Outcomes

Primary Outcome Measures

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)

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

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 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 seroconversion rates of 1-2 months after Dose 2.

Percentage of Seroconverted Subjects With RV Antibody Concentrations Above or Equal to 20 U/mL in Porcine Circovirus (PCV)-Free Liquid HRV Vaccine (Individual HRV Liquid Groups) and Lyophilised Control Group

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). The analysis was assessed to demonstrate the immunogenicity of PCV-free liquid HRV vaccine as compared to the currently licensed lyophilised HRV vaccine (individual HRV liquid groups) in terms of seroconversion rates 1-2 months after Dose 2.

Anti-RV IgA Antibody Concentrations in the PCV-free Liquid HRV Vaccine (Pooled HRV Liquid Group) and Lyophilised Control Group

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.

Anti-RV IgA Antibody Concentrations in the PCV-free Liquid HRV Vaccine (Individual HRV Liquid Groups) and Lyophilised Control Group

Antibody concentrations against RV were determined as GMCs and expressed as U/mL. The analysis was assessed to demonstrate the immunogenicity of the PCV-free liquid HRV vaccine (individual HRV liquid groups) to that of the currently licensed lyophilised HRV vaccine in terms of serum anti-RV IgA antibody concentrations 1-2 months after Dose 2.

Secondary Outcome Measures

Percentage of Subjects With Anti-RV IgA Concentrations (Pooled HRV Liquid Group)

Antibody concentrations ≥90 U/mL were determined and expressed as GMCs, assessed for the pooled HRV liquid groups and Control Group. The GMC calculations were performed by taking the anti-log of the mean of the log concentration transformations. 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 immunogenicity of the Liq_Pool group was compared to the currently licensed lyophilized HRV vaccine (Lyo_Control group) in terms of percentage of subjects with anti-RV IgA antibody concentrations ≥ 90 U/mL, 1-2 months after Dose 2

Percentage of Subjects With Anti-RV IgA Concentrations (Individual HRV Liquid Groups)

Antibody concentrations ≥90 U/mL were determined and expressed as GMCs, assessed for the individual HRV liquid groups and Control Group. The GMC calculations were performed by taking the anti-log of the mean of the log concentration transformations. The analysis was performed to assess the immunogenicity of the PCV-free liquid HRV vaccine (pooled HRV liquid groups) and the currently licensed lyophilised HRV vaccine, in terms of percentage of subjects with anti-RV IgA antibody concentrations ≥ 90 U/mL 1-2 months after Dose 2.

Number of Subjects With Any Solicited General Adverse Events (AEs).

Assessed solicited general AEs were cough/runny nose, diarrhea, fever (defined as temperature ≥ 38.0°C), irritability/fussiness, loss of appetite and vomiting. Any solicited general AE is defined as any occurrence of the specified symptom, irrespective of intensity grade and relationship to vaccination.

Number of Subjects With Any Unsolicited AEs.

An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Any is defined as the occurrence of any unsolicited AE irrespective of its intensity grade and relationship to vaccination.

Number of Subjects With Any Serious Adverse Events (SAEs)

SAEs assessed include any untoward medical occurrence that resulted in death, were life-threatening, required hospitalization or prolongation of existing hospitalization or resulted in disability/incapacity.

5. Study Description

Brief Summary

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.

Detailed Description

Experimental design: Phase IIIA, observer-blind, randomised (1:1:1:1), controlled, multi-centric, with four parallel groups and a staggered enrolment (Part A and Part B). Duration of the study: The intended duration of the study, per subject, will be approximately 7-8 months including the 6 months of extended safety follow-up period after the last dose of HRV vaccine. Epoch 001: Primary starting at Visit 1 (Day 0) and ending at the safety follow-up contact (Month 7-8). Primary completion Date (PCD): Visit 3 (Month 2-4). End of Study (EoS): Last testing results released of samples collected at Visit 3 or Last Subject Last Visit (LSLV) (Follow up contact at month 7-8). Study Groups: PCV-free HRV liquid formulation lot A (also referred to as Liq_A Group) PCV-free HRV liquid formulation lot B (also referred to as Liq_B Group) PCV-free HRV liquid formulation lot C (also referred to as Liq_C Group) GSK Biologicals' currently licensed lyophilised HRV formulation (also referred to as Lyo Group) Control:active control-GSK Biologicals' currently licensed lyophilised HRV vaccine Vaccination schedule: Two doses of HRV vaccine to be administered according to a 0, 1-2 month schedule according to the immunisation schedule for RV vaccine. Note that as a result of internal change in data standards terminology, the study data collected was converted to cDISC and the statistical analysis plan was amended accordingly. "Day 0" in the study design was replaced by "Day 1"; consequently, "Day n" was replaced by "Day n+1". Thus, the time frames (Day 0, Day n) of Outcome Measures described in this study record are different to that denoted in the full protocol document posted.
