Study to Evaluate Immunogenicity and Safety of GSK Biologicals' Herpes Zoster Subunit (HZ/su) Vaccine at 9 and 10 Years After Vaccine Administration and Assessment of Re-vaccination With 2 Additional Doses at 10 Years After Initial Vaccination, in Healthy Subjects Aged 60 Years of Age(YOA) and Older
- Conditions
- Herpes Zoster
- Interventions
- Biological: Herpes Zoster Vaccine GSK1437173A
- Registration Number
- NCT02735915
- Lead Sponsor
- GlaxoSmithKline
- Brief Summary
The purpose of this study is to evaluate the persistence of immune response to the HZ vaccine as well as safety up to 10 years after the first dose of initial vaccination course. This study will also assess immune responses after re-vaccination with 2 additional doses of the HZ/su administered at ten years after first dose of initial vaccination course from study Zoster-003 (NCT00434577).
- Detailed Description
In this LTFU study (ZOSTER-060), subjects who received 2 doses of HZ/su in the earlier Zoster-003 (NCT00434577) study will be followed up at Month 108/Year 9 and Month 120/Year 10 post first dose of vaccine for safety and immunogenicity (humoral and cellular). In order to assess the effect of re-vaccination with 2 additional doses of HZ/su vaccine, all the subjects will receive 2 additional doses of the HZ/su vaccine, on a 0, 2-month schedule at ten years after the initial vaccination course in study Zoster-003 (NCT00434577), and will be followed for reactogenicity, safety and humoral and cellular immunogenicity (including persistence).
In alignment with the previous persistence timepoints, this study has no control group.

- Subjects are expected to enter the study (or complete Visit 1) as of the time they turn 108 months after first vaccination of previous vaccination course with HZ/su and not later than 111 months.
- Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine during the period starting 30 days before the first study visit (Day -29 to Day 0), or planned use during the study period.
- Use or anticipated use of immunosuppressants or immune-modifying drugs during the period starting six months prior to study start and during the whole study period. This includes chronic administration of corticosteroids (>14 consecutive days of prednisone at a dose of ≥20 mg/day [or equivalent]), long-acting immune-modifying agents (e.g., infliximab) or immunosuppressive/cytotoxic therapy (e.g., medications used during cancer chemotherapy, organ transplantation or to treat autoimmune disorders).

- Administration or planned administration of a live vaccine in the period starting 30 days before the first dose of study vaccine and ending 30 days after the last dose of study vaccine, or, administration or planned administration of a non-replicating vaccine* within 8 days prior to or within 14 days after either dose of study vaccine.
E.g., inactivated and subunit vaccines, including inactivated and subunit influenza vaccines and pneumococcal conjugate vaccines.
- Previous vaccination against HZ since initial vaccination in Zoster-003.
- Administration of immunoglobulins and/or any blood products during the period starting 3 months before the study start, or planned administration during the study period.
- History of previous HZ.

Group Intervention Description GSK1437173A vaccine Group Herpes Zoster Vaccine GSK1437173A Subjects who completed vaccination course of 2 doses of HZ/su vaccine (group 50 μg gE/AS01B) in the study Zoster-003 (NCT00434577) were included in this study. 62 of these subjects further received 1 or 2 additional doses of HZ/su vaccine in the revaccination phase of this study
- Primary Outcome Measures
Name Time Method Frequencies of gE (Glycoprotein)-Specific Cluster of Differentiation (CD4) (2+) T-cells. At Month 120 post first dose of initial vaccination course in study Zoster-003 (NCT00434577). gE specific CD4 (2+)T-cells expressing at least 2 activation markers among IFN-γ, IL-2, TNF-α and CD40L were determined by means of ICS and expressed in T-cells/million cells.
Anti-glycoprotein (gE) Specific Antibody (Ab) Concentrations At Month 120 post first dose of initial vaccination course in study Zoster-003 (NCT00434577). Anti-gE Ab concentrations were determined by ELISA, presented as GMCs and expressed in mIU/mL.
- Secondary Outcome Measures
Name Time Method Anti-glycoprotein (gE) Specific Antibody (Ab) Concentrations by Each Age Category At Months 108 and 120 post first dose of initial vaccination course in study Zoster-003 (NCT00434577). Anti-gE Ab concentrations as determined by ELISA by each age category (60-69 years of age \[YOA\] and ≥70 YOA at the time of initial vaccination).Antibody concentrations were presented as GMCs and expressed in mIU/mL.
Frequencies of Antigen-specific CD4 (2+) T-cells by Each Age Category At Months 108 and 120 post first dose of initial vaccination course in study Zoster-003 (NCT00434577). Antigen specific CD4 (2+) T-cells as determined by means of ICS and expressed in T-cells/million cells, by each age category (60-69 YOA and ≥ 70 YOA at the time of initial vaccination).
