What the trial is, and whether it could suit you
Sequential therapy for Hp was first introduced by Zullo et al. in 2000 and consists of two phases: the first phase involves proton pump inhibitors with one antibiotic, and the second phase involves proton pump inhibitors with two antibiotics. Based on this, the investigators propose a modified sequential therapy, where the first phase uses vonoprazan combined with amoxicillin, and the second phase increases the amoxicillin dosage, forming a high-dose amoxicillin regimen. This new treatment strategy combines the staged nature of sequential therapy with the advantages of high-dose dual therapy, gradually increasing the drug dosage to help patients adapt and reduce side effects (such as nausea, vomiting, and diarrhea), thereby improving patient tolerance.
The primary aim of this study is to compare the vonoprazan combined with high-dose amoxicillin sequential therapy with standard dual the
