What is being measured

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

  1. Proportion of subjects with local reactions and reactogenicity events.

    Measured: Within 7 days after each vaccination

  2. Proportion of subjects reporting adverse events.

    Measured: Within 28 days after each vaccination

Secondary outcomes (4)
  1. Proportion of subjects with anti-MT-5625 IgG seroresponses

    Measured: Day 28 after each vaccination

  2. Proportion of subjects with neutralizing antibody responses

    Measured: Day 28 after each vaccination

  3. Anti-MT-5625 IgG geometric mean titers (GMTs) 28 days after each injection in adults, toddlers, and infants.

    Measured: Day 28 after each vaccination

  4. Neutralizing antibody GMTs against rotavirus 28 days after each injection in adults, toddlers and infants.

    Measured: Day 28 after each vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing MT-5625 low dose, MT-5625 middle dose and MT-5625 high dose in people with Healthy, run by Tanabe Pharma Corporation at 2 sites in 2 countries.

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 5 inclusion and 30 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 6 Aug 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Australia, South Africa. 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 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.

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?

Proportion of subjects with local reactions and reactogenicity events. (time frame: Within 7 days after each 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 NCT03507738, 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 6 Aug 2019.
