ClinConnect Summary

This clinical trial is testing a new treatment called DWP14012-based triple therapy to see how well it works and how safe it is for people who have a Helicobacter pylori (H. pylori) infection. H. pylori is a type of bacteria that can cause stomach issues, like ulcers. The study will compare this new treatment to another treatment known as DWC202301 to find out if DWP14012 is just as effective. The trial is open for adults aged 19 to 75 who have tested positive for H. pylori and need treatment due to conditions like peptic ulcers or chronic gastritis.

Participants in this trial can expect to receive the new treatment and be closely monitored for their health and any side effects. To join, people must meet certain criteria, including being in the right age range and having specific test results confirming the H. pylori infection. However, there are also some reasons that might prevent someone from participating, such as having recent serious health issues or certain medical conditions. If you or a loved one is interested in participating, it's important to talk to a healthcare provider for more personalized information and to determine eligibility.
