Summary

The purpose of this study was to evaluate the safety, tolerability, and effect of an experimental human monoclonal antibody (mAb), VRC-HIVMAB060-00-AB (VRC01), in adults infected with HIV who were receiving antiretroviral therapy (ART).

Detailed Description

Monoclonal antibodies (mAbs) have been developed as treatment for a variety of conditions including cancer, autoimmune disorders, and infections. mAbs may also be a potential treatment for people infected with HIV. The purpose of this study was to evaluate the safety and tolerability of an experimental human mAb, VRC-HIVMAB060-00-AB (VRC01), in HIV-infected adults receiving ART. Study researchers will also evaluate the effect of VRC01 on the number of infected cells containing unspliced HIV-1 transcripts in the blood in participants. This study enrolled HIV-infected people 18 to 65 years old, who had been receiving ART for at least 2 years and who had a CD4+ count of 200 cells/mm\^3 or greater. Participants were randomly assigned to Arm A or Arm B. Participants in Arm A received an intravenous (IV) infusion of VRC01 at Day 0 and Week 3 and an IV infusion of placebo (normal saline) at Weeks 6 and 9. Participants in Arm B received an IV infusion of placebo (normal saline) at Day 0 and Week 3 and an IV infusion of VRC01 at Weeks 6 and 9. Participants recorded their temperature and symptoms for 3 days after each infusion. Study visits occured at study entry (Day 0), and Weeks 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 15, 18, and 30. Study visits included physical examinations, clinical assessments, and blood collection. The primary safety outcome for this study was descriptive and assessed the occurrence of Grade ≥ 3 AEs including signs/symptoms, lab toxicities, and/or clinical events that are possibly, probably, or definitely related to study treatment (as judged by the core team, blinded to treatment arm) at any time from the initial dose of study treatment to the end of study follow-up. Since this outcome is descriptive, no statistical significance testing was performed.

Inclusion Criteria

•HIV-1 infection, documented by any FDA-approved rapid HIV test or HIV enzyme or chemiluminescence immunoassay (E/CIA) test kit at any time prior to study entry and confirmed by a licensed Western blot or a second antibody test by a method other than the initial rapid HIV or E/CIA tests, or by HIV-1 antigen, or plasma HIV-1 RNA assay. More information on this criterion is available in the protocol.
•Received continuous ART for at least 2 years (defined as no interruptions longer than 14 consecutive days) and with no changes in the components of the ART for at least 90 days prior to study entry
•CD4+ cell count greater than or equal to 200 cells/mm\^3 obtained within 60 days prior to study entry in a clinical laboratory improvement amendments (CLIA)-certified laboratory
•Plasma HIV-1 RNA below the limit of detection of the FDA-approved assays (limit of detection: 75, 50, 40 or 20 copies/mL) for greater than or equal to 2 years on ART. Participants must have had at least one documented HIV-1 RNA less than the limit of detection 12-24 months prior to study entry and at least one HIV-1 RNA less than the limit of detection within 12 months prior to study entry. All available HIV-1 RNA measurements must have been below the assay limit of detection during the 2 years prior to study entry except as allowed by the following note. NOTE: A single unconfirmed plasma HIV-1 RNA greater than the limit of detection but less than 200 copies/mL within 6-24 months was allowed if followed by a subsequent value below the limit of detection.
•Plasma HIV-1 RNA level of less than 40 copies/mL obtained by the Abbott Real-time HIV assay (m2000) or less than 20 copies/mL obtained by the Roche COBAS Taqman HIV-1 v2.0 assay within 60 days prior to entry
•The following laboratory values obtained within 60 days prior to entry by any U.S. laboratory that has a CLIA certification or its equivalent.
•* Absolute neutrophil count (ANC) greater than or equal to 750 cells/mm\^3
•* Hemoglobin greater than or equal to 11.0 g/dL for men and greater than or equal to 10.0 g/dL for women
•* Platelet count greater than or equal to 100,000/mm\^3
•* Creatinine clearance greater than or equal to 60 mL/min estimated by the Cockcroft-Gault equation. NOTE: A program for calculating creatinine clearance by the Cockcroft-Gault method is available on www.fstrf.org.

Exclusion Criteria

•Previous receipt of humanized or human monoclonal antibody (licensed or investigational)
•Weight greater than 115 kg or less than 53 kg
•Acute or ongoing AIDS-defining illness within 60 days prior to study entry
•History of a severe allergic reaction with generalized urticarial, angioedema, or anaphylaxis within 2 years of study entry
•Currently breastfeeding or pregnant
•Active drug or alcohol use or dependence that, in the opinion of the site investigator, would interfere with adherence to study requirements
•Acute or serious illness that, in the opinion of the site investigator, requires systemic treatment and/or hospitalization within 60 days prior to entry
•Use of immunomodulators (e.g., interleukins, interferons, cyclosporine), HIV vaccine, systemic cytotoxic chemotherapy, or investigational therapy within 60 days prior to study entry. NOTE: Participants receiving stable physiologic doses of glucocorticoids, defined as the equivalent of prednisone less than or equal to 10 mg/day, will not be excluded. Stable physiologic glucocorticoid doses should not be discontinued for the duration of the study. In addition, participants receiving inhaled or topical corticosteroids will not be excluded.
•Treatment for hepatitis C within 24 weeks of study entry
•Vaccinations within 7 days prior to the screening, pre-entry, or study entry visits. NOTE: Participants are encouraged to get routine vaccinations, such as seasonal influenza vaccine more than 7 days prior to screening or between screening and pre-entry visits (outside of the 7-day window above).
