E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate VE in the prevention of HZ compared to placebo in adults >= 50 YOA, as measured by the reduction in HZ risk. |
|
E.2.2 | Secondary objectives of the trial |
•To evaluate VE in the prevention of HZ compared to placebo, by age cohort, as measured by the reduction in HZ risk; •To evaluate VE in the prevention of overall (Postherpetic Neuralgia) PHN compared to placebo in subjects ≥ 50 YOA and by age cohort; •To evaluate VE in reducing the total duration of severe ‘worst’ HZ-associated pain over the entire pain reporting period compared to placebo in subjects ≥ 50 YOA and by age cohort, with confirmed HZ; •To evaluate VE in the reduction of overall and HZ-related mortality and hospitalizations compared to placebo in subjects of ≥ 50 YOA and by age cohort; • To evaluate VE in the reduction in incidence of HZ-associated complications compared to placebo in subjects ≥ 50 YOA and by age cohort, with confirmed HZ; • To evaluate VE in the reduction in use of pain medications compared to placebo in subjects ≥ 50 YOA and by age cohort, with confirmed HZ; •To evaluate vaccine safety and reactogenicity. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Subjects who the investigator believes will comply with the requirements of the protocol (e.g. completion of the diary cards/questionnaires, return for follow-up visits, have regular contact to allow evaluation during the study); Written informed consent obtained from the subject; A male or female aged 50 years or older at the time of the first vaccination; Female subjects of non-childbearing potential may be enrolled in the study; For this study population, non-childbearing potential is defined as current tubal ligation, hysterectomy, ovariectomy or post-menopause. OR Female subjects of childbearing potential may be enrolled in the study, if the subject has practiced adequate contraception for 30 days prior to vaccination, and has a negative urine pregnancy test on the day of vaccination, and has agreed to continue adequate contraception during the entire treatment period and for 2 months after completion of the vaccination series. |
|
E.4 | Principal exclusion criteria |
Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine within 30 days preceding the first dose of study vaccine, or planned use during the study period; Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational product (pharmaceutical product or device); Any confirmed or suspected immunosuppressive or immunodeficient condition resulting from disease (e.g., malignancy, HIV infection) or immunosuppressive/cytotoxic therapy (e.g., medications used during cancer chemotherapy, organ transplantation or to treat autoimmune disorders); History of HZ; Previous vaccination against varicella or HZ (either registered product or participation in a previous vaccine study, and including previous vaccination with childhood varicella vaccine); History of allergic disease or reactions likely to be exacerbated by any component of the vaccine. Additionally, consider allergic reactions to other material or equipment related to study participation (such as materials that may possibly contain latex -gloves, syringes, etc). Please note, the vaccine and vials in this study do not contain latex; Significant underlying illness that in the opinion of the investigator would be expected to prevent completion of the study (e.g., life-threatening disease likely to limit survival to less than 4 years); Receipt of immunoglobulins and/or any blood products within the 90 days preceding the first dose of study vaccine or planned administration during the study period; Administration or planned administration of any other immunizations within 30 days before the first or second study vaccination or scheduled within 30 days after study vaccination. However, licensed non-replicating vaccines (i.e., inactivated and subunit vaccines, including inactivated and subunit influenza vaccines, with or without adjuvant for seasonal or pandemic flu) may be administered up to 8 days prior to each dose and/or at least 14 days after any dose of study vaccine; Any other condition (e.g., extensive psoriasis, chronic pain syndrome, cognitive impairment, severe hearing loss) that, in the opinion of the investigator, might interfere with the evaluations required by the study; Acute disease and/or fever at the time of enrolment; Fever is defined as temperature ≥ 37.5�C (99.5�F) on oral, axillary or tympanic setting, or ≥ 38.0�C (100.4�F) on rectal setting. The preferred route for recording temperature in this study will be oral. Subjects with a minor illness (such as mild diarrhoea, mild upper respiratory infection) without fever may, be enrolled at the discretion of the investigator. Chronic administration (defined as > consecutive 15 days) of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose. For corticosteroids, this will mean prednisone < 20 mg/day, or equivalent, is allowed. Inhaled and topical steroids are allowed.•Pregnant or lactating female; •Female planning to become pregnant or planning to discontinue contraceptive precautions (if of childbearing potential). |
