PRIMARY outcome

Timeframe: Up to 12 months

Population: Safety Analysis Set, The safety analysis set was defined as all participants who completed the survey.

An adverse event (AE) is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. Adverse drug reaction refers to AE related to administered drug.

Usually, for adults, 10 mg of vonoprazan administered orally once daily. If that dosing proved insufficient, the dosage may have been increased up to 20 mg once daily. Participants received vonoprazan as part of a routine medical care.
Percentage of Participants Who Had One or More Adverse Drug Reactions
2.30 Percentage of Participants

SECONDARY outcome

Timeframe: From the initiation of the maintenance therapy to Month 12 (or discontinuation of the therapy), up to 12 months

Population: Efficacy assessment population, The efficacy assessment population was defined as participants who completed the survey and had efficacy data at baseline and post-baseline time points available.

Endoscopic relapse rate was defined as a percentage of participants who met the criteria of Grade A to D in the modified Los Angeles (LA) classification. The modified LA classification graded endoscopic findings as follows- Grade N: normal mucosa; Grade M: minimal changes to the mucosa, such as erythema and/or whitish turbidity; Grade A: non-confluent mucosal breaks \<5 mm in length; Grade B: nonconfluent mucosal breaks ≥ 5 mm in length; Grade C: confluent mucosal breaks \<75% circumferential; Grade D: confluent mucosal breaks \>=75% circumferential.
