Description

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. Twenty-eight volunteers are randomized to receive two 0.5 ml injections of C4-43 peptides in IFA or placebo (IFA alone) administered intramuscularly at 0, 1, 6, and 12 months. At ...

Eligibility criteria

  • Inclusion Criteria
  • 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.
  • Exclusion Criteria
  • 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:
  • 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.
  • Experimental agents within 30 days prior to study.
  • HIV-1 vaccines or placebo, received in a previous HIV vaccine trial.
  • Immunosuppressive medications.
  • Prior Treatment:
  • Excluded:
  • Receipt of blood products or immunoglobulin in the past 6 months.
  • Risk Behavior: Excluded:
  • Alcohol intake greater than or equal to the equivalent of 1 oz of 100 proof per day (4 oz. glass of wine or 12 oz. of beer per day).
  • Identifiable higher-risk behavior for HIV infection as determined by screening questions designed to identify risk factors for HIV infection; specific exclusions include a history of injection drug use within the last 12 months prior to enrollment and higher- or immediate-risk sexual behavior as defined by the AVEG (i.e., meeting the criteria for AVEG Risk Groups C and D).
