Introduction

Ulcerative colitis (UC) is associated with symptoms that may considerably impair patients’ health-related quality of life (HRQoL). Long-term treatment goals established in STRIDE-II include the recuperation of HRQoL in patients with active UC.¹ This post-hoc analysis evaluated the impact of Risankizumab (RZB) as induction and maintenance therapy on normalisation of HRQoL in patients with moderate to severe UC.

Aims & Methods

This study evaluated data from two double-blind, Phase 3 trials, INSPIRE (induction: NCT03398148) and COMMAND (maintenance: NCT03398135). During induction, patients were randomised 2:1 to receive intravenous (IV) RZB 1200 mg or placebo (PBO) at Weeks 0, 4, and 8. Those with a clinical response based on Adapted Mayo score were randomised 1:1:1 to subcutaneous (SC) RZB 180 mg, RZB 360 mg, or PBO (RZB withdrawal) every 8 weeks for 52 weeks of maintenance. The proportion of patients achieving normalisation of individual HRQoL outcomes, per literature-based normative value threshold, was assessed at baseline and Weeks 12 and 52: FACIT-Fatigue score; IBDQ score; WPAI-UC (overall work impairment, work time missed, impairment while working, activity impairment); SF-36 PCS; SF-36 MCS; EQ-5D-5L VAS; and EQ-5D-5L index. A composite endpoint was determined to evaluate patients achieving normalisation of all HRQoL outcomes. Adjusted treatment differences between RZB and PBO were analysed using Mantel-Haenszel common rate difference. P values were calculated using Cochran-Mantel-Haenszel test and adjusted for strata.

Results

At Week 12, for RZB 1200 mg IV (n=650) vs PBO (n=325), more patients achieved normalisation of each individual HRQoL outcome (p<=0.01) (Table 1). For RZB SC 180 mg (n=179) and 360 mg (n=186), more patients achieved normalisation of FACIT-fatigue, IBDQ, and SF-36 PCS vs PBO at Week 52 (p<=0.05). More patients also achieved normalisation of all WPAI-UC scores with RZB 180 mg SC vs PBO (p<=0.05), excluding overall work impairment. For SF-36 MCS and both EQ-5D-5L scores, more patients achieved normalisation with RZB 180 mg SC vs PBO (p<=0.05), but not with RZB 360 mg SC. Normalisation of the composite HRQoL score was achieved by more patients with all doses of RZB vs PBO at Weeks 12 (RZB 1200 mg: 12.5%; PBO: 4.9%) and 52 (RZB 360 mg: 20.4%; RZB 180 mg: 21.2%; PBO: 10.9%) (p<=0.05).

Conclusion

RZB shows greater normalisation of HRQoL compared to PBO, with results seen early during induction and subsequently continued through maintenance. These results indicate that the long-term treatment goal of HRQoL normalisation in patients with moderately to severely active UC may be achievable with RZB.
