A Post Marketing Surveillance (PMS) Study to Monitor the Safety of GlaxoSmithKline (GSK) Biologicals' Human Papillomavirus (HPV) Vaccine in Female Chinese Subjects

August 11, 2021 updated by: GlaxoSmithKline

A Prospective, Multi-centre Post Marketing Surveillance (PMS) Cohort Study to Monitor the Safety of GlaxoSmithKline (GSK) Biologicals' Human Papillomavirus (HPV)-16/18 L1 VLP AS04 Vaccine in Female Chinese Subjects Aged Between 9 and 45 Years, When Administered According to the Prescribing Information (PI) as Per Routine Practice.

The purpose of this prospective, multi-centre, PMS cohort study was to monitor the safety of Cervarix, which is the first HPV vaccine licensed for use in China, to help prevent cervical cancer caused by HPV types 16 and 18. The vaccine was approved by National Drug Administration of China (CNDA), in July 2016.

As per the CNDA commitment, this study collected data regarding the safety of the vaccine, related information on potential immune-mediated diseases (pIMDs); which are diseases that could affect the immune system, and the effect on pregnancy outcomes (POs) including birth defects in the newborn.

Cervarix was approved for use in females between 9-25 years of age, for the prevention of cervical cancer, cervical intraepithelial neoplasia grade 1 (CIN1), cervical intraepithelial neoplasia grade 2, grade 3 (CIN 2/3) and adenocarcinoma in situ caused by high-risk human papillomavirus (HR-HPV) types 16 and 18.

In May 2018, Cervarix was also approved for use in women of age up to 45 years.

The exposed set (ES) comprised 3013 subjects, who were vaccinated with Cervarix, on a voluntary basis, as per standard practice. The study collected information on any adverse event following immunisation, pIMDs, POs and congenital anomalies.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

9 years to 45 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

Healthy female Chinese subjects aged between 9 and 45 years, vaccinated on a voluntary basis as per standard practice.

Description

Inclusion Criteria:

  • Any Chinese female subject aged between 9 and 45 years, at the time of first vaccination dose, who received voluntary vaccination.
  • Subjects for whom the investigator believed that they or their parent(s)/LAR(s) could and complied with the requirements mentioned in the protocol (e.g., return for the subsequent dose of vaccination and follow-up visits) were included in the study.
  • Written informed consent was obtained from the subject. For subjects who were below the legal age of consent, written informed consent were obtained from the parent(s)/LAR(s) of the subject and informed assent were obtained from the subject according to EC requirement as well as local law.

Exclusion Criteria:

• Child in care

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Cervarix group
Healthy female Chinese subjects aged between 9 and 45 years, vaccinated according to the Prescribing Information (PI) as per routine practice.
Other: Safety data collection (following routine vaccination)

This study assessed the safety of GSK Biologicals' Human papillomavirus (HPV) vaccine when administered routinely according to the Prescribing Information in female Chinese subjects aged between 9 and 45 years.

The intervention consisted in the active surveillance of adverse events following immunization and pregnancy outcomes if the vaccine was administered inadvertently during pregnancy. Information of potential adverse events and pregnancy outcomes were collected at immunisation visits, telephone contacts and through spontaneous reporting by the patient/LAR/physician.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Any (Following Each Dose and Across Doses), Grade 3 (Across Doses) and Vaccine Related (Across Doses) Medically Attended Adverse Events Following Immunisation (AEFIs)
Time Frame: During the 30-day period following each immunisation with Cervarix (administered on Day 1, Month 1 and Month 6)
An adverse event following immunisation (AEFI) is defined as any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a vaccine. Medically attended AEFIs are defined as events leading to an otherwise unscheduled visit to or from medical personnel for any reason, including emergency room visits. Any Medically attended AEFIS are presented for each dose and across doses. Grade 3 Medically attended AEFI = an AEFI which prevented normal, everyday activities. Related Medically Attended AEFI = AEFI assessed by the investigator as related to the vaccination.
During the 30-day period following each immunisation with Cervarix (administered on Day 1, Month 1 and Month 6)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Any, Fatal and Vaccine Related Serious AEFIs (Across Doses)
Time Frame: Throughout the study period (From Day 1 to either 12 months following the third immunisation (Month 18) or 24 months following the first immunisation with Cervarix (Month 24) whichever occured first))
Serious AEFIs assessed included medical occurrences that resulted in death, were life threatening, required hospitalization or prolongation of hospitalization or resulted in disability/incapacity, or is a congenital anomaly/birth defect in the offspring of a participant. Any serious AEFI = If a medically attended AEFI led to hospitalisation (or met any other serious AEFI criteria). Fatal Serious AEFIs are those events that resulted in death. Related Serious AEFIs= AEFIs assessed by the investigator as causally related to the study vaccination.
Throughout the study period (From Day 1 to either 12 months following the third immunisation (Month 18) or 24 months following the first immunisation with Cervarix (Month 24) whichever occured first))
Number of Participants With Any, Grade 3 and Vaccine Related Potential Immune Mediated Diseases (pIMDs) (Across Doses)
Time Frame: Throughout the study period (from Day 1 up to either 12 months following the third immunisation (Month 18) or 24 months following the first immunisation with Cervarix (Month 24), whichever occured first))
pIMDs are a subset of AEFIs that included autoimmune diseases and other inflammatory and/or neurologic disorders of interest which might or might not have an autoimmune aetiology. Any was defined as the occurrence of any pIMD regardless of intensity grade or relation to vaccination. Grade 3 pIMDs = pIMDs which prevented normal, everyday activities. Related pIMDs = pIMDs assessed by the investigator as related to the vaccination.
Throughout the study period (from Day 1 up to either 12 months following the third immunisation (Month 18) or 24 months following the first immunisation with Cervarix (Month 24), whichever occured first))
Number of Participants Reporting Pregnancies and Outcomes of Reported Pregnancies
Time Frame: Throughout the study period (from Day 1 up to either 12 months following the third immunisation (Month 18) or 24 months following the first immunisation with Cervarix (Month 24), whichever occured first))
The number of participants reporting pregnancies and outcomes of reported pregnancies (elective abortion for medical reasons, spontaneous abortion or congenital anomaly) when Cervarix was administered to the participant, inadvertently within 60 days before pregnancy onset, or any time during pregnancy, was reported.
Throughout the study period (from Day 1 up to either 12 months following the third immunisation (Month 18) or 24 months following the first immunisation with Cervarix (Month 24), whichever occured first))
