Study to Assess the Immune Response and the Safety Profile of a High-Dose Quadrivalent Influenza Vaccine (QIV-HD) Compared to a Standard-Dose Quadrivalent Influenza Vaccine (QIV-SD) in Japanese Adults 60 Years of Age and Older
Immunogenicity and Safety of High-Dose Quadrivalent Influenza Vaccine (SP0178) Administered by Intramuscular Route Versus Standard-Dose Quadrivalent Influenza Vaccine by Subcutaneous Route in Subjects 60 Years of Age and Older in Japan
Primary Objective:
To demonstrate that QIV-HD induced an immune response (as assessed by hemagglutination inhibition [HAI] geometric mean titers [GMTs] and seroconversion rates) that was superior to responses induced by QIV-SD for the 4 virus strains at 28 days post-vaccination in all participants.
Secondary Objective:
- To describe the immune response induced by QIV-HD and QIV-SD by HAI measurement method in all participants.
- To describe the safety profile of all participants in each study group.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Geometric Mean Titers (GMTs) of Influenza Vaccine Antibodies at Day 28
Time Frame: Day 28 (post-vaccination)
|
GMTs of anti-influenza antibodies were measured using hemagglutination inhibition (HAI) assay for 4 influenza virus strains: A/H1N1, A/H3N2-like, B/Victoria-like, and B/Yamagata.
Titers were expressed in terms of 1/dilution.
|
Day 28 (post-vaccination)
|
Percentage of Participants Achieving Seroconversion Against Influenza Virus Antigens: Superiority Analysis
Time Frame: Day 28 (post-vaccination)
|
Anti-influenza antibodies were measured by HAI assay for 4 influenza virus strains: A/H1N1, A/H3N2-like, B/Victoria-like, and B/Yamagata.
Seroconversion was defined as either a pre-vaccination HAI titer less than (<) 10 (1/dilution) and a post-vaccination titer >=40 (1/dilution) or a pre-vaccination titer >=10 (1/dilution) and a >= four-fold increase in post-vaccination titer at Day 28.

An AE was any untoward medical occurrence in a patient or in a clinical investigation participant administered a medicinal product and which did not necessarily have a casual relationship with the treatment.
An unsolicited AE was an observed AE that did not fulfill the conditions prelisted in the case report book (CRB) in terms of diagnosis and/or onset window post-vaccination.
All participants were observed for 30 minutes after vaccination, and any unsolicited AEs that occurred during that time were recorded as immediate unsolicited AEs in the CRB.

A solicited reaction was an expected adverse reaction (sign or symptom) observed and reported under the conditions (nature and onset) prelisted (i.e., solicited) in the CRB and considered as related to the product administered.
Solicited injection site reactions included injection site pain, injection site erythema, injection site swelling, injection site induration, and injection site bruising.
