Long-term effectiveness of the nine-valent human papillomavirus vaccine: Interim results after 12 years of follow-up in Scandinavian women. Hum Vaccin Immunother 2024; 20:2377903. [PMID: 39373579 PMCID: PMC11459749 DOI: 10.1080/21645515.2024.2377903] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2024] [Revised: 06/26/2024] [Accepted: 07/05/2024] [Indexed: 10/08/2024] Open
Abstract
A pivotal study in women aged 16-26 years demonstrated that the nine-valent human papillomavirus (9vHPV) vaccine was efficacious against high-grade cervical dysplasia related to the HPV types covered by the vaccine. To evaluate whether effectiveness remains above 90% for up to 14 years post-vaccination, a long-term follow-up (LTFU) extension of the study was conducted in Denmark, Norway, and Sweden (N = 2,029). Interim findings at 12 years post-vaccination are reported. Effectiveness of the vaccine was measured by comparing the percentage reduction in incidence of HPV16/18/31/33/45/52/58-related high-grade cervical dysplasia in the LTFU cohort with the expected incidence in an unvaccinated cohort. Cervical pre-cancer/cancer diagnoses were identified using national health registries. Tissue samples were obtained from national and regional biobanks for polymerase chain reaction HPV testing, and pathology diagnosis adjudication. Potential waning of vaccine effectiveness and statistical significance were assessed using a control chart method. During LTFU, there were no cases of HPV16/18/31/33/45/52/58-related high-grade cervical dysplasia over 10,396.2 person-years' follow-up in the per-protocol effectiveness population (n = 1,628). No signals indicated vaccine effectiveness decreasing below 90%. Statistically significant protection was provided by the 9vHPV vaccine through at least 10 years, with complete, although not statistically significant, effectiveness through 12 years.

Abstract
BACKGROUND International data on anogenital HPV infection incidence among men are limited. METHODS Incidence of incident-persistent (IP) anogenital HPV infections was evaluated among 295 men who have sex with men (MSM) and 1576 heterosexual men (HM) aged 16-27 years in the placebo arm of a global, multicenter 4-valent (4v) HPV vaccine trial. We estimated IP incidence (penile/scrotal, perineal/perianal, anal) for 4vHPV and 9-valent (9v) HPV vaccine types and cumulative IP incidence over 36 months. RESULTS IP infection incidence per 100 person-years (95% CI) among HM for 4vHPV and 9vHPV types was 4.1 (3.5-4.9) and 6.8 (5.9-7.6) at penile/scrotal, and 1.2 (.8-1.6) and 1.9 (1.5-2.4) at perineal/perianal sites, respectively; and among MSM, IP infection incidence was 2.3 (1.3-3.8) and 3.2 (2.0-4.9) at penile/scrotal, 6.8 (4.9-9.2) and 9.0 (6.9-11.6) at perineal/perianal, and 12.0 (9.4-15.1) and 16.8 (13.7-20.2) at anal sites, respectively. Cumulative IP incidence over 36 months (excluding anal canal; any 9vHPV type) was higher among MSM versus HM (24.1% vs 18.4%). CONCLUSIONS A substantial proportion of unvaccinated men of catch-up vaccination age developed IP 9vHPV-related infections. Gender-neutral vaccination could decrease male HPV infection, contribute to herd protection, and reduce disease burden. Clinical Trials Registration. NCT00090285.

Abstract
BACKGROUND High-risk (HR) Human Papillomavirus (HPV) has been shown to play an important role in men in various locations in Turkey. This study aims to screen the male persistent infection with the high-risk human papillomavirus (HPV) genotype status in Turkey to provide a reference basis for formulating prevention strategies for the development of genitourinary tract neoplasia. METHODS The HPV QUANT-21 Quantitative RT-PCR Kit® was used to identify and quantify low-risk HPV (HPV 6, 11, 44) and high-risk (HPV 16, 18, 26, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 68, 73, 82) from male individuals in Turkey. RESULTS Of the total 1304 samples, 473 were positive for at least one HPV genotype, with an overall frequency of 36.2%. Two-hundred fifty-four patients were positive only for one or more LR HPV genotypes (54%), and 219 patients were positive for one or more HR HPV genotypes (46%). The LR HPV genotype frequency was 53.7%, while the HR HPV genotype frequency was 46.3%. Our technology had the positive advantage of being able to calculate concentrations for each genotype. Genotype 51 was second in frequency but had the highest average concentration of 5.38 log (copies/sample). CONCLUSION The presence and genotype of the virus before HPV vaccination are also of increasing importance. The data obtained will serve as a guide for prevention strategies, especially vaccination. Based on our findings there is a need of new estimates of the efficacy of currently available HPV vaccines and to develop a screening program to prevent and reduce the incidence of genitourinary tract neoplasias in Turkey. Further studies are planned to measure and define the high levels of infection that may lead to the development of cervical tumors. Using this technique, it may be possible to make clinical decisions about the extent of cytological alterations.

Abstract
BACKGROUND AND OBJECTIVES The 9-valent human papillomavirus (9vHPV) vaccine Phase III immunogenicity study in 9- to 15-year-old boys and girls was extended to assess immunogenicity and effectiveness through 10 years after the last vaccine dose (NCT00943722). METHODS Boys (n = 301) and girls (n = 971) who received three 9vHPV vaccine doses in the base study (day 1, months 2 and 6) enrolled in the extension. Serum was collected through month 126 for antibody assessments by competitive Luminex immunoassay and immunoglobulin G-Luminex immunoassay. For effectiveness analysis starting at age 16 years, genital swabs were collected (to assess HPV DNA by polymerase chain reaction) and external genital examinations conducted every 6 months. Primary analyses were conducted in per-protocol populations. RESULTS Geometric mean antibody titers peaked around month 7, decreased sharply between months 7 and 12, then gradually through month 126. Seropositivity rates remained ≥81% by competitive Luminex immunoassay and ≥95% by immunoglobin G-Luminex immunoassay at month 126 for each 9vHPV vaccine type. After up to 11.0 (median 10.0) years of follow-up postdose 3, there were no cases of HPV6/11/16/18/31/33/45/52/58-related high-grade intraepithelial neoplasia or condyloma in males or females. Incidence rates of HPV6/11/16/18/31/33/45/52/58-related 6-month persistent infection in males and females were low (54.6 and 52.4 per 10000 person-years, respectively) and within ranges expected in vaccinated cohorts, based on previous human papillomavirus vaccine efficacy trials. CONCLUSIONS The 9vHPV vaccine demonstrated sustained immunogenicity and effectiveness through ∼10 years post 3 doses of 9vHPV vaccination of boys and girls aged 9 to 15 years.

Abstract
High-risk human papillomavirus (HPV) infection is the most common cause of cervical cancer, but low-risk HPV strains can sometimes also be involved. Although HPV genotyping techniques used in clinical diagnosis cannot detect low-risk HPV, next-generation sequencing (NGS) can detect both types. However, DNA library preparation is complicated and expensive. The aim of this study was to develop a simplified, cost-effective sample preparation procedure for HPV genotyping based on next-generation sequencing (NGS). After DNA extraction, a first round of PCR was performed using modified MY09/11 primers specific for the L1 region of the HPV genome, followed by a second round of PCR to add the indexes and adaptors. Then, the DNA libraries were purified and quantified, and high-throughput sequencing was performed using an Illumina MiSeq platform. The sequencing reads were compared with reference sequences for HPV genotyping. The limit of detection for HPV amplification was 100 copies/µl. Analysis of the correlation of pathological cytology with the HPV genotype in individual clinical samples showed that HPV66 was the most common genotype found in the normal stage, whereas HPV16 was the main genotype found in low-grade squamous intraepithelial lesions, high-grade squamous intraepithelial lesions, and cervical cancer. This NGS method can detect and identify several HPV genotypes with 92% accuracy and 100% reproducibility, and it shows potential as a simplified and cost-effective technique for large-scale HPV genotyping in clinical samples.

Abstract
The SPF10-polymerase chain reaction (PCR)-based line probe assay (LiPA-25) with high analytical sensitivity and specificity for human papillomavirus (HPV) genotyping in clinical samples has been widely used in vaccine and epidemiologic studies. A real-time multiplex PCR assay using type-specific primers (Hybribio-23) with low workload and cost has been developed recently. The study aimed to compare the performance of LiPA-25 and Hybribio-23 in selected 1731 cervical swab and 117 tissue samples, with a focus on 20 common HPV types (14 high-risk: 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68/73; 6 low-risk: 6, 11, 42, 43, 44, and 53). The level of agreement of two assays was determined using Cohen's Kappa (κ) statistics. A total of 1296 (74.9%) swab samples were identified as HPV-positive by Hybribio-23 or LiPA-25, of which 814 (62.8%) samples exhibited concordant, 358 (27.6%) showed additional or fewer types (compatible), and 124 (9.6%) were discordant. In addition, the two assays showed a perfect agreement for 20 HPV-combined detection (κ = 0.838) and 17 individual HPV types (all κ > 0.800), a good agreement for HPV31 (κ = 0.792) and 43 (κ = 0.696), and a moderate agreement for HPV42 (κ = 0.504). Hybribio-23 was significantly more sensitive for HPV58, 59, 68/73, 42, 43, and 44, and less sensitive for HPV35 and 66 than LiPA-25 (McNemar's test: all p < 0.05). For 117 HPV-positive tissue specimens, the identification of genotypes was 85.2% identical, 12.2% compatible, and only 2.6% discordant. The agreement for HPV31 (κ = 0.786), 68/73 (κ = 0.742), and HPV53 (κ = 0.742) was good, while for other types (all κ > 0.853) and 20 HPV-combined detection (κ = 0.936) was perfect (all p > 0.05). In conclusion, Hybribio-23 and LiPA-25 are comparable. Hybribio-23 could be used for the detection and genotyping of HPV in cervical samples for epidemiological and vaccine studies worldwide.

Abstract
The SPF10-PCR-based line probe assay (LiPA-25) for human papillomavirus (HPV) genotyping with high analytical sensitivity and specificity was widely used in HPV vaccine clinical trials and epidemiologic studies. In the study, we aimed to compare a novel GP5+/6+-PCR-based reverse dot blot hybridization assay (Yaneng-23) with LiPA-25. The performance of two assays was evaluated in 1735 cervical swab and 117 tissue samples, with a focus on 19 common HPV types (14 high-risk: 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68/73; 5 low-risk: 6, 11, 42, 43, and 53). A total of 1197 (69.0%) swab samples were identified as HPV-positive by two assays. Of these, 878 (73.4%) samples displayed absolute agreement (concordant), 255 (21.3%) showed additional or fewer types (compatible), and the remaining 64 (5.3%) samples were discordant. Additionally, the two assays showed an excellent strength of agreement for 19 HPV-combined detection (κ = 0.886) and 17 individual HPV types (all κ > 0.800), and displayed a good agreement for HPV39 (κ = 0.780) and 42 (κ = 0.699). Yaneng-23 was more sensitive than LiPA-25 for HPV58, 59, 68/73, 42, 43 and 53 (McNemar's test: all p < 0.05), while LiPA-25 was more sensitive for HPV31, 39, 52, and 66 than Yaneng-23 (all p < 0.05). In 113 HPV-positive tissue specimens, the identification of genotypes was 82.3% identical and 17.7% compatible. The agreement between the tests for HPV45 (κ = 0.796) and 51 (κ = 0.742) was good, and for other types (all κ > 0.843) and 19 HPV-combined detection (κ = 0.929) was perfect (all p > 0.05). In conclusion, Yaneng-23 and LiPA-25 are comparable. Yaneng-23 could be used for the detection and genotyping of HPV in cervical samples for epidemiological and vaccine studies worldwide.

[PMID: 39036447 PMCID: PMC11256530 DOI: 10.1016/j.jncc.2022.06.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Revised: 06/02/2022] [Accepted: 06/27/2022] [Indexed: 11/20/2022] Open
Abstract
Background The SPF10 LiPA-25 system for human papillomavirus (HPV) detection with high analytical performance is widely used in HPV vaccine clinical trials. To develop and evaluate more valent HPV vaccines, other comparable methods with simpler operations are needed. Methods The performance of the LiPA-25 against that of other 7 assays, including 4 systems based on reverse hybridization (Bohui-24, Yaneng-23, Tellgen-27, and Hybribio-16) and 3 real-time polymerase chain reaction (PCR) assays (Hybribio-23, Bioperfectus-21, and Sansure-26), was evaluated in selected 1726 cervical swab and 56 biopsy samples. A total of 15 HPV genotypes (HPV 6, 11, 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 66) were considered for comparison for each HPV type. Results Among the swab samples, compared to LiPA-25, compatible genotypes were observed in 94.1% of samples for Hybribio-23, 92.8% for Yaneng-23, 92.6% for Bioperfectus-21, 92.4% for Hybribio-16, 91.3% for Sansure-26, 89.7% for Bohui-24, and 88.0% for Tellgen-27. The highest overall agreement of the 15 HPV genotypes combined was noted for Hybribio-23 (κ = 0.879, McNemar's test: P = 0.136), followed closely by Hybribio-16 (κ = 0.877, P< 0.001), Yaneng-23 (κ = 0.871, P < 0.001), Bioperfectus-21 (κ = 0.848, P < 0.001), Bohui-24 (κ = 0.847, P < 0.001), Tellgen-27 (κ = 0.831, P < 0.001), and Sansure-26 (κ = 0.826, P < 0.001). Additionally, these systems were also highly consistent with LiPA-25 for biopsy specimens (all, κ > 0.897). Conclusions The levels of agreement for the detection of 15 HPV types between other 7 assays and LiPA-25 were all good, and Hybribio-23 was most comparable to LiPA-25. The testing operation of HPV genotyping should also be considered for vaccine and epidemiological studies.

Abstract
Developing rapid and inexpensive diagnostic tools for molecular detection has been pushed forward by the advancements of technical aspects. However, attention has rarely been paid to the molecular detection methodology using inkjet printing technique. Herein, we developed an approach that employed a self-assembled inkjet printer as the enabling technology to realize droplet digital loop-mediated isothermal amplification in a low-cost and practical format. An inkjet printer is a self-assembled tool for the generation of discrete droplets in controllable volumes from a picoliter to a nanoliter. A microfluidic chip serves as a droplets reservoir to perform droplet digital LAMP assays. The inkjet printer approach successfully quantified the HPV16 from CaSki cells. This self-assembled and practical inkjet printer device may therefore become a promising tool for rapid molecular detection and can be extended to on-site analysis.

Clin Infect Dis 2022; 74:1247-1256. [PMID: 34265048 DOI: 10.1093/cid/ciab603] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2021] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND In men, the incidence of human papillomavirus (HPV)-related cancer is rising, but data regarding male HPV infection and seroprevalence are available from only a few countries. METHODS This analysis of a global HPV vaccine trial evaluated baseline data from 1399 human immunodeficiency virus-negative heterosexual men (HM) and men who have sex with men (MSM). Key objectives included assessment of HPV prevalence and risk factors for seropositivity to 9-valent HPV (9vHPV) vaccine types (6, 11, 16, 18, 31, 33, 45, 52, and 58), and concordance between seropositivity and prevalent HPV type. RESULTS Overall, 455 of 3463 HM (13.1%) and 228 of 602 MSM (37.9%) were HPV DNA positive for any 9vHPV vaccine type at baseline. Infection prevalence and seroprevalence (≥1 9vHPV vaccine type) were 13.2% and 8.1%, respectively, among 333 HM from Europe, and 37.9% and 29.9%, respectively, among 335 MSM from Europe or North America. Among men with baseline infection, MSM had higher seroprevalence for concordant HPV types (39.5% vs 10.8% in HM). The seropositivity risk (irrespective of baseline infection status) was higher among MSM versus HM (age-adjusted odds ratio, 3.0 [95% confidence interval, 2.4-6.4]). Among MSM, statistically significant seropositivity risk factors included younger age at sexual debut, higher number of receptive anal sex partners, and less frequent condom use. No factors assessed were associated with seropositivity in HM. CONCLUSIONS Higher proportions of MSM than HM were HPV DNA positive and seropositive, and concordance between HPV DNA positivity and seropositivity, a potential marker of true infection versus carriage, was higher in MSM. Most MSM and HM were seronegative for all 9vHPV vaccine types, suggesting the potential benefit of catch-up vaccination after sexual debut.Clinical Trials Registration. NCT00090285.

INFECTIOUS DISEASES 2021; 22:413-425. [PMID: 34780705 DOI: 10.1016/s1473-3099(21)00327-3] [Citation(s) in RCA: 43] [Impact Index Per Article: 14.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/13/2020] [Revised: 04/02/2021] [Accepted: 05/25/2021] [Indexed: 11/15/2022]
Abstract
BACKGROUND The quadrivalent human papillomavirus (HPV) vaccine was shown to prevent infections and lesions related to HPV6, 11, 16, and 18 in a randomised, placebo-controlled study in men aged 16-26 years. We assessed the incidences of external genital warts related to HPV6 or 11, and external genital lesions and anal dysplasia related to HPV6, 11, 16, or 18, over 10 years of follow-up. METHODS The 3-year base study was an international, multicentre, double-blind, randomised, placebo-controlled trial done at 71 sites in 18 countries. Eligible participants were heterosexual men (aged 16-23 years) or men who have sex with men (MSM; aged 16-26 years). Men who had clinically detectable anogenital warts or genital lesions at screening that were suggestive of infection with non-HPV sexually transmitted diseases, or who had a history of such findings, were excluded. Eligible participants were randomly assigned (1:1) to receive three doses of either quadrivalent HPV vaccine or placebo on day 1, month 2, and month 6, administered as a 0·5-mL injection into the deltoid muscle. The 7-year, open-label, long-term follow-up extension study was done at 46 centres in 16 countries. Participants who received one or more doses of the quadrivalent HPV vaccine in the base study were eligible for enrolment into the long-term follow-up study (early vaccination group). Placebo recipients were offered the three-dose quadrivalent HPV vaccine at the end of the base study; those who received one or more quadrivalent HPV vaccine doses were eligible for enrolment into the long-term follow-up study (catch-up vaccination group). The primary efficacy endpoints were the incidence of external genital warts related to HPV6 or 11 and the incidence of external genital lesions related to HPV6, 11, 16, or 18 in all participants and the incidence of anal intraepithelial neoplasia (including anal warts and flat lesions) or anal cancer related to HPV6, 11, 16, or 18 in MSM only. The primary efficacy analysis was done in the per-protocol population for the early vaccination group, which included participants who received all three vaccine doses, were seronegative at day 1 and PCR-negative from day 1 through month 7 of the base study for the HPV type being analysed, had no protocol violations that could affect evaluation of vaccine efficacy, and had attended at least one visit during the long-term follow-up study. For the catch-up vaccination group, efficacy was assessed in the modified intention-to-treat population, which included participants who had received at least one vaccine dose, were seronegative and PCR-negative for HPV types analysed from day 1 of the base study to the final follow-up visit before receiving the quadrivalent HPV vaccine, and had at least one long-term follow-up visit. Safety was assessed in all randomised participants who received at least one vaccine dose. This study is registered with ClinicalTrials.gov, NCT00090285. FINDINGS Between Aug 10, 2010, and April 3, 2017, 1803 participants were enrolled in the long-term follow-up study, of whom 936 (827 heterosexual men and 109 MSM) were included in the early vaccination group and 867 (739 heterosexual men and 128 MSM) were included in the catch-up vaccination group. Participants in the early vaccination group were followed up for a median of 9·5 years (range 0·1-11·5) after receiving the third dose of the quadrivalent HPV vaccine, and participants in the catch-up vaccination group were followed up for a median of 4·7 years (0·0-6·6) after receiving the third dose. In early vaccine group participants during long-term follow-up compared with the placebo group in the base study, the incidence per 10 000 person-years of external genital warts related to HPV6 or 11 was 0·0 (95% CI 0·0-8·7) versus 137·3 (83·9-212·1), of external genital lesions related to HPV6, 11, 16, or 18 was 0·0 (0·0-7·7) versus 140·4 (89·0-210·7), and of anal intraepithelial neoplasia or anal cancer related to HPV6, 11, 16, or 18 in MSM only was 20·5 (0·5-114·4) versus 906·2 (553·5-1399·5). Compared with during the base study (ie, before quadrivalent HPV vaccine administration), during the long-term follow-up period, participants in the catch-up vaccination group had no new reported cases of external genital warts related to HPV6 or 11 (149·6 cases per 10 000 person-years [95% CI 101·6-212·3] vs 0 cases per 10 000 person-years [0·0-13·5]) or external genital lesions related to HPV6, 11, 16, or 18 (155·1 cases per 10 000 person-years [108·0-215·7] vs 0 cases per 10 000 person-years [0·0-10·2]), and a lower incidence of anal intraepithelial neoplasia or anal cancer related to HPV6, 11, 16, or 18 (886·0 cases per 10 000 person-years [583·9-1289·1] vs 101·3 cases per 10 000 person-years [32·9-236·3]). No vaccine-related serious adverse events were reported. INTERPRETATION The quadrivalent HPV vaccine provides durable protection against anogenital disease related to HPV6, 11, 16, and 18. The results support quadrivalent HPV vaccination in men, including catch-up vaccination. FUNDING Merck Sharp & Dohme.

Design of a Phase III efficacy, immunogenicity, and safety study of 9-valent human papillomavirus vaccine in prevention of oral persistent infection in men. Contemp Clin Trials 2021; 115:106592. [PMID: 34678491 DOI: 10.1016/j.cct.2021.106592] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 09/01/2021] [Accepted: 10/05/2021] [Indexed: 12/26/2022]
Abstract
BACKGROUND Seven high-risk human papillomavirus (HPV) types (16/18/31/33/45/52/58) covered by the 9-valent HPV (9vHPV) vaccine cause >90% of HPV-related head and neck cancers (HNCs). An ongoing clinical trial (NCT04199689) was designed to evaluate 9vHPV vaccine efficacy against HPV oral persistent infection, a surrogate endpoint for HPV-related HNCs. METHODS In this double-blind, placebo-controlled, international trial, men aged 20-45 years (N = 6000) are randomized 1:1 to receive 9vHPV vaccine or placebo on day 1, month 2, and month 6. The primary objective is to demonstrate whether 9vHPV vaccination reduces incidence of HPV16/18/31/33/45/52/58-related 6-month oral persistent infection. Incidence of HPV6/11-related 6-month oral persistent infection will be evaluated as a secondary endpoint. Oral rinse and gargle samples will be collected on day 1, month 7, month 12, and every 6 months thereafter for HPV detection by PCR. Primary analyses will be performed in per-protocol populations. Efficacy in this case-driven study will be analyzed upon accrual of ≥20 primary efficacy endpoint cases. Serum will be collected at day 1 and months 7, 12, 24, 36, and 42; anti-HPV antibody titers will be measured by competitive Luminex immunoassay. Data will be summarized as geometric mean titers and seropositivity rates. Injection-site and systemic adverse events (AEs) will be collected for 15 days post-any vaccination and serious AEs through 6 months after the last vaccination; deaths and vaccine-related serious AEs will be collected throughout the study. DISCUSSION This trial is expected to generate important data regarding the potential for 9vHPV vaccine to prevent HPV-related head and neck disease.

Ther Adv Med Oncol 2021; 13:17588359211010939. [PMID: 33995595 PMCID: PMC8107662 DOI: 10.1177/17588359211010939] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2020] [Accepted: 03/25/2021] [Indexed: 12/27/2022] Open
Abstract
Background: China’s Fujian Cervical Pilot Project (FCPP) transitioned cervical cancer screening from high-risk human papillomavirus (HR-HPV) nongenotyping to genotyping. We investigated the clinical impact of this introduction, comparing performance indicators between HR-HPV genotyping combined with cytology screening (HR-HPV genotyping period) and the previous HR-HPV nongenotyping combined with cytology screening (HR-HPV nongenotyping period). Methods: A retrospective population-based cohort study was performed using data from the FCPP for China. We obtained data for the HR-HPV nongenotyping period from 1 January 2012 to 31 December 2013, and for the HR-HPV genotyping period from 1 January 2014 to 31 December 2016. Propensity score matching was used to match women from the two periods. Multivariable Cox regression was used to assess factors associated with cervical intraepithelial neoplasia of grade 2 or worse (CIN2+). The primary outcome was the incidence of CIN2+ in women aged ⩾25 years. Performance was assessed and included consistency, reach, effectiveness, adoption, implementation and cost. Results: Compared with HR-HPV nongenotyping period, in the HR-HPV genotyping period, more CIN2+ cases were identified at the initial screening (3.06% versus 2.32%; p < 0.001); the rate of colposcopy referral was higher (10.87% versus 6.64%; p < 0.001); and the hazard ratio of CIN2+ diagnosis was 1.64 (95% confidence interval, 1.43–1.88; p < 0.001) after controlling for health insurance status and age. The total costs of the first round of screening (US$66,609 versus US$65,226; p = 0.293) were similar during the two periods. Higher screening coverage (25.95% versus 25.19%; p = 0.007), higher compliance with age recommendations (92.70% versus 91.69%; p = 0.001), lower over-screening (4.92% versus 10.15%; p < 0.001), and reduced unqualified samples (cytology: 1.48% versus 1.73%, p = 0.099; HR-HPV: 0.57% versus 1.34%, p < 0.001) were observed in the HR-HPV genotyping period. Conclusions: Introduction of an HR-HPV genotyping assay in China could detect more CIN2+ lesions at earlier stages and improve programmatic indicators. Evidence suggests that the introduction of HR-HPV genotyping is likely to accelerate the elimination of cervical cancer in China.

Abstract
A long-term follow-up (LTFU) of the nine-valent human papillomavirus (9vHPV) vaccine efficacy study in young women aged 16–26 years was initiated to evaluate if vaccine effectiveness for up to 14 years post-vaccination will remain above 90%. Vaccine effectiveness is measured as percent reduction in the incidence of HPV16/18/31/33/45/52/58-related high-grade cervical dysplasia in the LTFU cohort relative to expected incidence in a similar unvaccinated cohort. We report an interim analysis 8 years post-vaccination. Overall, 2029 participants from Denmark, Norway, and Sweden who received the 9vHPV vaccine during the clinical efficacy study continued into the LTFU study. National health registries were used to identify screening attendance and cervical pre-cancer/cancer diagnoses. Tissue samples were retrieved for HPV testing by PCR and pathology diagnosis adjudication. A control chart method was used to detect signals indicative of vaccine effectiveness waning below 90%. No new cases of HPV16/18/31/33/45/52/58-related high-grade cervical dysplasia were observed during the LTFU study period over 4084.2 person-years’ follow-up (per-protocol effectiveness population; n = 1448). Thus, there were no signals indicative of vaccine effectiveness waning below 90%. These observations show that the 9vHPV vaccine provides continued statistically significant protection through at least 6 years, with indications of continued effectiveness through 8 years.

Abstract
OBJECTIVES Human papillomaviruses (HPV) are the main etiology of invasive cervical cancer. Together HPV and viral hepatitis account for the cause of 25% of cancers in developing countries. To evaluate the association between population movements and the spread of HPV, this study looked at prevalence, genotypes, and phylogenetic assessment of HPV in Great Khorasan, a pilgrimage-tourism province in northeast Iran. METHODS From March 2013 to July 2018, 567 samples were collected from three groups in Khorasan: Razavi and North Khorasan provinces (highly mobile population); South Khorasan province (conservative and desert); and diverse group (tourists). RESULTS HPV prevalence was 48.4% in Razavi and North Khorasan (first group); 19.9% in South Khorasan (second group); and 33.6% in the diverse group. The four most common HPV genotypes were HPV-6, 11, 51 and 16, in the first group; HPV-6, 11, 16 and 58 in the second group; and HPV-6, 11, 16 and 53/89 in the diverse group. The most frequent genotypes that are known as high risk for cervical cancer were HPV-51 in the first group, HPV-16 in the second group and the diverse group. Among low-risk genotypes, HPV-6, and HPV-11 were more frequent in all groups. DNA sequencing and phylogenetic analysis of 20 HPV-positive samples showed that the distributions of the HPV genotypes were HPV-6 (50%), 11 (10%), 67 (5%), 16 (15%), 31 (10%), 54 (5%), and 89 (5%). CONCLUSIONS The findings show that areas associated with population movement should be frequently monitored for infectious diseases, while conservative and less populated areas have less risk for virus spread and endemicity. Health authorities should focus more on the establishment of HPV diagnostic facilities, screening, vaccination, and enhancement of public knowledge in these regions.

Long-term immunogenicity, effectiveness, and safety of nine-valent human papillomavirus vaccine in girls and boys 9 to 15 years of age: Interim analysis after 8 years of follow-up. PAPILLOMAVIRUS RESEARCH (AMSTERDAM, NETHERLANDS) 2020; 10:100203. [PMID: 32659510 PMCID: PMC7396911 DOI: 10.1016/j.pvr.2020.100203] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/19/2020] [Revised: 07/07/2020] [Accepted: 07/08/2020] [Indexed: 12/15/2022]
Abstract
BACKGROUND The nine-valent human papillomavirus (9vHPV) vaccine protects against infection and disease related to HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58. The pivotal 36-month Phase III immunogenicity study of 9vHPV vaccine in 9- to 15-year-old girls and boys was extended to assess long-term immunogenicity and effectiveness through approximately 10 years after vaccination. We describe results of an interim analysis based on approximately 8 years of follow-up after vaccination. METHODS Participants aged 9-15 years who received three doses of 9vHPV vaccine (at day 1, month 2, and month 6) in the base study and consented to follow-up were enrolled in the long-term follow-up study extension (N = 1272 [females, n = 971; males, n = 301]). Serum was collected at months 66 and 90 to assess antibody responses. For effectiveness analysis, genital swabs were collected (to assess HPV DNA by polymerase chain reaction [PCR]) and external genital examination was conducted (to detect external genital lesions) every 6 months starting when the participant reached 16 years of age. Cervical cytology tests were conducted annually when female participants reached 21 years of age; participants with cytological abnormalities were triaged to colposcopy based on a protocol-specified algorithm. External genital and cervical biopsies of abnormal lesions were performed, and histological diagnoses were adjudicated by a pathology panel. Specimens were tested by PCR to detect HPV DNA. RESULTS Geometric mean titers for each 9vHPV vaccine HPV type peaked around month 7 and gradually decreased through month 90. Seropositivity rates remained >90% through month 90 for each of the 9vHPV vaccine types by HPV immunoglobulin Luminex Immunoassay. No cases of HPV6/11/16/18/31/33/45/52/58-related high-grade intraepithelial neoplasia or genital warts were observed in the per-protocol population (n = 1107) based on a maximum follow-up of 8.2 years (median 7.6 years) post-Dose 3. Incidence rates of HPV6/11/16/18/31/33/45/52/58-related 6-month persistent infection in females and males were 49.2 and 37.3 per 10,000 person-years, respectively, which were within ranges expected in vaccinated cohorts. There were no vaccine-related SAEs or deaths during the period covered by this interim analysis. CONCLUSIONS The 9vHPV vaccine provided sustained immunogenicity and durable effectiveness through approximately 7 and 8 years, respectively, following vaccination of girls and boys aged 9-15 years.

Abstract
Background This study aims to screen the male human papillomavirus (HPV) infection status and genotyping in Qingcheng District, Qingyuan City, Guangdong Province, China to provide a reference basis for formulating prevention strategies for HPV infection. Methods The present study collected urethral epithelium or scraped penile epidermis from high-risk male patients in Qingyuan People's Hospital during the last five years, extracted DNA fragments using the boiling method, and detected 23 types of HPV genotypes by PCR-reverse blot hybridization. Results The positive detection rate was 54.31% of 1044 males with high risk of HPV (567/1044). Among these males, the positive detection rate of HPV was the highest in patients initially diagnosed with warts, and the rate was 66.47%. Five main HPV types are identified as follows: HPV6 18.87% (197/1044), HPV11 10.25% (107/1044), HPV52 8.81% (92/1044), HPV16 6.90% (72/1044), and HPV51 5.08% (53/1044). Among these HPV-infected patients, single infection mainly by low-risk HPV6 and HPV11 accounted for 56.61% (321/567); high- and low-risk combined HPV co-infections accounted for 29.10% (165/567). The HPV infected patients was mainly between 21 and 40 years old, and the HPV infection rate was higher with increased age. Conclusions The HPV infection rate in the Qingyuan area is higher than in other areas and the main infection is single infection. Furthermore, HPV52, HPV16, and HPV51 are the main high-risk infection types, while HPV6 and HPV11 are the main low-risk infection types.

Abstract
BACKGROUND The quadrivalent human papillomavirus (qHPV) vaccine prevented vaccine HPV type-related infection and disease in young women in the 4-year FUTURE II efficacy study (NCT00092534). We report long-term effectiveness and immunogenicity at the end of 14 years of follow-up after enrollment in FUTURE II. METHODS Young women (16-23 years of age) from Denmark, Iceland, Norway, and Sweden who received three qHPV vaccine doses during the randomized, double-blind, placebo-controlled FUTURE II base study were followed for effectiveness for an additional ≥10 years through national registries. Tissue samples including but not limited to those collected during organized cervical cancer screening programs were obtained from regional biobanks to be adjudicated for histopathology diagnosis and tested for HPV DNA. The observed incidence of HPV16/18-related high-grade cervical dysplasia (primary outcome) was compared with recent historical background incidence rates in an unvaccinated population. Serum was collected at years 9 and 14 to assess antibody responses. FINDINGS No cases of HPV16/18-related high-grade cervical dysplasia were observed in the per-protocol effectiveness population (N = 2121; 24,099·0 person-years of follow-up) during the entire study. Vaccine effectiveness of 100% (95% CI 94·7-100) was demonstrated for ≥12 years, with a trend toward continued protection through 14 years post-vaccination. Seropositivity rates at study conclusion were >90% (HPV6/11/16) and 52% (HPV18) using competitive Luminex immunoassay, and >90% (all four HPV types) using the more sensitive IgG Luminex immunoassay. INTERPRETATION Vaccination of young women with qHPV vaccine offers durable protection against HPV16/18-related high-grade cervical dysplasia for ≥12 years, with a trend toward continued protection through 14 years post-vaccination, and induces sustained HPV6/11/16/18 antibody responses for up to 14 years post-vaccination. There was no evidence of waning immunity, suggesting no need for a booster dose during that period. FUNDING Merck Sharp & Dohme Corp., a subsidiary of Merck & Co., Inc., Kenilworth, NJ, USA.

Identification by high-throughput sequencing of HPV variants and quasispecies that are untypeable by linear reverse blotting assay in cervical specimens. PAPILLOMAVIRUS RESEARCH (AMSTERDAM, NETHERLANDS) 2019; 8:100169. [PMID: 31283993 PMCID: PMC6620621 DOI: 10.1016/j.pvr.2019.100169] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/26/2019] [Revised: 05/11/2019] [Accepted: 06/03/2019] [Indexed: 11/17/2022]
Abstract
The linear reverse blotting assays are valid methods for accurate human papillomavirus (HPV) typing required to manage women at risk of developing cervical cancer. However, some samples showed a positive signal in HPV lines but failed to display a positive signal in subsequent typing lines (designated as HPV-X), which indicate that certain types were not available on the respective typing blots. The aim of this study is to elucidate the types or variants of HPV through the high-throughput sequencing (HTS) of 54 ASCUS cervical samples in which the viruses remained untypeable with INNO LiPA HPV® assays. Low-risk (LR)-HPV types (HPV6, 30, 42, 62, 67, 72, 74, 81, 83, 84, 87, 89, 90 and 114), high-risk (HR)-HPV35 and possibly (p)HR-HPV73 were detected among HPV-X. Individual multiple infections (two to seven types) were detected in 40.7% of samples. Twenty-two specimens contained variants characterised by 2-10 changes. HPV30 reached the maximal number of 17 variants with relative abundance inferior or equal to 2.7%. The presence of L1 quasispecies explains why linear reverse blotting assays fail when variants compete or do not match the specific probes. Further studies are needed to measure the LR-HPV quasispecies dynamics and its role during persistent infection.

Abstract
OBJECTIVE To estimate the proportion of vulvar and vaginal low-grade and high-grade squamous intraepithelial lesions (LSILs and HSILs) in females 15-26 years of age attributable to 14 human papillomavirus (HPV) genotypes (6, 11, 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59). METHODS A post hoc analysis of prospectively diagnosed vulvar and vaginal LSILs and HSILs among females 15-26 years of age enrolled in the placebo arms of two phase 3, randomized HPV vaccine trials assessed 14 prespecified HPV genotypes associated with cervical cancers or anogenital warts using a type-specific multiplex polymerase chain reaction assay. The frequency of lesions associated with specific HPV genotypes was estimated by proportional and other attribution methods. RESULTS During approximately 4 years of follow-up in 8,798 females, 40 vulvar LSILs and 46 vulvar HSILs were diagnosed in 68 females, and 118 vaginal LSILs and 33 vaginal HSILs were diagnosed in 107 females. Females developing vulvar (41.2%) or vaginal (49.5%) lesions also had cervical lesions, whereas 6.5% of females with cervical lesions had vaginal or vulvar lesions. At least 1 of the 14 HPV genotypes was detected in females with vulvar LSIL (72.5%), vulvar HSIL (91.3%), vaginal LSIL (61.9%), and vaginal HSIL (72.7%). Considering only HPV-positive lesions, the nine most common genotypes causing cervical cancer and anogenital warts (6, 11, 16, 18, 31, 33, 45, 52, and 58) were found in 89.4% of vulvar LSILs, 100% of vulvar HSILs, 56.0% of vaginal LSILs, and 78.3% of vaginal HSILs. CONCLUSION Most vulvar and vaginal lesions were attributable to at least 1 of the 14 HPV genotypes analyzed. Effective immunization programs could potentially prevent substantial numbers of HPV-related vulvar and vaginal LSILs and HSILs.

Abstract
Background A 9-valent human papillomavirus-6/11/16/18/31/33/45/52/58 (9vHPV) vaccine extends coverage to 5 next most common oncogenic types (31/33/45/52/58) in cervical cancer versus quadrivalent HPV (qHPV) vaccine. We describe efficacy, immunogenicity, and safety in Asian participants (India, Hong Kong, South Korea, Japan, Taiwan, and Thailand) from 2 international studies: a randomized, double-blinded, qHPV vaccine-controlled efficacy study (young women aged 16–26 years; NCT00543543; Study 001); and an immunogenicity study (girls and boys aged 9–15 years; NCT00943722; Study 002). Methods Participants (N = 2519) were vaccinated at day 1 and months 2 and 6. Gynecological samples (Study 001 only) and serum were collected for HPV DNA and antibody assessments, respectively. Injection-site and systemic adverse events (AEs) were monitored. Data were analyzed by country and vaccination group. Results 9vHPV vaccine prevented HPV-31/33/45/52/58–related persistent infection with 90.4%–100% efficacy across included countries. At month 7, ≥97.9% of participants seroconverted for each HPV type. Injection-site AEs occurred in 77.7%–83.1% and 81.9%–87.5% of qHPV and 9vHPV vaccine recipients in Study 001, respectively, and 62.4%–85.7% of girls/boys in Study 002; most were mild to moderate. Conclusions The 9vHPV vaccine is efficacious, immunogenic, and well tolerated in Asian participants. Data support 9vHPV vaccination programs in Asia.

Abstract
OBJECTIVE Nine-valent human papillomavirus (9vHPV) vaccine efficacy against disease and cervical surgeries related to all nine vaccine components was assessed compared with a historic placebo population. This was not assessed in the 9vHPV vaccine efficacy trial since the trial was quadrivalent HPV (qHPV) vaccine-controlled, efficacy was measured for the five HPV types covered only by 9vHPV vaccine (HPV31/33/45/52/58), but not the four types covered by both vaccines (HPV6/11/16/18). METHODS Three international, randomized, double-blind studies were conducted using the same methodology. In the 9vHPV vaccine study (NCT00543543), 7106 and 7109 women received 9vHPV or qHPV vaccine, respectively. In the historic qHPV vaccine studies (FUTURE I [NCT00092521] and II [NCT00092534]), 8810 and 8812 women received qHPV vaccine or placebo, respectively, based on the same eligibility criteria. Cervical cytological testing was performed regularly. Biopsy or definitive therapy specimens were assessed for HPV DNA. RESULTS Among women negative for 14 HPV types prior to vaccination, incidence of high-grade cervical disease (9vHPV, n = 2 cases; placebo, n = 141 cases) and cervical surgery (9vHPV, n = 3 cases; placebo, n = 170 cases) related to the nine HPV types was reduced by 98.2% (95% confidence interval [CI], 93.6-99.7) and 97.8% (95% CI, 93.4-99.4), respectively. The 9vHPV vaccine did not prevent disease related to vaccine HPV types detected at baseline, but significantly reduced cervical, vulvar, and vaginal diseases related to other vaccine HPV types. CONCLUSIONS Effective implementation of the 9vHPV vaccine may substantially reduce the burden of HPV-related diseases and related medical procedures.

Abstract
Human papillomavirus (HPV) DNA has been detected in the testis tissue of 6.5% of 185 men with non‐obstructive azoospermia (NOA). Others have suggested that seminal HPV originates from contamination from the genital skin and mucosa. One hundred unselected azoospermic men and 43 normal men undergoing vasectomy were recruited. Testicular biopsies for HPV examination were collected from all the men. Additionally, the normal men undergoing vasectomy delivered a semen sample and had a swab for HPV examination taken from the genital skin before vasectomy. A piece of each Vas deferens obtained during the vasectomy was examined for the presence of HPV. Two of the primarily azoospermic men were shown to have cryptozoospermia. It was not possible to detect HPV in the testis tissue of any of the included 98 azoospermic men or the 43 proven fertile men. In the proven fertile men, HPV DNA was detected in the semen of 15 men (35%), on the genital skin of 28 men (65%), and in the Vas deferens in three cases (7%). In 13 (87%) men with HPV‐positive semen samples, HPV DNA was also detected in the skin swabs, and in 11 men (73%), identical HPV genotypes were found in the two locations.

Abstract
Objective Human papillomavirus (HPV) testing is widely incorporated into cervical cancer screening strategies. Current screening requires pelvic examination for cervical sampling, which may compromise participation. The acceptance could be raised by introducing testing on vaginal swabs. We explored the interchangeability of vaginal swabs and cervical smears for HPV testing, by means of a prospective study conducted in female sex workers (FSWs). Besides, we report on the occurrence of 32 different HPV genotypes in FSW with low-grade squamous intraepithelial lesion (LSIL) or high-grade squamous intraepithelial lesion (HSIL). Methods Paired physician-collected vaginal swabs and cervical smears from 303 FSW were tested for HPV using the Abbott RealTime High-Risk HPV assay. Cervical cytology was examined on cervical smears. In case of HSIL/LSIL cytological classification (n=52), both samples were genotyped using INNO-LiPa HPV Genotyping Extra II. Results The overall prevalence of high-risk (HR)-HPV was 51%. In FSW with HSIL/LSIL cervical cytology, the sensitivity and specificity of vaginal samples for the detection of HR-HPV was 100% and 70% and for probable HR-HPV 100% and 91%. The mean number of genotypes identified in vaginal samples (mean=3.5; 95% confidence interval [CI]=2.8–4.2) was significantly higher than in cervical smear samples (mean=2.6; 95% CI=2.1–3.0) (p=0.001). The most frequently encountered HR-HPV genotypes were HPV16, 31, 51, and 52. Conclusion As our study shows that vaginal swabs are equivalent to cervical smears for the detection of (probable) HR-HPV, vaginal swabs can be used for HPV testing in cervical cancer screening strategies. Given the acceptance of vaginal sampling, this finding offers an opportunity to boost screening coverage.

Abstract
AIMS To determine the value of a monoclonal antibody panel against a C-terminal conserved sequence polypeptide of human papillomavirus (HPV) L1 (a major capsid protein) for the detection of HPV in cervical exfoliated cells, as well as the potential of this antibody panel to be developed into an assay kit for the clinical screening of cervical cancer. METHODS Cervical exfoliated cells were collected at a gynecology clinic. One part of each sample was sent to the Department of Pathology for HPV genotyping, and the other part was sent to the Department of Pathology for cytologic testing and then to the laboratory for immunological histological chemistry (IHC) assay in which an HPV L1 C-terminal conserved sequence polypeptide-induced mouse monoclonal antibody panel was used to detect HPV L1. RESULTS Cervical cell samples were collected from 514 patients at the gynecology clinic; of these, 339 samples were sent for HPV genotyping, and 220 were HPV positive (64.90%, 220/339). Moreover, the duplicate samples from these 339 patients were sent for IHC assay, and 229 samples were positive (67.55%, 229/339). The IHC result was concordant with that obtained by HPV genotyping (Kappa = 0.743, p < 0.001). CONCLUSION This study showed that use of the HPV L1 C-terminal conserved sequence polypeptide-induced mouse monoclonal antibody panel was of great value for the detection of HPV in cervical cells; the resulting detection rate was comparable to that obtained using the commercial HPV genotyping kit that is currently in use in clinical practice.

[PMID: 28886907 DOI: 10.1016/s0140-6736(17)31821-4] [Citation(s) in RCA: 272] [Impact Index Per Article: 38.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2017] [Revised: 06/08/2017] [Accepted: 06/15/2017] [Indexed: 12/16/2022]
Abstract
BACKGROUND Primary analyses of a study in young women aged 16-26 years showed efficacy of the nine-valent human papillomavirus (9vHPV; HPV 6, 11, 16, 18, 31, 33, 45, 52, and 58) vaccine against infections and disease related to HPV 31, 33, 45, 52, and 58, and non-inferior HPV 6, 11, 16, and 18 antibody responses when compared with quadrivalent HPV (qHPV; HPV 6, 11, 16, and 18) vaccine. We aimed to report efficacy of the 9vHPV vaccine for up to 6 years following first administration and antibody responses over 5 years. METHODS We undertook this randomised, double-blind, efficacy, immunogenicity, and safety study of the 9vHPV vaccine study at 105 study sites in 18 countries. Women aged 16-26 years old who were healthy, with no history of abnormal cervical cytology, no previous abnormal cervical biopsy results, and no more than four lifetime sexual partners were randomly assigned (1:1) by central randomisation and block sizes of 2 and 2 to receive three intramuscular injections over 6 months of 9vHPV or qHPV (control) vaccine. All participants, study investigators, and study site personnel, laboratory staff, members of the sponsor's study team, and members of the adjudication pathology panel were masked to vaccination groups. The primary outcomes were incidence of high-grade cervical disease (cervical intraepithelial neoplasia grade 2 or 3, adenocarcinoma in situ, invasive cervical carcinoma), vulvar disease (vulvar intraepithelial neoplasia grade 2/3, vulvar cancer), and vaginal disease (vaginal intraepithelial neoplasia grade 2/3, vaginal cancer) related to HPV 31, 33, 45, 52, and 58 and non-inferiority (excluding a decrease of 1·5 times) of anti-HPV 6, 11, 16, and 18 geometric mean titres (GMT). Tissue samples were adjudicated for histopathology diagnosis and tested for HPV DNA. Serum antibody responses were assessed by competitive Luminex immunoassay. The primary evaluation of efficacy was a superiority analysis in the per-protocol efficacy population, supportive efficacy was analysed in the modified intention-to-treat population, and the primary evaluation of immunogenicity was a non-inferiority analysis. The trial is registered with ClinicalTrials.gov, number NCT00543543. FINDINGS Between Sept 26, 2007, and Dec 18, 2009, we recruited and randomly assigned 14 215 participants to receive 9vHPV (n=7106) or qHPV (n=7109) vaccine. In the per-protocol population, the incidence of high-grade cervical, vulvar and vaginal disease related to HPV 31, 33, 45, 52, and 58 was 0·5 cases per 10 000 person-years in the 9vHPV and 19·0 cases per 10 000 person-years in the qHPV groups, representing 97·4% efficacy (95% CI 85·0-99·9). HPV 6, 11, 16, and 18 GMTs were non-inferior in the 9vHPV versus qHPV group from month 1 to 3 years after vaccination. No clinically meaningful differences in serious adverse events were noted between the study groups. 11 participants died during the study follow-up period (six in the 9vHPV vaccine group and five in the qHPV vaccine group); none of the deaths were considered vaccine-related. INTERPRETATION The 9vHPV vaccine prevents infection, cytological abnormalities, high-grade lesions, and cervical procedures related to HPV 31, 33, 45, 52, and 58. Both the 9vHPV vaccine and qHPV vaccine had a similar immunogenicity profile with respect to HPV 6, 11, 16, and 18. Vaccine efficacy was sustained for up to 6 years. The 9vHPV vaccine could potentially provide broader coverage and prevent 90% of cervical cancer cases worldwide. FUNDING Merck & Co, Inc.

Abstract
INTRODUCTION The 9-valent human papillomavirus (9vHPV) vaccine covers the same HPV types (6/11/16/18) as the quadrivalent HPV (qHPV) vaccine and 5 additional cancer-causing types (31/33/45/52/58). Epidemiological studies indicate that the 9vHPV vaccine could prevent approximately 90% of cervical cancers, 70-85% of high-grade cervical dysplasia (precancers), 85-95% of HPV-related vulvar, vaginal, and anal cancers, and 90% of genital warts. Areas covered: Study design features and key findings from the 9vHPV vaccine clinical development program are reviewed. In particular, 9vHPV vaccine efficacy was established in a Phase III study in young women age 16-26 years. Efficacy results in young women were extrapolated to pre- and young adolescent girls and boys and young men by immunological bridging (i.e., demonstration of non-inferior immunogenicity in these groups versus young women). Expert commentary: The development of the 9vHPV vaccine is the outcome of 20 years of continuous clinical research. Broad vaccination programs could help substantially decrease the incidence of HPV-related disease.

Abstract
Mutations in the BRAF proto-oncogene occur in the majority of cutaneous melanomas. The commonly detected valine (V) to glutamate (E) mutation (V600E) is known to drive melanomagenesis and has thus been the target of two highly selective chemotherapeutic agents: vemurafenib and dabrafenib. While BRAF inhibitor therapy has revolutionized the treatment of metastatic melanoma, unanticipated cutaneous toxicities, including the development of cutaneous squamous cell carcinomas (cSCCs), are frequently reported and hinder therapeutic durability. However, the mechanisms by which BRAF inhibitors induce cutaneous neoplasms are poorly understood, thus posing a challenge for specific therapies. In this review, we summarize the clinical and molecular profiles of BRAF inhibitor-associated cSCCs, with a focus on factors that may contribute to disease pathogenesis. In particular, we discuss the emerging evidence pointing towards viral involvement in BRAF inhibitor-induced cutaneous neoplasms and offer new perspectives on future therapeutic interventions. Continued clinical and mechanistic studies along this line will not only allow for better understanding of the pathogenic progression of BRAF inhibitor-induced cSCCs, but will also lead to development of new therapeutic and preventative options for patients receiving targeted cancer therapy.

Abstract
BACKGROUND The immunogenicity profile of the 9-valent HPV (9vHPV) vaccine was evaluated across five phase III clinical studies conducted in girls and boys 9-15 years of age and young women 16-26 years of age. The effect of baseline characteristics of subjects on vaccine-induced HPV antibody responses was assessed. METHODS Immunogenicity data from 11,304 subjects who received ≥1 dose of 9vHPV vaccine in five Phase III studies were analyzed. Vaccine was administered as a 3-dose regimen. HPV antibody titers were assessed 1 month after dose 3 using a competitive Luminex immunoassay and summarized as geometric mean titers (GMTs). Covariates examined were age, gender, race, region of residence, and HPV serostatus and PCR status at day 1. RESULTS GMTs to all 9 vaccine HPV types decreased with age at vaccination initiation, and were otherwise generally similar among the demographic subgroups defined by gender, race and region of residence. For all subgroups defined by race or region of residence, GMTs were higher in girls and boys than in young women. Vaccination of subjects who were seropositive at day 1 to a vaccine HPV type resulted in higher GMTs to that type, compared with those in subjects who were seronegative for that type at day 1. CONCLUSIONS 9vHPV vaccine immunogenicity was robust among subjects with differing baseline characteristics. It was generally comparable across subjects of different races and from different regions. Greater immunogenicity in girls and boys versus young women (the population used to establish 9vHPV vaccine efficacy in clinical studies) indicates that the anti-HPV responses generated by the vaccine in adolescents from all races or regions were sufficient to induce high-level protective efficacy. This immunogenicity profile supports a widespread 9vHPV vaccination program and early vaccination.

Design of a long-term follow-up effectiveness, immunogenicity and safety study of women who received the 9-valent human papillomavirus vaccine. Contemp Clin Trials 2016; 52:54-61. [PMID: 27777126 DOI: 10.1016/j.cct.2016.10.006] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2016] [Revised: 10/17/2016] [Accepted: 10/18/2016] [Indexed: 10/20/2022]
Abstract
The 9-valent human papillomavirus (HPV) (9vHPV) vaccine targets four HPV types (6/11/16/18) also covered by the quadrivalent HPV (qHPV) vaccine and five additional types (31/33/45/52/58). Vaccine efficacy to prevent HPV infection and disease was established in a Phase III clinical study in women 16-26years of age. A long-term follow-up (LTFU) study has been initiated as an extension of the Phase III clinical study to assess effectiveness of the 9vHPV vaccine up to at least 14years after the start of vaccination. It includes participants from Denmark, Norway and Sweden and uses national health registries from these countries to assess incidence of cervical pre-cancers and cancers due to the 7 oncogenic types in the vaccine (HPV 16/18/31/33/45/52/58). Incidences will be compared to the estimated incidence rate in an unvaccinated cohort of similar age and risk level. This LTFU study uses a unique design: it is an extension of a Phase III clinical study and also has elements of an epidemiological study (i.e., endpoints based on standard clinical practice; surveillance using searches from health registries); it uses a control chart method to determine whether vaccine effectiveness may be waning. Control chart methods which were developed in industrial and manufacturing settings for process and production monitoring, can be used to monitor disease incidence in real-time and promptly detect a decrease in vaccine effectiveness. Experience from this innovative study design may be applicable to other medicinal products when long-term outcomes need to be assessed, there is no control group, or outcomes are rare.

Abstract
The highly programmable positioning of molecules (biomolecules, nanoparticles, nanobeads, nanocomposites materials) on surfaces has potential applications in the fields of biosensors, biomolecular electronics, and nanodevices. However, the conventional techniques including self-assembled monolayers fail to position the molecules on the nanometer scale to produce highly organized monolayers on the surface. The present article elaborates different techniques for the immobilization of the biomolecules on the surface to produce microarrays and their diagnostic applications. The advantages and the drawbacks of various methods are compared. This article also sheds light on the applications of the different technologies for the detection and discrimination of viral/bacterial genotypes and the detection of the biomarkers. A brief survey with 115 references covering the last 10 years on the biological applications of microarrays in various fields is also provided.

Comparing the Cervista HPV HR test and Hybrid Capture 2 assay in a Dutch screening population: improved specificity of the Cervista HPV HR test by changing the cut-off. PLoS One 2014; 9:e101930. [PMID: 25051098 PMCID: PMC4106783 DOI: 10.1371/journal.pone.0101930] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2014] [Accepted: 06/13/2014] [Indexed: 11/24/2022] Open
Abstract
The diagnostic performance of the widely-used Cervista HPV HR test was compared to the Hybrid Capture 2 (HC2) test in a Dutch population-based cervical cancer screening program. In 900 scrapings of women with normal cytomorphology, specificity was 90% (95%CI: 87.84–91.87) for the Cervista HPV HR test and 96% (95%CI: 94.76–97.37) for the HC2 test with 93% agreement between both tests (κ = 0.5, p<0.001). The sensitivity for CIN2+ using 65 scrapings of women with histological-confirmed CIN2+ was 91% (95%CI: 80.97–96.51) for the Cervista HPV HR test and 92% (95%CI: 82.94–97.43) for the HC2 test with 95% agreement between both tests (κ = 0.7, p<0.001). Fifty-seven of 60 HC2 negative/Cervista positive cases tested HPV-negative with PCR-based HPV assays; of these cases 56% were defined as Cervista triple-positive with FOZ values in all 3 mixes higher than the second cut-off of 1.93 (as set by manufacturer). By setting this cut-off at 5.0, specificity improved significantly without affecting sensitivity. External validation of this new cut-off at 5.0 in triple-positive scrapings of women selected from the SHENCCASTII database revealed that 22/24 histological normal cases now tested HPV-negative in the Cervista HPV HR test, while CIN2+ lesions remained HPV-positive. The intra-laboratory reproducibility of the Cervista HPV HR test (n = 510) showed a concordance of 92% and 93% for cut-off 1.93 and 5.0 (κ = 0.83 and κ = 0.84, p<0.001) and inter-laboratory agreement of the Cervista HPV HR test was 90% and 93% for cut-off 1.93 and 5.0 (κ = 0.80 and κ = 0.85, p<0.001). In conclusion, the specificity of the Cervista HPV HR test could be improved significantly by increasing the second cut-off from 1.93 to 5.0, without affecting the sensitivity of the test in a population-based screening setting.

Comparison of the AdvanSure HPV GenoBlot assay with the INNO-LiPA HPV genotyping assay for human papillomavirus genotyping. J Clin Virol 2014; 60:34-8.

Abstract
BACKGROUND Persistent infection with oncogenic human papillomavirus (HPV) genotypes has been shown to be necessary for the development of cervical cancer. The recently developed AdvanSure HPV GenoBlot assay (AdvanSure assay) is based on real-time PCR amplification and reverse line-blot hybridization. OBJECTIVE We first evaluated the performance of the AdvanSure assay compared to the INNO-LiPA HPV Genotyping assay (INNO-LiPA assay) for the molecular genotyping of HPV. STUDY DESIGN A total of 200 cervical swab specimens were genotyped by the AdvanSure and INNO-LiPA assays. The AdvanSure and INNO-LiPA assays can detect 35 and 28 HPV genotypes, respectively. Samples that showed discrepancy were genotyped using sequencing. RESULTS The percent agreement between the two assays ranged from 95.4 to 100% according to genotype. Analyzing the kappa values showed almost perfect agreement (>0.9) for high-risk HPV genotypes 16, 18 and 33 and substantial agreement (0.724) for HPV genotype 31. The positive rates of the two assays for frequent HPV genotypes (16, 18, 31, 33, 53, 58, 66, 68, and 70) were not statistically different, but the INNO-LiPA assay showed higher positive rates than the AdvanSure assay for HPV genotypes 51, 52, and 56 (P<0.05). All HPV genotypes that can be detected by only the AdvanSure assay (HPV genotypes 32, 34, 42, 55, 61, 62, and 81) were confirmed by sequencing. CONCLUSION The AdvanSure assay was comparable with the well-established INNO-LiPA assay. The AdvanSure assay is a new alternative test for HPV genotyping in clinical laboratories.

Abstract
Background Data on the current burden of adenocarcinoma (ADC) and histology-specific human papillomavirus (HPV) type distribution are relevant to predict the future impact of prophylactic HPV vaccines. Methods We estimate the proportion of ADC in invasive cervical cancer, the global number of cases of cervical ADC in 2015, the effect of cervical screening on ADC, the number of ADC cases attributable to high-risk HPV types -16, -18, -45, -31 and -33, and the potential impact of HPV vaccination using a variety of data sources including: GLOBOCAN 2008, Cancer Incidence in Five Continents (CI5) Volume IX, cervical screening data from the World Health Organization/Institut Català d'Oncologia Information Centre on HPV and cervical cancer, and published literature. Results ADC represents 9.4% of all ICC although its contribution varies greatly by country and region. The global crude incidence rate of cervical ADC in 2015 is estimated at 1.6 cases per 100,000 women, and the projected worldwide incidence of ADC in 2015 is 56,805 new cases. Current detection rates for HPV DNA in cervical ADC tend to range around 80–85%; the lower HPV detection rates in cervical ADC versus squamous cell carcinoma may be due to technical artefacts or to misdiagnosis of endometrial carcinoma as cervical ADC. Published data indicate that the five most common HPV types found in cervical ADC are HPV-16 (41.6%), -18 (38.7%), -45 (7.0%), -31 (2.2%) and -33 (2.1%), together comprising 92% of all HPV positive cases. Future projections using 2015 data, assuming 100% vaccine coverage and a true HPV causal relation of 100%, suggest that vaccines providing protection against HPV-16/18 may theoretically prevent 79% of new HPV-related ADC cases (44,702 cases annually) and vaccines additionally providing cross-protection against HPV-31/33/45 may prevent 89% of new HPV-related ADC cases (50,769 cases annually). Conclusions It is predicted that the currently available HPV vaccines will be highly effective in preventing HPV-related cervical ADC.

HPV genotype distribution according to severity of cervical neoplasia using the Digene HPV genotyping LQ test. Arch Virol 2013; 158:1143-9.

Abstract
A new genotyping-based DNA assay (Digene LQ®) was developed recently. The primary aim was to assess the distribution of HPV types using this new assay in atypical squamous cells of undeterminate significance (ASCUS). The secondary aim was to correlate the HPV types with the severity of the disease. The study population comprised 376 ASCUS women. The women were all Hybrid Capture II (HCII) positive and were admitted in three European referral gynecology clinics between 2007 and 2010. A colposcopy with histological examination was performed in all these patients. HPV 16 was typed in 40 % of patients, HPV 18 in 7 %, and HPV 31 in 17 %, and 18 % of patients had mixed genotypes. Patients aged over 30 more often had the HPV 16 genotype than patients aged under 30 (29 % vs. 11 %, chi-square test p < 0.001). The risk of cervical intra-epithelial neoplasia of grade 2 or more (CIN2 +) when HPV 18 positive is lower than the probability associated with HPV 16 or HPV 31: 28 % vs. 58 % and 52 %, respectively (chi-square test, p = 0.005 and p = 0.05, respectively). The Digene LQ®, a new sequence-specific hybrid capture sample preparation, is fast and efficient and allows high-throughput genotyping of 18 HR HPV types by PCR compared to traditional non-sequence-specific sample preparation methods.

Abstract
Medical practitioners in nine countries submitted samples of Gardasil (Merck & Co.) to be tested for the presence of human papillomavirus (HPV) DNA because they suspected that residual recombinant HPV DNA left in the vaccine might have been a contributing factor leading to some of the unexplained post-vaccination side effects. A total of 16 packages of Gardasil were received from Australia, Bulgaria, France, India, New Zealand, Poland, Russia, Spain and the United States. A nested polymerase chain reaction (PCR) method using the MY09/MY11 degenerate primers for initial amplification and the GP5/GP6-based nested PCR primers for the second amplification were used to prepare the template for direct automated cycle DNA sequencing of a hypervariable segment of the HPV L1 gene which is used for manufacturing of the HPV L1 capsid protein by a DNA recombinant technology in vaccine production. Detection of HPV DNA and HPV genotyping of all positive samples were finally validated by BLAST (Basic Local Alignment Search Tool) analysis of a 45-60 bases sequence of the computer-generated electropherogram. The results showed that all 16 Gardasil samples, each with a different lot number, contained fragments of HPV-11 DNA, or HPV-18 DNA, or a DNA fragment mixture from both genotypes. The detected HPV DNA was found to be firmly bound to the insoluble, proteinase-resistant fraction, presumably of amorphous aluminum hydroxyphosphate sulfate (AAHS) nanoparticles used as adjuvant. The clinical significance of these residual HPV DNA fragments bound to a particulate mineral-based adjuvant is uncertain after intramuscular injection, and requires further investigation for vaccination safety.

Abstract
Accurate and internationally comparable human papillomavirus (HPV) DNA genotyping is essential both for evaluation of HPV vaccines and for effective monitoring and implementation of vaccination programs. The World Health Organization (WHO) HPV Laboratory Network (LabNet) regularly issues international proficiency studies. The 2010 HPV genotyping proficiency panel for HPV vaccinology contained 43 coded samples composed of purified plasmids of 16 HPV types (HPV types 6, 11, 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68a and 68b) and 3 coded extraction controls. Proficient typing was defined as detection in both single and multiple infections of 50 international units (IU) of HPV type 16 (HPV-16) and HPV-18 DNA and 500 genome equivalents (GE) for the other 14 HPV types. Ninety-eight laboratories worldwide submitted a total of 132 data sets. Twenty-four different HPV genotyping assay methods were used, with Linear Array being the most commonly used. Other major assays used were a line blot assay (Inno-LiPa), CLART, type-specific real-time PCR, PCR Luminex, and different microarray assays. Altogether, 72 data sets were proficient for detection of more than 1 type, and only 26 data sets proficiently detected all 16 HPV types. The major oncogenic HPV types, 16 and 18, were proficiently detected in 95.0% (114/120) and 87.0% (94/108) of data sets, respectively. Forty-six data sets reported multiple false-positive results and were considered nonproficient. A trend toward increased sensitivity of assays was seen for the 41 laboratories that participated in both 2008 and 2010. In conclusion, continued global proficiency studies will be required for establishing comparable and reliable HPV genotyping services for vaccinology worldwide.

Abstract
INTRODUCTION While high HPV 16 viral load measured at a single time point is associated with cervical disease outcomes, few studies have assessed changes in HPV 16 viral load on viral clearance. OBJECTIVE To measure the association between changes in HPV 16 viral load and viral clearance in a cohort of Thai women infected with HPV 16. STUDY DESIGN Fifty women (n=50) between the ages of 18-35 years enrolled in a prospective cohort study were followed up every three months for two years. Women positive for HPV 16 DNA by multiplex TaqMan assay at two or more study visits were selected for viral load quantitation using a type-specific TaqMan based real-time PCR assay. The strength of the association of change in viral load between two visits and viral clearance at the subsequent visit was assessed using a GEE model for binary outcomes. RESULTS At study entry, HPV 16 viral load did not vary by infection outcome. A >2 log decline in viral load across two study visits was found to be strongly associated with viral clearance (AOR: 5.5, 95% CI: 1.4-21.3). HPV 16 viral load measured at a single time point was not associated with viral clearance. CONCLUSIONS These results demonstrate that repeated measurement of HPV 16 viral load may be a useful predictor in determining the outcome of early endpoints of viral infection.
