A 9-valent human papillomavirus (HPV 6/11/16/18/31/33/45/52/58) virus-like particle (VLP) vaccine (9vHPV) has been proven highly efficacious in preventing anogenital disease related with vaccine HPV types in a pivotal Phase III study in women aged 16 to 26 years. We report here the results of an open-label phase III study conducted to bridge the findings in women age 16 to 26 years to Japanese girls aged 9 to 15 years. All subjects (n = 100) received a 3-dose regimen of 9vHPV vaccine at day 1, month 2 and month 6. Anti-HPV serologic assays were performed at day 1, month 7, month 12, month 24 and month 30. At month 7 (4 weeks after dose 3), 100% of subjects seroconverted for each vaccine HPV type. Increases in geometric mean titers of anti-HPV 6/11/16/18/31/33/45/52/58 in girls were similar to those in Japanese women aged 16 to 26 years in the pivotal phase III study. Persistence of anti-HPV responses was observed through 2 years after dose 3. In addition, administration of 9vHPV vaccine was generally well tolerated in Japanese girls.

A 9-valent human papillomavirus (HPV 6/11/16/18/31/33/45/52/58) virus-like particle vaccine (9vHPV) has been proven highly efficacious in preventing anogenital diseases related to HPV, in a pivotal phase III study for women aged 16-26 years. Here, we report the results of an open-label phase III study conducted to bridge the gap between the findings in women aged 16-26 years and Japanese girls aged 9-15 years. All subjects (n = 100) received a 3-dose regimen of 9vHPV vaccine on day 1 and at months 2 and 6. Anti-HPV serological assays were performed on day 1 and at months 7, 12, 24, and 30. At month 7 (4 weeks after the third dose), 100% of the subjects exhibited seroconversion for each type of HPV. Increases in geometric mean of the titers for anti-HPV 6/11/16/18/31/33/45/52/58 in the subjects were similar to those in Japanese women aged 16-26 years in a previous phase III study. Persistence of the anti-HPV response was observed for 2 years after administration of the third dose. In addition, administration of the 9vHPV vaccine was generally well-tolerated in Japanese girls.

Human papillomavirus (HPV)-associated disease is common among men with HPV infection. A quadrivalent HPV (qHPV) vaccine has demonstrated 85.9% efficacy against HPV6/11/16/18-related, persistent (≥ 6 month) infection in a study of Japanese men aged 16–26 years old. Here, we report the results of an open-label study of the immunogenicity and tolerability of the qHPV vaccine (NCT02576054), conducted to bridge findings from Japanese men to Japanese boys aged 9–15 years old. A total of 100 boys completed a three-vaccination regimen (Day 1, and Months 2 and 6), and 99 boys were included in the primary analysis population. The rate of seroconversion at one month after vaccine Dose 3 (Month 7) was high for each type of HPV (anti-HPV6/11/16/18 seroconversion rates [95% CI]: 94.9% [85.5%, 98.3%], 99.0% [94.4%, 100.0%], 99.0% [94.5%, 100.0%], and 99.0% [94.4%, 100.0%], respectively). Moreover, anti-HPV6/11/16/18 geometric mean titers were 482.9 mMU/mL, 1052.8 mMU/mL, 3878.3 mMU/mL, and 1114.5 mMU/mL, respectively. Immune responses to the qHPV vaccine were non-inferior among Japanese boys included in the current study and compared with young Japanese men from a separate study. Injection-site reactions were the most common adverse events, and administration of the vaccine was well tolerated in Japanese boys.
