What this trial studies

This clinical trial aims to assess the efficacy and safety of Ilaprazole 10 mg in preventing peptic ulcers associated with NSAID use. The study will compare Ilaprazole to an active control, Lansoprazole, to determine if it is non-inferior in preventing the occurrence of peptic ulcers over a 24-week period. Participants will include adults who require continuous NSAID treatment and have specific risk factors for peptic ulcers. The trial will involve random assignment to receive either Ilaprazole, Lansoprazole, or placebos.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 19 years or older who are on continuous NSAID treatment and have risk factors for peptic ulcers.

Not a fit: Patients with severe gastrointestinal conditions or a history of malignancy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new effective option for preventing NSAID-related peptic ulcers in at-risk patients.

How similar studies have performed: Previous studies have shown success with similar proton pump inhibitors in preventing NSAID-related ulcers, making this approach promising.
