Clinical Trial Summary

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


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.

Outcome

Type Measure Description Time frame Safety issue
Primary 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. Start of treatment and Week 4 No
Secondary 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. 4 Weeks Yes
