What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Cell culture-derived trivalent subunit influenza vaccine (cTIV)Biological
One vaccination (0.5 mL) of cell culture-derived influenza vaccine (cTIV) was administered in the deltoid muscle
Egg-derived trivalent subunit influenza vaccine (TIV)Biological
One vaccination (0.5 mL) of egg-derived influenza virus vaccine (TIV) was administered in the deltoid muscle
| Study group | Role | What they receive |
|---|---|---|
| Cell culture-derived influenza vaccine (cTIV) | Experimental | Not described Receives: Biological: Cell culture-derived trivalent subunit influenza vaccine (cTIV) |
| Egg-derived influenza virus vaccine (TIV) | Active comparator | Not described Receives: Biological: Egg-derived trivalent subunit influenza vaccine (TIV) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Percentages Of Subjects Who Achieved HI Titer ≥40 After One Vaccination of Cell Culture-derived (cTIV) or Egg-derived (TIV) Influenza Subunit Vaccines
Immunogenicity was measured as the percentage of adults (≥18 to ≤60 years) and elderly (≥61 years) achieving HI titers ≥40 at baseline (day 1) and three weeks (day 22) after one vaccination of cTIV or TIV vaccine for each of three vaccine strains, evaluated using the hemagglutination inhibition (HI) egg-derived antigen assay.
In compliance with the requirements of the EMEA recommendations (CPMP/BWP/2490/00, CPMP/BWP/214/96), this criterion is met if the percentage of subjects achieving HI titers ≥40 is >70% in the ≥18 to ≤60 years of age group or >60% in the ≥61 years of age group.
Measured: Before vaccination (day 1) and three weeks after vaccination (day 22)
Percentages Of Subjects Who Achieved Seroconversion Or Significant Increase In HI Titer After One Vaccination of cTIV or TIV
Seroconversion or significant in HI titer is defined as the percentage of subjects with a prevaccination HI titer <10 (negative) to a postvaccination titer ≥40; or in subjects with prevaccination HI titer ≥10, at least a 4-fold increase in postvaccination HI titer. In compliance with the requirements of the EMEA recommendations (CPMP/BWP/2490/00, CPMP/BWP/214/96), the criterion is met if the percentage of subjects achieving seroconversion/significant increase is >40% in the ≥18 to ≤60 years of age group or >30% in the ≥61 years of age group.
Measured: Three weeks after vaccination (day 22)
Geometric Mean Ratio of Subjects After One Vaccination of cTIV or TIV
Immunogenicity was measured as the geometric mean ratio (GMR), calculated as the ratio of postvaccination to prevaccination HI Geometric Mean Titers (GMTs), three weeks after (day 22) one vaccination of cTIV or TIV. In compliance with the requirements of the EMEA recommendations (CPMP/BWP/2490/00, CPMP/BWP/214/96), this criterion is met if the GMR (day 22/day 1) in HI antibody titer is >2.5 in the ≥18 to ≤60 years of age group or >2.0 in the ≥61 years of age group.
Measured: Three weeks after vaccination (day 22)
Secondary outcomes (1)
Number of Subjects Who Reported Solicited Local and Systemic Reactions up to 7 Days After Vaccination
The solicited local and systemic reactions were collected from day 1 up to and including day 7 after vaccination for both the vaccine groups.
Measured: Up to 7 days postvaccination

Primary outcome
Percentages Of Subjects Who Achieved HI Titer ≥40 After One Vaccination of Cell Culture-derived (cTIV) or Egg-derived (TIV) Influenza Subunit Vaccines
Time frame: Before vaccination (day 1) and three weeks after vaccination (day 22)
Immunogenicity was measured as the percentage of adults (≥18 to ≤60 years) and elderly (≥61 years) achieving HI titers ≥40 at baseline (day 1) and three weeks (day 22) after one vaccination of cTIV or TIV vaccine for each of three vaccine strains, evaluated using the hemagglutination inhibition (HI) egg-derived antigen assay. In compliance with the requirements of the EMEA recommendations (CPMP/BWP/2490/00, CPMP/BWP/214/96), this criterion is met if the percentage of subjects achieving HI titers ≥40 is >70% in the ≥18 to ≤60 years of age group or >60% in the ≥61 years of age group.
Percentages Of Subjects Who Achieved Seroconversion Or Significant Increase In HI Titer After One Vaccination of cTIV or TIV
Time frame: Three weeks after vaccination (day 22)
Seroconversion or significant in HI titer is defined as the percentage of subjects with a prevaccination HI titer <10 (negative) to a postvaccination titer ≥40; or in subjects with prevaccination HI titer ≥10, at least a 4-fold increase in postvaccination HI titer. In compliance with the requirements of the EMEA recommendations (CPMP/BWP/2490/00, CPMP/BWP/214/96), the criterion is met if the percentage of subjects achieving seroconversion/significant increase is >40% in the ≥18 to ≤60 years of age group or >30% in the ≥61 years of age group.
Geometric Mean Ratio of Subjects After One Vaccination of cTIV or TIV
Time frame: Three weeks after vaccination (day 22)
Immunogenicity was measured as the geometric mean ratio (GMR), calculated as the ratio of postvaccination to prevaccination HI Geometric Mean Titers (GMTs), three weeks after (day 22) one vaccination of cTIV or TIV. In compliance with the requirements of the EMEA recommendations (CPMP/BWP/2490/00, CPMP/BWP/214/96), this criterion is met if the GMR (day 22/day 1) in HI antibody titer is >2.5 in the ≥18 to ≤60 years of age group or >2.0 in the ≥61 years of age group.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Cell culture-derived trivalent subunit influenza vaccine (cTIV) and Egg-derived trivalent subunit influenza vaccine (TIV) in people with Influenza, run by Novartis Vaccines at 5 sites in Poland.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 25 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 1 Jan 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in Poland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 21 Feb 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentages Of Subjects Who Achieved HI Titer ≥40 After One Vaccination of Cell Culture-derived (cTIV) or Egg-derived (TIV) Influenza Subunit Vaccines (time frame: Before vaccination (day 1) and three weeks after vaccination (day 22)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00492063, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Jan 2016.
