About this study

Official title: Immunogenicity (Humoral and Cellular Immune Responses) and Safety of the Seasonal Flu Vaccine in Elderly and in SOT Recipients

This study will assess the effect of a different dose of the seasonal flu vaccine 2013-2015 on the immune response to improve the investigators understanding of cellular and humoral immune responses induced. The scope of this study is to determine the profile of cellular activation and antibody production in the ageing immune system following flu immunization.

This study will enroll 100 male or female subjects ≥65 year old and 90 transplant recipients. These persons will be deemed to be " at risk " in case of influenza infection and should be vaccinated according to Swiss Federal Office of Public Health. A medical doctor from the CHUV will inform the patients about the present study and ask them whether they would be willing to participate in the study.

All subjects will be distributed between the two groups according to a computer-generated randomization sequence. The randomization will be done in blocks to ensure balance across groups. The participants and site staff will not be blinded due to the different administration assignments.

Group 1 subjects will receive a single dose and group 2 subjects a double dose of MUTAGRIP® manufactured by Sanofi Pasteur containing A/California/7/2009 (H1N1); A/Texas/50/2012 (H3N2); B/Massachusetts/2/2012. Vaccine immunogenicity and safety will be assessed 1, 2, 4 and 24 weeks after vaccination.

Study duration per volunteer is 6 months after vaccination.

Being tested
Single dose MUTAGRIP® influenza vaccine, Double dose of MUTAGRIP® influenza vaccine

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Single dose MUTAGRIP® influenza vaccineDrug

    All subjects will receive either a single or double doses of MUTAGRIP® containing A/California/7/2009 (H1N1); A/Texas/50/2012 (H3N2); B/Massachusetts/2/2012. The double dose regimen will be administered at the same time.

  • Double dose of MUTAGRIP® influenza vaccineDrug

    All subjects will receive either a single or double doses of MUTAGRIP® containing A/California/7/2009 (H1N1); A/Texas/50/2012 (H3N2); B/Massachusetts/2/2012. The double dose regimen will be administered at the same time.

What is being measured

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

  1. Change from Baseline in Immunogenicity

    Humoral immune responses (antibodies directed against all three strains A/California/7/2009 (H1N1); A/Texas/50/2012 (H3N2); B/Massachusetts/2/2012).

    Measured: weeks 2, 4 and 24 after vaccination

  2. Change from Baseline in Immunogenicity

    Cellular immune responses directed against all three strains A/California/7/2009 (H1N1); A/Texas/50/2012 (H3N2); B/Massachusetts/2/2012.

    Measured: weeks 1, 2, 4 and 24 after vaccination

Secondary outcomes (1)
  1. Number of Adverse Events as a Measure of Safety and Tolerability

    To evaluate safety and tolerability of the influenza vaccine (split virion, inactivated), MUTAGRIP®, administered in single or double dose.

    Measured: 24 weeks after vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Single dose MUTAGRIP® influenza vaccine and Double dose of MUTAGRIP® influenza vaccine in people with Healthy Volunteers, run by University of Lausanne Hospitals at 1 site in Switzerland.

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 7 inclusion and 7 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 26 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Change from Baseline in Immunogenicity (time frame: weeks 2, 4 and 24 after 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?

On the ClinicalTrials.gov record for NCT02746783, 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 26 Mar 2020.
