Treatment and study plan

RZV

Biological

2 doses of RZV in 0, 2 months schedule, administered intramuscularly in the deltoid region of the non-dominant arm

Placebo

Drug

2 doses of placebo in 0, 2 months schedule, administered intramuscularly in the deltoid region of the non-dominant arm

Primary outcomes

  1. Incidence Rate of Confirmed Herpes Zoster (HZ) Cases

    Time frame: From Month 3 (30 days after the second vaccination) up to study end (duration of approximately 2 years)

    A suspected case of HZ was defined as a new unilateral rash accompanied by pain (broadly defined to include allodynia, pruritus or other sensations) and no alternative diagnosis. A confirmed case of HZ was diagnosed by Polymerase Chain Reaction (PCR) or by the HZ Ascertainment Committee (HZAC) determination. The incidence rate (n/T) of confirmed HZ cases, expressed in terms of 1000 person-years rate, was calculated as the number of participants reporting at least one confirmed HZ case (n) in a group, over the sum of follow-up period expressed in years (T) in the same group, and multiplied by 1000.

Secondary outcomes

  1. Incidence Rate of Confirmed HZ Cases, by Age Category

    Time frame: From Month 3 (30 days after the second vaccination) up to study end (duration of approximately 2 years)

    A suspected case of HZ was defined as a new unilateral rash accompanied by pain (broadly defined to include allodynia, pruritus or other sensations) and no alternative diagnosis. A confirmed case of HZ was diagnosed by PCR or by the HZAC determination. The incidence rate (n/T) of confirmed HZ cases, expressed in terms of 1000 person-years rate, was calculated as the number of participants reporting at least one confirmed HZ case (n) in a group, over the sum of follow-up period expressed in years (T) in the same group, and multiplied by 1000. The age categories assessed were 50-69 and greater than or equal to (>=) 70 years of age (YOA).

    Time frame: Within 7 days after each vaccination (occurring at Day 1 and Month 2)

    Assessed solicited local AEs included erythema, pain and swelling at injection site. The intensity of a solicited local AE was scored at GSK by using GSK's standard grading scale as follows: Any AE = occurrence of the event regardless of intensity grade. At least Grade 3 AE = occurrence of an at least Grade 3 or Grade 4 event (Grade 4 defined for some solicited AEs collected in the study as required by Chinese grading scale). Maximum of Grade 3 and 4 was considered as Grade 3 for all applicable solicited symptoms in GSK standard grading table. AE resulting in a medically attended visit = event for which the participant received medical attention defined as hospitalization, or an otherwise unscheduled visit to or from medical personnel for any reason, including emergency room visits.

    Assessed solicited general AEs included fatigue, fever, gastrointestinal symptoms (nausea, vomiting and/or abdominal pain) headache, myalgia, and shivering. The intensity of a solicited general AE was scored at GSK by using GSK's standard grading scale as follows: Any AE = occurrence of the event regardless of intensity grade or relation to vaccination. At least Grade 3 AE = occurrence of an at least Grade 3 or Grade 4 event (Grade 4 defined for some solicited AEs collected in the study as required by Chinese grading scale). Maximum of Grade 3 and 4 was considered as Grade 3 for all applicable solicited symptoms in GSK standard grading table. Related AE = event assessed by the investigator as related to vaccination. AE resulting in a medically attended visit = event for which the participant received medical attention defined as hospitalization, or an otherwise unscheduled visit to or from medical personnel for any reason, including emergency room visits.
