Outcome Measures

Primary Outcomes

Incidence of the Composite Endpoint of Human Papillomavirus (HPV) 16/18-related Cervical Intraepithelial Neoplasia (CIN) 2 or Worse in the Base Study

This measure is defined to have occurred when, on a single cervical biopsy, endocervical curettage (ECC), loop electrosurgical excision procedure (LEEP), or conization specimen, there was HPV Vaccine consensus diagnosis of CIN 2 or worse up to 4 years after the first vaccination. For this measure, CIN 2 or worse includes CIN 2, CIN 3, adenocarcinoma in situ (AIS) or cervical cancer related to HPV 16 or 18.

Time frame: Up to 4 years

Incidence of the Composite Endpoint of Human Papillomavirus (HPV) 16/18-related Cervical Intraepithelial Neoplasia (CIN) 2 or Worse in the Long-term Follow-up (LTFU) Study

This measure is defined to have occurred when, on a single cervical biopsy, endocervical curettage (ECC), loop electrosurgical excision procedure (LEEP), or conization specimen, there was HPV Vaccine Nordic pathology panel (NPP) consensus diagnosis of CIN 2 or worse up to 14 years after the first vaccination. For this measure, CIN 2 or worse includes CIN 2, CIN 3, AIS or cervical cancer related to HPV 16 or 18. Only participants who received qHPV vaccine during the Base Study vaccination period and consented for inclusion in the LTFU are included. Because the objective was to demonstrate qHPV vaccine prophylactic efficacy at 14 years, Cohort 2 was not included in the analysis.

Effect of Prior 9-Valent Human Papillomavirus Vaccination on Subsequent Lower Genital Tract Dysplasia After Cervical Excisional Surgery

OBJECTIVE: To assess the efficacy of prior 9-valent human papillomavirus (9vHPV) vaccination on risk of subsequent cervical, vaginal, and vulvar disease after a cervical excisional procedure for cervical squamous intraepithelial lesion (SIL) in a retrospective clinical trial analysis. METHODS: Women aged 16–26 years were randomized to three-dose regimens of 9vHPV vaccine, quadrivalent HPV (4vHPV) vaccine, or placebo in three double-blind efficacy trials: a study of 9vHPV vaccine compared with 4vHPV vaccine (ClinicalTrials.gov, NCT00543543) and two historic placebo-controlled 4vHPV vaccine studies (ClinicalTrials.gov, NCT00092521 and NCT00092534). Incidence of subsequent condyloma, cervical, vulvar, or vaginal SIL was compared between 9vHPV vaccine and controls in women who underwent cervical excisional surgery after vaccination and had 6 months or more of follow-up after surgery. For HPV31/33/45/52/58–related endpoints, the control group was 4vHPV vaccine (from 9vHPV vaccine trial); for HPV6/11/16/18 analysis, the control group was historic placebo (from 4vHPV vaccine trials). RESULTS: This analysis included 295 9vHPV vaccine, 722 4vHPV vaccine, and 493 historic placebo recipients who underwent cervical surgery after a median of 1.7 years (range 0.1–4.4 years) after dose 1. Subsequent to surgery, HPV6/11/16/18–related SIL incidence was reduced by 95.4% (95% CI, 74.7–99.8%) with prior 9vHPV vaccine relative to historic placebo (1.3 vs 29.0/1,000 person-years, respectively); HPV31/33/45/52/58–related SIL incidence was reduced by 86.3% (95% CI, 47.5–97.8%) with 9vHPV vaccine compared with 4vHPV vaccine (2.7 vs 19.4/1,000 person-years, respectively). The incidence of high-grade SIL was numerically lower in the 9vHPV vaccine group relative to control, but this was not statistically significant (HPV6/11/16/18 related 69.6% reduction [95% CI, −133.5% to 98.7%]; HPV31/33/45/52/58 related 82.7% [95% CI, −29.2% to 99.2%]). CONCLUSION: Among female trial participants who underwent cervical excisional surgery, prior vaccination with 9vHPV vaccine (ie, 0.1–4.4 years before surgery) reduced the incidence of subsequent cervical and lower genital tract dysplasia.

Human papillomavirus vaccine efficacy against invasive, HPV-positive cancers: population-based follow-up of a cluster-randomised trial

Background Human papillomavirus (HPV) vaccination protects against HPV, a necessary risk factor for cervical cancer. We now report results from population-based follow-up of randomised cohorts that vaccination provides HPV-type-specific protection against invasive cancer. Methods Individually and/or cluster randomised cohorts of HPV-vaccinated and non-vaccinated women were enrolled in 2002–2005. HPV vaccine cohorts comprised originally 16–17 year-old HPV 16/18-vaccinated PATRICIA (NCT00122681) and 012 trial (NCT00169494) participants (2465) and HPV6/11/16/18-vaccinated FUTURE II (NCT00092534) participants (866). Altogether, 3341 vaccines were followed by the Finnish Cancer Registry in the same way as 16 526 non-HPV-vaccinated controls. The control cohort stemmed from 15 665 originally 18–19 years-old women enrolled in 2003 (6499) or 2005 (9166) and 861 placebo recipients of the FUTURE II trial. The follow-up started 6 months after the clinical trials in 2007 and 2009 and ended in 2019. It was age aligned for the cohorts. Findings During a follow-up time of up to 11 years, we identified 17 HPV-positive invasive cancer cases (14 cervical cancers, 1 vaginal cancer, 1 vulvar cancer and 1 tongue cancer) in the non-HPV-vaccinated cohorts and no cases in the HPV-vaccinated cohorts. HPV typing of diagnostic tumour blocks found HPV16 in nine cervical cancer cases, HPV18, HPV33 and HPV52 each in two cases and HPV45 in one cervical cancer case. The vaginal, vulvar and tongue cancer cases were, respectively, positive for HPV16, HPV52/66 and HPV213. Intention-to-treat vaccine efficacy against all HPV-positive cancers was 100% (95% CI 2 to 100, p<0.05). Interpretation Vaccination is effective against invasive HPV-positive cancer.

Use of real-world data for HPV vaccine trial follow-up in the Nordic region

Post-marketing studies are commonly performed to follow-up on the safety and effectiveness of a drug or vaccine after approval has been obtained. These post-marketing studies may involve the collection of real-world data from registries and clinical biobanks in order to obtain real-world evidence. As this approach can monitor the effects of pharmaceutical products over decades, it is particularly necessary for the development of safe and effective vaccines. A long-term follow-up (LTFU) study was initiated as an extension of a phase 3 clinical study (V501-015; NCT00092534) to assess the effectiveness, immunogenicity and safety of the quadrivalent human papillomavirus (qHPV) vaccine for up to 14 years after the start of vaccination. The LTFU study included participants from Denmark, Iceland, Norway, and Sweden, and assessed qHPV vaccine effectiveness against cervical pre-cancers and cancers caused by the oncogenic HPV types 16 and 18. In particular, our study utilized Nordic national health registries, in which individual patient records were linked by a unique Personal Identity Number. Here, we describe the overall implementation and methodology of the qHPV vaccine LTFU study conducted in the Nordic region. The LTFU study format we describe here supported a comprehensive follow-up process, with near-complete retrieval of registry data and specimens from local laboratories achieved in a timely manner; therefore, we have demonstrated that such a collection is feasible and can be used to address stringent post-marketing requirements.
