DOP014 Efficacy and safety up to 3 years of risankizumab maintenance treatment in patients with moderately to severely active ulcerative colitis: interim results from phase 3 COMMAND open-label extension study
Bibliographic record
Abstract
Abstract Background Risankizumab (RZB), a high-affinity humanised IgG1 monoclonal antibody targeting interleukin-23 p19, has shown sustained efficacy and an acceptable safety profile for patients (pts) with ulcerative colitis (UC).1 This interim analysis reports efficacy data at week (wk) 0 and wk 96, as well as safety data of the COMMAND (NCT03398135) open-label extension (OLE). Methods The COMMAND OLE enrolled pts who completed 52-wks maintenance dosing in the COMMAND substudies or entered directly from the induction study.1 All pts received RZB180 subcutaneous (SC) starting at OLE wk 0, except pts who had prior rescue therapy (single RZB 1200 mg intravenous [IV] dose then RZB360 Q8w) who continued RZB360 in the OLE. The OLE was not designed to compare RZB180 and RZB360 groups. The data cut-off date for this interim analysis was as of June 30, 2024. Efficacy endpoints assessed were clinical remission (CR) per AMS, clinical response per AMS, endoscopic improvement, endoscopic remission, and corticosteroid-free CR per Partial AMS up to wk 96. Data are reported as observed prior to RZB rescue therapy during OLE. The safety analysis also includes pts who directly entered the OLE from induction; presented as events/100 pt years (E/100 PY). Results Of the pts who entered the OLE (RZB180, N = 701; RZB360, N = 302), approximately 40% of pts had the opportunity to reach OLE wk 96 as of the cut-off date. At OLE wk 0 and 96, a similar proportion of patients in the RZB180 group achieved clinical and endoscopic outcomes (Figure 1A). In the RZB360 group, the percent of pts achieving clinical and endoscopic endpoints increased from OLE wk 0 through OLE wk 96 (Figure 1B). Similar rates of serious AEs, severe AEs, and AEs leading to discontinuation of study drug were reported in the RZB180 group and the RZB360 group with no new safety risks identified (Table 1). Conclusion In this interim analysis of the OLE, a sustained benefit was observed with long-term RZB treatment up to 96 wks. The long-term safety profile for RZB remains consistent and supports the long-term use. References 1. Louis E et al. JAMA 2024;332(11):881-897

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
