Study to Evaluate the Impact of Reactogenicity on Quality of Life (QoL), After Administration of GlaxoSmithKline (GSK) Biologicals' Candidate Herpes Zoster Subunit (HZ/su) Vaccine (GSK1437173A) in Adults ≥ 50 Years of Age

Phase 3

Completed

• Conditions: Herpes Zoster
• Interventions: Biological: GSK Biologicals Herpes Zoster subunit (HZ/su) vaccine (GSK 1437173A)

• Registration Number: NCT02979639
• Lead Sponsor: GlaxoSmithKline

Brief Summary

The purpose of this study is to evaluate the impact of reactogenicity of GSK Biologicals' HZ/su vaccine on Quality of Life (QoL) in adults ≥ 50 years of age

Detailed Description

The study will evaluate the impact of HZ/su vaccination on the QoL, 400 adults ≥ 50 years of age (YOA). Subjects will be asked to respond to a series of SF-36 and EQ-5D questionnaires before and after vaccination following a 2 month schedule. To estimate the impact of reactogenicity on an individual's physical functioning (PF) and QoL, the study will compare subject questionnaire responses made during two periods, i.e., pre-vaccination and post-vaccination. The difference will be considered to be the effect of vaccination and reactogenicity on the PF and QoL. To characterize the study population and determine if frailty may influence reactogenicity and consequently the impact on QoL scores, the subjects' frailty status will be assessed at the first inclusion visit. In addition to the SF-36 and EQ-5D questionnaires, a more complete characterization of the reactogenicity of the vaccine will be made by including a detailed collection of the use of healthcare resources and the occurrence of symptoms through diary card data collection. Impact on days of work loss, both for the subject or for a caregiver, as applicable, will also be assessed.

Note that as a result of internal change in data standards terminology, the study data collected was converted to cDISC and the statistical analysis plan was amended accordingly. "Day 0" in the study design was replaced by "Day 1"; consequently, "Day n" was replaced by "Day n+1". Thus, the timeframes (Day 0, Day n) of Outcome Measures described in this study record are different to that denoted in the full protocol document posted.

Primary Outcome Measures

Name	Time	Method
Change in the Short Form 36-item-health Survey (SF36) Physical Functioning (PF) From Baseline Score to Mean Score After First Dose	From Baseline at Day -7 to Day 8 after first dose	Descriptive analysis of the mean and standard deviation (SD) of the change from baseline of the SF-36 physical functioning (PF) score pre- and post dose 1 overall. Changes in the score were measured as Baseline versus mean score over the period Day 2 to Day 8 after first vaccination. Baseline for dose 1 is defined as the mean of the assessments at Day -7 and Day 1. The post-vaccination completion of SF-36 questionnaires brought home by the subjects were Days 2 to 7, with Day 8 to be filled in at the site. The SF-36 scale scores are constructed following the summated ratings of the questions and standardized SF-36 scoring algorithm. Scores range from 0 to 100, with a higher score representing a higher level of functioning.

The post-vaccination completion of EQ-5D questionnaires brought home by the subjects were on Day 2 to Day 7, with Day 8 to be filled in at the site. The EQ-5D is a generic measure of health status that provides a simple description profile based on 5 items: mobility, self-care, usual activities, pain/discomfort and anxiety/depression, which are used to generate the EQ-5D index utility score. The EQ-5D index utility score ranges from 0 (worst health state) to 1 (perfect health state); 1 reflects the best outcome.
Change in QALY After Second Dose	From Day -7 to first dose until Day 8 after second dose (equivalent to study Days -7 to 68)	Descriptive analysis. QALY estimation is done from baseline score, based on EQ-5D questionnaires. Baseline versus combined score over the period Day 2 to Day 8 after each vaccination.

The EQ-5D is a generic measure of health status that provides a simple description profile based on 5 items: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. The 5 items are combined to generate health profiles (e.g. 1-no problem/no symptom) and profiles are subsequently converted to a continuous single index utility score (higher scores represent a better quality of life).
