History of Changes
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.

|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|
Further study details as provided by Argos Therapeutics:
Primary Outcome Measures
- 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 ]
- 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. [ Time Frame: 38 weeks ]
- 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) [ Time Frame: 38 weeks (62 weeks for subjects continuing ATI in Step 4) ]
- 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) [ Time Frame: 38 weeks (62 weeks for subjects continuing ATI in Step 4) ]
- Evaluate AGS-004 versus Placebo for change from Baseline in TEAEs, clinical laboratory evaluations, and clinical assessments. [ Time Frame: 2 years ]
- Evaluate AGS-004 versus Placebo for change in inflammatory markers over treatment period and ATI [ Time Frame: 38 Weeks (62 weeks for subjects continuing ATI in Step 4) ]
- Study immunogenicity and mechanism of action by evaluating AGS-004 versus Placebo for change from Baseline in T-cell response. [ Time Frame: 2 years ]
- Study immunogenicity and mechanism of action by evaluating AGS-004 versus Placebo for change from Baseline of the extent of viral evolution. [ Time Frame: 2 years ]
- Study immunogenicity and mechanism of action by evaluating AGS-004 versus Placebo for change from Baseline in the chromosomally integrated viral reservoir. [ Time Frame: 2 years ]
