Detailed Description
Infants will be identified through a community survey in urban neighborhoods in the city of Delhi, India and screened at 6 weeks of age if parental consent is available. They will be given the first dose of EPI vaccines at this age. Of those screened, eligible infants will be given the first administration of the test vaccine/placebo at 8 weeks of age if they meet the enrollment inclusion criteria, and consent is available. The safety profile will be studied through daily home visits for 14 days post administration. Stool specimens will be collected before vaccination (day 0) and on days 3, 7 and 28 post administration of vaccine/placebo. Subsequently, two contacts will be made; a home visit on day 21 and a clinic visit on day 28. On the day 28 visit, a stool and blood specimen will be collected. Prior to each administration of vaccine/placebo the infants will be assessed for any contraindications.
All screened infants will be offered EPI vaccines as scheduled. The second and third administration of study vaccine/placebo will be at 12 and 16 weeks of age and the same strategy will be followed for each of the three dosages The study vaccine/placebo are not being administered with the EPI vaccines even though in the future rotavirus vaccine and the EPI vaccines may be coadministered. For the purpose of this study this schedule is being adopted, as no data are available on the interaction of EPI vaccines with this rotavirus vaccine candidate.
Baseline sera will be collected at 6 weeks (at the time of screening) and again 4 weeks after administration of the vaccine/placebo in a randomly selected subsample after the first (60 infants), second (60 infants) and third (60 infants) administration of each dosage.
Clinical adverse events will be monitored and relatedness to vaccine/placebo administration assessed for 14 days after each administration of the dosage under study, whereas monitoring for symptoms of intussusception will be assessed throughout the 28 day follow up period. Laboratory adverse events will be monitored for upto 28 days after first administration of each dosage. After the 4 week follow up of the third administration of the vaccine/placebo of the lowest dosage (10^4.0) is completed for all enrolled infants and the data safety monitoring board (DSMB) meeting will be convened and the data from the study will be analyzed, the code broken. If the DSMB declares the dosage safe, guided by the apriori criteria, the team will move on to screening infants for the next higher dosage (10^5.0) and the strategy listed above will be repeated for a total of 180 enrolled infants (90 vaccinees/90 placebo). The DSMB will again meet to review the data available from this cohort (i.e. 10^5.0) and the team will proceed to screen infants for the next higher dosage (10^6.0) only if the former is declared safe.
At the end of the study i.e. after the last visit of the last participant, based on reactogenicity and immunogenicity profile of each dosage, the appropriate dosage will be selected for further clinical evaluation.
