Study No.: SPD (Flu-Laval-104) Title: A Phase II randomized study to evaluate the immunogenicity, safety and tolerance of three formulations of Fluviral S/F influenza vaccine and Vaxigrip in healthy adults years of age and 65 years of age. Fluviral S/F: ID Biomedical s* trivalent split-virion influenza vaccine (FluSF). Vaxigrip : Sanofi-Pasteur s trivalent split-virion inactivated influenza vaccine (Vax). *ID Biomedical has been taken over by GlaxoSmithKline Biologicals. Rationale: The aim of this study was to evaluate the immunogenicity of 3 formulations of FluSF compared to Vax. All vaccines in the trial were formulated with virus strains recommended for the influenza season. Phase: II Study Period: 11 October 2004 to 04 June 2005 Study Design: A randomized, double-blind, active controlled, multicenter study with 2 age groups, each divided in 4 treatment groups (1:1:1:1). Centers: 10 study centers in Canada Indication: Immunization against influenza disease in subjects aged 50 to 64 years and elderly aged 65 years and older Treatment: The study groups were as follows: Group A: subjects received FluSF, : subjects received filtered formulation of FluSF, : subjects received filtered and thimerosal-reduced formulation of FluSF, : subjects received Vax. Subjects were administered one intra-muscular dose into the deltoid muscle of the non-dominant arm. Objectives: To describe the immunogenicity, as assessed by serum hemagglutination inhibition (HAI) titers, of FluSF sterilefiltered formulations and comparator products based on: Seroconversion rates (at least a four-fold rise in reciprocal titer or change from undetectable (< 10) to a reciprocal titer of 40); Seroprotection rates (Day 21 HAI reciprocal titer of 40, regardless of pre-immunization level); Geometric mean reciprocal titers; Geometric mean fold-rise in titer (GMFR); To compare sterile-filtered FluSF results with published Committee for Proprietary Medicinal Products (CPMP) criteria for the seroconversion, seroprotection, and GMFR. Primary Outcome/Efficacy Variable: Immunogenicity: For each of the 3 viral antigens separately in the 4 treatment groups and in the pooled group receiving FluSF sterilefiltered formulations (groups B plus C) seroconversion* rate seroprotection** rate Geometric mean fold-rise (GMFR***) in HAI titer *Seroconversion is defined as either a 4-fold increase in reciprocal HAI titer post-vaccination (Day 21) compared to prevaccination (Day 0) or a rise of undetectable HAI titer (i.e., <10) pre-vaccination (Day 0) to an HAI titer 40 postvaccination (Day 21) ** Seroprotection is defined as a HAI titer 40 at Day 21 post-vaccination ***GMFR is defined as the ratio of post-vaccination (Day 21) Geometric Mean Titer (GMT) to the pre-vaccination (Day 0) Geometric Mean Titer (GMT). Secondary Outcome/Efficacy Variable(s): Safety: Frequency and severity of adverse events (AEs) through 6 months post-immunization, including solicited local and systemic vaccine reactions from Day 0 to Day 3. Severity data were not readily available in the report for unsolicited AEs.

2 Statistical Methods: The analyses were performed on the Total Vaccinated cohort and the According-To-Protocol (ATP) for immunogenicity. - The Total Vaccinated cohort included all subjects who received the study vaccine. - The ATP cohort for immunogenicity included all vaccinated subjects who complied with the procedures defined in the protocol and for whom immunogenicity data were available. Analysis of immunogenicity: The analysis of immunogenicity was performed on the ATP cohort for immunogenicity. Geometric mean titers (GMTs) and seroprotection rates for each vaccine strain were computed at pre- and postvaccination for each vaccine group and for each age group with 95% confidence intervals (CIs). Seroconversion rates and GMFR for each vaccine strain were computed at post-vaccination for each vaccine group and each age group. The 95% CIs were also calculated for seroconversion rate, the lower limit for the 95%CI was calculated for GMFR. According to a CBER request, the results of immunogenicity for all study population including subjects below 60 were evaluated by comparison with the European Union (EU) requirements for Influenza vaccines [Committee for Proprietary Medicinal Products (CPMP)] for elderly population. The CPMP standards for elderly vaccinees are for each vaccine strain, the lower 95% confidence bound for : - seroconversion rate : 30% - seroprotection rate : 60% - GMFR : 2 Analysis of safety: The analysis of safety was performed on the Total Vaccinated cohort. For each solicited symptom, the percentage of subjects with solicited symptom was summarized for each vaccine group 30 minutes after vaccine dose and during 4 days (Day 0-3) follow-up period after vaccination. The percentage of subjects reporting unsolicited AEs within 22 days (Day 0-21) and 6 months following administration of vaccine(s) was tabulated according to the Medical Dictionary for Regulatory Activities (MedDRA) preferred term for each vaccine group. The occurrence of serious adverse events (SAEs) was tabulated according to the MedDRA preferred term for each vaccine group during the entire study period including a long-term safety follow-up period of 6 months. Study Population: Healthy male or female adults (50-64 years of age or elderly 65 years of age) who passed a satisfactory medical assessment with no clinically significant and/or relevant abnormalities (medical and concomitant medication history, physical examination). If the subject was female and of childbearing potential, she had to be abstinent or to have used contraceptive precautions for 30 days prior to vaccination. Subjects had to understand and be able, willing and likely to fully comply with study procedures and restrictions. Written informed consent was obtained prior to study entry. Subjects who received an influenza vaccine within 6 months prior to dosing were excluded.

At the same time point, at least 98.68%, 80.26% and 56.58% of the subjects 65 years of age had HAI titers 40 for A/Wyoming, A/Caledonia and B/Jiangsu vaccine strains, respectively. In all groups, redness was the most frequently reported local immediate complaint while pain at the injection site was the most frequently reported solicited local symptom (Day 0-3). Low body temperature was the most frequently reported solicited general immediate complaint and symptom in all groups. At least one unsolicited AE was reported between Day 0 and 21 by 67 (40.9%), 84 (51.5%), 73 (44.2%) and 79 (47.6%) subjects of the Groups A-D, respectively. Between Month 0 and Month 6, unsolicited AEs were reported by 125 (76.2%), 128 (78.5%), 130 (78.8%) and 130 (78.3%) subjects of the Groups A-D, respectively. SAEs were reported by 14 subjects (2 in Group A, 2 in Group B, 6 in, and 4 in ). These SAEs were considered by the investigators to be not related to the study vaccination. No fatal SAEs were reported. Date Updated: 20-May-2015
