Trial Outcomes & Findings for GARDASIL™ Vaccine Impact in Population Study (V501-033) (NCT NCT01077856)

NCT ID: NCT01077856

Last Updated: 2022-09-13

Results Overview

All Nordic countries participating in this study have national cervical cancer screening programs and registry systems that routinely collect information on cervical cytology, histology, and/or definitive therapy results. The collection of such data in these registries is mandated by law and compliance is generally very high. The number of new cases of high-grade (2/3) CIN registered during the assessment periods in Denmark was recorded. Incidence rates are for all age groups and were age-adjusted using the European Standard Population. The incidence before Gardasil licensure is an average over the 3-year period.

Population: The analysis population was the entire population of qualifying women in Denmark and thus changed throughout the analysis. The number of participants analyzed given below is an estimate calculated from the number of reported cases and the incidence data.

PRIMARY outcome

Timeframe: Three years before Gardasil licensure (2004 to 2006) and two years after Gardasil licensure (2011 to 2012)

Population: The analysis population was participants of all ages with newly-diagnosed high-grade CIN and lesional tissue samples analyzed for HPV types

All Nordic countries participating in this study have national cervical cancer screening programs and registry systems that routinely collect information on cervical cytology, histology, and/or definitive therapy results. In addition, lesional tissue samples were routinely collected and stored; the 2004 to 2006 period was chosen because it was sufficiently recent to reflect HPV type status immediately before licensure of Gardasil. The number of new cases of HPV 6/11/16/18-related high-grade (2/3) CIN was estimated based on the proportion of HPV 6/11/16/18 in all CIN in a representative sample. Incidence was age-adjusted according to Nordic Standard Population.

Timeframe: Three years before Gardasil licensure (2004 to 2006) and two years after Gardasil licensure (2011 to 2012)

Population: The analysis population was participants \<=26 years of age with newly-diagnosed high-grade CIN and lesional tissue samples analyzed for HPV types

In addition, lesional tissue samples were routinely collected and stored; the 2004 to 2006 period was chosen because it was sufficiently recent to reflect HPV type status immediately before licensure of Gardasil. The percentage of new cases of high-grade (2/3) CIN related to high-risk HPV types other than 16 and 18 was analyzed. High-risk HPV types include 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68. Incidence was age-adjusted according to Nordic Standard Population.

Population: The analysis population represents the babies born to participating mothers, instead of female participants, because the number of babies represents the denominator for the percentage calculation, not female participants (i.e., mothers)

The percentage of live born babies with major congenital anomalies (MCA) born to women vaccinated with Gardasil during pregnancy and to women in the general population was assessed. For Denmark and Sweden diagnoses of congenital anomaly within 1 year of birth are included; for Norway diagnoses at birth are included.

Population: The analysis population was to be women who underwent cervical screening. A joint decision was made by the study team to forgo the stratified analysis by vaccination status because there were few women who had both been vaccinated with Gardasil and undergone cervical cancer screening. Thus, the number of participants analyzed is zero.

The incidence of CIN by Gardasil vaccination status was to be assessed.

Timeframe: Four years to 5 years after Gardasil licensure (2011 to 2012)

Population: The analysis population was to be women who underwent cervical screening. A joint decision was made by the study team to forgo the stratified analysis by vaccination status because there were few women who had both been vaccinated with Gardasil and undergone cervical cancer screening. Thus, the number of participants analyzed is zero.

The percentage of participants with liquid-based cervical cytology samples positive for HPV 6, 11, 16, and 18 was to be analyzed by Gardasil vaccination status.
