ClinConnect Summary

Vaccine formulations of synthetic peptides adsorbed to alum may not provide other requisite characteristics of an effective HIV vaccine, such as induction of mucosal immunity, production of cytotoxic T cells, and ease of administration. An oral microparticulate vaccine containing a prototype synthetic peptide has been developed. The microparticles can be degraded over time, inducing both secretory and systemic immune responses.

Twelve volunteers per dose regimen will receive oral microparticulate multivalent HIV-1 peptide vaccine at months 0, 1, and 6, either daily as a low dose for 3 days...

  • Co-existing Condition:
  • Subjects with the following symptoms or conditions are excluded:

  • History of inflammatory gastrointestinal disease, celiac disease, or intestinal malignancy.
  • History of acute gastroenteritis within the past month or gastrointestinal surgery within the past year.
  • History of cancer unless there has been surgical excision with reasonable assurance of cure.
  • History of serious allergic reaction.
  • Prior Medication:
  • Excluded:
  • History of immunosuppressive medications.
  • Live attenuated vaccines within 60 days prior to study entry (NOTE: Medically indicated subunit or killed vaccines, e.g., influenza or pneumococcal, are not exclusionary, but should not be given within 2 weeks of HIV immunization).
  • Experimental agents within 30 days prior to study entry.
  • Prior HIV vaccines.
  • Prior Treatment:
  • Excluded:
  • Blood products or immunoglobulin within the past 6 months.
  • Identifiable higher risk behavior for HIV infection, including the following:
  • History of injection drug use within the past 12 months.
  • Higher risk sexual behavior as defined by the AVEG.
