Summary

Background: Human immunodeficiency virus (HIV) is a global health threat. The body uses antibodies to fight infection. VRC07-523LS is an antibody directed against HIV. It may be used to prevent mother-to-child transmission of HIV. It may also prevent sexual transmission of HIV and treat HIV-1 infected people. Objective: To test the safety, tolerability, dose, and pharmacokinetics of VRC07-523LS in healthy adults. Eligibility: Healthy people ages 18-50 Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Participants will be assigned to 1 of 7 groups: Groups 1-5 will get the drug at 1 visit and then be observed for 24 weeks. Groups 6 and 7 will get the drug at 1 visit every 12 weeks, for a total of 3 doses over 48 weeks. Participants will get the drug in 1 of 2 ways: Infusion into a vein over at least 30 minutes. Participants will have blood tests 1, 3, and 6 hours after the infusion. They will have 1-3 visits during that week. Those in Group 7 will have 4-5 visits in the week after their second and third doses. Injection into the fatty tissue under the skin. Participants will have blood tests before the injection. They will have 1-3 visits during that week. Those in Group 6 will have 4-5 visits after the second and third doses. Visits include: Physical exam Blood and urine tests Optional oral swabs to collect saliva Participants will keep a diary of their temperature and symptoms for 3 days after each dose.

Eligibility Criteria

  • INCLUSION CRITERIA:

A volunteer must meet all of the following criteria:

  • Able and willing to complete the informed consent process.
  • 18 to 50 years of age.
  • Based on history and examination, must be in good general health and without history of any of the conditions listed in the exclusion criteria.
  • Willing to have blood samples collected, stored indefinitely, and used for research purposes.
  • Able to provide proof of identity to the satisfaction of the study clinician completing the enrollment process.
  • Willing to adhere to reduced risk sexual behavior during study participation.
  • Screening laboratory values within 84 days prior to enrollment must meet the following criteria:
  • White Blood Cell (WBC) 2,500-12,000/mm^3.
  • WBC differential either within institutional normal range or accompanied by the Principal Investigator (PI) or designee approval.
  • Platelets = 125,000 - 400,000/mm^3.
  • Hemoglobin within institutional normal range.
  • Creatinine less than or equal to 1.1 x upper limit of normal (ULN).
  • Alanine aminotransferase (ALT) less than or equal to 1.25 x ULN.
  • Negative for HIV infection by the FDA approved method of detection.
  • Female-Specific Criteria:
  • If a woman is of reproductive potential and sexually active with a male partner, then she agrees to use an effective means of birth control from the time of study enrollment until the last study visit, or to be monogamous with a partner who has had a vasectomy.
  • Negative Beta-HCG (human chorionic gonadotropin) pregnancy test (urine or serum) on day of enrollment for women presumed to be of reproductive potential.

EXCLUSION CRITERIA

A volunteer will be excluded if one or more of the following conditions apply:

  • Previous receipt of licensed or investigational monoclonal antibody.
  • Weight >115 kg.
  • Any history of a severe allergic reaction with generalized urticaria, angioedema or anaphylaxis prior to enrollment that has a reasonable risk of recurrence during the study.
  • Hypertension that is not well controlled.
  • Woman who is breast-feeding, or planning to become pregnant during the study participation.
  • Receipt of any investigational study agent within 28 days prior to enrollment.
  • Any other chronic or clinically significant medical condition that in the opinion of the investigator would jeopardize the safety or rights of the volunteer, including but not limited to: diabetes mellitus type I, chronic hepatitis; OR clinically significant forms of: drug or alcohol abuse, asthma, autoimmune disease, psychiatric disorders, heart disease, or cancer.
