Immunogenicity and Safety Study of GSK Biologicals' Herpes Zoster Vaccine GSK1437173A When Co-administered With Prevenar13 in Adults Aged 50 Years and Older

GlaxoSmithKline913 enrolled

Overview

The purpose of this study is to assess immunogenicity and safety of GSK Biologicals' HZ vaccine when its first dose is co-administered with a pneumococcal polysaccharide conjugate vaccine (Prevenar13) in adults aged ≥50 YOA, as compared to the control group where the two HZ/su doses are administered subsequent to Prevenar13.

Following the initial approval of the GlaxoSmithKline (GSK) Biologicals' HZ/su vaccine, the protocol was amended to indicate that the trademark is Shingrix. In addition, the term "candidate" vaccine has been replaced by "study" vaccine throughout the protocol.

Exclusion Criteria: * Use of any investigational or non-registered product other than the study vaccines during the period starting 30 days before the first dose of study vaccines (Day -30 to Day 1), or planned use during the study period. * Any medical condition that in the judgment of the investigator would make intramuscular (IM) injection unsafe. * Use or anticipated use of immunosuppressants or other immune-modifying drugs during the period starting six months prior to study start and during the whole study period. This includes chronic administration of corticosteroids (\>14 consecutive days of prednisone at a dose of ≥20 mg/day \[or equivalent\]), long-acting immune modifying agents or immunosuppressive/cytotoxic therapy. Inhaled, topical and intra-articular corticosteroids are allowed. * Administration or planned administration of a vaccine not foreseen by the study protocol in the period starting 30 days before the first dose and ending 30 days after the last dose of study vaccine administration. This includes any type of vaccine such as (but not limited to) live, inactivated and subunit vaccines. * Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational vaccine/product. * Previous and/or planned administration of an HZ or VZV vaccine other than the study vaccine during the study period. * History of HZ. * History of documented pneumococcal infection within 5 previous years. * Prior receipt of any pneumococcal vaccine or planned use during the study period, other than the study vaccines. * Any confirmed or suspected immunosuppressive or immunodeficient condition resulting from disease or immunosuppressive/cytotoxic therapy. * History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccines. * Acute disease and/or fever at the time of enrollment. * Fever is defined as temperature ≥ 38.0°C/100.4°F. The preferred location for measuring temperature in this study will be the oral cavity. * Subjects with a minor illness without fever may, be enrolled at the discretion of the investigator. * Administration of immunoglobulins and/or any blood products during the period starting 3 months before the first dose of study vaccine or planned administration during the study period. * Pregnant or lactating female. * Female planning to become pregnant or planning to discontinue contraceptive precautions before 2 months after the last dose of study vaccine. * Any person with cerebrospinal fluid (CSF) leaks, cochlear implants, chronic renal failure, nephrotic syndrome and functional or anatomic asplenia. * Any medical condition that in the judgment of the investigator would prevent the subject from participating in the study.

Outcomes

Primary Outcomes

Percentage of Subjects With a Vaccine Response for Anti-glycoprotein E (Anti-gE) in Co-Ad Group

Vaccine response rate (VRR) for Varicella Zoster Virus (VZV) anti-glycoprotein E (gE) humoral immunogenicity was determined by Enzyme Limked Immunosorbent Assay (ELISA). The VRR for anti-gE is defined as the percentage of subjects who had at least: a 4-fold increase in the anti-gE antibodies concentration as compared to the pre-vaccination anti-gE antibodies concentration, for subjects who are seropositive at baseline, or, a 4-fold increase in the anti-gE antibodies concentration as compared to the anti-gE antibodies cut-off value for seropositivity, for subjects who are seronegative at baseline.

Time frame: One month post-dose 2 (Month 3)

Anti-gE Antibody Concentrations

Anti-gE antibody concentrations in terms of Geometric Mean concentrations (GMC) were determined by ELISA and expressed as milli-international units per milliliter (mIU/mL)

Time frame: One month post-dose 2 (at Month 3 for the Co-Ad and Month 5 for the Control group).

Anti-pneumococcal Antibody Titers

Anti-pneumococcal antibody titers for the 13 serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F and 23F) were determined by Multiplex Opsonophagocytosis Assay (MOPA)

Time frame: At one month post-dose 1 (Month 1)

Adjusted Geometric Mean Concentrations (GMCs) for Anti-gE Antibody

Anti-gE antibody concentrations (GMCs) adjusted for age and baseline concentrations were determined using Analysis Of Covariance (ANCOVA) model. Adjusted GMCs were expressed in milli-international units per milliliter (mIU/mL)

Time frame: One month post-dose 2 (at Month 3 for the Co-Ad and Month 5 for the Control group).

Adjusted Geometric Mean Titers (GMTs) of Anti-pneumococcal Antibodies

Geometric mean antibody (anti-pneumococcal antibodies: 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F and 23F) titers adjusted for age and baseline concentration were determined using ANCOVA model.

Secondary Outcomes

Number of Subjects With Any and Grade 3 Solicited Local Symptoms by Vaccine and Dose

Assessed solicited local symptoms were pain, erythema and swelling. Any = occurrence of the symptom regardless of intensity grade. Grade 3 pain = pain that prevented normal activity.
