2001 NOV 7 - (NewsRx.com & NewsRx.net) -- Xenova Group plc (XNVA), had announced results from the Phase II clinical efficacy trial conducted in collaboration with its partner, GlaxoSmithKline (GSK), with TA-HSV, a therapeutic vaccine designed for the treatment of genital herpes.
Analysis has shown that the trial has not met its clinical endpoints. The multicenter, placebo-controlled study was conducted among 483 herpes simplex virus (HSV)-2 seropositive patients with symptomatic recurrent genital herpes. No significant difference was seen between the treatment arm and the control group with respect to time to first recurrence, the total number of recurrences or other clinical outcomes assessed during the course of the study. Further development by GSK of the therapeutic vaccine TA-HSV is not planned and the TA-HSV development agreement between the two companies will be terminated effective January 2002.
Xenova will continue to develop DISC-PRO, a prophylactic vaccine designed to prevent genital and orolabial herpes. Xenova holds all rights to DISC-PRO.
