About this study

Official title: A Long-term, Open, Follow-up of the Immunogenicity and Safety of GlaxoSmithKline Biologicals' HPV-16/18 L1/AS04 Vaccine in Healthy Female Subjects Vaccinated Either Pre- or Post-menarche in the Primary Study

The study will be extended for subjects who received all three doses of vaccine in Finland, Denmark and Estonia to determine long-term safety and immunogenicity of the HPV-16/18 vaccine. Human Papilloma virus (HPV) are viruses that cause a common infection of the skin and genitals in men and women. Several types of HPV infection are transmitted by sexual activity and, in women, can infect the cervix (part of the uterus or womb). This infection often goes away by itself, but if it does not go away (this is called persistent infection), it can lead in women over a long period of time to cancer of the cervix. If a woman is not infected by HPV, it is very unlikely that she will get cervical cancer. This study will evaluate the consistency of consecutive vaccine lots and the non-inferiority of modified manufacturing processes of GlaxoSmithKline Biologicals HPV-16/18 vaccine and the vaccine safety, over 12 months, in young adolescents and women of 10-25 years of age at study start.

Read the detailed description

Approximately 750 study subjects received different lots of the HPV vaccine administered intramuscularly according to a 0-1-6 month schedule.

The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

Study groupRoleWhat they receive
Cervarix New ProcessExperimentalSubjects aged 15 to 25 years received 3 doses (at Months 0, 1 and 6) of Cervarix™ (human papillomavirus [HPV]) produced with the new manufacturing process.
Receives: Biological: Cervarix™
Cervarix Old Process GroupExperimentalSubjects aged 15 to 25 years who received 3 doses (at Months 0, 1 and 6) of Cervarix™ (human papillomavirus [HPV]) produced with the old manufacturing process.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Titers of Anti-human Papilloma Virus 16 (Anti-HPV-16) and Anti-human Papilloma Virus 18 (Anti-HPV-18) Antibodies

    Titers are given as Geometric Mean Titers (GMTs) expressed as Enzyme-linked Immunosorbent Assay Units Per Milliliter (EL.U/mL).

    *Data for Month 18 outcome variables were incorporated into the Month 24 analyses.

    Measured: At months 18*, 24, 36 and 48

Secondary outcomes (4)
  1. Titers of Anti-human Papilloma Virus 16 (Anti-HPV-16) and Anti-human Papilloma Virus 18 (Anti-HPV-18) Antibodies in Cervical Samples

    Titers are given as Geometric Mean Titers (GMTs) expressed as EL.U/mL.

    Measured: At months 24, 36, and 48

  2. Titers of Anti-HPV-16 and Anti-HPV-18 Immunoglobulin G (IgG) Antibodies in Blood Samples

    Titers are given as Geometric Mean Titers (GMTs) expressed as EL.U/mL.

    Measured: At Months 24, 36 and 48

  3. Number of Subjects Reporting Pregnancies, New Onset Chronic Diseases (NOCDs) and Other Medically Significant Conditions (MSCs)

    NOCDs assessed include e.g. autoimmune disorders, asthma, type I diabetes. MSCs assessed include adverse events prompting emergency room or physician visits that are not related to common diseases or serious adverse events (SAEs) that are not related to common diseases.

    Measured: Throughout the study period (up to Month 48)

  4. Number of Subjects Reporting SAEs

    SAEs assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization, result in disability/incapacity or are a congenital anomaly/birth defect in the offspring of a study subject.

    Measured: Throughout the study period (up to Month 48)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Cervarix™ in people with Papillomavirus Type 16/18 Infection and Cervical Intraepithelial Neoplasia, run by GlaxoSmithKline at 1 site in Estonia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 May 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Estonia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 2 Mar 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Titers of Anti-human Papilloma Virus 16 (Anti-HPV-16) and Anti-human Papilloma Virus 18 (Anti-HPV-18) Antibodies (time frame: At months 18*, 24, 36 and 48). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 May 2017.
