These studies were performed to determine the effects of GPI-0100, a semi synthetic Quillaja Saponin analog, formulated with herpes simplex virus type-1 (HSV-1) glycoprotein D (gD) on immunity to HSV. SKH-1 hairless mice, used as a model of herpes labialis, inoculated with HSV-1 results in facial lesions, virus replication and mortality. Mortality rates, lesion scores and viral titers were significantly reduced in SKH-1 mice immunized with gD/GPI-0100 prior to cutaneous inoculation with HSV-1 and the protective effects were greater than those using the standard alum adjuvant. Genital HSV-2 infections in guinea pigs were also utilized to determine if gD combined with GPI-0100 was protective against infection, disease severity and viral shedding. Guinea pigs immunized with HSV-1 gD with or without GPI-0100 had significantly reduced area under the curve lesion scores, but infection rates and virus shedding was not altered. When Tween 40 was added to gD and GPI-0100, mean peak lesion scores were also significantly reduced. The results obtained in a genital HSV-2 infection of guinea pigs did not indicate enhanced protection or reduced virus shedding following immunization with GPI-0100 and gD. There was, however, a significant improvement in clinical herpetic genital disease with the combination of gD plus the immune enhancer GPI-0100. (c) 2005 Elsevier Ltd. All rights reserved.
