About this study

Official title: The Phase 2, Two Arms, One Site, Safety and Antiviral Activity of Combination Therapy With Albuvirtide and 3BNC117 in Virologically Suppressed Subjects With HIV-1 Infection After Analytical Treatment Interruption

This is a phase 2 study to evaluate the safety and tolerability of combination therapy with Albuvirtide (ABT) and 3BNC117 in virologically suppressed subjects with HIV-1 infection and explore the potential of viral suppression and viral reservoir clearance after analytical treatment interruption (ATI).

Read the detailed description

This is an open-label, one site study, in which a total of 24 HIV-1 subjects who are virologically suppressed and stable on daily oral combination antiretroviral therapy will be enrolled.

All eligible patients will be switched from daily oral combination antiretroviral regimen to treatment of ABT and 3BNC117 for 14 weeks. There is a two-week overlap of the baseline oral antiretroviral therapy and the ABT-3BNC117 combination regimen at the beginning of the study treatment, and then the oral ART will be interrupted.

The patients will be monitored for viral rebound every two or four weeks following initiation of ABT-3BNC117 combination and will re-initiate an oral antiretroviral regimen if virological rebound is confirmed with plasma HIV-1 RNA levels above 200 copies/ml on two consecutive test.

Pharmacokinetics of ABT and 3BNC117 will be assessed in this study.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Albuvirtide and 3BNC117 in people with HIV/AIDS, run by Frontier Biotechnologies Inc. at 1 site in China.

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 19 inclusion and 18 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: status not confirmed, as of the sponsor's last update on 26 Mar 2021. 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 China. 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?

Results are not available in the source record.

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

Contact Xingxiang Xu (025-69648410, xxxu@frontierbiotech.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of participants (with sustained viral suppression at week 14) with HIV-1 RNA < 50 copies/mL at Week 26 (24 weeks after ATI) (time frame: Week 26). 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 Mar 2021.
