Phase 4
Completed
Conditions
Helicobacter Pylori Infection
Interventions
Registration Number
NCT05342532
Lead Sponsor
Icahn School of Medicine at Mount Sinai
Brief Summary

A phase 4 prospective, randomized, open-label clinical trial evaluating the efficacy of high dose dual therapy vs standard triple therapy in a diverse, urban New York City population.

Detailed Description

All patients, at least 18 years of age, with a chief complaint of dyspepsia and documented treatment-naïve HP infection diagnosed on UBT, esophagogastroduodenoscopy (EGD) with HP biopsy, or SAT were recruited for the study. Dyspepsia was defined as persistent or recurrent abdominal pain for at least one month. All subjects who met inclusion criteria were randomly assigned by a computerized system to one of two treatment groups: standard triple therapy (STT) or high-dose dual therapy (HDDT). After patient randomization, all potential side effects were discussed. Education regarding the importance of adherence to complete the full 14 day regimen was provided. Patients were provided an electronic prescription for the respective assigned regimen along with a medication log to self-report drug compliance. The patients were asked to record medication compliance and report any adverse events to research personnel.

After completion of their assigned regimen, subjects were scheduled for a post-treatment visit, 4 weeks after completion of the study. During this period, patients were asked to abstain from taking PPI's to avoid false negative eradication testing. At the post-treatment visit, a medication log and empty pill bottles were brought in to ascertain compliance (defined as completing at least 90% of all prescribed medications).
