About this study

Official title: Immunogenicity and Safety of Multiple Formulations of an Intramuscular Inactivated, Split Virion Swine-origin A/H1N1 Influenza Vaccine With and Without Adjuvant in Healthy European Adult and Elderly Subjects

The purpose of this study is to generate data on immunogenicity and safety of the monovalent H1N1 vaccine in support of the development and registration.

Primary objectives:

  • To describe the immune response to study vaccine 21 days after each vaccination.
  • To describe the antibody persistence 8 months after the first vaccine administration using hemagglutination inhibition (HAI) method in a randomized subset of adult subjects who received two injections.
  • To describe the immune response against the A/H1N1 strain using HAI method 21 days after a vaccination with the 2010-2011 Northern Hemisphere (NH) seasonal trivalent influenza vaccine (TIV) administered 13 months after the first vaccination in a subset subjects who received the A/H1N1 influenza vaccine and in subjects naïve to the swine origin A/H1N1 strain.
  • To describe the safety profiles of study vaccines in all participants.
Read the detailed description

All participants will receive two injections of their randomized vaccine on Day 0 and Day 21, respectively.

A subset of the participants will receive a third vaccine injection (2010-2011 Northern Hemisphere [NH] seasonal trivalent influenza vaccine [TIV]) approximately 13 months after the first vaccination; additionally, a subset of participants' naïve to the swine-origin A/H1N1 strain will also receive one vaccine injection of the 2010-2011 NH seasonal TIV.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Swine A/H1N1 influenza vaccine (split virion, inactivated) in people with Influenza and Swine-origin A/H1N1 Influenza, run by Sanofi Pasteur, a Sanofi Company at 6 sites in France.

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 10 inclusion and 27 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 14 Jan 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in France. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

To provide information concerning the immunogenicity of Swine A/H1N1 influenza vaccine (time frame: 21 days post-vaccination). The study lists 2 primary outcomes in all. 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 14 Jan 2014.
