A Study to Assess the Immunogenicity and Safety of CSL's 2012/2013 Formulation of Enzira® Vaccine in Healthy Volunteers

25. april 2018 opdateret af: Seqirus

A Phase IV, Single-Centre, Open-label Study to Evaluate the Immunogenicity and Safety of the 2012/2013 Formulation of the Enzira® Vaccine in Two Groups of Healthy Volunteers: 'Adults' (Aged 18 to 59 Years) and 'Older Adults' (Aged 60 Years or Older)

This is a study to assess the immune (antibody) response and safety of the 2012/2013 formulation of Enzira® (CSL Influenza vaccine) in healthy adult volunteers aged 18 years or older.

  • Females of child-bearing potential (i.e., ovulating, pre-menopausal, not surgically sterile) must be abstinent or be willing to use a medically accepted contraceptive regimen for the duration of the study. Females of child-bearing potential must return a negative urine pregnancy test result prior to vaccination with the vaccine.

Exclusion Criteria:

  • Known hypersensitivity to a previous vaccination with influenza vaccine or allergy to eggs, ovalbumin, chicken protein, neomycin, polymyxin, or any components of the vaccine.
  • Clinical signs of an active infection.
  • A clinically significant medical condition.
  • Vaccination with a seasonal or experimental influenza virus vaccine in the 6 months preceding study entry.
  • Females who are pregnant or lactating.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Adults
Healthy volunteers aged 18 to 59 years received a single 0.5 mL dose of CSL Influenza Vaccine by intramuscular or subcutaneous injection.
Biologisk: CSL Influenza Vaccine
The study vaccine (CSL Influenza Vaccine) is a sterile, thiomersal-free suspension containing 45 mcg total haemagglutinin antigen per 0.5 mL dose (15 mcg each of the three recommended influenza strains for the Northern Hemisphere 2012/2013 influenza season). The vaccine will be administered by intramuscular or subcutaneous injection.
Andre navne:
  • Afluria® vaccine
  • Enzira® vaccine
Eksperimentel: Older Adults
Healthy volunteers aged 60 years or older received a single 0.5 mL dose of CSL Influenza Vaccine by intramuscular or subcutaneous injection.
Biologisk: CSL Influenza Vaccine
The study vaccine (CSL Influenza Vaccine) is a sterile, thiomersal-free suspension containing 45 mcg total haemagglutinin antigen per 0.5 mL dose (15 mcg each of the three recommended influenza strains for the Northern Hemisphere 2012/2013 influenza season). The vaccine will be administered by intramuscular or subcutaneous injection.

Hvad måler undersøgelsen?

Primære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Procentdelen af ​​evaluerbare deltagere, der opnår en HI-titer ≥ 40 eller enkelt radial hæmolyse (SRH)-areal ≥ 25 mm2.
Tidsramme: Cirka 21 dage efter vaccination
Til influenzavirusstammerne H1N1, H3N2 og B. Bemærk: Ingen SRH-data blev indsamlet.
Cirka 21 dage efter vaccination
The Percentage of Evaluable Participants Achieving Seroconversion or Significant Increase in Antibody Titre.
Tidsramme: Approximately 21 days after vaccination
As per the criteria specified in the CPMP/BWP/214/96 Note for Guidance on Harmonisation of Requirements for Influenza Vaccines. For haemagglutination inhibition (HI), seroconversion (H1N1, H3N2, and B influenza virus strains) was defined as achieving a post-vaccination titre of ≥ 40 for those participants with a pre-vaccination HI titre of < 10. A significant increase (H1N1, H3N2, and B influenza virus strains) was defined as a four-fold or greater increase in HI titre for those participants with a pre-vaccination HI titre of ≥ 10.
Approximately 21 days after vaccination
The Geometric Mean Fold Increase (GMFI) in Antibody Titre After Vaccination.
Tidsramme: Approximately 21 days after vaccination
GMFI (H1N1, H3N2, and B influenza virus strains) was defined as the geometric mean of the fold increases of post-vaccination antibody titre over the pre-vaccination antibody titre.
Approximately 21 days after vaccination

Foranstaltningsbeskrivelse
Tidsramme
Frequency and Intensity of Any Solicited Adverse Events (AEs).
Tidsramme: During the 4 days after vaccination (Day 0 plus 3 days)

The percentage of participants reporting any solicited AEs and the percentage of participants reporting any solicited AEs with severe intensity. Note: Intensity of solicited AEs was collected for temperature only.

Solicited local AEs collected included induration >50 mm, erythema, ecchymosis, and pain at the vaccination site.

Solicited systemic AEs collected included temperature above 38.0°C, chills, and malaise.

Solicited AE intensity grading: Mild: symptoms were easily tolerated and there was no interference with daily activities; Moderate: enough discomfort to cause some interference with daily activities; Severe: symptoms that prevented normal, everyday activities.
During the 4 days after vaccination (Day 0 plus 3 days)
Frequency of Any Unsolicited AEs.
Tidsramme: After vaccination until the end of the study; approximately 21 days
The percentage of participants reporting any unsolicited AEs. Unsolicited AEs included AEs other than those specifically solicited.
After vaccination until the end of the study; approximately 21 days
