2004 NOV 3 - (NewsRx.com & NewsRx.net) -- Results from a phase I study indicated a human papillomavirus (HPV) type 18 L1 VLP vaccine was safe and immunogenic in women.
"Human papillomavirus (HPV) infection can cause genital warts and cervical cancer. HPV types 6 and 11 cause >90% of genital wart cases; HPV16 and 18 cause 70% of cervical cancers. A prophylactic HPV (types 6, 11, 16, 18) L1 virus-like particle (VLP) vaccine may substantially reduce the incidence of these lesions. This report describes the results of a phase I study of the HPV18 component of such a vaccine," scientists writing in the journal Vaccine report.
"Forty women were randomized to receive either HPV18 L1 VLP vaccine or placebo," said Kevin A. Ault at the University of Iowa and collaborators in the U.S. "Anti-HPV18 responses were measured using a competitive radioimmunoassay (cRIA). Tolerability was evaluated using vaccination report cards (VRC). The study showed that the HPV18 L1 VLP vaccine was generally well-tolerated and highly immunogenic. Peak anti-HPV18 geometric mean titers in vaccines were 60-fold greater ...
