Unique Identifier : AIDSLINE MED/96066231 AB In this Phase I study, immunisation with the yeast-derived p24 virus-like particles Ty p24-VLP (3 x 100 or 3 x 500 micrograms subcutaneously) in 16 healthy male subjects elicited p24 antibody responses in 4 of 16 (25%) subjects. After a fourth, intramuscular, immunisation (500 micrograms), p24 antibody responses were detected in 11 of 15 (70%) subjects. In addition to p24 antibody responses, T cell proliferative responses were also observed, although no HLA restricted p24-specific cytotoxic T cell responses were detected. The results demonstrate that Ty p24-VLP is immunogenic and well-tolerated in healthy male subjects.
