Study Endpoints

Primary Endpoints

Antibody Titers Against Varicella Zoster Virus (VZV)
At 43-57 days after the first vaccine dose (Week 6)

Antibody titers have been assessed by immunofluorescence assay (IFA) and presented as geometric mean titers (GMTs), for initially seronegative subjects \[with anti-VZV titer below (\<) 1:4\].

Antibody Concentrations Against Varicella Zoster Virus (VZV)
At 43-57 days after the first vaccine dose (Week 6)

Antibody concentrations have been assessed by enzyme-linked immunosorbent assay (ELISA), presented as geometric mean concentrations (GMCs) and expressed in milli-international units per milliliter (mIU/mL), for initially seronegative subjects \[with anti-VZV concentration below (\<) 25 mIU/mL\].

Secondary Endpoints

Number of Seroconverted Subjects for Varicella Antibodies
At 43-57 days post-Dose 1 (Week 6) and 86-114 days post-Dose 2 (Week 12)
Number of Subjects With Anti-VZV Antibody Concentrations Above Cut-off Values
At 43-57 days post-Dose 1 (Week 6) and 86-114 days post-Dose 2 (Week 12)
Antibody Titers Against Varicella Zoster Virus (VZV)
At 86-114 days after the second vaccine dose (Week 12)

Frequently asked questions about Varilrix

What is Varilrix used for?

Varilrix is a vaccine being studied for the prevention of varicella, the disease caused by the varicella-zoster virus. It is currently in Phase 2 clinical development and is being investigated for use in children as young as 11 months.

Who makes Varilrix?

Varilrix is being developed by GSK plc, a global biopharma company listed on the London Stock Exchange under the ticker GSK. The company is conducting clinical trials to evaluate the vaccine's safety and immunogenicity.

What phase is Varilrix in?

Varilrix is in Phase 2 clinical development. It is an investigational vaccine and has not yet been approved by regulatory authorities. One Phase 2 trial has been completed, and the vaccine remains under evaluation.

What clinical trials is Varilrix in?

Varilrix has been studied in one completed Phase 2 clinical trial, identified as NCT00568334. This trial evaluated two formulations of the varicella vaccine in 244 healthy participants in Czechia and Hungary.

Is Varilrix the same as the varicella vaccine?

Varilrix is a varicella vaccine, meaning it is designed to protect against chickenpox. It is being developed as a preventive measure for varicella infection, and the clinical trial data supports its potential use in this indication.
