Brief Summary

To evaluate the safety of HIV-1 gp120 C4-V3 hybrid polyvalent peptide immunogen (C4-V3 peptides) formulated in mineral oil containing mannose mono-oleate (IFA) in HIV-1 uninfected volunteers. To evaluate the humoral and cellular immune responses to the C4-V3 peptides as measured by the induction of 1 or more of the following: neutralizing antibodies to HIV-1 MN and RF, cross-neutralizing antibodies to primary isolates of HIV-1, HIV-1 antigen-specific lymphoproliferation, CD8+ and CD4+ cytotoxic T lymphocyte (CTL) activity specific for HIV-1 gp120 or V3 peptides corresponding to the vaccine strains of HIV-1, induction of HLA-B7 and HLA-A2 restricted CD8+CTLs, and induction of HIV-specific DTH responses. The test immunogen (C4-V3 peptides) is constructed from 4 sequences of the HIV-1 V3 gp120 loop shared by approximately 80% of North American HIV-1 strains. Because of the critical role that this region plays in generating anti-HIV sequences, it is hypothesized that the test immunogen (C4-V3 peptides) will be capable of inducing a broad range of cross-reactive neutralizing antibodies in the majority of recipients.

Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Volunteers must have:
  • Negative ELISA for HIV within 8 weeks of immunization.
  • Normal history and physical examination.
  • Normal chest x-ray within 4 weeks prior to initial immunization.
  • Low-risk sexual behavior as defined by AVEG.

You may not qualify if:

  • Co-existing Condition:
  • Volunteers with the following conditions are excluded:
  • Medical or psychiatric condition that precludes compliance with the protocol, including recent suicidal ideation or present psychosis.
  • Occupational responsibilities which preclude compliance with the protocol.
  • Active syphilis (if the serology is documented to be a false positive or due to a remote \[more than 6 months\] treated infection, the volunteer is eligible).
  • Active tuberculosis (volunteers with a positive purified protein derivative and a normal chest x-ray showing no evidence of TB and not requiring isoniazid therapy are eligible).
  • Positivity for hepatitis B surface antigen.
  • Volunteers with the following prior conditions are excluded:
  • History of immunodeficiency, chronic illness, malignancy, or autoimmune disease. NOTE: Individuals with a history of cancer are excluded unless there has been surgical excision followed by a sufficient observation period to give a reasonable assurance of cure.
  • History of suicide attempts or past psychosis.
  • History of anaphylaxis or other serious adverse reactions to vaccines.
  • History of serious allergic reaction to any substance, requiring hospitalization or emergent medical care (e.g., Stevens-Johnson syndrome, bronchospasm, or hypotension).
  • History of lung disease.
  • Prior Medication:
  • Excluded:
  • +8 more criteria
