A Study to Test 2 Doses of the HRV Vaccine Given With or Without OPV in Healthy Infants in Bangladesh
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The main objective of this study is to provide immunogenicity data for GSK Biologicals' HRV vaccine when co-administered with OPV or when given alone (HRV vaccine dose given 15 days after the OPV dose).
Condition or disease
"The study will have four groups: Group HRV + OPV, Group HRV alone, Group Placebo + OPV and Group Placebo alone. Two-dose immunisation will be administered in healthy infants at approximately 12 and 16 weeks of age. Immunogenicity, reactogenicity and safety relative to the placebo will also be evaluated. Treatment allocation: randomized (2:2:1:1). Routine EPI vaccines should be administered during the study following the EPI recommendation in Bangladesh."
Evaluate Immunogenicity, Reactogenicity & Safety of 2 Doses of GSK Biologicals' Oral Live Attenuated HRV Vaccine (RIX4414 at 106.5 CCID50) When Given Concomitantly With OPV Versus Given Alone (HRV Vaccine Dose Given 15 Days After the OPV Dose) in Healthy Infants in Bangladesh
Endpoints : Safety/immunogenicity.Immunogenicity of GSK Biologicals' HRV vaccine in terms of anti-rotavirus IgA antibody seroconversion at Visit 6 in the group receiving of HRV vaccine concomitantly with OPV versus placebo group.
Secondary Outcome Measures
Immunogenicity of GSK Biologicals' HRV vaccine in terms of anti-rotavirus IgA antibody seroconversion, vaccine take, and rotavirus shedding at Visit 6 in each group; Immunogenicity of OPV at Visit 6 in each group; Reactogenicity and safety in each group.
