Item Comparative Safety and Effectiveness of Vedolizumab to Tumor Necrosis Factor Antagonist Therapy for Ulcerative Colitis(Elsevier, 2022) Lukin, Dana; Faleck, David; Xu, Ronghui; Zhang, Yiran; Weiss, Aaron; Aniwan, Satimai; Kadire, Siri; Tran, Gloria; Rahal, Mahmoud; Winters, Adam; Chablaney, Shreya; Koliani-Pace, Jenna L.; Meserve, Joseph; Campbell, James P.; Kochhar, Gursimran; Bohm, Matthew; Varma, Sashidhar; Fischer, Monika; Boland, Brigid; Singh, Siddharth; Hirten, Robert; Ungaro, Ryan; Lasch, Karen; Shmidt, Eugenia; Jairath, Vipul; Hudesman, David; Chang, Shannon; Swaminath, Arun; Shen, Bo; Kane, Sunanda; Loftus, Edward V., Jr.; Sands, Bruce E.; Colombel, Jean-Frederic; Siegel, Corey A.; Sandborn, William J.; Dulai, Parambir S.; Medicine, School of MedicineBackground & aims: We aimed to compare safety and effectiveness of vedolizumab to tumor necrosis factor (TNF)-antagonist therapy in ulcerative colitis in routine practice. Methods: A multicenter, retrospective, observational cohort study (May 2014 to December 2017) of ulcerative colitis patients treated with vedolizumab or TNF-antagonist therapy. Propensity score weighted comparisons for development of serious adverse events and achievement of clinical remission, steroid-free clinical remission, and steroid-free deep remission. A priori determined subgroup comparisons in TNF-antagonist-naïve and -exposed patients, and for vedolizumab against infliximab and subcutaneous TNF-antagonists separately. Results: A total of 722 (454 vedolizumab, 268 TNF antagonist) patients were included. Vedolizumab-treated patients were more likely to achieve clinical remission (hazard ratio [HR], 1.651; 95% confidence interval [CI], 1.229-2.217), steroid-free clinical remission (HR, 1.828; 95% CI, 1.135-2.944), and steroid-free deep remission (HR, 2.819; 95% CI, 1.496-5.310) than those treated with TNF antagonists. Results were consistent across subgroup analyses in TNF-antagonist-naïve and -exposed patients, and for vedolizumab vs infliximab and vs subcutaneous TNF-antagonist agents separately. Overall, there were no statistically significant differences in the risk of serious adverse events (HR, 0.899; 95% CI, 0.502-1.612) or serious infections (HR, 1.235; 95% CI, 0.608-2.511) between vedolizumab-treated and TNF-antagonist-treated patients. However, in TNF-antagonist-naïve patients, vedolizumab was less likely to be associated with serious adverse events than TNF antagonists (HR, 0.192; 95% CI, 0.049-0.754). Conclusions: Treatment of ulcerative colitis with vedolizumab is associated with higher rates of remission than treatment with TNF-antagonist therapy in routine practice, and lower rates of serious adverse events in TNF-antagonist-naïve patients.Item Efficacy and Safety of Mirikizumab in a Randomized Phase 2 Study of Patients With Crohn’s Disease(Elsevier, 2022-02) Sands, Bruce E.; Peyrin-Biroulet, Laurent; Kierkus, Jaroslaw; Higgins, Peter D.R.; Fischer, Monika; Jairath, Vipul; Hirai, Fumihito; D’Haens, Geert; Belin, Ruth M.; Miller, Debra; Gomez-Valderas, Elisa; Naegeli, April N.; Tuttle, Jay L.; Pollack, Paul F.; Sandborn, William J.; Medicine, School of MedicineBackground Mirikizumab is a humanized monoclonal antibody targeting interleukin 23p19 with demonstrated efficacy in psoriasis and ulcerative colitis. We investigated the safety and efficacy of mirikizumab in patients with moderate-to-severe Crohn’s disease (CD). Methods Patients (N = 191) were randomized (2:1:1:2) to receive placebo (PBO), 200, 600, or 1000 mg mirikizumab, administered intravenously (IV) every 4 weeks. Patients who received mirikizumab and achieved ≥1 point improvement in Simple Endoscopic Score-CD at Week 12 (rerandomized maintenance cohort) were rerandomized to continue their induction IV treatment (combined IV groups [IV-C]) or receive 300 mg mirikizumab subcutaneously (SC) every 4 weeks. Nonrandomized maintenance cohort included endoscopic nonimprovers (1000 mg) and PBO patients (PBO/1000 mg) who received 1000 mg mirikizumab IV from Week 12. The primary objective was to evaluate superiority of mirikizumab to PBO in inducing endoscopic response (50% reduction from baseline in Simple Endoscopic Score-CD) at Week 12. Results At Week 12, endoscopic response was significantly higher by the predefined 2-sided significance level of 0.1 for all mirikizumab groups compared with PBO (200 mg: 25.8%, 8/31, 95% confidence interval [CI], 10.4–41.2, P = .079; 600 mg: 37.5%, 12/32, 95% CI, 20.7–54.3, P = .003; 1000 mg: 43.8%, 28/64, 95% CI, 31.6–55.9, P < .001; PBO: 10.9 %, 7/64, 95% CI, 3.3–18.6). Endoscopic response at Week 52 was 58.5% (24/41) and 58.7% (27/46) in the IV-C and SC groups, respectively. Frequencies of adverse events (AE) in the mirikizumab groups were similar to PBO. Through Week 52, frequencies of treatment-emergent AEs were similar across all groups. Frequencies of serious AE and discontinuations due to AE were higher in the nonrandomized maintenance cohort. Conclusion Mirikizumab effectively induced endoscopic response after 12 weeks in patients with moderate-to-severe CD and demonstrated durable efficacy to Week 52.
