A Study to Evaluate the Safety and Efficacy of Inactivated Varicella-zoster Vaccine (VZV) as a Preventative Treatment for Herpes Zoster (HZ) and HZ-related Complications in Adult Participants With Solid Tumor or Hematologic Malignancy (V212-011)

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) receiving chemotherapy and to assess the impact of V212 on the development of herpes zoster (HZ) in adults with STM receiving chemotherapy. The primary hypothesis is that vaccination with V212 will reduce the incidence of HZ compared with placebo in adults with STM (lower bound of the 97.5% {one-sided α=0.0125} confidence interval [CI] for the estimated vaccine efficacy in adults with STM be >25%).

Participants with hematologic malignancy (HM) were also enrolled and were to be originally included in the primary and secondary objectives and analyses. After an interim analysis demonstrated clear evidence of futility of V212 in the HM population, enrollment of this population was stopped and all HM-related objectives and analyses were made exploratory and are not reported in this record.
