Abstract Background Health-related quality of life (HRQOL) is reduced in patients (pts) with ulcerative colitis (UC). We report on the HRQOL benefits of maintenance treatment with upadacitinib (UPA), a selective and reversible Janus kinase inhibitor, in pts with moderately to severely active UC in the Phase, 3 multicentre, randomised, double-blind U-ACHIEVE maintenance study (NCT02819635). Methods This study included a primary analysis of, 451 pts who achieved clinical response following treatment with UPA, 45 mg once daily (QD) in two replicate, 8-week induction studies, U-ACHIEVE induction, and U-ACCOMPLISH (NCT03653026). In U-ACHIEVE maintenance, pts from both induction studies were re-randomised, 1:1:1 to receive QD UPA, 15 mg, UPA, 30 mg, or PBO. HRQOL outcomes evaluated included the percent of pts reporting a clinically meaningful within-person change (MWPC) from induction baseline to Week, 0 (maintenance baseline) and Week, 52 (end of maintenance) in a broad range of HRQOL measures, including Inflammatory Bowel Disease Questionnaire (IBDQ), Work Productivity and Impairment Questionnaire (WPAI), Short Form, 36 (SF-36), European Quality of Life-5 Dimensions, 5 Levels (EQ-5D-5L), and Ulcerative Colitis Symptoms Questionnaire (UC-SQ). Results A total of, 149, 148, and, 154 pts received PBO, UPA, 15 mg, and UPA, 30 mg QD, respectively, during maintenance. At Week, 0 of the maintenance study, there were no significant differences between UPA and PBO treatment groups in the percentage of pts reporting MWPC relative to induction baseline for most pt-reported outcomes (PROs) as all pts enrolled in maintenance were UPA clinical responders during IP. For IBDQ, a significantly greater proportion of pts achieved MWPC criteria (p<0.001) with UPA, 15 mg (68.9%) and UPA, 30 mg (78.6%) vs, 39.6% for PBO at Week, 52 (Figure, 1). Also, a significantly greater proportion of pts treated with either, 15 mg or, 30 mg UPA dosage vs PBO over, 52 weeks achieved MWPC for the WPAI domains (p≤0.01) of overall work improvement, presenteeism, and activity impairment (Figure, 2), in both physical and mental component summaries of SF-36 (p<0.001, Figure, 3), in EQ-5D-5L (p<0.001, Figure, 4), and in UC-SQ (p<0.001). A numerically greater proportion of pts receiving UPA, 30 mg vs, 15 mg achieved MWPC in most PROs at Week 52. Conclusion A significantly higher percentage of pts with moderately to severely active UC who responded to UPA induction therapy maintained clinically meaningful improvements with UPA, 15 mg of, 30 mg compared to PBO consistently across a broad range of HRQOL outcomes after, 52 weeks of maintenance treatment. These HRQOL aspects include IBD symptoms (IBDQ, UC-SQ), work productivity (WPAI), physical and mental functioning (SF-36), and general well-being (IBDQ, EQ-5D).

Abstract Background Anaemia is a frequent complication in patients with Crohn’s disease and ulcerative colitis (UC), and patients who respond to treatment generally show improvement in anaemia. Decrease in haemoglobin (Hgb) levels and anaemia may be associated with Janus kinase (JAK) inhibitors. Upadacitinib (UPA), an oral JAK1 selective inhibitor, has demonstrated favourable dose-dependent efficacy in patients with moderately to severely active UC.1 This analysis of data from the U-ACHIEVE study addressed effects of UPA treatment on Hgb levels in patients with UC. Methods U-ACHIEVE (NCT02819635) was a randomised, double-blind, placebo (PBO)-controlled phase 2b clinical trial. Adults with moderately to severely active UC were randomised to receive 7.5, 15, 30, or 45 mg UPA or PBO once daily (QD) for 8 weeks. Hgb levels were measured for all groups at baseline (BL) and weeks 2, 4, 6, and 8. Mean change from BL was calculated for each group. p-values for comparison between UPA and PBO groups were calculated using one-way ANOVA; no multiplicity adjustment was applied. Percentage of patients with Hgb values grade 2 (15–20 g/l Hgb decrease from BL), grade 3 (<80 g/l Hgb level or 21–29 g/l Hgb decrease from BL), and grade 4 (<70 g/l Hgb level or >29 g/l Hgb decrease BL) anaemia were determined for all treatment groups using the Common Terminology Criteria for Adverse Events version 5. Adverse events (AE) were reported by investigators. Results Included in the analysis were 250 patients (mean age ± SD, 42.3 ± 14.2 years; disease duration, 8.2 ± 2.5 years). At BL, most treatment groups had similar mean Hgb levels, except for the 15 mg UPA group, which had significantly lower Hgb levels vs. PBO group (Table). Increased or stable mean levels of Hgb at week 8 vs. BL were observed in most UPA treatment groups. The PBO group had the greatest decrease in Hgb vs. BL at week 8 compared with UPA treatment groups (Figure). Grade ≥2 anaemia was reported in 17.4% of patients receiving PBO and 14.4% of all patients receiving UPA (14.9%, 12.2%, 12.0%, and 17.9% of patients receiving 7.5, 15, 30, and 45 mg UPA, respectively). Grade ≥3 anaemia was reported in 8.7% of patients receiving PBO and 5% of all patients receiving UPA (6.4%, 6.1%, 6.0%, and 1.8% of patients receiving 7.5, 15, 30, and 45 mg UPA, respectively). One subject receiving 7.5 mg QD UPA had grade 4 anaemia. AE of anaemia was reported in 6.5% of patients receiving PBO and in 2.1%, 8.2%, and 3.8% of patients receiving 7.5, 15, and 30 mg UPA, respectively, but not in the 45 mg UPA group. Conclusion Decreased Hgb levels over time were observed more frequently in the PBO group. The maintenance of Hgb levels in patients receiving UPA was likely because of improvement of underlying UC.
