This is a randomized, double-blind, placebo-controlled study to assess the safety and tolerability of V212 when administered to adults with solid tumor malignancy (STM) or hematologic malignancy (HM) and to determine whether V212 reduces the incidence of herpes zoster (HZ) in adults with STM or HM, as compared to placebo.
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
|Official Title:||A Phase III Randomized, Placebo-Controlled, Clinical Trial to Study the Safety and Efficacy of V212 in Adult Patients With Solid Tumor or Hematologic Malignancy|

Primary Outcome Measures:
- The number of HZ cases per 1000 person-years of follow-up in the STM Population [ Time Frame: From study enrollment up to approximately 5 years ]
- The number of participants experiencing serious adverse events in the STM Population [ Time Frame: From vaccination day 1 through 28 days post vaccination dose 4 ]
Secondary Outcome Measures:
- Incidence of moderate to severe HZ-associated pain in the STM Population [ Time Frame: From HZ onset through the end of the 6 month HZ-follow-up period ]Moderate to severe HZ-associated pain is 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 in the STM Population [ Time Frame: Approximately 5 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) in the STM Population [ Time Frame: From HZ onset through the end of the 6 month HZ-follow-up period ]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 >= 90 days after the onset of the HZ rash.
