Brief summary

This phase Ⅰb/Ⅱa, single-center, randomized, open-label study was designed to evaluate the safety, tolerability, pharmacokinetics, and preliminary Helicobacter Pylori eradication efficacy in asymptomatic subjects with Helicobacter Pylori infection after multiple doses of TNP-2198 capsules combined with rabeprazole sodium enteric-coated tablets, or TNP-2198 capsules combined with rabeprazole sodium enteric-coated tablets and amoxicillin capsules.

Interventions

On Days 1 to 14, all subjects in each group received TNP-2198 capsule within 30 minutes after breakfast and dinner (BID) for 14 consecutive days. On Day 15, the subjects were only administered once within 30 minutes after breakfast.

DRUGRabeprazole Sodium

On Days 1 to 14, all subjects in each group received rabeprazole within 30 minutes before breakfast and dinner (BID) for 14 consecutive days. On Day 15, the subjects were only administered once within 30 minutes before breakfast.

DRUGAmoxicillin

On Days 1 to 14, all subjects in each group received Amoxicillin capsule within 30 minutes after breakfast and dinner (BID) for 14 consecutive days. On Day 15, the subjects were only administered once within 30 minutes after breakfast.
