Overview
Brief Summary
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.

Outcomes
Primary Outcomes
Percentage of Participants With One or More Serious Adverse Events
Time Frame: Up to 28 days after vaccination 4 (up to approximately 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.
Incidence of Confirmed Herpes-Zoster
Time Frame: Up to approximately 5 years
Clinical criteria for suspected 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.
Secondary Outcomes
- Incidence of Postherpetic Neuralgia(Up to 6 months after onset of HZ (up to approximately 5 years))
- Incidence of Moderate to Severe Herpes-Zoster-Associated Pain(Up to 6 months after onset of HZ (up to approximately 5 years))
- Incidence of Herpes-Zoster Complications(Up to 6 months after onset of HZ (up to approximately 5 years))
