Abstract

Abstract Background For patients with ulcerative colitis (UC), both subjectively and objectively reported measures are equally important treatment goals. We explored clinical, biological, HRQoL remission and endoscopic improvements as a combined endpoint (CE) from SELECTION (NCT02914522), a phase 2b/3 double-blind trial which assessed the efficacy and safety of filgotinib, a once-daily, oral, Janus 1 kinase preferential inhibitor, for the treatment of UC. Methods In SELECTION, patients with moderately to severely active UC were randomized 2:2:1 to 200mg filgotinib (FIL200), 100mg filgotinib, or placebo (PBO) for an 11-week induction phase followed by a 47-week maintenance period in patients who achieved clinical remission or response.1 We defined a CE as achieving all of the following: 1) clinical remission defined as partial Mayo Score (excluding endoscopy domain) ≤2 and no sub-score >1), 2) biological remission defined as faecal calprotectin <150 µg/g endoscopic improvement defined as Mayo endoscopic sub-score ≤1), 3) Inflammatory Bowel Disease Questionnaire (IBDQ) remission defined as IBDQ >170 and 4) endoscopic improvement defined as Mayo endoscopic sub-score ≤1). We evaluated the CE among patients treated with FIL200 vs placebo in induction (week 10) and maintenance (week 58) phases. Among those achieving the CE, we analysed MCID improvement during induction and decline during maintenance on generic QoL instruments (36-item short-form questionnaire and EuroQol 5-dimension [EQ5D]).2,3,4 Results Overall population included 381 biologic-naïve and 401 biologic-experienced patients undergoing induction, of which 297 subsequently entered maintenance. A higher proportion of patients receiving FIL200 achieved CE than PBO by week 10 in the biologic-naïve induction cohort (17.6% vs 4.41%, p<0.001) and by week 58 in the maintenance cohort (22.1% vs 7.14%, p=0.002) (Table 1). Biologic-naïve CE achievers had higher MCID improvement across all generic QoL scales and domains (Table 2). Patients achieving CE in maintenance experienced a lower proportion of MCID decline in EQ5D utility, and visual analogue scale. Conclusion Treatment with filgotinib resulted in a higher proportion of patients with combined clinical, biological, HRQoL remission and endoscopic improvements. Among patients achieving this combined composite endpoint, clinically meaningful improvements were observed in their overall quality of life. Holistic assessment of several subjective and objective measures may help achieve better outcomes in UC. References 1. Feagan BF, et al. Lancet 2021;397:2372–84. 2.

Not 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.
