Safety and Protective Effect Study of GSK Biologicals' Human Papillomavirus (Types 16, 18) Vaccine, Adsorbed (GSK580299) in Healthy Female Subjects From the HPV-039 Study

Phase 4

Completed

• Conditions: Cervical Intraepithelial Neoplasia
• Interventions: Biological: HPV (Types 16, 18) Vaccine, Adsorbed

• Registration Number: NCT03629886
• Lead Sponsor: GlaxoSmithKline

Brief Summary

This study was designed to enable all subjects who received placebo in the HPV-039 study (NCT00779766), to also receive GSK Biologicals' Human Papillomavirus (Types 16, 18) Vaccine, Adsorbed. Safety data in terms of serious adverse events (SAEs), any adverse events (AEs)/SAEs leading to premature discontinuation of the study, potential immune mediated diseases (pIMDs) and pregnancies (and their outcomes) were collected during the study period.

In addition, this study assessed the long term protective effect of the vaccine, in an exploratory manner, in terms of rates of HPV-related (vaccine type) incident cervical infection up to approximately 10 years after vaccination in subjects who participated in HPV-039 study (NCT00779766).

Detailed Description

Treatment allocation depended on the randomization in the previous study i.e. only the subjects from the control group of HPV-039 study received HPV vaccination in the current study. Subjects who previously received the Human Papillomavirus (Types 16, 18) Vaccine, Adsorbed in HPV-039 study did not receive vaccination in this study.

Arm && Interventions

Group	Intervention	Description
Vacc-092 Group	HPV (Types 16, 18) Vaccine, Adsorbed	Healthy Chinese female subjects, above 26 years of age at study entry, who previously received placebo (control group) in HPV-039 study (NCT00779766), were intended to receive HPV vaccine in the current study and were to provide cervical samples before HPV vaccination.

Primary Outcome Measures

Name	Time	Method
Number of Subjects With Serious Adverse Events (SAEs) Related to Study Vaccine in Vacc-092 Group	During the entire study period (Day 1-Month 12)	SAEs assessed include any untoward medical occurrence that resulted in death, were life-threatening, required hospitalization or prolongation of existing hospitalization, resulted in disability/incapacity or was a congenital anomaly/birth defect in the offspring of a study subject. Related SAEs are those SAEs assessed by the investigator as related to vaccination in the study.

Secondary Outcome Measures

Name	Time	Method
Number of Pregnant Subjects Reported With Outcomes of Pregnancy in Vacc-092 Group	During the entire study period (Day 1-Month 12)	Pregnancy is the term used to describe the period in which a fetus develops inside a woman's womb or uterus. The subjects with confirmed pregnancies were followed up to determine the outcomes of the reported pregnancies. Outcomes of the reported pregnancies were: Live infant no apparent Congenital Anomaly (CA), Live infant CA, Elective termination no apparent CA, Elective termination CA, Spontaneous abortion no apparent CA, Spontaneous abortion CA, Stillbirth no apparent CA, Stillbirth CA, Ectopic pregnancy, Molar pregnancy, Lost to follow-up \& Pregnancy ongoing.
Number of Subjects With SAEs in Vacc-092 Group	During the entire study period (Day 1-Month 12)	SAEs assessed include any untoward medical occurrence that resulted in death, were life-threatening, required hospitalization or prolongation of existing hospitalization, resulted in disability/incapacity or was a congenital anomaly/birth defect in the offspring of a study subject.
Number of Subjects With Any Adverse Events or Serious Adverse Events (AE/SAE) Leading to Premature Discontinuation From the Study in Vacc-092 Group	During the entire study period (Day 1-Month 12)	AEs assessed include any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. For marketed medicinal products, this also includes failure to produce expected benefits (i.e. lack of efficacy), abuse or misuse. SAEs assessed include any untoward medical occurrence that resulted in death, were life-threatening, required hospitalization or prolongation of existing hospitalization, resulted in disability/incapacity or was a congenital anomaly/birth defect in the offspring of a study subject. Any is defined as the occurrence of any unsolicited AE/SAE regardless of intensity grade or relation to vaccination.
Incidence Rates of Incident Cervical Infection With Any Oncogenic HPV Type or Combination of Oncogenic HPV Types in HPV DNA Negative Subjects at Baseline, Regardless of Initial Serostatus in All Study Groups	From Month 0 in HPV-039 (NCT00779766) study [at the Day after Dose 1 (out of 3 doses administered in HPV-039)] until Month 120 (corresponding to Day 1 in the current study)	The IR (n/T) of incident cervical infection with any oncogenic HPV type or combination of oncogenic HPV types (per 100 Person-years rate) was calculated as the number of subjects reporting at least one event (n) in a group (assessed by detecting HPV DNA using PCR), over the sum of follow-up period expressed in years (T) in the same group, and multiplied by 100. Oncogenic HPV types assessed were HPV-16, -18, -31, -33, -35, -39, -45, -51, -52, -56, -58, -59, -66 and -68. HRW-HPV = High-risk (oncogenic) HPV types without HPV-16 or HPV-18: HPV-31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and 68. HR-HPV = High-risk (oncogenic) HPV types: HPV-16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and 68. For single type: Subjects DNA negative at Month 0 for the corresponding HPV type in NCT00779766 study. For combined types: Subjects DNA negative at Month 0 for at least one HPV type (subjects were in the analysis of at least 1 single type) in NCT00779766 study.
Number of Subjects With Potential Immune Mediated Diseases (pIMDs) in Vacc-092 Group	During the entire study period (Day 1-Month 12)	pIMDS are a subset of adverse events (AEs) that include autoimmune diseases and other inflammatory and/or neurologic disorders of interest which might or might not have an autoimmune aetiology.
Incidence Rates of Incident Cervical Infection With HPV-16 and/or HPV-18 (by PCR) in HPV DNA Negative Subjects at Baseline, Regardless of Initial Serostatus in All Study Groups	From Month 0 in HPV-039 (NCT00779766) study [at the Day after Dose 1 (out of 3 doses administered in HPV-039)] until Month 120 (corresponding to Day 1 in the current study)	The incidence rate (n/T) of incident cervical infection with HPV-16 and/or HPV-18 (per 100 Person-years rate) was calculated as the number of subjects reporting at least one event (n) in a group, over the sum of follow-up period expressed in years (T) in the same group, and multiplied by 100. Cervical infection caused by HPV Types 16 and 18 was assessed by detecting HPV DNA using Polymerase Chain Reaction (PCR). For single HPV type: Subjects DNA negative at Month 0 for the corresponding HPV type in study HPV-039 (NCT00779766). For combined HPV types: Subjects DNA negative at Month 0 for at least one HPV type (subjects were in the analysis of at least one single type) in study HPV-039 (NCT00779766).
Number of Subjects With SAEs Related to Study Participation in All Study Groups	During the entire study period (Day 1-Month 12)	SAEs assessed include any untoward medical occurrence that resulted in death, were life-threatening, required hospitalization or prolongation of existing hospitalization, resulted in disability/incapacity or was a congenital anomaly/birth defect in the offspring of a study subject. Related SAEs are those SAEs assessed by the investigator as activities related to study participation and not by study vaccine (e.g. SAEs due to invasive tests).
Incidence Rates of Incident Cervical Infection With HPV-16 and/or HPV-18 (by PCR) in HPV DNA Negative and Seronegative Subjects at Baseline in All Study Groups	From Month 0 in HPV-039 (NCT00779766) study [at the Day after Dose 1 (out of 3 doses administered in HPV-039)] until Month 120 (corresponding to Day 1 in the current study)	The incidence rate (n/T) of incident cervical infection with HPV-16 and/or HPV-18 (per 100 Person-years rate) was calculated as the number of subjects reporting at least one event (n) in a group, over the sum of follow-up period expressed in years (T) in the same group, and multiplied by 100. Cervical infection caused by HPV Types 16 and 18 was assessed by detecting HPV DNA using Polymerase Chain Reaction (PCR). For single HPV type: Subjects DNA negative at Month 0 and seronegative at Month 0 for the corresponding HPV type in study HPV 039 (NCT00779766). For combined HPV types: Subjects DNA negative at Month 0 and seronegative at Month 0 for at least one HPV type (subjects were in the analysis of at least one single type) in study HPV 039 (NCT00779766).
