About this study

Official title: A Randomized, Controlled Clinical Study on the Effect of Non-digestible Polysaccharides (NPS) on the Immune Response to Influenza Vaccination in Elderly

The aim of the study is to estimate the effect size of a 5-week consumption period of different dietary non-digestible polysaccharides (NPS) on antibody response to influenza vaccination and cellular immunity of healthy volunteers (aged ≥ 50) for clarifying whether these NPS may enable enhancement of immune defence and to estimate the sample size for a confirmative trial. Furthermore the effects on faecal microbiota and its metabolites will be investigated.

Read the detailed description

The study is conducted in the frame of the collaborative project 'FibeBiotics' (Nr. 289517) (Fibers as support of the Gut and Immune function of Elderly - From polysaccharide compound to health claim) within the Seventh Framework Programme (FP7) for Research and Technological Development of the European Union (EU).

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing NPS in people with Immunosenescence, run by Clinical Research Center Kiel GmbH.

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 29 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 Nov 2016. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?

Geometric mean titre of antibodies against one of the 3 influenza strains in HI test (time frame: 3 weeks after 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 Nov 2016.
