FAQ: QUASAR Long Term Extension Interim Analysis

Thank you to Johnson & Johnson for their support on this FAQ Video Module. In this educational video, Jamie Brogan, APRN, from Northwestern Medicine, reviews the latest QUASAR long-term extension data evaluating the efficacy and safety of guselkumab in adults with moderate to severe ulcerative colitis. This discussion highlights approximately two years of follow-up data, offering healthcare providers valuable insight into the long-term durability of treatment response, clinical remission, endoscopic improvement, and overall safety outcomes associated with guselkumab maintenance therapy. Jamie walks through the key findings from the ongoing multicenter extension study, including sustained clinical remission rates, corticosteroid-free remission, endoscopic healing, and histologic-endoscopic mucosal improvement through week 92. The video also reviews the maintenance dosing strategies of guselkumab, including 100 mg every 8 weeks and 200 mg every 4 weeks, and discusses how patients who responded during earlier phases of treatment maintained those responses over time. In addition, the presentation covers important long-term safety findings, including rates of serious infections and adverse events observed throughout the study. This video is designed for gastroenterology APPs, nurse practitioners, physician assistants, gastroenterologists, and healthcare professionals looking to stay current on emerging ulcerative colitis therapies, long-term biologic data, and evolving treatment goals in inflammatory bowel disease (IBD).
