Clinical Trial Summary

This randomized, modified double-blind, active-controlled, multi-center trial assessed the safety and immunogenicity of the high-dose quadrivalent influenza vaccine (QIV-HD) compared to either the licensed or investigational high-dose trivalent influenza vaccine (TIV-HD) in adults.

Description:

This randomized, modified double-blind, active-controlled, multi-center trial was conducted in healthy adults (greater than and equal to [>=] 65 years) to assess the safety and immunogenicity (geometric mean titers and seroconversion for the 4 virus strains at 28 days post vaccination) of the QIV-HD compared to one of the TIV-HDs containing either the B strain from the primary lineage (TIV-HD1; licensed vaccine [Fluzone® High-Dose] for the 2017-2018 Northern Hemisphere [NH] influenza season) or the B strain from the alternate lineage (TIV-HD2, investigational TIV-HD containing an alternate B strain).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Geometric Mean Titers (GMTs) of Influenza Antibodies Following Vaccination With Either a High-Dose Quadrivalent Influenza Vaccine or High-Dose Trivalent Influenza Vaccine	GMTs of anti-influenza antibodies were measured using an hemagglutination inhibition (HAI) assay for 4 strains: A/H1N1, A/H3N2, B Victoria lineage (B1), and B Yamagata lineage (B2). For each A strain, the comparison was made with the pooled TIV-HD groups. For each B strain, the comparison was made with the TIV-HD group containing the corresponding B strain. TIV-HD 1 did not contain B2 strain; TIV-HD2 did not contain B1 strain.	Day 28 post-vaccination
Primary	Percentage of Participants Achieving Seroconversion Against Antigens Following Vaccination With Either a High-Dose Quadrivalent Influenza Vaccine or High-Dose Trivalent Influenza Vaccine	Anti-influenza antibodies were measured using an HAI assay for 4 strains: A/H1N1, A/H3N2, B Victoria lineage (B1), and B Yamagata lineage (B2). Seroconversion was defined as either a HAI titer less than (<) 10 (1/dilution) at Day 0 and post-injection titer greater than or equal to (>=) 40 (1/dilution) at Day 28, or HAI titer >=10 (1/dilution) at Day 0 and a >=4-fold increase in HAI titer (1/dilution) at Day 28. For each A strain, the comparison was made with the pooled TIV-HD groups. For each B strain, the comparison was made with the TIV-HD group containing the corresponding B strain.

Seroprotection was defined as a HAI titer >=40 (1/dilution) at Day 0 and Day 28.	Day 0 (pre-vaccination) and Day 28 post-vaccination
Secondary	Geometric Mean Titers of Influenza Antibodies (Seroneutralization [SN] Assay) Following Vaccination With Either a High-Dose Quadrivalent Influenza Vaccine or High-Dose Trivalent Influenza Vaccine	GMTs of anti-influenza antibodies were measured using SN assay for 4 strains: A/H1N1 (A1), A/H3N2 (A2), B Victoria lineage (B1), and B Yamagata lineage (B2).	Day 0 (pre-vaccination) and Day 28 post-vaccination
Secondary	GMTRs of Influenza Antibodies (SN Assay) Following Vaccination With Either a High-Dose Quadrivalent Influenza Vaccine or High-Dose Trivalent Influenza Vaccine	GMTRs of anti-influenza antibodies were measured using SN assay for 4 strains: A/H1N1 (A1), A/H3N2 (A2), B Victoria lineage (B1), and B Yamagata lineage (B2). GMTRs were calculated as the ratio of GMTs post vaccination and pre-vaccination.	Day 0 (pre-vaccination) and Day 28 post-vaccination
Secondary	Number of Participants With Neutralization Antibody Titers at Day 0 and Day 28	Neutralizing Antibody titer was measured for each influenza strain with the SN method for 4 strains: A/H1N1, A/H3N2, B Victoria lineage (B1), and B Yamagata lineage (B2). Neutralizing antibody was defined as titers >=20 (1/dilution), >=40 (1/dilution), >=80 (1/dilution) at Day 0 and Day 28.	Day 0, Day 28
Secondary	Number of Participants With Two-Fold and Four-Fold Increase in Neutralization Antibody Titer at Day 28	Neutralizing Antibody titer was measured for each influenza strain with the SN method for 4 strains: A/H1N1, A/H3N2, B Victoria lineage (B1), and B Yamagata lineage (B2). 2-fold and 4-fold rise was defined as the computed value = post-vaccination computed value / baseline computed value.

Secondary	Number of Participants With Immediate Adverse Event (AEs)	Participants were observed for 30 minutes after vaccination, and any unsolicited systemic AEs occurring during that time was recorded as immediate unsolicited systemic AEs (AEs that were related to the investigational product) in the case report book (CRB). Unsolicited AE was an observed AE that did not fulfill the conditions prelisted in the CRB in terms of symptom and/ or onset post-vaccination. Unsolicited AEs included both serious and non-serious unsolicited AEs. A serious adverse event was any untoward medical occurrence that at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, or was an important medical event.	Within 30 minutes after vaccination
Secondary	Number of Participant With Unsolicited Adverse Event (AE)	An unsolicited AE was an observed AE that did not fulfill the conditions prelisted in the CRB in terms of symptom and/or onset post-vaccination. Unsolicited AEs included both serious and non-serious unsolicited AEs. A serious adverse event was any untoward medical occurrence that at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, or was an important medical event.	Within 28 days after vaccination
Secondary	Number of Participant With Serious Adverse Event	An serious adverse event was any untoward medical occurrence that at any dose results in death, was life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity,is a congenital anomaly/birth defect, or was an important medical event.
