Background: The Gemini trial failed to detect a significant difference in response rate for patients with ulcerative colitis (UC) randomized to standard (every 8 week) vedolizumab dosing vs escalated (every 4 week) dosing. Subsequent real-world data imply the Gemini trial design may have obscured a benefit of escalated dosing. Aims: We investigated outcomes after vedolizumab dose escalation for patients with UC. We also explored potential clinical predictors of dose escalation requirement. Methods: In this retrospective study, we included patients with UC who received vedolizumab between 1/2017-1/2019. We compared rates of clinical response (decrease in partial Mayo score by ≥ 2) and remission (partial Mayo < 2) for standard vs escalated dosing. Results: Among the 90 patients reviewed, 52 achieved and maintained remission on standard dosing. The average time to remission with standard dosing was 33.3 ± 6.6 weeks. After an average of 56.3 ± 7.4 weeks standard dosing, 24 patients (22 “partial responders” and 2 “non-responders”) were dose-escalated. Of the 22 “partial responders” dose-escalated, 10 (45%) achieved remission, 10 (45%) achieved further improvement. Neither “non-responder” demonstrated further clinical benefit. Prior anti-tumor necrosis factor (anti-TNF) biologic exposure predicted dose escalation requirement (p = 0.008). Patients requiring dose escalation had more severe disease at baseline as measured by both full Mayo (p = 0.009) and partial Mayo scores (p = 0.01). Conclusions: We show dose escalation benefited patients with UC who exhibit a “partial response” to standard dosing. Early vedolizumab dose escalation should be considered in both patients with severe disease and those with prior anti-TNF experience.
