About this study

Official title: Therapeutic Response to Lansoprazole Among Different Subgroups of Functional Dyspepsia: a Multicenter, Randomized, Double-blind, Placebo-controlled Trial

Pharmacotherapy for functional dyspepsia remains unsatisfactory. Previous randomized trials reported conflicting results on clinical effectiveness of proton pump inhibitor in patients with functional dyspepsia. This study aims to examine whether lansoprazole 15mg is more effective than placebo for functional dyspepsia in Taiwanese patients, and to investigate the association between subgroups of patients and therapeutic response.

Read the detailed description

This is a prospective double-blind randomized placebo-controlled trial. A total of 450 dyspeptic adult patients, who are diagnosed with functional dyspepsia in accordance with Rome III criteria, are randomly allocated in a 1:1 proportion to receive either lansoprazole 15mg or placebo once daily for 8 weeks. Primary outcome is complete relief of dyspeptic symptoms. Secondary outcomes include significant symptomatic relief, improvement of dyspepsia severity, and health-related quality of life. We use a multiple logistic regression analysis to investigate whether dyspepsia subgroups are associated with different therapeutic responses.

    Measured: within one week after complete study medication

Secondary outcomes (3)
  1. satisfactory therapeutic response (complete or marked relief of symptoms)

    Measured: within one week after complete study medication

  2. change of dyspepsia severity as measured by total scores of Hong Kong index

    Measured: within one week after completing study medication

  3. health-related quality of life as reflected in every aspect of SF-36

    Measured: within one week after completing study medication

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Lansoprazole in people with Functional Dyspepsia, run by National Taiwan University Hospital at 4 sites in Taiwan.

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 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: stopped early, as of the sponsor's last update on 15 Apr 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Taiwan. 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. 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 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 was stopped early (reason given: failure to recruit enough patients). Results are not available in the source record.

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?

complete relief of dyspeptic symptoms (time frame: within one week after complete study medication). 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 NCT01040455, 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 15 Apr 2014.
