How does Omvoh® (mirikizumab-mrkz) affect quality of life and work productivity in patients with ulcerative colitis?
Patients who received mirikizumab had significantly greater improvements in work productivity and activity impairment and in IBDQ scores than did patients who received placebo.
LUCENT-1 and LUCENT-2 Study Designs
LUCENT-1
LUCENT-1 is a 12-week, phase 3, multicenter, randomized, double-blind, parallel-arm, placebo-controlled study of mirikizumab, a p19-directed anti-interleukin-23 (anti-IL-23) antibody. The study was conducted to evaluate efficacy and safety in adult patients with moderately to severely active ulcerative colitis (UC), with a modified Mayo score of 4 to 9 points and centrally read Mayo endoscopic subscore ≥2, who had an inadequate response, loss of response, or an intolerance to corticosteroids, immunosuppressants, biologic therapies, or tofacitinib.1
A total of 1281 patients were randomized in a 3:1 ratio to receive intravenous (IV) mirikizumab 300 mg or placebo every 4 weeks. Randomization was stratified by
- biologic or tofacitinib failure status
- baseline corticosteroid use
- baseline disease activity as measured by the modified Mayo score, and
- world region.1
LUCENT-2
LUCENT-2 is a 40-week, phase 3, multicenter, randomized, double-blind, parallel-arm, placebo-controlled, maintenance study that evaluated the safety and efficacy of mirikizumab, a p19-directed anti-IL-23 antibody, conducted in adult patients with moderately to severely active UC who completed the LUCENT-1 study.1
A total of 544 patients who received mirikizumab in LUCENT-1 and achieved a clinical response were rerandomized in a 2:1 ratio to receive subcutaneous mirikizumab 200 mg or placebo every 4 weeks for 40 weeks. Randomization was stratified by
- biologic or tofacitinib failure status
- induction remission status
- baseline corticosteroid use, and
- geographic region (North America/Europe/other).1
Work Productivity and Activity Impairment Questionnaire
Work Productivity and Activity Impairment Questionnaire Ulcerative Colitis (WPAI:UC) scores ranging from 0% to 100%, with higher scores indicating higher levels of impairment, were calculated from patient-reported measurements. The overall activity impairment domain included all respondents, and the absenteeism, presenteeism, and work productivity domains included respondents who reported employment at the time of the analyses. At baseline, of 1162 patients, 705 (60.67%) reported employment.2
At week 12 of LUCENT-1, patients who received mirikizumab had significantly greater improvements from baseline in activity impairment (p<.001), absenteeism (p<.05), presenteeism (p<.01), and work productivity (p<.01) than did patients who received placebo (Change From Baseline in Work Productivity and Activity Impairment Questionnaire: Ulcerative Colitis Scores at Week 12 of LUCENT-1 and at Week 40 of LUCENT-2).2
Of the patients who received mirikizumab in LUCENT-1 and achieved a clinical response, those who continued treatment with mirikizumab had significantly greater improvements from induction baseline at week 40 of LUCENT-2 in activity impairment (p<.001), presenteeism (p<.001), and work productivity (p<.001) than did patients who received placebo (Change From Baseline in Work Productivity and Activity Impairment Questionnaire: Ulcerative Colitis Scores at Week 12 of LUCENT-1 and at Week 40 of LUCENT-2).2

Note: The changes from baseline at week 12 of LUCENT-1 and at week 40 of LUCENT-2 were evaluated by analysis of covariance, and stratification factors and baseline scores were used as covariates. Stratification for LUCENT-1 included baseline disease activity, and stratification for LUCENT-2 included the LUCENT-1 clinical remission status.
aOutcomes are change from induction baseline to week 40 of LUCENT-2, for a total of 52 weeks of continuous therapy.
bThe LSM difference is the LSM change from baseline in WPAI:UC scores of participants receiving mirikizumab minus the LSM change from baseline in WPAI:UC scores of participants receiving placebo.

Inflammatory Bowel Disease Questionnaire
The Inflammatory Bowel Disease Questionnaire (IBDQ) measures health-related quality of life, and higher scores indicate better quality of life.3
A minimal clinically important difference (MCID), or IBDQ response, was defined as an improvement from baseline of at least 16 points in the total IBDQ score, and IBDQ remission was defined as a total IBDQ score of at least 170 points.3
At week 12 of LUCENT-1 and at week 40 of LUCENT-2, patients who received mirikizumab had significantly greater improvements from baseline in the IBDQ total and domain scores than did patients who received placebo (p<.001 for all) (Change From Baseline in Inflammatory Bowel Disease Questionnaire Scores at Week 12 of LUCENT-1 and at Week 40 of LUCENT-2).3
Compared with placebo, a significantly greater proportion of patients who received mirikizumab achieved IBDQ response and IBDQ remission at week 12 of LUCENT-1 and at week 40 of LUCENT-2 (p<.001 for all) (Change From Baseline in Inflammatory Bowel Disease Questionnaire Scores at Week 12 of LUCENT-1 and at Week 40 of LUCENT-2).3

Notes:
The IBDQ domains and total scores were evaluated by analysis of variance with modified baseline observation carried forward and adjustment for covariates.
The IBDQ-based measurements for clinical response and remission were analyzed using nonresponder imputation. The common risk difference was the stratification-adjusted difference in the proportion of patients receiving mirikizumab minus the proportion of patients receiving placebo. Stratification for LUCENT-1 included baseline disease activity, and stratification for LUCENT-2 included the LUCENT-1 clinical remission status.
aOutcomes are change from induction baseline to week 40 of LUCENT-2, for a total of 52 weeks of continuous therapy.

cDefined as an improvement of at least 16 points in the total IBDQ score.
