The Eradication Rate of Helicobacter Pylori Infection

Eradication rate of H. pylori is defined as negative urea breath test result.

Time frame: Group A, B,C,control group: Urea breath test is assessed Day 44~Day 50 after the first dose; Group D: Urea breath test is assessed Day 37~ Day 43 after the first dose

Population: Modified Intent-to-Treat Analysis Set (mITT): Refers to all randomized participants who have 14C UBT performed on Day 28 to 34 after the last dose of the study.
