Study Design

In two placebo-controlled, observer-blind, Phase III trials conducted in 18 countries, subjects ≥50 years old (ZOE-50, n=15,405) and subjects ≥70 years old (ZOE-70, n=13,900) were randomized 1:1 to receive two doses (0 and 2 months) of either SHINGRIX or placebo (N=29,305).1

Modified Total Vaccinated Cohort (mTVC): The primary efficacy analysis included all subjects randomized in the study who received a second dose of the vaccine and did not develop a confirmed case of shingles within one month after the second dose.1

Primary endpoints:1

  • ZOE-50: to evaluate the efficacy of SHINGRIX vs. placebo in reducing the risk of shingles in subjects ≥50 years old
  • ZOE-70: to evaluate the efficacy of SHINGRIX vs. placebo in reducing the risk of shingles in subjects ≥70 years old
  • The pooled analysis of ZOE-50 and ZOE-70: to evaluate the efficacy of the vaccine vs. placebo in reducing the risk of shingles and the incidence of PHN in the overall population of subjects ≥70 years old from both studies

Secondary endpoint:3

  • To evaluate the safety and reactogenicity of the vaccine

PHN = postherpetic neuralgia.
