Trial overview
Official title: A phase IIIb, partially blind, randomized, placebo-controlled study to asses the effect on immunogenicity of administration of vaccine without buffering agent and to assess heat stability in terms of immunogenicity, reactogenicity and safety of GlaxoSmithKline Biologicals’ oral live attenuated human rotavirus (HRV) vaccine following a 0, 2 month schedule, in healthy infants previously uninfected with human rotavirus
Trial description: Rotavirus (RV) is the most important cause of acute gastroenteritis (GE) requiring hospitalization of infants and young children in developed and developing countries and can be a frequent cause of death in children less than 5 years of age. GSK Biologicals has developed a vaccine against human rotavirus gastroenteritis. In this study, the immunogenicity, reactogenicity and safety of the HRV vaccine will be evaluated when stored or reconstituted in circumstances different from the recommendations: i.e. when not reconstituted with a buffer or when stored for 7 days at 37°C before reconstitution. In addition, the effect of feeding will be explored for HRV vaccine reconstituted without buffer.
Primary purpose:
Prevention
Trial design:
Parallel Assignment
Masking:
Not applicable
Allocation:
Randomized
Primary outcomes:
Percentage of subjects with vaccine take
Timeframe: At 2 months post-Dose 2
Secondary outcomes:
Percentage of subjects who seroconverted (percentage of subjects with concentrations ≥ 20 U/mL in subjects who were negative for rotavirus (RV) before vaccination)
Timeframe: At 2 months post-Dose 2
Evaluation of the serum anti-RV IgA (immunoglobulin A) antibody concentrations expressed as Geometric Mean Concentrations (GMC)
Timeframe: At 2 months post-Dose 2
Rotavirus antigen shedding in planned stool samples
Timeframe: At Day 0, Day 7 and Day 15 post each study vaccine dose
Presence of RV in gastroenteritis (GE) episode stools collected
Timeframe: From Dose 1 of HRV vaccine/placebo up to 2 months post-Dose 2
For each type of solicited symptoms, occurrence of the symptom
Timeframe: Within the 15-day (Day 0-14) solicited follow-up period after each study vaccine dose
Occurrence of any Grade 2 or Grade 3 fever, vomiting or diarrhea
Timeframe: Within the 15-day (Day 0-14) solicited follow-up period after each study vaccine dose
Occurrence of unsolicited adverse events (AEs) according to Medical Dictionary for Regulatory Activities (MedDRA) classification
Timeframe: Within 31 days (Day 0-30) after each study vaccine dose
Occurrence of serious adverse events (SAEs) according to MedDRA classification
Timeframe: Throughout the study period (Day 0 to Month 4)

Accepts healthy volunteers
Yes
- A male or female between, and including, 6 and 12 weeks (42-90 days) of age at the time of the first vaccination.
- Written informed consent obtained from the parent or guardian of the subject.
- Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine(s) within 30 days preceding the first dose of study vaccine or placebo, or planned use during the study period.
- Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs prior to the first vaccine dose, since birth. (For corticosteroids, this will mean prednisone, or equivalent, greater than or equal to 0.5 mg/kg/day. Inhaled and topical steroids are allowed.)
Inclusion and exclusion criteria
Inclusion criteria:
- Written informed consent obtained from the parent or guardian of the subject.
- Free of obvious health problems as established by medical history and clinical examination before entering into the study.
A male or female between, and including, 6 and 12 weeks (42-90 days) of age at the time of the first vaccination.
Exclusion criteria:
- Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs prior to the first vaccine dose, since birth. (For corticosteroids, this will mean prednisone, or equivalent, greater than or equal to 0.5 mg/kg/day. Inhaled and topical steroids are allowed.)
- Planned administration of a vaccine (except routine paediatric vaccines) not foreseen by the study protocol. (If exceptionally OPV is given, this should be administered at least 14 days apart from the HRV vaccine or placebo dose.)
- Any clinically significant history of chronic gastrointestinal disease including any uncorrected congenital malformation of the GI tract or other serious medical condition as determined by the investigator.
- History of allergic disease or reactions likely to be exacerbated by any component of the vaccine.
- Any confirmed or suspected immunosuppressive or immunodeficient condition based on medical history and physical examination (no laboratory testing is required).
- Major congenital defects or serious chronic illness.
- Gastroenteritis within 7 days preceding the study vaccine administration (warrants deferral of the vaccination).
- Administration of immunoglobulins and/or blood products since birth or planned administration during the study period. Oral intake of immunoglobulins via e.g. breastfeeding is allowed.
- Previous confirmed occurrence of RV gastroenteritis.
Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine(s) within 30 days preceding the first dose of study vaccine or placebo, or planned use during the study period.
