Introduction: This analysis evaluated if the addition of BU improvement to clinical response or remission was associated with better work productivity from mirikizumab (miri) Phase 3 LUCENT-1 and LUCENT-2 trials in patients with moderately-to-severely active ulcerative colitis (UC).

Methods: In LUCENT-1, patients were randomized 3:1 to induction miri 300mg intravenous or placebo every four weeks (Q4W). Patients who achieved clinical response to miri at week 12 (W12) were re-randomized 2:1 to maintenance subcutaneous injection of miri 200mg or placebo Q4W for 40 weeks in LUCENT-2 [52 weeks (W52) continuous treatment]. Clinical response and remission were assessed along with change from baseline (BL) in Work Productivity and Activity Impairment Questionnaire UC (WPAI:UC) domain scores. BU was assessed using the Urgency Numeric Rating Scale (UNRS), with both BU CMI (≥3-point change) and BU remission (UNRS score of 0 or 1), measured in patients with a BL UNRS of ≥3. The association between BU (CMI or remission) with the change of WPAI:UC was evaluated using analysis of variance among patients with BL UNRS ≥3 who achieved clinical response. This analysis was repeated among patients who achieved clinical remission.

Results: The addition of BU CMI was positively associated with reduction of activity impairment, presenteeism, and overall work impairment in patients who achieved clinical response or remission at both W12 and W52 (p< 0.005)(Table 1). Achieving clinical response and BU remission was significantly associated with greater reduction of activity impairment, presenteeism, and overall work impairment vs patients with clinical remission only at both W12 and W52 (p< 0.01). The combined improvement of achieving both clinical remission and BU remission was significantly associated with higher reduction in activity impairment at W12 (-36.1% vs -27.3%; p=0.0147) and overall work impairment at W52 (-39.9% vs -29.8%; p=0.0394). Patients who achieved both clinical response or clinical remission and BU CMI or BU remission did not show a significant difference in absenteeism compared to those who achieved clinical response or remission alone.

Discussion: Among patients with UC from miri phase 3 trials, the addition of BU (CMI or remission) to the achievement of clinical response or remission was associated with reduction of WPAI:UC components: activity impairment, presenteeism, and overall work impairment.
