Repurposing Itraconazole for Secondary Prevention of Metaplasia and Primary Prevention of Cancer in Patients With High-Risk Barrett's Esophagus in Combination With Ablation
National Cancer Institute (NCI)
Summary
This phase II trial tests how well itraconazole works in combination with the usual standard of care endoscopy with ablation for the prevention of esophageal cancer in patients who have high-risk Barrett's esophagus (BE). BE is a condition in which the lining of the esophagus changes and becomes more like the tissue that lines the intestine. People with Barrett's esophagus have a higher risk of developing esophageal cancer. Itraconazole is a drug used to prevent or treat fungal infections. Ablation refers to the removal of abnormal tissue using heat. Endoscopy is a procedure for looking at the esophagus using a long, flexible tube called an endoscope, which has a video camera at the end. Radiofrequency ablation is a type of heat therapy that uses radiofrequency energy (similar to microwave heat) to destroy the abnormal tissue in the esophagus. Giving itraconazole in combination with standard of care endoscopy with ablation may improve the effects of ablation and prevent esophageal cancer in patients with high-risk Barrett's esophagus.
Description
PRIMARY OBJECTIVE: I. To evaluate if itraconazole in the peri-ablation period in participants with high-risk Barrett's esophagus (BE) can accelerate BE regression i.e., achieve complete resolution of intestinal metaplasia (CRIM) faster than the control group. SECONDARY OBJECTIVES: I. To measure the time to event of complete eradication of dysplasia (CED). II. To measure the rate of BE recurrence during routine follow-up. III. To determine the safety and tolerability of itraconazole in participants with high-risk BE. IV. To correlate levels of itraconazole and its primary metabolite hydroxy…
