149. Immunogenicity, Safety, and Post-hoc Efficacy Assessment of the Adjuvanted Recombinant Zoster Vaccine in Adults with Hematologic Malignancies: A Phase 3, Randomized Clinical Trial

ABSTRACT: Abstract

Background

Patients with hematologic malignancies treated with anticancer immunosuppressive therapies (ITs) are at increased risk of herpes zoster (HZ). In a previous report of this phase 3, observer-blind, multicenter trial (NCT01767467), the adjuvanted recombinant zoster vaccine (RZV) was shown to be immunogenic and well-tolerated in ≥18 years of age patients with hematologic malignancies who completed or were undergoing anticancer IT.1 Here we report end-of-study results from the same trial.

Methods

Participants were randomized 1:1 to receive 2 doses of RZV or placebo (PL) 1–2 months apart, either ≥10 days before or after a cancer therapy cycle, or 10 days to 6 months after cancer therapy ended. Humoral and cell-mediated immune (CMI) responses were evaluated a
