Study Endpoints

Primary Endpoints

Geometric mean concentrations (GMCs) of immunoglobulin G (IgG) antibodies against measles, mumps, rubella, and varicella zoster virus (VZV) glycoprotein E (gE) after MMRVNS vaccine administration
At Day 43

This outcome measure evaluates immunological consistency.

Number of participants with seroresponse against measles, mumps, rubella, and VZV gE after MMRVNS or MMRV administration
At Day 43

This outcome measure evaluates immunological non-inferiority. Seroresponse is defined as post-vaccination IgG antibody concentrations equal to or above threshold values as follows: The seroresponse of a participant is: * zero (non-seroresponder) if the IgG concentration is below the seroresponse threshold of the assay, * One (seroresponder) if the IgG concentration is above or equal to the seroresponse threshold.

Frequently asked questions about MMRVNS vaccine

What is MMRVNS vaccine used for?

MMRVNS vaccine is an investigational combined measles, mumps, rubella and varicella vaccine being studied for use in healthy children to protect against measles, mumps, rubella and varicella (chickenpox). It is currently in Phase 3 clinical development and has not been approved by regulatory authorities.

Who makes MMRVNS vaccine?

MMRVNS vaccine is being developed by GSK plc, a biopharma company listed on the stock exchange under the ticker GSK. The company is conducting Phase 3 clinical trials to evaluate the vaccine's immune response and safety in healthy children.

What phase is MMRVNS vaccine in?

MMRVNS vaccine is currently in Phase 3 clinical development. It is an investigational vaccine, meaning it has not yet been approved by regulatory authorities. Two Phase 3 trials are ongoing or planned to assess its safety and immune response in children.

What clinical trials is MMRVNS vaccine in?

MMRVNS vaccine is being studied in two Phase 3 trials. NCT07406360 is recruiting 1,209 children aged 15 months to 6 years in the United States. NCT07742644, not yet recruiting, plans to enroll 1,860 children aged 4 to 6 years across the US, Argentina, Finland, Italy, Puerto Rico and Taiwan.

Is MMRVNS vaccine the same as MMRVNS?

Yes, MMRVNS vaccine is also known as MMRVNS. Both names refer to the same investigational combined measles, mumps, rubella and varicella vaccine being developed by GSK plc for use in healthy children.
