NCT00001044

Brief Summary

PRIMARY: To examine the safety and potential improvement in immune responses elicited by combining rsgp120/HIV-1MN with the adjuvant QS-21. SECONDARY: To examine the role of alum in the vaccine/adjuvant formulation; to determine the optimal dose ratio of vaccine to adjuvant; and to obtain initial information on the optimal schedule of administration. AS PER AMENDMENT 07/02/97: To determine the ability of immunization with rsgp120/HV-1MN in combination with QS21 with or without alum to induce an HIV-1 envelope-specific delayed-type hypersensitivity (DTH) response in volunteers who undergo rsgp120/MN skin testing. Immune responses in HIV-uninfected individuals receiving subunit envelope vaccines formulated with alum adjuvant suggest that functional antibodies capable of neutralizing HIV-1 in vitro may be induced, but the titers are relatively low in comparison to those measured in individuals with natural HIV-1 infection. These limitations might be overcome by the addition or substitution of a more suitable adjuvant such as QS-21.

You may qualify if:

  • Subjects must have:
  • Normal history and physical exam.
  • HIV negativity by ELISA within 6 weeks of immunization.
  • CD4 count \>= 400 cells/mm3.

You may not qualify if:

  • Co-existing Condition:
  • Subjects with the following symptoms or conditions are excluded:
  • Hepatitis B surface antigen.
  • Medical or psychiatric condition or occupational responsibilities that preclude compliance.
  • Active syphilis. NOTE: Subjects with serology documented to be false positive or due to a remote (\> 6 months) treated infection are eligible.
  • Active tuberculosis. NOTE: Subjects with a positive PPD and normal chest x-ray showing no evidence of TB and not requiring isoniazid therapy are eligible.
  • Subjects with the following prior conditions are excluded:
  • History of immunodeficiency, autoimmune disease, or use of immunosuppressive medications.
  • History of anaphylaxis or other serious adverse reactions to vaccines.
  • History of allergy to thimerosal.

  • Prior Medication:
  • Excluded:
  • Live attenuated vaccines within 60 days prior to study entry. (NOTE: Medically indicated subunit or killed vaccines, such as influenza or pneumococcal, are allowed but should be given at least 2 weeks prior to HIV immunizations.)
  • Experimental agents within 30 days prior to study entry.
  • +6 more criteria
