Anti-Rota Virus (Anti-RV) Immunoglobulin A (IgA) Antibody Concentrations in the Human Rotavirus (HRV) Liquid Formulation Groups (Liq_A, Liq_B and Liq_C) Primary · At Month 2-4 (i.e. approximately 1-month or 2-months after second dose of HRV vaccine according to the immunisation schedule for RV vaccine administration in participating countries)

Antibody concentrations against Rota Virus (RV) were determined as Geometric Mean Antibody Concentration (GMC) and expressed as Units per milliliter (U/mL).

Percentage of Seroconverted Subjects With RV Antibody Concentrations Above or Equal to Cut-off Value in Porcine Circovirus (PCV) -Free Liquid HRV Vaccine (Pooled HRV Liquid Group) and Control Group Primary · At Month 2-4 (i.e. approximately 1-month or 2-months after second dose of HRV vaccine according to the immunisation schedule for RV vaccine administration in participating countries)

Seroconversion rate (SCR) was defined as the percentage of subjects who were initially seronegative (i.e., with anti-RV IgA antibody concentration less than (\<) 20 U/mL before the first dose of HRV vaccine) and developed anti-RV IgA antibody concentration greater than or equal to (≥) 20 U/mL at Month 2-4 (1-2 months after dose 2). SCR was analysed using Enzyme Linked Immunosorbent Assay (ELISA). For this outcome measure, the three groups (Liq\_A, Liq\_B \& Liq\_C) were pooled into a single group (Liq\_Pool group) as they all received PCV free-liquid HRV vaccine, and as pre-specified in the p

Antibody concentrations against RV were determined as GMCs and expressed as U/mL. For this outcome measure, the three groups (Liq\_A, Liq\_B \& Liq\_C) were pooled into a single group (Liq\_Pool group) as they all received PCV free-liquid HRV vaccine, and as pre-specified in the protocol, the immunological non-inferiority of the Liq\_Pool group was compared to the currently licensed lyophilized HRV vaccine (Lyo\_Control group) in terms of antibody concentrations at 1-2 months after Dose 2.

Sponsor's own description

The purpose of this study is to evaluate the clinical consistency of three production lots of the Porcine circovirus (PCV)-free liquid formulation of oral live attenuated human rotavirus (HRV) vaccine and to evaluate the PCV-free liquid formulation of HRV vaccine as compared to the currently licensed lyophilised formulation of the HRV vaccine in terms of immunogenicity, reactogenicity and safety when administered as a two-dose vaccination in healthy infants starting at age 6-12 weeks. No new subjects will be enrolled in the extension phase of the study.
