About this study

Official title: A Phase 3b Multicenter, Single-Blind Trial to Evaluate the Efficacy of Dexlansoprazole MR 30 mg in Maintaining Control of Gastroesophageal Reflux Disease Symptoms in Subjects on Prior Twice Daily Proton Pump Inhibitor Therapy

The purpose of this study is to determine if patients with well-controlled heartburn symptoms on twice-daily proton pump inhibitor therapy remain well-controlled after stepping down to once-daily (QD) dexlansoprazole modified release (MR) 30 mg.

Read the detailed description

Gastroesophageal reflux disease is recognized as a common and persistent medical problem in the US adult population. Gastroesophageal reflux disease comprises a spectrum of acid-related disorders including symptomatic nonerosive gastroesophageal reflux disease and erosive esophagitis. It affects men and women in nearly equal proportions, and the severity and intensity of heartburn symptoms may be similar in both types of patients.

Dexlansoprazole modified release is a dual delayed release formulation that consists of two types of granules contained in a single capsule. This dual delayed release formulation is designed to extend the duration of drug exposure and maintain pharmacologically active levels over a longer time period.

The purpose of this study is to demonstrate that participants with gastroesophageal reflux disease whose symptoms are well-controlled on twice daily proton pump inhibitors, remain well-controlled when switched to dexlansoprazole MR.

What is being measured

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

  1. Proportion of Participants Who Remain Well Controlled After Switching From Their Current Twice-daily Proton Pump Inhibitor Therapy to Dexlansoprazole MR.

    Well-controlled participants were defined to be participants who completed the study having at least 23 days of evaluable diary entries between Days 15 and 42, inclusive, and had ≤4 occurrences of heartburn during this period.

    Measured: Week 3 through Week 6

Secondary outcomes (13)
  1. Change From Baseline in the Patient Assessment of Upper Gastrointestinal Disorders - Quality of Life (PAGI-QOL) - Daily Activities Subscale in Participants Who Remain Well-controlled.

    PAGI-QOL is a 30-item self-reported instrument assessing health-related quality of life impact of upper gastrointestinal disorders. It includes 30 items across five subscales (daily activities, clothing, diet/food habits, relationship, psychological well-being and distress), scored on a 6-point Likert scale with subscale and total score ranging from 0 (none) to 5 (all the time). For reporting purposes, the scores are reversed and higher scores reflect improved quality of life and positive changes from baseline indicate improved quality of life.

    Measured: Baseline and Week 6.

  7. Change From Baseline in Patient Assessment of Upper Gastrointestinal Disorders - Symptom Severity Index (PAGI-SYM) - Nausea/Vomiting Subscale in Participants Who Remain Well-controlled.

    PAGI-SYM is a 20-item self-reported questionnaire that measures symptom severity of upper gastrointestinal disorders across six subscales (nausea/vomiting, fullness/early satiety, bloating, upper abdominal pain, lower abdominal pain, heartburn/regurgitation) which are summarized by individual subscale scores and a total score. The items are rated on a 6-point Likert scale with subscale and total score ranging from 0 (none) to 5 (very severe). Higher scores indicate higher symptom severity and thus negative changes from baseline indicate decrease in symptom severity.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Dexlansoprazole MR QD in people with Gastroesophageal Reflux, run by Takeda at 52 sites in United States.

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 25 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 3 Feb 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 52 sites in United States. 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?

Yes. Results are posted in the registry (first posted 29 Apr 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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 Participants Who Remain Well Controlled After Switching From Their Current Twice-daily Proton Pump Inhibitor Therapy to Dexlansoprazole MR. (time frame: Week 3 through Week 6). 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 NCT00847808, 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 3 Feb 2012.
