Brief summary
This phase IV, multicenter, open-label randomized controlled trial will evaluate whether a JAK inhibitor discontinuation strategy is superior to standard maintenance therapy in adult patients with ulcerative colitis who are in sustained deep remission. A total of 224 patients treated with tofacitinib, upadacitinib, or filgotinib will be randomized to either treatment withdrawal or continuation of maintenance therapy and followed for 104 weeks. The primary objective is to compare safety, efficacy, and patient satisfaction at Week 52, while secondary objectives include assessment of remission maintenance, quality of life, treatment exposure, endoscopic outcomes, and relapse rates
Detailed description
Background: Janus kinase (JAK) inhibitors are effective oral therapies for moderate-to-severe ulcerative colitis (UC). Their lack of immunogenicity provides a unique opportunity to evaluate treatment withdrawal and intermittent treatment strategies. However, safety concerns raised by regulatory agencies, including increased risks of infections, venous thromboembolism, major adverse cardiovascular events, and malignancies, support the investigation of strategies aiming to reduce long-term exposure to JAK inhibitors while maintaining disease control. Objective: To demonstrate the superiority of a JAK inhibitor stopping strategy compared with standard maintenance therapy in terms of treatment safety, efficacy, and patient satisfaction in adults with ulcerative colitis in deep remission. Study Design: This is a phase IV, prospective, multicenter, open-label, randomized controlled trial. Adult patients with ulcerative colitis receiving a stable dose of tofacitinib, upadacitinib, or filgotinib for at least 12 months and achieving sustained steroid-free clinical, biological, and endoscopic remission for at least 6 months will be randomized to either treatment discontinuation or continuation of standard maintenance therapy. A total of 224 participants will be enrolled and followed for 104 weeks. Primary Endpoint: The primary endpoint is a composite outcome assessing treatment safety, efficacy, and patient satisfaction during the first 52 weeks after randomization. Patient satisfaction will be evaluated using the Treatment Satisfaction Questionnaire for Medication (TSQM 1.4). Secondary Endpoints: Secondary outcomes include adverse events and serious adverse events, maintenance of remission, treatment satisfaction, quality of life, JAK inhibitor exposure, endoscopic outcomes, relapse rates, treatment success at Weeks 52 and 104, and identification of predictors of successful treatment discontinuation. Expected Benefits: Reducing exposure to JAK inhibitors may improve the overall safety profile by decreasing treatment-related adverse events while reducing treatment burden for patients with ulcerative colitis. This strategy could support a more individualized and potentially safer long-term management approach for patients in sustained deep remission.
