBMC concentrations of the components of Biktarvy at 24 and 120 hours after the initial dose. All other time points of sample collection are for future exploratory analyses and have not been analyzed. Only the time points of sample collection that were prespecified as primary study outcomes are presented here.

    Measured: Baseline (pre-dosing), 24 hours after the first dose, and 120 hours after first dose

  3. Median Drug Levels in Rectal Tissues

    Median drug levels of TFV, FTC, and BIC in rectal tissue were determined. Concentrations below the limit of quantification (LOQ) are assigned a value of zero. The prespecified outcomes of interest are rectal tissue concentrations of the components of Biktarvy at 24 and 120 hours after the initial dose. All other time points of sample collection are for future exploratory analyses and have not been analyzed. Only the time points of sample collection that were prespecified as primary study outcomes are presented here.

    Measured: Baseline (pre-dosing), 24 hours after the first dose, and 120 hours after first dose

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Biktarvy in people with ART and HIV, run by Emory University at 1 site in United States.

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 11 inclusion and 28 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 22 Feb 2022. 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 States. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 22 Feb 2022). 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?

Median Drug Levels in Plasma (time frame: Baseline (pre-dosing), 24 hours after the first dose, and 120 hours after first dose). The study lists 3 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 22 Feb 2022.
