About this study
Official title: Immunogenicity and Safety Study of GSK Biologicals' Combined Measles-mumps-rubella Vaccine in Subjects Seven Years and Older (209762)
The purpose of this study is to evaluate the immunogenicity and safety of GSK's trivalent MMR (Priorix®), comparing it to Merck"s MMR vaccine (M-M-R®II), which is approved for use in the US.
Read the detailed description
This study will evaluate the immunogenicity of GSK's trivalent MMR vaccine (referred to as INV_MMR vaccine) in contrast to the US standard of care (M-M-R®II, Merck and Company, referred to as COM_MMR) when both are used as a second dose in subjects 7 years of age and older. In this study, the INV_MMR vaccine may be administered as a second dose to persons with either a history or formal documentation of at least one dose immunization with any MMR vaccine. This study is intended to support licensure of GSK's MMR vaccine in the US.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Priorix® and Merck's M-M-R®II, Measles, Mumps, and Rubella Virus Vaccine in people with Rubella and Mumps, run by GlaxoSmithKline at 17 sites in 3 countries.
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 14 inclusion and 12 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 6 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 17 sites in United States, Slovakia, 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 10 Apr 2017). 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?
Anti-measles Virus Antibody Concentrations. (time frame: At Day 42). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02058563, which also lists 1 linked publication.
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 6 Jun 2018.
