Overview

Brief Summary

The purpose of this study is to assess the efficacy, immunogenicity and safety of GSK Biologicals' liquid human rotavirus vaccine in healthy Chinese infants 6 to 16 weeks of age.

Detailed Description

Subjects can receive routine childhood vaccination according to the expanded program of immunisation recommendations in China. There will be two treatment groups (liquid human rotavirus vaccine and placebo). The study will also have two immunogenicity subgroups comprising of few subjects from both the treatment groups. The immunogenicity subgroup 1 will assess the immunogenicity of the liquid human rotavirus vaccine and the immunogenicity subgroup 2 will assess the immunogenicity of liquid human rotavirus vaccine and also the immunogenicity of oral poliovirus vaccine and diphtheria tetanus and acellular pertussis vaccine given concomitantly with liquid human rotavirus vaccine or placebo. This protocol posting has been updated following the Protocol Amendment 2, dated 05 August 2011. The impacted section in the protocol posting is: Outcome Measures Section.

Eligibility Criteria

Inclusion Criteria

•Subjects who the investigator believes that their parents/Legally Acceptable Representatives can and will comply with the requirements of the protocol.
•A male or female infant of Chinese origin between, and including, 6 and 16 weeks of age at the time of the first vaccination.
•Written informed consent obtained from the parents/Legally Acceptable Representatives of the subject.
•Healthy subjects as established by medical history and clinical examination before entering into the study.
•Born after a gestation period of 36 to 42 weeks inclusive.

Exclusion Criteria

•Child in care.
•Use of any investigational or non-registered product other than the study vaccine within 30 days preceding the first dose of study vaccine, or planned use during the study period.
•Chronic administration of immunosuppressants or other immune-modifying drugs since birth.
•Planned administration/administration of a vaccine not foreseen by the study protocol within 14 days before each dose of study vaccine(s) and ending 14 days after the first dose of the human rotavirus vaccine or placebo except for the routine childhood vaccinations.
•Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational product.
•Any clinically significant history of gastrointestinal disease including any uncorrected congenital malformation (such as Meckel's diverticulum) of the gastrointestinal tract that would predispose for intussusception .
•Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.
•Family history of congenital or hereditary immunodeficiency.
•History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccine.
•Major congenital defects or serious chronic illness.

Outcomes

Primary Outcomes

Number of Subjects With Severe Episode(s) of Rotavirus Gastroenteritis (RVGE) Caused by the Circulating Wild Type (WT) Strains

Time Frame: From Month 1 ½ to Month 21

A gastroenteritis episode was classified positive for rotavirus (RV) and caused by the circulating wild-type (WT) RV strains if RV other than the vaccine strain was identified in a stool sample collected during the episode. Severe RVGE was defined as an episode of RV GE with score equal to or higher than (\>=) 11 on a 20-point Vesikari scoring system.

Secondary Outcomes

Number of Subjects With Any Solicited Local Symptoms Following Dose 2 of the Rotarix Vaccine/Placebo(Within the 8-day (Days 0-7) follow-up periods following Dose 2 of the Rotarix vaccine/placebo)
Number of Seroconverted Subjects for Anti-rotavirus (Anti-RV) Immunoglobulin A (IgA) Antibodies(At Month 2 and at 12 months of age)
Number of Subjects With Any Episode(s) of Rotavirus Gastroenteritis (RVGE) of Any Type.(From Month 1 ½ to Month 21)
Number of Subjects With Severe Episode(s) of Rotavirus Gastroenteritis (RVGE) of Any Type.(From Month 1 ½ to Month 21)
Number of Subjects With Any and Severe Gastroenteritis (GE) Due to Any Cause(From Month 1 ½ to Month 21)
Number of Subjects With Any Solicited General Symptoms Following Administration of the Co-administered EPI Vaccines(Within the 8-day (Days 0-7) follow-up periods following Doses 1 and 2 of the OPV vaccine and Dose 1 of the Infanrix vaccine)
Number of Subjects With Any Unsolicited Adverse Events (AEs)(Within the 31-day (Days 0-30) follow-up periods following any dose of the Rotarix vaccine or placebo)

Number of Subjects With Any Episode(s) of Rotavirus Gastroenteritis (RVGE) Caused by the Circulating Wild-type Strains(From Month 1 ½ to Month 21)
Number of Subjects With Any Serious Adverse Events (SAEs)(Throughout the entire study period (from Day 0 to Study End at Month 21))
Anti-rotavirus (Anti-RV) Immunoglobulin A (IgA) Antibody Concentrations.(At Day 0, Month 2 and at 12 months of age)
