Maintenance treatment with risankizumab was associated with an improvement in coprimary endpoints of clinical remission and endoscopic response in patients with Crohn’s disease compared with placebo.

Risankizumab was effective and well tolerated as induction therapy in patients with moderately to severely active Crohn’s disease, though there were no significant differences in efficacy between 600mg and 1200mg doses.

Upadacitinib Induction and Maintenance Therapy for Crohn’s Disease

N Engl J Med 2023; 388:1966–1980 doi: 10.1056/NEJMoa2212728

Upadacitinib was associated with higher percentages of remission and endoscopic response regardless of previous failure of biologic therapy. This paper reports the Phase 3 efficacy and safety results of upadacitinib in patients with moderate-to-severe Crohn’s disease.

Ozanimod as induction therapy and maintenance therapy for ulcerative colitis

N Engl J Med 2021;385:1280–91 doi: 10.1056/NEJMoa2033617

Patients receiving ozanimod displayed a significant improvement in clinical response and all secondary endpoints during both the 10-week induction and 52-week maintenance study periods. Percentage of patients achieving clinical remission at Weeks 10 and 52 was the primary endpoint.

Etrasimod demonstrated significant efficacy in achieving clinical remission, and was well tolerated compared to placebo in an induction and maintenance therapy.

The results of two induction studies (UC1 and UC2) and a maintenance study (UC3) show upadacitinib superiority to placebo in treating ulcerative colitis (UC). Rates of clinical remission were significantly higher for all upadacitinib doses versus placebo in all three studies.

No new safety signals were found in the three-year safety data on bimekizumab for plaque PsO. Additionally, incidence of oral candidiasis significantly decreased with each subsequent year.

This post-hoc analysis by Baraliakos, et al. found a response in short-term index studies was maintained in the long-term OLE studies, and where no response occurred in the index studies, continued treatment led to a response in a large proportion of patients.

Risankizumab therapy was associated with significant and sustained improvement in multiple disease domains from Week 52 through Week 100, compared with placebo. Kristensen et al. investigated the safety, efficacy and tolerability of 100-week risankizumab therapy in PsA patients with previous inadequate response to ≥1 csDMARD, using data from KEEPsAKE 1 trial.

Significant improvements in overall disease activity, enthesitis and dactylitis, and skin psoriasis were observed by Week 8 and maintained or improved through Week 100 in both guselkumab treatment groups. Coates et al conducted a post-hoc analysis of the Phase 3 DISCOVER-2 trial to investigate the long-term (100-week) efficacy of guselkumab across GRAPPA-identified PsA domains.
