1 The study listed may include approved and non-approved uses, formulations or treatment regimens. The results reported in any single study may not reflect the overall results obtained on studies of a product. Before prescribing any product mentioned in this Register, healthcare professionals should consult prescribing information for the product approved in their country. Study No.: (ROTA-070 PMS) Title: Safety of GlaxoSmithKline (GSK) Biologicals oral live attenuated human rotavirus (HRV) vaccine, Rotarix or Rotarix liquid formulation (oral suspension or prefilled syringe) when administered according to the prescribing information in Korea. Rotarix (HRV): GSK Biologicals oral live attenuated human rotavirus (HRV) vaccine. Rationale: HRV lyophilised formulation and HRV liquid formulation (oral suspension as well as prefilled syringe) have both been registered in Korea. The purpose of this post marketing (PMS) study was to assess the safety of all of the HRV vaccine presentations when administered to infants aged from 6 weeks (first dose) to not more than 24 weeks (second dose). A total of at least 3000 evaluable subjects (approximately 500 per year for a period of 6 consecutive years) are required to be enrolled as per the regulations of the Korean Food and Drugs Administration (KFDA). This CTRS presents results collected during Years 1, 2, 3, 4, 5 (Year 1 & Year 2 data were combined and presented at the Year 2 time point and Year 3 & Year 4 data were combined and presented at the Year 4 time point) along with consolidated surveillance data from Year 1 to Year 6 time points Phase: IV Study Period: 02 September 2008 to 20 January 2010 (data lock point at Year 2) 16 August 2010 to 16 January 2012 (data lock point at Year 4) 09 September 2010 to 19 February 2013 (data lock point at Year 5) Year 1 to Year 6 study period: 02 September 2008 to 03 February 2014 (data lock point at Year 6) Study Design: Open, non-comparative, single group, multi-centre study. Centres: 35 centres in Korea (Year 2 time point) 20 centres in Korea (Year 4 time point) 13 centres in Korea (Year 5 time point). Total 83 centres in Korea (Year 1 Year 6 time points) Indication: Prevention of gastroenteritis (GE) caused by rotavirus (RV) in infants from the age of 6 weeks. Treatment: There was one study group, the. Subjects received 2 oral doses of HRV vaccine. The first dose was administered to infants from the age of 6 weeks. The second dose was given at least 4 weeks after Dose 1, preferably before the age of 16 weeks. The 2 doses had to be given before 24 weeks of age. Objective: To assess the safety of HRV lyophilised formulation or HRV liquid formulation (oral suspension or prefilled syringe) in infants when administered according to the prescribing information in Korea. Primary Outcome/Efficacy Variables: Safety: Analysis at Year 2: Occurrence of solicited adverse events (AEs) during the 8-day (Day 0 Day 7) follow-up after each vaccine dose. Occurrence of unsolicited AEs during the 31-day (Day 0 Day 30) follow-up period after each vaccine dose according to Medical Dictionary for Regulatory Activities (MedDRA) classification. Occurrence of serious adverse events (SAEs) during the entire post-marketing surveillance (PMS) period. Following protocol amendment, the outcome variables for the subsequent study periods were reformulated as below: Analysis at Years 3, 4, 5 & 6*: Occurrence of AEs during the 31-day (Day 0 Day 30) follow-up period after each vaccine dose according to MedDRA classification. Occurrence of SAEs during the entire PMS period. Outcome variables were not differentiated into primary and secondary in the study protocol, hence all were considered as primary outcome variables. *In line with the KFDA s request, the consolidated surveillance data from Year 1 to Year 6 time points were presented in place of Year 6. Secondary Outcome/Efficacy Variable(s): Not applicable. Statistical Methods:

2 The analysis was performed on the Total Vaccinated cohort, which included all vaccinated subjects with at least one dose of HRV vaccine administration documented. Analysis of Safety The analysis was performed on the Total Vaccinated cohort. For the Year 1 & 2 study period, the incidence of solicited symptoms occurring during the 8-day (Days 0 7) follow-up period after vaccination was tabulated with 95% confidence interval (CI). The same tabulation was performed for Grade 3 symptoms. The percentage of subjects with at least one report of unsolicited AEs during the 31-day (Days 0 30) follow-up period after each vaccine dose was tabulated according to MedDRA preferred terms for the Years 2 and 4 time points, and according to World Health Organisation s Adverse Reactions Terminology (WHO ART) Dictionary for the Year 5 and consolidated results from Year 1 to Year 6 time points. SAEs were collected and summarized according to MedDRA preferred terms up to Year 4 time point, and according to WHO ART Dictionary for the Year 5 and consolidated results from Year 1 to Year 6 time points. Study Population: Male or female subject of at least 6 weeks of age at the time of the first vaccination.

At least one SAE was reported for 6 (0.7%) subjects during the Year 1 & 2 study period, for 13 (1.2%) subjects during the Year 3 & 4 study period, for 4 (0.6%) subjects during the Year 5 study period and for 26 (0.8%) subjects during the Year 1 to Year 6 study period. All of the SAEs reported up to Year 6 were assessed by the investigators as not related to the vaccination; no fatal SAEs were reported up to Year 6. Date updated: 21-October-2014
