About this study

Official title: An Observational Cohort Study to Assess the Risk of Autoimmune Diseases in Adolescent and Young Adult Women Aged 9 to 25 Years Exposed to Cervarix® in the United Kingdom

This is an observational cohort study to assess the risk of autoimmune disease(s) within 12 months of receiving the first dose of Cervarix® in the exposed cohort and over a comparable period in the unexposed cohorts.

This is an alternative study by GSK using the CPRD database in the UK to fulfil the US FDA safety commitment. The UK has had sufficient Cervarix® vaccination coverage during the period mid-September 2008 to 2011 to allow suitable data to be collected.

Read the detailed description

GSK's vaccine Cervarix® protects against Human Papilloma Virus Types-16 and 18-related pre-cancerous lesions. GSK is committed by the US Food and Drug Administration (FDA) to conduct a safety study to evaluate the incidence of new neurological and eye-related autoimmune diseases and other pre-specified autoimmune diseases in subjects receiving Cervarix® in the US. Because of the very low Cervarix® uptake in the US, the observational GSK study to address this commitment is due to be stopped, as it will take too long to recruit the target subjects.

The unexposed male cohorts will be enrolled in order to assess a possible change over time in the incidence rate of new onset of autoimmune disease(s) (NOAD) in the UK Clinical Practice Research Datalink General Practitioner OnLine database (CPRD GOLD) independent of Cervarix® introduction. The cohorts will be frequency matched for the age (age class of one year) and practice region identifier at reference date (age at first dose of Cervarix).

Additionally, the reference date (time = 0) for the vaccinated (exposed) cohort will be the date of the first dose of Cervarix® recorded in CPRD GOLD. The reference date for the unexposed (unvaccinated) cohorts will be a date randomly selected among the reference dates of the exposed subjects and minus 3 years for the historical cohorts.

The other observational study model is a self-control case-series (SCCS) analysis for confirmed NOAD in the exposed female cohort, using a risk period of one year after the first Cervarix® dose, a control period of one year and a six month buffer period between risk and control periods.

Human Papillomavirus Bivalent (Types 16 and 18) vaccine (recombinant) exposed cohort was investigated between 1-SEP-2008 and 31-AUG-2010.

The unexposed concurrent male cohort was investigated between 1-SEP-2008 and 31-AUG-2010.

Unexposed historical female and male cohorts were investigated between 1-SEP-2005 and 31-AUG-2007.

What is being measured

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

  1. Occurrence of new onset of confirmed autoimmune disease for neuroinflammatory/ophthalmic autoimmune diseases

    Neuroinflammatory/ophthalmic autoimmune diseases: -Multiple Sclerosis; -Transverse myelitis; -Optic neuritis; -Guillain-Barré syndrome, including Miller Fisher syndrome and other variants; -Other demyelinating diseases: -Acute disseminated encephalomyelitis, including site specific variants: e.g. non-infectious encephalitis, encephalomyelitis, myelitis, myeloradiculomyelitis; -AI peripheral neuropathies and plexopathies (including chronic inflammatory demyelinating polyneuropathy, multifocal motor neuropathy and polyneuropathies associated with monoclonalgammopathy); -Auto-immune uveitis;

    Measured: During the period of 1 year following administration of the first dose of Cervarix® (risk period) among an exposed cohort and during an equivalent time period in the unexposed cohorts

  2. Occurrence of new onset of confirmed autoimmune disease for other autoimmune diseases

    Other autoimmune diseases: -Systemic lupus erythematous; -Autoimmune (AI) disease with rheumatologic conditions: -Rheumatoid arthritis (RA);-Juvenile rheumatoid arthritis (JRA); -Still's disease; -Psoriatic arthritis; -Ankylosing Spondylitis; -AI haematological conditions: -Idiopathic thrombocytopenic purpura (ITP); -AI haemolytic anaemia; -AI endocrine conditions: -Type 1 diabetes mellitus; -AI thyroiditis including Hashimoto's disease, Graves' /Basedows' disease; -Inflammatory bowel / hepatic diseases: -Crohn's diseases; -Ulcerative colitis; -Autoimmune hepatitis;

    Measured: During the period of 1 year following administration of the first dose of Cervarix® (risk period) among an exposed cohort and during an equivalent time period in the unexposed cohorts

Secondary outcomes (3)
  1. Occurrence of Guillain Barré syndrome (including Miller Fisher syndrome and other variants), and autoimmune haemolytic anaemia

    Measured: Within 2 months following the administration of the first dose of Cervarix®

  2. Occurrence of idiopathic thrombocytopenic purpura (ITP)

    Measured: Within six months following the administration of the first dose of Cervarix®

  3. Occurrence of new onset of individual confirmed autoimmune disease

    Occurrence of multiple sclerosis, transverse myelitis, optic neuritis, other demyelinating diseases, auto-immune uveitis, systemic lupus erythematous (SLE), rheumatoid arthritis (RA), juvenile rheumatoid arthritis (JRA), Still's disease, psoriatic arthritis, ankylosing spondylitis, type 1 diabetes mellitus, auto-immune thyroiditis (including Hashimoto's disease, Graves'/Basedows' disease), and inflammatory bowel / hepatic disease (Crohn's disease, ulcerative colitis and autoimmune hepatitis)

    Measured: Within 1 year following the administration of the first dose of Cervarix®

Questions about this trial

What is this clinical trial studying?

An observational study of Infections, Papillomavirus, run by GlaxoSmithKline.

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 17 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 26 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.

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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Occurrence of new onset of confirmed autoimmune disease for neuroinflammatory/ophthalmic autoimmune diseases (time frame: During the period of 1 year following administration of the first dose of Cervarix® (risk period) among an exposed cohort and during an equivalent time period in the unexposed cohorts). The study lists 2 primary outcomes in all. 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 26 Dec 2016.
