About this study

Official title: A Phase 2, Open Label Study of the Safety, Antiretroviral Activity and Pharmacokinetics of 3BNC117 During a Short Analytical Treatment Interruption in HIV-infected Subjects

This study evaluates the effects of two infusions of 3BNC117 in preventing or delaying rebound of viral load during a brief treatment interruption of standard ART and its safety during a brief analytical interruption of antiretroviral therapy.

Read the detailed description

The proposed study is a Phase II, open label study to evaluate the safety and antiretroviral activity of two and four infusions of 3BNC117 in HIV-infected subjects on combination ART during a brief analytical treatment interruption.

After meeting enrollment criteria sixteen subjects with 3BNC117 sensitive virus (<2μg/ml IC50) will receive two (Group A) or four (Group B) intravenous infusions of 3BNC117, administered at 30 mg/kg.

In both dosing groups, antiretroviral therapy will be discontinued 2 days after the first 3BNC117 infusion (day 2) until week 12. Combination ART will be resumed at week 12. ART will be resumed sooner if plasma HIV-1 RNA level is ≥ 200 copies/ml or if CD4+ count drops < 350 cells/μl and either result is confirmed upon repeat measurement. Participants will be followed weekly until week 12 for safety assessments and for monitoring plasma HIV-1 RNA levels (viral load). CD4+ T cell counts will be monitored every 2 weeks until week 12.

Participants may remain off antiretroviral therapy after week 12, with weekly viral load monitoring, if viral rebound does not occur by week 12. Participants will be followed for a total of 36 weeks.

What is being measured

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

  1. Number of Participants With Virologic Rebound at 8 Weeks After Interruption of Antiretroviral Therapy

    Virologic rebound is defined as confirmed plasma HIV-1 RNA level > 200 copies/ml in two separate occasions

    Measured: 8 weeks

  2. The Rate of Signs, Symptoms and Laboratory Abnormalities After 3BNC117 Infusions

    The percentage of participants who experienced adverse events (e.g. signs, symptoms and laboratory abnormalities) following 3BNC117 infusions.

    Measured: 36 weeks

Secondary outcomes (1)
  1. The Plasma Level of 3BNC117 at the Time of Viral Rebound.

    The plasma concentrations of 3BNC117 at the time of viral rebound (i.e. confirmed plasma HIV-1 RNA levels > 200 copies/ml).

    Measured: 36 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing 3BNC117 and ART Interruption in people with HIV-1 Infection, run by Rockefeller 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 8 inclusion and 23 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 23 Jul 2020. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 23 Jul 2020). 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?

Number of Participants With Virologic Rebound at 8 Weeks After Interruption of Antiretroviral Therapy (time frame: 8 weeks). The study lists 2 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 23 Jul 2020.
