About this study

Official title: Takepron Specified Drug-use Survey "Gastroesophageal Reflux Disease With Dyspepsia Symptoms"

To evaluate the efficacy of 4-week lansoprazole (Takepron) therapy for subjective symptomatic improvement in gastroesophageal reflux disease patients with dyspepsia symptoms

Read the detailed description

This is a special drug use surveillance of lansoprazole (Takepron) with a 4-week observational period, designed to evaluate the efficacy in gastroesophageal reflux disease patients with dyspepsia symptoms (planned sample size, 15000).

The dosage regimen is as follows:

  • For reflux esophagitis, the usual adult dosage is 30 mg of lansoprazole administered orally once daily for up to 8 weeks. For maintenance treatment of repeatedly recurring/relapsing reflux esophagitis, the dosage is 15 mg of lansoprazole administered orally once daily. If insufficient efficacy is observed, the dosage may be increased to 30 mg administered orally once daily.
  • For non-erosive gastroesophageal reflux disease, the usual adult dosage is 15 mg of lansoprazole administered orally once daily for up to 4 weeks.
Being tested

What is being measured

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

  1. Subjective Symptom Improvement Rate

    Subjective symptoms were evaluated as "Disappeared," "Improved," "No change," "Worsened," or "Unclear." These categories were based on investigator's definitions. At Week 4, the rate of improvement (i.e. the frequency of an evaluation of "Disappeared" + "Improved") was calculated for each symptom. The percentage of participants with Improvement by symptom was reported.

    Measured: Start of treatment and Week 4

Secondary outcomes (1)
  1. Frequency of Adverse Events (Adverse Drug Reactions)

    Adverse events observed during the observation period were collected by symptom. For adverse drug reactions, frequencies were tabulated by type and seriousness. Adverse events were defined as any unfavorable and unintended signs, symptoms or diseases temporally associated with administration of lansoprazole whether or not it was considered related to treatment. Among these, events that were considered as having a causal relationship with lansoprazole were defined as adverse drug reactions. The rate of participants with adverse events (adverse drug reactions) was reported.

    Measured: 4 Weeks

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?

Subjective Symptom Improvement Rate (time frame: Start of treatment and Week 4). It is what the study was designed to measure, not a finding.
