Participant Flow

Participants took part in the study at 58 investigative sites in Japan, from 01 September 2015 to 30 April 2017.

Participants with a historical diagnosis of gastric/duodenal ulcer, idiopathic thrombocytopenic purpura, stomach following endoscopic treatment of early gastric cancer, or H. pylori gastritis were enrolled to receive interventions as part of routine medical care. However, participants with gastric MALT lymphoma were not enrolled in the survey.

Measure
Vonoprazan 20 mg
For adults, the following three-drug regimen was administered orally at the same time twice daily for 7 days: 20 mg dose of vonoprazan, 750 mg (potency) dose of amoxicillin hydrate, and 200 mg (potency) dose of clarithromycin. The dose of clarithromycin allowed to be increased as clinically warranted. However, dosage was not to exceed 400 mg (potency)/ dose twice daily. If H. pylori eradication with a three-drug regimen comprising vonoprazan or proton pump inhibitor + amoxicillin hydrate + clarithromycin had been unsuccessful, as an alternative treatment, the following three-drug regimen was administered orally twice daily for 7 days to adults: 20 mg dose of vonoprazan, 750 mg (potency) dose of amoxicillin hydrate, and 250 mg dose of metronidazole. Participants received interventions as part of routine medical care.

SECONDARY outcome

Timeframe: 7 days + 2 months

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

In participants who were determined as achieving H. pylori eradication, the percentage of participants negative for H. pylori (eradication rates) was tabulated by first-line eradication and second-line eradication. Timeframe was defined as duration of triple therapy (7 days) and up to the time of determination of H. pylori eradication after triple therapy (approximately 2 months as maximum duration).
