ClinConnect Summary
This clinical trial is exploring how two different treatment methods can help eliminate a common stomach infection called Helicobacter pylori (H. pylori). The researchers want to see how these treatments affect the balance of bacteria in the intestines, which is important for overall gut health. They will look at changes in the variety and composition of gut bacteria before and after treatment, helping to understand any potential side effects or drug resistance issues that may arise from these therapies.
To participate in this study, you need to be between 18 and 70 years old and have a confirmed H. pylori infection without having previously received treatment for it. Women who can become pregnant must agree to use reliable birth control during the study. If you join, you can expect to receive one of the two treatment methods and will be asked to provide samples to track how your gut bacteria change over time. It's important to note that there are specific health conditions and treatments that could exclude you from participating, so discussing your medical history with the study team will be essential.
