About this study

Official title: Comparative Immune Response of Intradermal and Intramuscular Preparations of

This is a prospective, Open label randomized study. A total of 220 adults aged ≥ 60 years will be enrolled and randomized to one of 2 study arms:

  1. Seasonal inactivated intradermal influenza vaccine (15 μg HA (hemagglutinin) per strain/ 0.1 ml dose) (group A - 110 participants)
  2. Seasonal inactivated intramuscular influenza vaccine (15 μg HA per strain/ 0.5 ml dose) (group B - 110 participants) Groups A and B will receive the vaccine at day 1. Total follow up period is 60 days.
Read the detailed description

The consent form will be reviewed and signed by the participant prior to any study-related procedures.

Potential study participants will be assessed based on inclusion and exclusion criteria. Screening procedures, which include taking medical history, vital signs, random blood for dextrostix and vaccination will be performed on day 1.

A total of 220 participants will be randomized into 2 study arms, of which each group of 110 vaccinees will receive either seasonal intradermal influenza vaccine [group A] or seasonal intramuscular influenza vaccine [group B]. The randomization route of vaccination will be kept in concealed envelope at the study site. It will be open after subject signed informed consent form and all inclusion exclusion criteria met for enrollment. Groups A and B will receive the vaccine at day 1. Clinical activities for groups A and B during each visit (total of 5 visits). Blood will be drawn and assayed (for baseline assessment) using HAI (hemagglutination inhibition assay) to the three influenza strains.

What is being measured

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

  1. Immunological end point

    Vaccine is able to induce a 4-fold rise of Hemagglutination inhibition antibodies 70% of vaccinees within 60 days after vaccination (according to EMA (European Medicines Agency) and CBER (Center for Biologics Evaluation and Research) guidelines)

    Measured: with in 60 days post vaccination

Secondary outcomes (1)
  1. To assess safety

    To assess safety of the following trivalent inactivated seasonal influenza vaccine in the older age group

    Measured: 60 Days

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing trivalent inactivated influenza in people with Influenza, Human, run by Mahidol University at 1 site in Thailand.

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 8 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 23 Mar 2016. 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 Thailand. 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?

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?

Immunological end point (time frame: with in 60 days post vaccination). 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 NCT02101749, 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 23 Mar 2016.
