General information about the trial
|
|||
Main objective of the trial |
To evaluate non-inferiority of GSK Biologicals' HRV liquid vaccine compared to GSK Biologicals' HRV lyophilized vaccine in terms of geometric mean concentrations (GMCs) for anti-RV antibodies, one month post dose 2 of HRV liquid vaccine and HRV lyophilized vaccine.
Criterion: Non-inferiority will be stated if the lower limit of the two-sided 95% confidence interval (CI) for the ratio of anti RV IgA antibody GMCs between HRV liquid vaccine over the HRV lyophilized vaccine, one month after dose 2 is greater than or equal to 0.5.
|
||
Protection of trial subjects |
All subjects were observed closely for 30 min following the administration of the vaccine, with appropriate medical treatment readily available in case of anaphylaxis. Vaccines were administered by qualified and trained personnel. Vaccines were administered only to eligible subjects that had no contraindications to any components of the vaccines. Subjects were followed-up for 30 days after the last vaccination.

Were there any global substantial amendments to the protocol? Yes | |||
Date |
Amendment |
||
24 Jul 2013 |
NDAC- Vaccines (New Drug Advisory Committee on Vaccines) of Drugs Controller General of India (DCGI) recommended to conduct this study as a Phase IV study instead of phase III as initially planned because Rotarix liquid file application is considered as a line extension of Rotarix Lyophilized formulation. The protocol was amended to adapt the change recommended by NDAC-Vaccines of DCGI. |
||
31 Oct 2017 |
- The phase of this clinical trial is revised from Phase IV to Phase III.
- The study objectives have been updated to include a confirmatory primary objective and the study has been powered accordingly.
- The statistical considerations have been revised to define the success criteria for the primary objective.
- Collection and testing of stool samples from subjects who develop gastroenteritis (GE) during the study period is removed.
- The study procedures, list of assays and section on biological samples evaluation have been updated accordingly. |
||
30 Oct 2019 |
- The PPS was modified to include subjects seroposi-tive at baseline.
- The statistical method to derive the 95% CI for the GMC group ratio was revised to be an ANCOVA.
- The seroconversion threshold was redefined to account for seropositive subjects at pre-vaccination. |
