A236 THE EFFECTIVENESS AND SAFETY OF DUAL ADVANCED THERAPIES IN PATIENTS WITH INFLAMMATORY BOWEL DISEASE: A CASE-SERIES

Abstract

Abstract Background Patients with inflammatory bowel disease (IBD) refractory to medical therapy and patients with IBD and concurrent extra-intestinal manifestations (EIMs) pose a challenge within gastroenterology. The small number of approved agents for IBD limits therapeutic options for this population. Utilizing a combination of newer biologic therapies with favourable safety profiles may provide a safe and efficacious option for treating patients with refractory disease or patients with well-controlled IBD but uncontrolled EIMs. Aims The aim of our study was to assess the safety and efficacy of dual advanced therapies for patients with IBD. Methods Patients at London Health Sciences Centre and St. Joseph’s Healthcare Centre on dual advanced therapies for inflammatory bowel disease were retrospectively assessed for a minimum period of 12 months. Major bacterial infection, adverse events, endoscopic, histologic, and clinical remission of IBD, and remission of EIMs of IBD were assessed. Results Five patients with Crohn’s disease receiving dual advanced therapies were identified. Stricturing Crohn’s disease was the predominant phenotype in 80% of the patients. One patient had perianal fistulizing disease. Dual therapy was initiated for concurrent management of EIMs in 80% of patients (enteropathic arthritis in 2 patients, spondyloarthritis in 2 patients, rheumatoid arthritis in 1 patient) and for refractory IBD in one patient. The majority of patients were on a combination of a tumour-necrosis-factor inhibitor and vedolizumab. Other advanced therapies included JAK inhibitors and ustekinumab. The patients were predominantly female (80%) and age at diagnosis was ampersand:003C50 years old in 80% of patients. No adverse events or major bacterial infections were observed during dual therapy. At the end of follow-up, all 5 patients were in clinical remission of their IBD and 4 patients demonstrated endoscopic remission. Only 60% of patients had remission of their EIMs within the follow-up period. Conclusions Our findings suggest that dual advanced therapies are safe and may represent a long-term treatment option for complicated patients with IBD. Funding Agencies None
