Brief 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%.

Condition or disease Intervention/treatment Phase
Herpes Zoster Biological: V212 Biological: Matching placebo Phase 3

Detailed Description:
Study participants were randomized to receive one of 3 consistency lots of V212, a high antigen lot of V212, or placebo. To comply with regulatory requests, results for all lots of V212 were combined for the primary and secondary efficacy and safety evaluations (Protocol Amendment 2); all planned comparisons between the V212 lots were exploratory and are not included in this disclosure. Further, by regulatory request, the V212 High Antigen Lot was not included in the efficacy analyses for concerns that its inclusion would inflate the efficacy estimates (Protocol Amendment 4).

Primary Outcome Measures :
  1. Incidence of Confirmed Herpes-Zoster [ Time Frame: Up to approximately 5 years ]
    Clinical criteria for suspected Herpes-Zoster (HZ) cases were the development of a papular or vesicular rash with a dermatomal or generalized distribution, or in the absence of a rash, clinical suspicion of VZV infection with or without the detection of VZV in diagnostic specimens from blood, cerebrospinal fluid, lung, liver, or other organ. All suspected cases of HZ were subjected to adjudication by the Clinical Adjudication Committee (CAC). Case confirmation was based on skin lesion polymerase chain reaction, if available, or by adjudication of the clinical case description by the CAC, conducted according to the CAC Standard Operations Procedure.

  2. Percentage of Participants With One or More Serious Adverse Events [ Time Frame: Up to 28 days after vaccination 4 (up to 118 days) ]
    An adverse event (AE) is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the sponsor's product, whether or not considered related to the use of the product. A serious adverse event (SAE) is an AE that results in death, is life threatening, results in a persistent or significant disability or incapacity, results in or prolongs an existing hospitalization, is a congenital anomaly or birth defect, is a cancer, is an overdose, or is another important medical event.


Secondary Outcome Measures :
  1. Incidence of Moderate to Severe Herpes-Zoster-Associated Pain [ Time Frame: Up to 6 months after onset of HZ (up to approximately 5 years) ]
    Moderate to severe HZ-associated pain was defined as 2 or more occurrences of a score 3 or greater (0-to-10 scale, where 0 is no pain and 10 is pain as bad as you can imagine) on the Zoster Brief Pain Inventory (ZBPI) at any time from HZ onset through the end of the 6 month HZ-follow-up period.

  2. Incidence of Herpes-Zoster Complications [ Time Frame: Up to 6 months after onset of HZ (up to approximately 5 years) ]
    The composite efficacy endpoint of the incidence of HZ complications was 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.

  3. Incidence of Postherpetic Neuralgia [ Time Frame: Up to 6 months after the onset of HZ rash (up to approximately 5 years) ]
    Postherpetic Neuralgia (PHN) was defined as pain in the area of the HZ rash with pain in the last 24 hours scored as 3 or greater (on a 0 to 10 scale, where 0 is no pain and 10 is pain as bad as you can imagine) on the ZBPI that persists or appears greater than or equal to 90 days after HZ rash onset.


Other Outcome Measures:
  1. Percentage of Participants With Study Medication Withdrawn Due to an Adverse Event [ Time Frame: Up to 28 days after vaccination 4 (up to 118 days) ]
    An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the sponsor's product, whether or not considered related to the use of the product. A serious adverse event (SAE) is an AE that results in death, is life threatening, results in a persistent or significant disability or incapacity, results in or prolongs an existing hospitalization, is a congenital anomaly or birth defect, is a cancer, is an overdose, or is another important medical event.
