About this study

Official title: A Phase IV, Multi-Center, Active-Controlled, Observer-Blind Study to Evaluate the Safety of a Trivalent Subunit Influenza Vaccine Produced Either in Mammalian Cell Culture (Optaflu®) or in Embryonated Hen Eggs (Agrippal®) in Adults and Elderly With and Without Underlying Medical Conditions, and to Evaluate the Immunogenicity in a Subset of Subjects With Underlying Medical Conditions

Evaluation of the safety of Trivalent Subunit Influenza Vaccine Produced either in Mammalian Cell Culture or in embryonated Hen Eggs in subjects 18 years of age and above with and without underlying medical conditions and evaluation of the immunogenicity in a subset of subjects with underlying medical conditions, compared to an egg-based vaccine in a post marketing setting.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Subjects Who Reported At Least One Reactogenicity Sign After One Vaccination of TIV or cTIV

    Safety was assessed as the number of all subjects who reported at least one sign of reactogenicity after one vaccination of egg-derived (TIV) or cell culture-derived (cTIV) influenza virus vaccine from Day 1 through Day 7 post-vaccination.

    Measured: From Day 1 up to and including Day 7 post-vaccination

Secondary outcomes (6)
  1. Number of Healthy Adults and Elderly Who Reported Solicited Local and Systemic Adverse Events (AEs) After One Vaccination of TIV or cTIV

    Analysis was performed on a subset of safety population which included the healthy adults (≥18 to ≤60 years) and elderly (≥61 years).

    Measured: From Day 1 through Day 7 post-vaccination

  2. Number of Adults and Elderly With Underlying Medical Conditions Who Reported Solicited Local and Systemic Adverse Events After One Vaccination of TIV or cTIV

    Analysis was performed on a subset of safety population which included the adults (≥18 to ≤60 years) and elderly (≥61 years) with underlying medical conditions.

    Measured: From Day 1 through Day 7 post-vaccination

  3. Percentages Of Subjects With Underlying Medical Conditions Who Achieved Hemagglutination Inhibition (HI) Titer ≥40 After One Vaccination of TIV or cTIV

    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 TIV or cTIV for each of three vaccine strains, evaluated using hemagglutination inhibition (HI) egg-derived antigen assay. This criterion is met according to European (CHMP) guideline if the percentage of subjects achieving HI titers ≥40 is >70% (≥18 to ≤60 years), or >60% (≥61 years).

    Measured: Before vaccination (Day 1) and three weeks after vaccination (Day 22)

  4. Percentages Of Subjects Who Achieved Seroconversion Or Significant Increase In HI Titers After One Vaccination of TIV or cTIV

    Seroconversion or significant increase in HI titer as per CHMP criteria for each of the three strains is defined as the percentage of subjects with a prevaccination HI titer <10 to a postvaccination titer ≥40; or in subjects with prevaccination HI titer ≥10, a ≥4-fold increase in postvaccination HI antibody titer. According to the CHMP criteria, the percentage of subjects achieving seroconversion/significant increase should be >40% (≥18 to ≤60 years) or >30% (≥61 years).

    Measured: Three weeks post-vaccination (Day 22)

  5. Geometric Mean Titers of Subjects With Underlying Medical Conditions After One Vaccination of TIV or cTIV

    Immunogenicity was measured as HI geometric mean titers (GMTs) of subjects with underlying conditions, directed against each of three vaccine strains at baseline (Day 1) and three weeks after vaccination (Day 22) in adults (≥18 to ≤60 years) and elderly (≥61 years).

    Measured: Before vaccination (Day 1) and three weeks after vaccination (Day 22)

  6. Geometric Mean Ratio of Subjects With Underlying Medical Conditions After One Vaccination of TIV or cTIV

    Immunogenicity was measured as the geometric mean ratio (GMR), calculated as the ratio of postvaccination to prevaccination HI GMTs for each of the three strains, three weeks after one vaccination (Day 22) of TIV or cTIV. CHMP criteria is considered fulfilled for each of the three strains if the geometric mean increase GMR (Day 22/Day 1) in HI antibody titer is >2.5 (≥18 to ≤60 years) or >2.0 (≥61 Years).

    Measured: Three weeks post-vaccination (Day 22)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Cell-derived influenza vaccine and Egg-derived influenza vaccine in people with Seasonal Influenza and Vaccine, run by Novartis Vaccines at 15 sites in Germany.

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 2 inclusion and 11 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 17 Feb 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites in Germany. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 18 Apr 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?

Number of Subjects Who Reported At Least One Reactogenicity Sign After One Vaccination of TIV or cTIV (time frame: From Day 1 up to and including Day 7 post-vaccination). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 17 Feb 2016.
