Back to Healio Key takeaways: A post-hoc analysis of 11 trials found upadacitinib and infliximab had the highest symptom improvement rates at 2 weeks among biologic-naive patients with UC. Other advanced therapies had a more gradual onset. Among biologic-naive patients with moderate to severe ulcerative colitis, upadacitinib and infliximab had the quickest onset and highest postinduction response of eight advanced therapies, according to results of a post-hoc analysis. The other therapies had a more gradual onset but exhibited strong efficacy by the end of induction. \u201cWe have all these great new therapies for ulcerative colitis, but their clinical trials used completely different timelines and endpoints, making it impossible to compare them head-to-head,\u201d study author Neeraj Narula, MD, MPH, director of the IBD clinic at McMaster University, told Healio. \u201cOur study pooled individual patient data from 11 major trials to look at them on a more-level playing field.\u201d Diarrhea, urgency and rectal bleeding significantly impair quality of life for patients with moderate to severe UC, and delayed treatment onset can increase risk for complications, according to study background. Achieving symptom relief quickly is a primary treatment goal, but data detailing the speed of onset for available therapies are limited. Narula and colleagues evaluated onset and induction efficacy for eight advanced therapies using data from 3,573 biologic-naive patients (mean age, 40.8 years; 59.2% women; mean disease duration, 6.6 years) treated with standard induction doses for moderate to severe UC. Therapies included adalimumab (n = 338), golimumab (n = 149), infliximab (n = 241), mirikizumab (n = 542), tofacitinib (n = 193), upadacitinib (n = 300), ustekinumab (n = 156) and vedolizumab (n = 431). Researchers also included a placebo group (n = 1,223). Patient-reported outcome-2 (PRO-2) response, defined as at least a 50% reduction in rectal bleeding and stool frequency at 2 weeks, served as the primary outcome. Secondary outcomes included postinduction PRO-2 response and PRO-2 remission at week 2 and at the end of induction. Results showed upadacitinib (65%) and infliximab (36.5%) exhibited the highest week 2 PRO-2 response rates. \u201cIt was fascinating to see the high week 2 response rate from upadacitinib,\u201d Narula said. \u201cIts speed of onset may suggest it should have a role in management of hospitalized colitis patients, although we need more prospective [randomized controlled trial] data vs. infliximab to fully understand its role in this setting.\u201d When compared with infliximab in adjusted analysis, upadacitinib demonstrated significantly higher odds of PRO-2 response (aOR = 3.57; 95% CI, 2.4-6.2). Other therapies appeared significantly less likely than infliximab to demonstrate PRO-2 response at week 2, including mirikizumab (aOR = 0.46; 95% CI, 0.32-0.66), ustekinumab (aOR = 0.6; 95% CI, 0.38-0.96) and adalimumab (aOR = 0.67; 95% CI, 0.46-0.97). \u201cClinicians can use this data to tailor treatment directly to how urgent a patient\u2019s situation is,\u201d Narula said. \u201cIf a patient is suffering severely and we need to keep them out of the hospital right now, upadacitinib or infliximab are the go-to options; if their disease is more stable, we can comfortably opt for therapies with a more gradual onset but perhaps a different safety or convenience profile.\u201d By the end of induction at week 8, upadacitinib (79%) and infliximab (72.6%) continued to demonstrate the highest rates of PRO-2 response. The other therapies had significantly lower odds of postinduction PRO-2 response compared with infliximab (P < .001). PRO-2 remission rates were highest at week 2 for infliximab (34.9%), golimumab (26.9%) and tofacitinib (25.9%). At week 8, ustekinumab (53.9%), infliximab (51.9%) and adalimumab (45.9%) had the highest rates of PRO-2 remission. \u201cThere\u2019s a clear hierarchy when it comes to how fast these drugs provide symptom relief,\u201d Narula said. \u201cUpadacitinib and infliximab are the clear frontrunners for rapid onset, showing significant patient-reported improvement by week 2, though many other therapies definitely catch up by the end of induction.\u201d Study limitations stem from the individual trials, which varied in methodology, duration of induction and assessment intervals. The trials\u2019 strict inclusion criteria also may limit the generalizability of these findings. \u201cMoving forward, we really need prospective, real-world studies to see if these speed-of-onset differences directly translate into other meaningful IBD-related outcomes, such as fewer hospitalizations and less corticosteroid use,\u201d Narula said.
