Immunogenicity and Safety Study of ZOSTAVAX Administered by Intramuscular or Subcutaneous Route to Participants Aged From 50 Years Old (V211-045)

December 20, 2018 updated by: Merck Sharp & Dohme LLC

An Open-label, Randomised, Comparative, Multicentre Study of the Immunogenicity and Safety of ZOSTAVAX When Administered by Intramuscular Route or Subcutaneous Route to Subjects of 50 Years of Age and Older

PRIMARY OBJECTIVES

Two co-primary objectives are:

  • To demonstrate that the immunogenicity of ZOSTAVAX administered by intramuscular route (IM) is non-inferior to ZOSTAVAX administered by subcutaneous route (SC)
  • To demonstrate that ZOSTAVAX administered by IM route induces an acceptable fold-rise of varicella zoster virus (VZV) antibody titre from pre to 4-week post-vaccination

SECONDARY OBJECTIVES

Immunogenicity objectives

  • To evaluate the immunogenicity as measured by VZV antibody titre at 4 weeks following ZOSTAVAX administered by IM or SC route
  • To evaluate the immune response as measured by a second assay, the VZV Interferon gamma Enzyme-linked immunospot (ELISPOT) at 4 weeks following ZOSTAVAX administered by IM or SC route

Safety objective

- To describe the safety profile of ZOSTAVAX administered by IM or SC route

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Geometric Mean Titre (GMT) of Varicella Zoster Virus (VZV) Antibodies 4 Weeks Post-vaccination
Time Frame: 4 week post-vaccination
Blood samples taken at 4 weeks post vaccination to determine the geometric mean titre (GMT) of VZV antibodies via Glycoprotein Enzyme Linked Immunosorbent Assay (gpELISA).
4 week post-vaccination
Geometric Mean Fold Rise (GMFR) in VZV Antibody Titre: IM Route
Time Frame: Pre-vaccination (Day 0) and 4 week post-vaccination
Blood sample taken at predose (Day 0) and 4 weeks post vaccination to determine the geometric mean titre (GMT) of VZV antibodies via gpELISA. The GMFR was calculated as GMT Post-dose/GMT Pre-vaccination
Pre-vaccination (Day 0) and 4 week post-vaccination

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Geometric Mean Fold Rise (GMFR) in VZV Antibody Titre: SC Route
Time Frame: Pre-vaccination (Day 0) and 4 week post-vaccination
Blood sample taken at predose (Day 0) and 4 weeks post vaccination to determine the geometric mean titre (GMT) of VZV antibodies via gpELISA. The GMFR was calculated as GMT Post-vaccination/GMT Pre-vaccination
Pre-vaccination (Day 0) and 4 week post-vaccination
Geometric Mean Count (GMCs) of VZV Interferon Gamma ((IFN-γ) Enzyme-Linked ImmunoSpot (ELISPOT) Antibodies
Time Frame: 4 week post-vaccination
Blood samples taken 4 weeks post-vaccination to determine the IFN-γ ELISPOT GMC's. Results were reported as ELISPOT count/10^6 Peripheral Blood Mononuclear Cells (PBMC)
4 week post-vaccination
Geometric Mean Fold Rise (GMFR) of IFN-γ ELISPOT Antibodies
Time Frame: Pre-vaccination (Day 0) and 4 week post-vaccination
Blood samples taken pre-vaccination and 4 weeks post-vaccination to determine the IFN-γ ELISPOT GMFR.
Pre-vaccination (Day 0) and 4 week post-vaccination
Percentage of Participants Who Report at Least 1 Injection-site Adverse Reaction
Time Frame: up to 28 days after vaccination
Participants entered data into daily diary card regarding previously identified possible injection site reactions of erythema, injection site swelling or injection site pain for 1st 4 days post-vaccination. Additionally, injection site reactions not prompted on diary card (unsolicited) were collected up 28 days post-vaccination. All injection site reactions (solicited or unsolicited) were recorded.
up to 28 days after vaccination
Percentage of Participants Who Report at Least 1 Systemic Adverse Event
Time Frame: up to Day 28 after vaccination
An adverse event (AE) was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study drug, whether or not considered related to the use of the product. Adverse events that were considered systemic (not localized) were summarized. These events included rashes of interest: i.e. Varicella, Varicella-like rashes, Herpes zoster or shingles and Herpes zoster-like rashes and other systemic adverse events.
up to Day 28 after vaccination
Percentage of Participants Who Report at Least 1 Serious Adverse Event
Time Frame: up to 35 days after vaccination
A serious adverse event (SAE) is any adverse event that results in death, is life threatening, results in a persistent or significant disability/incapacity, results in hospitalization or prolongs an existing hospitalization, is a congenital anomaly/birth defect, is a cancer, is an overdose, or is considered an "other important medical event" based on medical judgement. The percentage of participants who reported an SAE within 35 days of vaccination were recorded.
