A Study to Test 2 Doses of the HRV Vaccine Given With or Without OPV in Healthy Infants in Bangladesh

A Study to Test 2 Doses of the HRV Vaccine Given With or Without OPV in Healthy Infants 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

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).

"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."

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.

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.

Inclusion criteria: Healthy infants aged 6 weeks±1 at first study vaccination. Exclusion criteria: Malnutrition, no history of rotavirus gastroenteritis, allergic disease or chronic gastrointestinal disease, not received protocol-prohibited treatment.

Patient-level data for this study will be made available through www.clinicalstudydatarequest.com following the timelines and process described on this site.
