About this study

Official title: Drug Use Surveillance of Takecab Tablets "Supplement to Helicobacter Pylori Eradication"

The purpose of this study is to evaluate the safety and efficacy on participants receiving first-line eradication and second-line eradication including vonoprazan (Takecab) tablets (triple therapy) in the routine clinical setting.

Read the detailed description

The drug being tested in this study is called Vonoprazan (Takecab). Vonoprazan is being tested to treat people who have gastric ulcer, duodenal ulcer, gastric mucosa-associated lymphoid tissue (MALT) lymphoma, idiopathic thrombocytopenic purpura, stomach following endoscopic treatment of early gastric cancer, or H. pylori gastritis. This study will look at the presence or absence of new concerns regarding the safety of triple therapy with Vonoprazan tablets, amoxicillin, and clarithromycin (first-line eradication) and triple therapy with Vonoprazan tablets, amoxicillin, and metronidazole (second-line eradication) for supplemental Helicobacter pylori (H. pylori) eradication in the routine clinical setting. The study will enroll approximately 500 patients.

First-line eradication

  • Vonoprazan 20 mg / Proton pump inhibitor
  • Amoxicillin hydrate 750 mg
  • Clarithromycin 200 mg

If H. pylori eradication with a three-drug regimen comprising vonoprazan or proton pump inhibitor + amoxicillin hydrate + clarithromycin has been unsuccessful.

Second-line eradication

  • Vonoprazan 20 mg
  • Amoxicillin hydrate 750 mg
  • metronidazole 250 mg

This multi-center trial will be conducted in Japan.

Being tested
Vonoprazan, Amoxicillin hydrate, Clarithromycin, Metronidazole
Medical subject headings
Duodenal Ulcer, Purpura, Thrombocytopenic, Idiopathic

Study groups in NCT03219723
Study groupRoleWhat they receive
Vonoprazan 20 mgFor adults, the following three-drug regimen will be 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 may be increased as clinically warranted. However, dosage should not 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 has been unsuccessful, as an alternative treatment, the following three drugs will be 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 will receive interventions as part of routine medical care.
Receives: Drug: Vonoprazan; Drug: Amoxicillin hydrate; Drug: Clarithromycin; Drug: Metronidazole

What is being measured

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

  1. Percentage of Participants Who Had One or More Adverse Drug Reactions

    Adverse drug reaction refers to adverse events related to administered drug. 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).

    Measured: Up to 7 days and 2 months

Secondary outcomes (1)
  1. H. Pylori Eradication Rate

    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).

    Measured: 7 days + 2 months
