About this study
Official title: A Phase III, Multicenter, Randomized, Double-Blind, Controlled Study to Evaluate the Safety and Immunogenicity of Two Trivalent Subunit Influenza Vaccines in Healthy Adult Subjects
The purpose of this study is to evaluate the immunologic equivalence of three consecutive lots of a cell based trivalent subunit influenza vaccine (TIVc), and to assess immunogenicity, safety and tolerability of the vaccine and an egg based trivalent subunit influenza vaccine (TIVf).
The study comprised 1 vaccination, 2 clinic visits, 3 reminder calls and 2 blood draws. Female subjects of childbearing potential were tested for pregnancy before the administration of the vaccine and included only if using and agreeing to continue to use contraception during the course of the study.
The total study participation time per subject is about 3 weeks.

What is being measured
The primary outcome is the main question the study is designed to answer.
Immunologic Equivalence of 3 Consecutive Influenza Vaccine (TIVc) Production Lots.
Hemagglutination inhibition (HI) geometric mean titers (GMTs) achieved by subjects, for each three vaccine strains, three weeks after one vaccination of one lot of TIVc vaccine (Day 22), evaluated using HI antigen assay.
Measured: Day 22
Secondary outcomes (3)
Percentages of Subjects Who Achieved HI Seroconversion and HI Titer ≥1:40 Against Each of Three Strains After One Vaccination of TIVc and TIVf Vaccine.
Percentages of subjects achieving HI seroconversion after each of three vaccine strains were measured three weeks after vaccination of TIVc or TIVf vaccine (day 22).
Percentages of subjects who achieved HI titer ≥1:40 against each of three vaccine strains were measured three weeks after one vaccination of TIVc or TIVf vaccine.
HI assay analysis for TIVc vaccine was based on cell-based antigen and for TIVf vaccine was based on egg based antigen.
According to Center for Biologics Evaluation and Research recommendations (CBER 2007), CBER criteria are met when the lower limit of the 2-sided 95% CI for seroconversion/significant increase is ≥ 40%, and the lower limit of the 2-sided 95% CI for HI titers ≥ 1:40 is ≥ 70%.
Measured: Day 22
Number of Subjects Who Reported Solicited Local and Systemic Adverse Events After One Vaccination of TIVc and TIVf
Safety was assessed as the number of subjects who reported solicited local and systemic adverse events from day 1 up to and including day 7 after vaccination of TIVc and control vaccines.
Measured: Day 1 through day 7 (without 30 min)
Number of Subjects With Unsolicited Adverse Events
Safety was assessed as the number of subjects who reported Unsolicited Adverse Events after vaccination of TIVc and control vaccine.
Measured: Day 1 through day 22

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing TIVc_LOT A, TIVc_LOT B and TIVc_LOT C in people with Prophylaxis: Influenza, run by Novartis Vaccines at 24 sites in United States.
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 3 inclusion and 2 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 11 Jun 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 24 sites in United States. 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 7 Aug 2015). 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?
Immunologic Equivalence of 3 Consecutive Influenza Vaccine (TIVc) Production Lots. (time frame: Day 22). 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 11 Jun 2019; AzTrials last refreshed its copy on 8 Nov 2026.
