P678 Long-term efficacy, safety and health-related quality of life in patients who achieved comprehensive disease control with filgotinib in SELECTION: analysis of ~3 years in SELECTIONLTE
Bibliographic record
Abstract
Abstract Background Filgotinib (FIL), an oral, once-daily, Janus kinase 1 inhibitor, was approved for Ulcerative Colitis (UC) treatment after the phase 2b/3 SELECTION trial (NCT02914522). In SELECTION, a greater proportion of FIL200 mg (FIL200)-treated than placebo-treated patients achieved comprehensive disease control (CDC), a stringent multi-component endpoint. We examined the long-term outcomes of achieving CDC in patients continuing on FIL200 in the ongoing long-term extension (LTE) study SELECTIONLTE (NCT02914535). Methods This interim analysis included adult patients with UC who completed SELECTION and received ≤144 weeks of FIL200 in the LTE (up to data cut-off 24/02/22). CDC (biomarker remission, endoscopic improvement, IBDQ remission and partial Mayo Clinic Score [pMCS] remission achieved concurrently) was assessed at SELECTION week 58 (LTE baseline [BL]). Mean pMCS and IBDQ score, use of corticosteroids (CS) and incidence of TEAEs and serious TEAEs in the LTE were compared between SELECTION CDC achievers and non-achievers. A mixed model for repeated measures was fitted on pMCS and IBDQ score, with CDC achiever status, study visit and the interaction between CDC achiever status and study visit as fixed effects; p values were nominal. Results We analysed 148 patients (CDC achievers, n=41; CDC non-achievers, n=107). Mean pMCS was stable in CDC achievers (0.44, LTE BL; 0.50, LTE week 144) and decreased in CDC non-achievers (1.49, LTE BL; 0.77, LTE week 144; Figure). Mean IBDQ score was stable in CDC achievers (204.05, LTE BL; 197.21, LTE week 144) and increased in CDC non-achievers (181.55, LTE BL; 196.37, LTE week 144; Figure). There was a significant beneficial effect of achieving CDC on pMCS and IBDQ score overall (pMCS: fixed effect estimate: −0.5542, p=0.0025; IBDQ score: fixed effect estimate: 13.1585, p=0.0042). There was a significant interaction between achieving CDC and study visit for IBDQ score (p=0.0183), with the benefit of achieving CDC lessening by week 144. Generally, a lower proportion of CDC achievers used CS than non-achievers; 2.4–7.3% of CDC achievers used CS vs 1.9–15.9% of CDC non-achievers. Incidence of TEAEs and serious TEAEs were stable over time and similar between CDC achievers and non-achievers. Conclusion Follow-up for ~3 years showed high levels of long-term benefit with continued FIL200 treatment. Achieving comprehensive disease control at the end of the randomized trial with FIL200 was associated with long-term efficacy, improved HRQoL and low overall use of CS. This may demonstrate the value of filgotinib-induced achievement of CDC in UC disease course. The safety profile of FIL200 was consistent between CDC achievers and non-achievers, suggesting an acceptable long-term benefit–risk profile.

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.
