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.
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 eradication of intestinal metaplasia (CEIM) 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 hydrox…
Inclusion Criteria: * Participants with history of prior esophagogastroduodenoscopy (EGD) with an established diagnosis of BE ≥ 2 cm with either low-grade dysplasia (LGD) or high-grade dysplasia (HGD) or T1a esophageal adenocarcinoma (EAC), naïve to treatment, and being considered for ablation. * Note: An eligible diagnosis from an EGD outside of the enrollment sites is allowed for inclusion as long as the biopsies have been reviewed by two pathologists. The two pathologists could include a pathologist from the referring site and an institutional pathologist at the local enrolling site, tw…
