Participant Flow

Subjects were enrolled at 105 sites in the United States; date of first dose (04 January 2006; date of last procedure: 14 November 2006).

Subjects had to have endoscopically proven healed erosive esophagitis (EE) after 4 to 8 weeks of treatment with Lansoprazole 30 mg once-daily (QD), Dexlansoprazole Modified Release (MR) 60 mg QD, or Dexlansoprazole MR 90 mg QD in the EE healing studies, T-EE04-084 (NCT00251693) and T-EE04-085 (NCT00251719).

PRIMARY outcome

Timeframe: 6 months

Population: The crude rate analysis was performed on intent-to-treat (ITT) subjects (subjects from Studies T-EE04-084 or T-EE04-085 with endoscopically proven healed EE who received at least 1 dose of study drug in this study and did not have a gap of \>7 days between the EE healing studies and this study) with at least one endoscopy in this maintenance study.

Crude rates analyzed maintenance of healed EE from baseline of this study and considered prematurely discontinued subjects as relapsed.

PRIMARY outcome

Timeframe: 6 months

Population: Life table method for the maintenance rate of healed EE was performed on ITT subjects and included subjects without post-baseline endoscopy as censored.

Percentage of subjects who maintained complete healing of erosive esophagitis as assessed by endoscopy. In the life table method, subjects without post-baseline endoscopy were included as censored; subjects who did not have a recurrence of EE and did not complete the study were also considered censored.

Timeframe: 6 months

Population: The analysis of 24-hour heartburn-free days was performed on ITT subjects with at least one daytime or nighttime heartburn Yes/No question answered during treatment.

The percentage was calculated as the days that were heartburn-free out of the total number of days for which either a daytime or nighttime result was reported.
