About this study

Official title: A Randomized, Double-Blind, Phase 2B Study Testing the Efficacy and Safety of AGS-004 on Host Control of HIV Replication During Analytical Treatment Interruption

The purpose of this study is to determine the safety and effectiveness of AGS-004, an immune therapy, for HIV-infected individuals. Safety and effectiveness will be tested while the individuals are both taking antiretroviral therapy (ART) medication and interrupting ART medication.

What is being measured

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

  1. Compare the anti-HIV effects of AGS-004 versus Placebo as measured by new HIV Viral Load setpoint after a 12 week Analytical Treatment Interruption

    Measured: 38 weeks

Secondary outcomes (8)
  1. Evaluate AGS-004 versus Placebo for change in plasma HIV Viral Load levels from the value just before initiation of ART to the value at the end of the 12 week ATI.

    Measured: 38 weeks

  2. Evaluate AGS-004 versus Placebo for change from Baseline in CD4 T-Cell absolute and percentage values at Week 26 and at the end of Step 4 (for subjects continuing ATI)

    Measured: 38 weeks (62 weeks for subjects continuing ATI in Step 4)

  3. Evaluate AGS-004 versus Placebo for effects on HIV viral kinetics during the 12 week ATI, as measured my mean or median levels of plasma HIV Viral Load; assessed throughout and at the end of Step 4 (for subjects continuing ATI)

    Measured: 38 weeks (62 weeks for subjects continuing ATI in Step 4)

  4. Evaluate AGS-004 versus Placebo for change from Baseline in TEAEs, clinical laboratory evaluations, and clinical assessments.

    Measured: 2 years

  5. Evaluate AGS-004 versus Placebo for change in inflammatory markers over treatment period and ATI

    Measured: 38 Weeks (62 weeks for subjects continuing ATI in Step 4)

  6. Study immunogenicity and mechanism of action by evaluating AGS-004 versus Placebo for change from Baseline in T-cell response.

    Measured: 2 years

  7. Study immunogenicity and mechanism of action by evaluating AGS-004 versus Placebo for change from Baseline of the extent of viral evolution.

    Measured: 2 years

  8. Study immunogenicity and mechanism of action by evaluating AGS-004 versus Placebo for change from Baseline in the chromosomally integrated viral reservoir.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing AGS-004 in people with HIV Infection, run by Argos Therapeutics at 9 sites in 2 countries.

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 27 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 24 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United States, Canada. 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. Some participants in this study may receive a placebo. 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?

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?

Compare the anti-HIV effects of AGS-004 versus Placebo as measured by new HIV Viral Load setpoint after a 12 week Analytical Treatment Interruption (time frame: 38 weeks). 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 24 Jan 2017.
