Resolving Histological Inflammation in Ulcerative Colitis With Mirikizumab in the LUCENT Induction and Maintenance Trial Programmes.

ABSTRACT:

Background and aims

To evaluate the effect of mirikizumab, a p19-targeted anti-interleukin-23, on histological and/or endoscopic outcomes in moderately-to-severely active ulcerative colitis [UC].

Methods

Endoscopic remission [ER], histological improvement [HI], histological remission [HR], histological-endoscopic mucosal improvement [HEMI], and histological-endoscopic mucosal remission [HEMR] were assessed at Week [W]12 [LUCENT-1: N = 1162, induction] and W40 [LUCENT-2: N = 544, maintenance] for patients randomised to mirikizumab or placebo. Analyses were performed to evaluate predictors of: HEMI at W12 with mirikizumab and HEMR at W40 in patients re-randomised to subcutaneous [SC] mirikizumab; associations between W12 histological/endoscopic endpoints and W40 outcomes in mirikizumab responders re-randomised to mirikizumab SC; and associations between W40 endoscopic normalisation [EN] with/without HR.

Results

Significantly more patients treated with mirikizumab achieved HI, HR, ER, HEMI, and HEMR vs placebo [p <0.001], irrespective of prior biologic/tofacitinib failure [p <0.05]. Lower clinical baseline disease activity, female sex, no baseline immunomodulator use, and no prior biologic/tofacitinib failure were predictors of HEMI at W12 [p <0.05]. Corticosteroid use and longer disease duration were negative predictors of achieving HEMR at W40 [p <0.05]. W12 HI, HR, or ER was associated with W40 HEMI or HEMR [p <0.05]; ER at W12 was associated with clinical remission [CR] [p <0.05] and corticosteroid-free remission [CSFR] at W40 [p = 0.052]. HR and HEMR at W12 were associated with CSFR, CR, and symptomatic remission at W40. Alternate HEMR [EN + HR] at W40 was associated with bowel urgency remission at W40 [p <0.05].

Conclusions

Early resolution of endoscopic and histological inflammation with mirikizumab is associated with better UC outcomes. Clinicaltrials.gov: LUCENT-1, NCT03518086; LUCENT-2, NCT03524092.

Project description:BackgroundMirikizumab, an anti-IL-23p19 antibody, demonstrated efficacy in phase 3, randomized, double-blind, placebo-controlled LUCENT-1 (induction/NCT03518086) and LUCENT-2 (maintenance/NCT03524092) ulcerative colitis (UC) studies. We evaluated the effect of mirikizumab on quality-of-life (QoL) outcomes in these studies.MethodsIn LUCENT-1, 1162 patients with moderately-to-severely active UC were randomized 3:1 to receive mirikizumab 300 mg intravenous or placebo every 4 weeks (Q4W) for 12 weeks. In LUCENT-2, mirikizumab induction responders (N = 544) were re-randomized 2:1 to receive mirikizumab 200 mg subcutaneous or placebo Q4W through week (W) 40 (W52 of treatment). QoL was assessed at W12 and W52 using patient-reported outcomes. Treatments were statistically compared using analysis of covariance model (continuous outcomes) and Cochran-Mantel-Haenszel test (binary outcomes).ResultsAt W12 and W52, mirikizumab showed significant improvement in Inflammatory Bowel Disease Questionnaire (IBDQ) total and domain scores (P < .001); 36-Item Short Form Health Survey (SF-36) Physical Component Summary (PCS), Mental Component Summary (MCS), and domain scores (P < .05); EQ-5D-5L scores (P < .001); Work Productivity and Activity Impairment Questionnaire (UC) scores (P < .05); Patient Global Rating of Severity (P < .001); and Patient Global Rating of Change (P < .01) scores. A significantly higher proportion of mirikizumab-treated patients achieved IBDQ response (W12: 72.7% vs 55.8%; W52: 79.2% vs 49.2%; P < .001), IBDQ remission (W12: 57.5% vs 39.8%; W52: 72.3% vs 43.0%; P < .001), and clinically important improvements in PCS (W12: 50.6% vs 41.5%; W52: 61.9% vs 36.9%; P < .01) and MCS (W12: 44.2% vs 37.8%; W52: 51.2% vs 34.6%; P < .05) scores.ConclusionsMirikizumab improved QoL in patients with moderately-to-severely active UC in phase 3 LUCENT-1 and LUCENT-2 studies.Clinical trials registration numberLUCENT-1: NCT03518086; LUCENT-2: NCT03524092.
