Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
To determine the frequency of delayed-type hypersensitivity (DTH) reactions in HIV-positive patients to two doses of two envelope glycoprotein antigens prepared differently. To determine whether patients who have previously demonstrated a DTH response to intradermal MGStage HIV-1 gp160 IIIB baculovirus (MicroGeneSys) have a reproducible response to a repeat injection of gp160 and whether there is cross-reactivity to intradermal HIV-1 rgp160 IIIB vero cell expressed (Immuno-AG). PER 4/5/95 AMENDMENT: To also determine whether patients who respond to HIV-1 rgp160 IIIB baculovirus (MicroGeneSys) have cross-reactivity to intradermal skin tests of HIV-1 rgp160 MN (Immuno-AG). Previous studies in individuals immunized with gp160 suggest that a skin test response in immunized patients can be used as a surrogate marker for new proliferative and cytotoxic responses induced by vaccination.
