Trial overview
Official title: A phase 3b, open-label, multi-country, multi-centre, long-term follow-up study of ZOSTER-049 (follow-up of ZOSTER-006/022 studies) to assess the prophylactic efficacy, safety and persistence of immune response of a Herpes Zoster subunit vaccine and assessment of persistence of immune response and safety of 1 or 2 additional doses administered in ZOSTER-049 in 2 subgroups of older adults
Trial description: The purpose of the current ZOSTER-101 long-term follow-up (LTFU) study of ZOSTER-049 (NCT02723773) study, an extension of ZOSTER-006 (NCT01165177) and ZOSTER-022 (NCT01165229) primary studies, is to assess the long-term vaccine efficacy (VE) against Herpes Zoster (HZ) (approximately 11-15 years post primary vaccination in ZOSTER-006/022 studies), persistence of immunogenicity and safety of GSK’s Herpes Zoster subunit (HZ/su) vaccine in older adults. The persistence of immunogenicity and safety of 1 or 2 additional doses (0, 2-month schedule) of HZ/su vaccine administered to a small group of participants in ZOSTER-049 study (approximately 5 years after the initial vaccination in ZOSTER-006/022 studies) will also be assessed.
Primary purpose:
Prevention
Trial design:
Factorial Assignment
Masking:
None (Open Label)
Allocation:
Randomized
Primary outcomes:
Number of participants in LTFU and Control groups with confirmed HZ cases
Timeframe: During the total duration of ZOSTER-101 study (Day 1 through Month 48)
Secondary outcomes:
Number of participants in LTFU and Control groups with confirmed HZ cases
Timeframe: From 1-month post-Dose 2 in the ZOSTER-006/022 studies until the end of the ZOSTER-101 study at Month 48
Anti-glycoprotein E (gE) antibody concentrations
Timeframe: At Day 1, Months 12, 24, 36 and 48 in the ZOSTER-101 study
Frequency of gE-specific Cluster of Differentiation (CD)4+ T-cells secreting at least two activation markers from among IFN-γ, IL-2, TNF-α, CD40L
Timeframe: At Day 1, Months 12, 24, 36 and 48 in the ZOSTER-101 study
Percentage of participants with serious adverse events (SAEs) causally related to the study intervention
Timeframe: During the total duration of the ZOSTER-101 study (Day 1 through Month 48)
Percentage of participants with potential immune-mediated diseases (pIMDs) (serious and non-serious) causally related to the study intervention
Timeframe: During the total duration of the ZOSTER-101 study (Day 1 through Month 48)
Percentage of participants with HZ-related complications of confirmed HZ
Timeframe: During the total duration of the ZOSTER-101 study (Day 1 through Month 48)

- Written or witnessed/thumb printed informed consent obtained from the participant prior to performance of any study-specific procedure.
- Medically stable participants as established by medical history and clinical examination before entering into the study.

- Any clinical condition that, in the opinion of the investigator, might pose additional risk to the participant due to participation in the study. Prior/Concomitant therapy
- Use of any investigational or non-registered product (drug, vaccine or medical device) for the treatment of HZ or Varicella Zoster Virus (VZV) infection at the time of enrolment or their planned use during the study period.
- Previous vaccination against VZV or HZ and/or planned administration during the study of a VZV or HZ vaccine (including an investigational or non-registered vaccine other than HZ/su administered in studies ZOSTER-006/022 or ZOSTER-049). Prior/Concurrent clinical study experience
- Concurrently participating in another clinical study, at any time during the study period, in which the participant has been or will be exposed to an investigational or a non-investigational intervention (drug/invasive medical device) for the prevention and/or treatment of HZ or VZV and which may have a possible activity against VZV.
