Immunogenicity and Safety of a Quadrivalent Influenza Vaccine Given by Intramuscular Route in Subjects Aged 18 to 60 Years

Phase 3

Completed

Conditions: Influenza

Interventions: Biological: Quadrivalent influenza vaccine (QIV) (split virion, inactivated) Northern Hemisphere (NH) 2015-2016
Biological: Trivalent influenza vaccine (TIV) (split virion, inactivated) NH 2015-2016 formulation

Registration Number: NCT02550197

Lead Sponsor: Sanofi Pasteur, a Sanofi Company

Brief Summary: The aim of the trial is to evaluate immunogenicity and safety of the quadrivalent influenza vaccine (QIV) and the trivalent influenza vaccine (TIV) (split-virion inactivated) Northern Hemisphere (NH) 2015 2016 seasonal formulations, in subjects aged 18 to 60 years in the Republic of Korea for the registration of the QIV by the Ministry of Food and Drug Safety.

Objectives:

* To evaluate the immunogenicity of QIV and TIV (split-virion, inactivated) NH 2015-2016 seasonal formulations. The compliance, in terms of immunogenicity, of the QIV NH 2015-2016 formulation, with the requirements of the Committee for Medicinal Products for Human Use (CHMP) Note for Guidance (NfG) CPMP/BWP/214/96 will be assessed.

* To evaluate the safety profile of QIV and TIV (split-virion, inactivated) NH 2015-2016 seasonal formulations

Detailed Description: All subjects will receive one dose of either QIV or TIV on Day 0. They will be monitored for safety and immunogenicity for up to Day 21 post-vaccination.

Participation at the time of study enrollment (or in the 4 weeks preceding the trial vaccination) or planned participation during the present trial period in another clinical trial investigating a vaccine, drug, medical device, or medical procedure
Receipt of any vaccine in the 4 weeks preceding the trial vaccination or planned receipt of any vaccine until the second visit, 3 weeks following the trial vaccination
Vaccination against influenza if administered in the context of a clinical trial or a flu vaccination campaign or self-reported history of influenza infection (influenza-like illness) in the previous 6 months
Receipt of immune globulins, blood or blood-derived products in the past 3 months
Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy, such as anti-cancer chemotherapy or radiation therapy, within the preceding 6 months; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months)
Known history of seropositivity for Human Immunodeficiency Virus (HIV) or Hepatitis C
Known systemic hypersensitivity to eggs, chicken proteins, neomycin, formaldehyde and octoxynol-9, or to any of the vaccine components, or history of a life-threatening reaction to the vaccines used in the study or to a vaccine containing any of the same substances
Known or suspected thrombocytopenia, contraindicating intramuscular vaccination, based on Investigator's judgment
Bleeding disorder, or receipt of anticoagulants in the 3 weeks preceding inclusion, contraindicating intramuscular vaccination, based on Investigator's judgment

Current alcohol abuse or drug addiction
Chronic illness that, in the opinion of the investigator, is at a stage where it might interfere with trial conduct or completion
Moderate or severe acute illness/infection (according to investigator judgment) on the day of vaccination or febrile illness (temperature ≥ 38.0°C). A prospective subject should not be included in the study until the condition has resolved or the febrile event has subsided

TIV Group	Trivalent influenza vaccine (TIV) (split virion, inactivated) NH 2015-2016 formulation	Subjects will receive one dose of the Trivalent influenza vaccine (TIV) (split virion, inactivated) NH 2015-2016 formulation

Primary Outcome Measures

Name	Time	Method
Percentage of Participants Achieving Seroconversion or Significant Increase Against Influenza Antigens After Vaccination With a Quadrivalent Influenza Vaccine Administered Via the Intramuscular Route	Day 21 post-vaccination	Immunogenicity was evaluated using the hemagglutination inhibition (HAI) technique. Seroconversion was defined as titers \< 10 (1/dil) on Day 0 and post-injection titer ≥ 40 (1/dil) on Day 21, and Significant increase was defined as titers ≥ 10 (1/dil) on Day 0 and ≥ 4-fold increase of post-injection titer on Day 21.
Percentage of Participants With Influenza Antibodies Titers < 10 (1/Dil) Before and After Vaccination With a Quadrivalent Influenza Vaccine Administered Via the Intramuscular Route	Day 0 (pre-vaccination) and Day 21 post-vaccination	Immunogenicity was evaluated using the hemagglutination inhibition (HAI) technique.
Percentage of Participants Reporting Solicited Reactions Listed in The Former Committee for Medicinal Products for Human Use Note for Guidance Within 3 Days After Vaccination With a Quadrivalent Influenza Vaccine Administered Via the Intramuscular Route	Day 0 up Day 3 post-vaccination	The solicited reactions evaluated were Injection-site Induration (≥50 mm for at least 4 consecutive days), Injection-site Ecchymosis (injection site bruising), Pyrexia (recorded temperature \>38.0˚C for at least 1 day), Malaise, and Shivering (rigors).
Percentage of Participants Achieving Seroprotection Against Influenza Antigens Before and After Vaccination With a Quadrivalent Influenza Vaccine Administered Via the Intramuscular Route	Day 0 (pre-vaccination) and Day 21 post-vaccination	Immunogenicity was evaluated using the hemagglutination inhibition (HAI) technique. Seroprotection was defined as titers ≥ 40 (1/dil) on Day 0 and Day 21.
Geometric Mean Titer Ratios of Influenza Virus Antibodies After Vaccination With a Quadrivalent Influenza Vaccine Administered Via the Intramuscular Route	Day 0 (pre-vaccination) and Day 21 post-vaccination	Immunogenicity was evaluated using the hemagglutination inhibition (HAI) technique.
Percentage of Participants Reporting Solicited Injection-Site or Systemic Reaction After Vaccination With a Quadrivalent Influenza Vaccine Administered Via the Intramuscular Route	Day 0 up Day 7 post-vaccination	Solicited Injection-site reactions: Pain, Erythema, Swelling, Induration, and Ecchymosis. Solicited Systemic reactions: Fever, Headache, Malaise, Myalgia, and Shivering. Grade 3: Pain, Significant; prevents daily activity; Erythema, Swelling, Induration, and Ecchymosis, \>100 mm. Grade 3 Solicited Systemic reactions: Fever, ≥ 39.0˚C; Headache, Malaise, Myalgia, and Shivering, Significant; prevents daily activity.
Geometric Mean Titers of Influenza Antibodies Before and After Vaccination With a Quadrivalent Influenza Vaccine Administered Via the Intramuscular Route	Day 0 (pre-vaccination) and Day 21 post-vaccination	Immunogenicity was evaluated using the hemagglutination inhibition (HAI) technique.
