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)

In Brief

A Phase 3 clinical trial evaluating V212 and Matching placebo for Herpes Zoster. Completed, enrolled 1,257 participants.

Detailed Summary

This is a randomized, double-blind, placebo-controlled study to assess the safety and efficacy of inactivated VZV vaccine for the prevention of HZ and HZ-related complications in adult recipients of autologous hematopoietic cell transplants (HCTs). The primary hypothesis is that vaccination with V212 vaccine will reduce the incidence of herpes zoster (HZ) compared to placebo when administered to recipients of HCT. The statistical criterion for success requires that the lower bound of the 95% confidence interval for the estimated vaccine efficacy in the V212 recipients (excluding the high-antigen lot) compared with that in the placebo recipients is \>25%.
