What is being measured

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

  1. Endoscopic Healing Rate of Duodenal Ulcer Over 6 Weeks

    Endoscopic healing rate : Rate of participants who have endoscopically confirmed all of the white coatings disappeared.

    Measured: 6 weeks

Secondary outcomes (3)
  1. Endoscopic healing Rates of Duodenal Ulcer on Endoscopy over 4 weeks

    Measured: 4 weeks

  2. Endoscopic healing Rates of Gastric Ulcer on Endoscopy at week 2

    Measured: 2 weeks

  3. Change from Baseline in the Incidence of Gastrointestinal Symptoms Associated with Duodenal Ulcer

    Measured: Baseline and 6 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing TAK-438 and Lansoprazole in people with Duodenal Ulcer, run by Takeda at 64 sites in Japan.

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 9 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 20 Aug 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 64 sites in Japan. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Endoscopic Healing Rate of Duodenal Ulcer Over 6 Weeks (time frame: 6 weeks). 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 NCT01452724, 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 20 Aug 2013.
