Description

Studies to date indicate that there may be a dose-sparing effect with the use of QS21. In animal studies, when QS21 has been employed as an adjuvant, it shifted both the dose response curve and allowed less antigen to elicit equivalent binding antibody titers to the rgp120 protein. There may also be an acceleration in the course of antibody response after both the first and the second immunizations. Although the final titers in response to vaccine given in both alum and QS21 appear similar after 3 doses in humans, this plateau may be reached more readily, and with a lower antigen dose, when...

  • Patients with any of the following symptoms or conditions are excluded:
  • Medical or psychiatric condition or occupational responsibilities, which preclude subject compliance with the protocol (e.g., recent suicidal ideation or present psychosis).
  • Active syphilis. NOTE: If the serology is documented to be false positive due to a remote (> 6 months) treated infection, the volunteer is eligible).
  • Active tuberculosis. NOTE: Volunteers with a positive PPD and a normal chest X-ray showing no evidence of TB and not requiring INH therapy are eligible.
  • Patients with any of the following prior conditions are excluded:
  • History of immunodeficiency, chronic illness, malignancy, autoimmune disease.

  • History of serious allergic reaction to any substance, requiring hospitalization or emergent medical care.
  • History of suicide attempts or past psychosis.
  • History of reaction to thimerosal.
  • Prior Medication:
  • Excluded:
  • History of use of immunosuppressive medication.
  • Live attenuated vaccines within 60 days of study. NOTE: Medically indicated subunit or killed vaccines (e.g., influenza, pneumococcal) are not exclusionary, but should be given at least 2 weeks away from HIV immunizations.
  • Use of experimental agents within 30 days prior to study.
  • Prior receipt of HIV-1 vaccines or placebo recipient in previous HIV vaccine trial.
  • Prior Treatment:
  • Excluded:
  • Receipt of blood products or immunoglobulin in the past 6 months.
  • Risk Behavior:
  • Excluded:
  • Subjects with identifiable higher-risk behavior for HIV infection as determined by screening questionnaire designed to identify risk factors for HIV infection.
  • History of injection drug use within the last 12 months prior to enrollment.
  • Higher- or intermediate-risk sexual behavior as defined by AVEG.
