Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: A Phase III, Double-Blind, Randomized, Placebo-Controlled, Multicenter Clinical Trial to Study the Safety, Tolerability, Efficacy, and Immunogenicity of V212 in Recipients of Autologous Hematopoietic Cell Transplants (HCTs)

Primary Outcome Measures:
  • Incidence of herpes zoster (HZ) [ Time Frame: Approximately 3 years ]
    Incidence is defined as the number of HZ cases per 1000 person-years of follow-up from study enrollment to the end of study.

Secondary Outcome Measures:
  • Incidence of moderate to severe HZ-associated pain [ Time Frame: From HZ onset through the end of the 6 month HZ-follow-up period ]
    Moderate to severe HZ-associated pain (defined as 2 or more occurrences of a score of 3 or greater (0-to-10 scale) on the Zoster Brief Pain Inventory [ZBPI]),

  • Incidence of HZ complications [ Time Frame: Approximately 3 years ]
    HZ complications defined as the occurrence of any of the following during the study: hospitalization or prolongation of hospitalization due to HZ, disseminated HZ (including disseminated HZ rash or VZV viremia), visceral HZ, ophthalmic HZ, neurological impairment due to HZ, or administration of intravenous acyclovir therapy for treatment of HZ.

  • Incidence of postherpetic neuralgia (PHN) [ Time Frame: Onset of HZ rash up to 6-month follow-up ]
    Postherpetic neuralgia (PHN) is defined as a worst pain score [in the last 24 hours] of 3 or greater [0-to-10 scale] on the Zoster Brief Pain Inventory (ZBPI) that persists or appears greater than or equal to 90 days after the onset of the HZ rash
