Personalized vs Standard of Care Treatment for Helicobacter Pylori Eradication Among Veterans (NCT07104318)
Randomized Clinical Trial of Personalized vs Standard of Care Treatment for Helicobacter Pylori Eradication Among Veterans: "VA Eradicate HP"
🩺 Plain-English Summary (8th-Grade Level)
The primary objective of this study is to compare the Helicobacter pylori (H. pylori) eradication rate following empiric bismuth-based quadruple therapy (BQT) versus a personalized H. pylori treatment strategy in treatment-naïve Veterans with confirmed H. pylori infection. This study is an eight-week, parallel two-arm, double-blinded, prospective, single-site randomized clinical trial designed to test the hypothesis that personalized H. pylori therapy achieves higher eradication rates compared to the standard empiric BQT regimen. Secondary outcomes include comparisons of treatment adherence, tolerability, and the incidence of treatment-related side effects and adverse events between the two groups. A total of 360 treatment-naïve Veterans with active H. pylori infection, confirmed by a positive H. pylori stool antigen test (HPsAg), will be enrolled, randomized, and analyzed at the VA San Diego Healthcare System (VASDHS). Participants who meet eligibility criteria and provide informed consent will be randomized in a 1:1 ratio to receive either a 14-day personalized H. pylori treatment regimen (n=180) or a standard 14-day empiric BQT regimen (n=180). Participants randomized to personalized therapy will receive H. pylori treatment that incorporates 1) standard or optimized proton pump inhibitor (PPI) dosing according to participants' CYP2C19 metabolizer phenotype, and 2) tailored antibiotics according to participants' noninvasive (stool) H. pylori antibiotic susceptibility testing (AST). All participants will complete a baseline questionnaire and provide pre-treatment stool and blood samples for H. pylori AST and serum CYP2C19 testing, respectively. Follow-up will include brief telephone interviews during week 1 and week 2 of treatment and again two weeks post-treatment to assess adherence and monitor for adverse events. Cure will be assessed using a post-treatment stool antigen test (HPsAg) at week 8 (four weeks after completing therapy).
