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).

Eligibility Criteria

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.
  • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) (SGPT) less than or equal to 2.0 times upper limit of normal (ULN)
  • Hepatitis C virus (HCV) antibody negative result within 60 days prior to study entry or, if the HCV antibody result is positive, a negative HCV RNA result within 60 days prior to study entry
  • Negative HBsAg result obtained within 60 days prior to study entry
  • Ability and willingness of participant to provide informed consent
  • Females of reproductive potential (women who have not been post-menopausal for at least 24 consecutive months, i.e., who have had menses within the preceding 24 months, or women who have not undergone surgical sterilization, specifically hysterectomy, or bilateral oophorectomy and/or bilateral salpingectomy), needed a negative serum or urine pregnancy test within 48 hours prior to study entry. NOTE: Acceptable documentation of hysterectomy and bilateral oophorectomy, bilateral salpingectomy, tubal micro-inserts, partner who has undergone vasectomy, and menopause is participant-reported history.
  • All participants must have agreed not to participate in the conception process (e.g., active attempt to become pregnant or to impregnate, sperm donation, in vitro fertilization), and if participating in sexual activity that could lead to pregnancy, the participant/partner must use at least one reliable form of contraception (condoms, with or without a spermicidal agent; a diaphragm or cervical cap with spermicide; an intrauterine device (IUD); or hormone-based contraceptive), while receiving study treatment and for 12 weeks after stopping study
