Maternal transfer of anti HPV 6 and 11 antibodies upon immunization with the 9-valent HPV vaccine / Ana María Guevara Zambrano
Título : Maternal transfer of anti HPV 6 and 11 antibodies upon immunization with the 9-valent HPV vaccine Tipo de documento : documento electrónico Autores : Ana María Guevara Zambrano, Fecha de publicación : 2019 Títulos uniformes : Human Vaccines & Immunotherapeutics Idioma : Inglés (eng) Palabras clave : Human papillomavirus 9vHPV vaccine recurrent respiratory papillomatosis clinical trial geometric mean titers (GMTs) Resumen : Background: This exploratory analysis was conducted to characterize the level of HPV types 6/11 antibodies in peripartum maternal blood and in cord blood of infants born to women who received 9-valent HPV (9vHPV) vaccine or quadrivalent HPV (qHPV) vaccine in a pivotal efficacy study (V503-001, NCT 00543543). Methods: A total of 21 mother-infant pairs had evaluable HPV 6/11 results available for analysis. HPV6/11 antibodies were assessed using competitive Luminex immunoassay. The distribution of the ratios of infant to mother anti-HPV antibodies (i.e., infant-anti-HPV/mother- anti-HPV) was summarized. Results: All mothers and infants were seropositive to HPV 6 and HPV 11. Anti-HPV 6/11 geometric mean titers (GMTs) in peripartum maternal blood and in cord blood of infant born to study participants were highly correlated. A 100% of infants born to seropositive mothers were also seropositive. The GMT ratios of peripartum maternal blood vs. those in cord blood were HPV 6: 1.23 [0.43, 3.49] and HPV 11: 1.29 [0.54, 3.07] in the 9vHPV vaccine group and HPV 6: 1.33 [0.41, 4.29] and HPV 11: 1.19 [0.45, 3.13] in the qHPV vaccine group, respectively. Conclusions: These results indicate that antibodies induced by the 9vHPV vaccine cross the placenta, which could potentially be beneficial against HPV6/11 infection and related disease such as recurrent respiratory papillomatosis.

Título : Efficacy, immunogenicity, and safety of a 9-valent human papillomavirus vaccine in Latin American girls, boys, and young women Tipo de documento : documento electrónico Autores : Ana María Guevara Zambrano, Fecha de publicación : 2018 Títulos uniformes : Papillomavirus Research Idioma : Inglés (eng) Palabras clave : 9vHPV cervical cancer human papillomavirus persistent infection vaccine Resumen : Background: A 9-valent human papillomavirus (HPV6/11/16/18/31/33/45/52/58; 9vHPV) vaccine was developed to expand coverage of the previously developed quadrivalent (HPV6/11/16/18; qHPV) vaccine. Methods: Efficacy, immunogenicity, and safety outcomes were assessed in Latin American participants enrolled in 2 international studies of the 9vHPV vaccine, including a randomized, double-blinded, controlled with qHPV vaccine, efficacy, immunogenicity, and safety study in young women aged 16–26 years, and an immunogenicity and safety study in girls and boys aged 9–15 years. Participants (N=5312) received vaccination at Day 1, Month 2, and Month 6. Gynecological swabs were collected regularly in young women for cytological and HPV DNA testing. Serum was analyzed for HPV antibodies in all participants. Adverse events (AEs) were also monitored in all participants. Results: The 9vHPV vaccine prevented HPV 31-, 33-, 45-, 52-, and 58-related high-grade cervical, vulvar, and vaginal dysplasia with 92.3% efficacy (95% confidence interval 54.4, 99.6). Anti-HPV6, 11, 16, and 18 geometric mean titers at Month 7 were similar in the 9vHPV and qHPV vaccination groups. Anti-HPV antibody responses following vaccination were higher among girls and boys than in young women. Most (>99%) 9vHPV vaccine recipients seroconverted for all 9 HPV types at Month 7. Antibody responses to the 9 HPV types persisted over 5 years. The most common AEs were injection-site related, mostly of mild to moderate intensity. Conclusions: The 9vHPV vaccine is efficacious, immunogenic, and well tolerated in Latin American young women, girls, and boys. These data support 9vHPV vaccination programs in Latin America, a region with substantial cervical cancer burden.

Título : Antibody persistence and evidence of immune memory at 5 years following administration of the 9-valent HPV vaccine Tipo de documento : documento electrónico Autores : Ana María Guevara Zambrano, Fecha de publicación : 2017 Títulos uniformes : Vaccine Idioma : Inglés (eng) Palabras clave : 9vHPV vaccine Clinical trial Human papillomavirus Immune memory Immunogenicity Resumen : Background: The 9-valent HPV (9vHPV) vaccine was developed to prevent infection and disease related to 9 HPV types (HPV6/11/16/18/31/33/45/52/58) which cause approximately 90% of cervical cancers, HPV-related vulvar, vaginal and anal cancers, and genital warts worldwide. In a pivotal efficacy study, the 9vHPV vaccine prevented infection and disease due to the 9 vaccine types. Duration of protection remains to be determined. Vaccines that induce long-term protection are generally characterized by the generation of immune memory. The purpose of this report is to assess the persistence of HPV antibody response and existence of immune memory at 5 years post-vaccination. Methods:A subset of subjects (N = 150) who received 3 doses of 9vHPV vaccine at day 1, month 2 and month 6 in the pivotal efficacy study continued in a study extension and received a fourth dose of 9vHPV vaccine at month 60. Serum HPV antibody levels were measured pre-dose 4 and at 7 and 28 days post-dose 4 by competitive Luminex immunoassay. Adverse events were assessed using a vaccination report card. Results: HPV antibodies induced following the 3-dose series of 9vHPV vaccine in the base study persisted through month 60 with seropositivity rates ranging from 77.5% to 100%. Geometric mean titers at 1 week and 1 month post-dose 4 were 1.25–4.10 and 1.65–4.88-fold higher, respectively, than levels observed 1 month following the completion of the three-dose primary series. Seropositivity rates were >99% and 100% at 1 week and 1 month post-dose 4, respectively. The fourth dose of 9vHPV vaccine was generally well tolerated. Conclusions: A three-dose regimen of the 9vHPV vaccine induced persistent HPV antibody response through 5 years post-vaccination. Administration of a fourth dose resulted in a strong anamnestic response to all 9 vaccine types. These findings suggest that the efficacy of the 9vHPV vaccine will be long lasting Mención de responsabilidad : Ana Guevara, Robinson Cabello, Linn Woelber, Edson Duarte Moreira Jr, Elmar Joura, Olaf Reich, Christine Shields, Misoo C Ellison, Amita Joshi, Alain Luxembourg Referencia : Vaccine. 2017 Sep 5;35(37):5050-5057.
