Detailed Description:

This study will evaluate the safety, tolerability, and efficacy of the VRC01 antibody in preventing HIV-1 infection in healthy women at high risk of HIV infection.

Participants will be enrolled from a cohort of heterosexual women in sub-Saharan Africa. An equal number of study participants will be randomized to receive VRC01 mAb by IV infusion at a dose of 10 mg/kg or 30 mg/kg every 8 weeks, or to receive control infusions every 8 weeks. All participants will receive the VRC01 antibody or placebo by intravenous infusion at Weeks 0 (study entry), 8, 16, 24, 32, 40, 48, 56, 64, and 72. For 3 days following each infusion, participants will be asked to record and report any symptoms to study researchers.

In addition to the infusion visits, participants will attend study visits at Weeks 4, 8 + 5 days, 12, 20, 28, 36, 44, 52, 60, 68, 76, 80, 84, 88, and 92. All study visits will include blood collection and HIV testing and counseling. Select study visits will include a medical history review, physical exam, urine collection, pregnancy testing for participants capable of becoming pregnant, risk reduction counseling, and an interview/questionnaire.

Persons who are NOT capable of becoming pregnant due to having undergone total hysterectomy or bilateral oophorectomy (verified by medical records) are not required to undergo pregnancy testing.
  • Reproductive status: A volunteer who is capable of becoming pregnant must agree to consistently use effective contraception (see the protocol and SSP for more information) for sexual activity that could lead to pregnancy from at least 21 days prior to enrollment through the last required protocol clinic visit.

General

  • Investigational research agents received within 30 days before first infusion

    • A condition that requires active medical intervention or monitoring to avert grave danger to the volunteer's health or well-being during the study period; or
    • A condition or process for which signs or symptoms could be confused with reactions to VRC01.
  • Any medical, psychiatric, occupational, or other condition that, in the judgment of the investigator, would interfere with, or serve as a contraindication to, protocol adherence, assessment of safety or infusion reactions, or a volunteer's ability to give informed consent
  • Psychiatric condition that precludes compliance with the protocol. Specifically excluded are persons with psychoses within the past 3 years, ongoing risk for suicide, or history of suicide attempt or gesture within the past 3 years.

  • Seizure disorder: History of seizure(s) within past three years. Also exclude if volunteer has used medications in order to prevent or treat seizure(s) at any time within the past 3 years.
  • History of hereditary angioedema, acquired angioedema, or idiopathic angioedema
