Early and Sustained Symptom Control with Mirikizumab in Patients with Ulcerative Colitis in the Phase 3 LUCENT Program.

BACKGROUND AND AIMS: Ulcerative colitis (UC), a chronic inflammatory bowel disease, may manifest with symptoms of increased stool frequency (SF), rectal bleeding (RB), bowel urgency (BU), abdominal pain (AP), and fatigue. Mirikizumab, an anti-IL-23p19 antibody, demonstrated efficacy and safety in patients with moderately to severely active UC in the LUCENT Phase 3 trials. We evaluated mirikizumab's efficacy in achieving symptom control and time to symptom improvement during induction, maintenance of sustained symptom control, "comprehensive symptom control", defined according to a combination of individual patient-reported outcomes, and prognostic baseline indicators of early symptomatic remission at week 4. METHODS: The results of LUCENT-1/-2 have previously been reported. Treatment differences for symptomatic endpoints were compared over 52 weeks versus placebo (PBO) and comprehensive symptomatic endpoints at 12 and 52 weeks of continuous treatment. Subgroup analyses were conducted for prior biologic or tofacitinib treatment failure. Prognostic analyses were run using regression analysis. RESULTS: By Week (W)2, mirikizumab-treated patients achieved greater reductions in SF, RB, BU, and fatigue versus PBO. At W4, there was a higher rate of AP improvement. At W12, a greater proportion of mirikizumab-treated patients achieved symptomatic remission, RB remission, SF remission, and BU remission/clinically meaningful improvement. Mirikizumab-treated patients sustained symptom control versus placebo patients in maintenance until W52. This treatment effect was shown in patients regardless of prior biologic or tofacitinib failure. Additionally, mirikizumab achieved comprehensive symptom control versus PBO at W12 and W52. CONCLUSIONS: Mirikizumab demonstrated efficacy in achieving and sustaining symptom control and comprehensive symptom control over 52 weeks. [NCT03518086; NCT03524092].

Patient and Health Care Professional Perceptions of the Experience and Impact of Symptoms of Moderate-to-Severe Crohn's Disease in US and Europe: Results from the Cross-Sectional CONFIDE Study.

BACKGROUND: Crohn's disease (CD) significantly affects patients' health-related quality of life and well-being. AIMS: Communicating Needs and Features of IBD Experiences (CONFIDE) survey explores the experience and impact of moderate-to-severe CD symptoms on patients' lives and identifies communication gaps between patients and health care professionals (HCPs). METHODS: Online, quantitative, cross-sectional surveys of patients, and HCPs were conducted in the United States (US), Europe (France, Germany, Italy, Spain, United Kingdom), and Japan. Criteria based on previous treatment, steroid use, and/or hospitalization defined moderate-to-severe CD. US and Europe data are presented as descriptive statistics. RESULTS: Surveys were completed by 215 US and 547 European patients and 200 US and 503 European HCPs. In both patient groups, top three symptoms currently (past month) experienced were diarrhea, bowel urgency, and increased stool frequency, with more than one-third patients wearing diaper/pad/protection at least once a week in past 3 months due to fear of bowel urgency-related accidents. HCPs ranked diarrhea, blood in stool, and increased stool frequency as the most common symptoms. Although 34.0% US and 27.2% European HCPs ranked bowel urgency among the top five symptoms affecting patient lives, only 12.0% US and 10.9% European HCPs ranked it among top three most impactful symptoms on treatment decisions. CONCLUSION: Bowel urgency is common and impactful among patients with CD in the US and Europe. Differences in patient and HCP perceptions of experiences and impacts of bowel urgency exist, with HCPs underestimating its burden. Proactive communication between HCPs and patients in clinical settings is crucial for improving health outcomes in patients with CD.

Two-Year Efficacy and Safety of Mirikizumab Following 104 Weeks of Continuous Treatment for Ulcerative Colitis: Results From the LUCENT-3 Open-Label Extension Study.

BACKGROUND: Mirikizumab, a p19-directed interleukin-23 monoclonal antibody, is efficacious in inducing clinical remission at week 12 (W12) and maintaining clinical remission at W52 in patients with moderately to severely active ulcerative colitis. Results are presented from the open-label extension study through W104. METHODS: Clinical, symptomatic, quality-of-life, and adverse event outcomes are reported for mirikizumab induction responders and extended induction responders, including biologic-failed patients, who entered LUCENT-3, with data shown for W52 maintenance responders or remitters. Discontinuations or missing data were handled by nonresponder imputation (NRI), modified NRI (mNRI), and observed case (OC). RESULTS: Among W52 mirikizumab responders, clinical response at W104 was 74.5%, 87.2%, and 96.7% and clinical remission was 76.6%, 89.0%, and 98.3% for NRI, mNRI, and OC, respectively. Among W52 mirikizumab remitters, clinical response at W104 was 54.0%, 62.8%, and 70.1% and clinical remission was 65.6%, 76.1%, and 84.2%. Using mNRI, remission rates at W104 for W52 clinical remitters were 74.7% corticosteroid-free, 79.5% endoscopic, 63.9% histologic-endoscopic mucosal remission, 85.9% symptomatic, 59.8% bowel urgency, 80.5% Inflammatory Bowel Disease Questionnaire (using NRI), 71.2% histologic-endoscopic mucosal improvement, and 77.5% bowel urgency improvement. Previous biologic-failed vs not-biologic-failed patient data were generally similar. Extended induction mNRI clinical response was 81.9%. Serious adverse events were reported in 5.2% of patients; 2.8% discontinued treatment due to adverse events. CONCLUSIONS: Endoscopic, histologic, symptomatic, and quality-of-life outcomes support the long-term benefit of mirikizumab treatment up to 104 weeks in patients with ulcerative colitis, including biologic-failed patients, with no new safety concerns.

Long-term clinical response/remission, endoscopic, histologic, and symptomatic data from an open-label study in patients with moderately to severely active ulcerative colitis demonstrate that 2-year continuous mirikizumab treatment maintained clinical remission in a majority of induction clinical responders, regardless of previous biologic failure status.

Patient Perspectives of Bowel Urgency and Bowel Urgency-Related Accidents in Ulcerative Colitis and Crohn's Disease.

BACKGROUND: Bowel urgency is bothersome in patients with ulcerative colitis (UC) or Crohn's disease (CD) and impacts their well-being but remains underappreciated in clinical trials and during patient-healthcare provider interactions. This study explored the experiences of bowel urgency and bowel urgency-related accidents to identify the concepts most relevant and important to patients. METHODS: Adults with a diagnosis of moderate-to-severe UC or CD for ≥6 months and experience of bowel urgency in the past 6 months were included. Qualitative, semi-structured interviews were conducted via telephonic/Web-enabled teleconference. Interview transcripts were coded and analyzed in ATLAS.ti 9 using a systematic thematic analysis. RESULTS: In total, 30 participants with UC or CD (n = 15 each) (mean age 52 and 50 years, respectively) participated in the interviews. The majority of participants were receiving biologic and/or conventional therapy (80% and 87%, respectively). Most participants with UC (87%) and all with CD experienced bowel urgency-related accidents. The most frequently reported symptoms co-occurring with bowel urgency were abdominal pain, fatigue, and abdominal cramping. Abdominal pain and abdominal cramping were the most bothersome co-occurring symptoms of bowel urgency and bowel urgency-related accidents. In both groups, participants reported decreased frequency of bowel urgency and not wanting to experience bowel urgency-related accidents at all as a meaningful improvement. CONCLUSIONS: Participants with UC or CD expressed bowel urgency and bowel urgency-related accidents to be bothersome and impactful on their daily lives despite use of biologic and/or conventional therapy. These findings underscore the need for development of patient-reported outcome measures to assess bowel urgency in clinical settings.

Bowel urgency and bowel urgency-related accidents are accompanied by several bothersome symptoms and considerably impact patients' quality of life, highlighting the need to develop a patient-reported outcome measure for assessing and addressing bowel urgency in clinical settings.

Early Use of Biologics Reduces Healthcare Costs in Crohn's Disease: Results from a United States Population-Based Cohort.

BACKGROUND: Early initiation of biologics in moderate-to-severe Crohn's disease (CD) may significantly alter disease progression, resulting in better patient outcomes. Limited real-world data exist on the impact of early biologic use in patients with CD in the United States. AIMS: We aimed to characterize biologic initiation and subsequent healthcare resource utilization (HCRU) in adults with recently diagnosed CD. METHODS: Patients with CD who initiated biologic treatment within 2 years of diagnosis (index date) were identified from medical and pharmacy claims (Merative L.P. MarketScan Database from 2010 to 2016) and classified as early (≤ 12 months post-index) or late (> 12-24 months post-index) biologic initiators. Propensity score matching balanced patient characteristics up to 1 year post-index. Differences in HCRU frequency and costs 1-2 years post-index were compared between the matched groups. RESULTS: After propensity score matching, 672 pairs of early and late biologic initiators were identified. Patients who initiated biologics early had fewer outpatient visits (15.5 vs 19.8, 95% confidence interval [CI] for difference: 2.7, 6.1) and lower total medical costs ($13,646.20 vs $22,180.70, 95% CI for difference: 4748.9, 12,320.1) 1-2 years post-index than late biologic initiators. Early biologic initiators had higher medication costs 1-2 years post-index ($33,766.30 vs $30,580.70, 95% CI: 546.1, 5825.1) but lower combined medical and medication costs ($47,412.50 vs $52,761.50, 95% CI: 801.5, 9896.40). CONCLUSIONS: While biologic treatments are costly, patients initiating biologics sooner after diagnosis appear to have better HCRU outcomes and require fewer healthcare resources at 1-2 years post-index, potentially leading to overall cost savings.

Rectal Urgency Among Patients With Ulcerative Colitis or Crohn's Disease: Analyses from a Global Survey.

Background: Rectal urgency is a common but under-reported inflammatory bowel disease (IBD) symptom. The present study assessed the prevalence of rectal urgency and its association with disease activity and patient-reported outcomes (PROs) among patients with ulcerative colitis (UC) or Crohn's disease (CD) in a real-world setting. Methods: Data were drawn from the 2017-2018 Adelphi IBD Disease Specific Programme™, a multi-center, point-in-time survey of gastroenterologists and consulting adult patients with UC or CD in France, Germany, Italy, Spain, the United Kingdom, and the United States. Gastroenterologists completed patient record forms and patients completed self-reported forms. Analyses were conducted separately for patients with UC or CD. Patient demographics, clinical characteristics, disease activity, symptoms, and PROs were compared between patients with and without rectal urgency. Results: In total, 1057 patients with UC and 1228 patients with CD were included. Rectal urgency was reported in 20.2% of patients with UC and 16.4% with CD. Patients with rectal urgency were more likely to have moderate or severe disease (UC or CD: P < .0001), higher mean Mayo score (UC: P < .0001), higher mean Crohn's Disease Activity Index score (CD: P < .0001), lower Short IBD Questionnaire scores (UC or CD: P < .0001), and higher work impairment (UC: P < .0001; CD: P = .0001) than patients without rectal urgency. Conclusions: Rectal urgency is a common symptom associated with high disease activity, decreased work productivity, and worse quality of life. Further studies are needed to include rectal urgency assessment in routine clinical practice to better gauge disease activity in patients with UC or CD.

Mirikizumab Improves Quality of Life in Patients With Moderately-to-Severely Active Ulcerative Colitis: Results From the Phase 3 LUCENT-1 Induction and LUCENT-2 Maintenance Studies.

Background: Mirikizumab, 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. Methods: In 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). Results: At 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. Conclusions: Mirikizumab improved QoL in patients with moderately-to-severely active UC in phase 3 LUCENT-1 and LUCENT-2 studies. Clinical trials registration number: LUCENT-1: NCT03518086; LUCENT-2: NCT03524092.

Clinical profiles and outcomes in patients with ulcerative colitis receiving standard and higher-than-standard doses of vedolizumab: findings from a real-world study in Europe.

OBJECTIVE: Vedolizumab is an antibody targeting α4ß7 integrin used in the treatment of ulcerative colitis (UC). Patients are commonly prescribed higher-than-standard doses if treatment response is inadequate, but little is known about the drivers and impact of increased dosing. Our objective was to use real-world data to describe vedolizumab dosages in current clinical practice, patient characteristics, physicians' reasons for prescribing vedolizumab, and physician treatment satisfaction. METHODS: Data were derived from the Adelphi Real World UC vedolizumab Chart Review, a cross-sectional survey of gastroenterologists and their UC patients, conducted in France, Germany, Italy, Spain, and the United Kingdom between December 2022 and March 2023. Gastroenterologists provided data on patient demographics, clinical characteristics, treatment and vedolizumab dosage history, reasons for dose choice, and treatment satisfaction. RESULTS: Data were returned on 448 patients by 112 gastroenterologists. Overall, 83.5% of patients were on a standard vedolizumab dose and 10.3% were on a higher-than-standard dose. The worsening of symptoms was the most cited reason for higher doses. Most reported symptoms at survey were fatigue, abdominal distention or pain, diarrhea, and bowel urgency, with the latter particularly in higher-than-standard dose patients. Patients on higher-than-standard dose had high rates of mild (37.0%) or moderate (26.1%) disease, and low rates of remission (33.8%). Physicians were dissatisfied with treatment control for 2.7% of standard and 26.1% of higher-than-standard dose patients. CONCLUSIONS: Over 10% of patients were receiving a higher-than-standard dose of vedolizumab, but despite this were found to have suboptimal clinical outcomes and low physician satisfaction.

The Communicating Needs and Features of IBD Experiences (CONFIDE) Study: US and European Patient and Health Care Professional Perceptions of the Experience and Impact of Symptoms of Moderate-to-Severe Ulcerative Colitis.

BACKGROUND: The Communicating Needs and Features of IBD Experiences (CONFIDE) study aimed to evaluate the experience and impact of ulcerative colitis (UC) symptoms on patients' lives and elucidate gaps in communication between patients and health care professionals (HCPs). METHODS: Online, quantitative, cross-sectional surveys of patients with moderate-to-severe UC and HCPs responsible for making prescribing decisions were conducted in the United States (US) and Europe. UC disease severity was defined by treatment, steroid use, and/or hospitalization history. RESULTS: Surveys were completed by 200 US and 556 European patients and 200 US and 503 European HCPs. The most common UC symptoms experienced in the preceding month were diarrhea, bowel urgency, and increased stool frequency. Many patients (45.0% of US patients, 37.0% of European patients) reported wearing diapers/pads/protection at least once a week in the past 3 months due to fear/anticipation of fecal urge incontinence. The top reasons for declining participation in social events, work/school, and sports/exercise were due to bowel urgency and fear of fecal urge incontinence. HCPs ranked diarrhea, blood in stool, and increased stool frequency as the most common symptoms. While over half HCPs ranked bowel urgency as a top symptom affecting patients' lives, less than a quarter ranked it in the top 3 most impactful on treatment decisions. CONCLUSIONS: Similar disparities exist between patient and HCP perceptions in the United States and Europe on the experience and impact of UC symptoms. Bowel urgency has a substantial and similar impact on US and European patients, is underappreciated by HCPs, and should be addressed during routine appointments.

Clinical Effect of Mirikizumab Treatment on Bowel Urgency in Patients with Moderately to Severely Active Ulcerative Colitis and the Clinical Relevance of Bowel Urgency Improvement for Disease Remission.

Background: Bowel urgency reduces ulcerative colitis patients' quality of life. Mirikizumab, a p19-directed anti-IL-23 antibody, demonstrates ulcerative colitis efficacy. Mirikizumab efficacy to reduce bowel urgency and bowel urgency association with other endpoints were analyzed in 2 Phase 3 trials. Methods: LUCENT-1 (Induction): 1162 patients randomized 3:1 to intravenous 300 mg mirikizumab or placebo every 4 weeks for 12 weeks. LUCENT-2 (Maintenance): 544 mirikizumab responders during induction were re-randomized 2:1 to subcutaneous mirikizumab 200 mg or placebo every 4 weeks for 40 weeks (52 weeks of continuous treatment). Bowel urgency was measured using the Urgency Numeric Rating Scale (0-10); for patients with LUCENT-1 baseline score ≥3, bowel urgency clinically meaningful improvement (≥3-point decrease) and remission (score ≤1) rates in mirikizumab versus placebo groups were compared at Weeks 12 and 52. Associations between bowel urgency and other efficacy endpoints were assessed at Weeks 12 and 52. Results: A significantly higher proportion of mirikizumab patients versus placebo achieved clinically meaningful improvement in bowel urgency and remission at Weeks 12 and 52. Significantly higher percentages of patients achieving bowel urgency clinically meaningful improvement or remission, compared with those who did not, also achieved endpoints for clinical, corticosteroid-free, endoscopic, and symptomatic remission; clinical response; normalized fecal calprotectin and C-reactive protein; and improved quality of life. Conclusions: In patients with ulcerative colitis, bowel urgency improvement was associated with better clinical outcomes than in patients without improvement during induction and maintenance. A greater proportion of mirikizumab patients achieved sustainable bowel urgency improvement and remission compared to placebo patients.

P028 Communicating Needs and Features of IBD Experiences (CONFIDE) Survey: Patient and Healthcare Professional Perspectives on Experience of Ulcerative Colitis Symptoms.

BACKGROUND: Moderate-to-severe ulcerative colitis (UC) and Crohn's disease (CD) are associated with substantial quality of life and economic burdens (Kawalec, 2016). The Communicating Needs and Features of IBD Experiences (CONFIDE) study aims to further the understanding of the experience and impact of symptoms on patients' lives and elucidate any gaps in communication between healthcare professionals (HCPs) and patients with moderate-to-severe UC and CD in the United States (US), Europe, and Japan. These data focus on US patients with UC and US HCPs. METHODS: An online, quantitative, cross-sectional survey was conducted with HCPs (n=200) and patients with moderate-to-severe UC (n=200) in the US between May (HCPs) and July (patients) 2021. Moderate-to-severe UC was defined using criteria based on previous treatment experience, steroid use and/or hospitalization. The HCP survey included physicians (89%) and non-physician HCPs (11%) who are responsible for making prescribing decisions. Data collected included perspectives on the experience and impact of symptoms in patients with moderate-to-severe UC. RESULTS: The top three symptoms currently (past month) and ever suffered by patients (mean age: 40.4, 61.5% male) were diarrhea (62.5% and 74.0%, respectively), bowel urgency (47.0% and 61.5%) and increased stool frequency (38.5% and 57.5%). Blood in stool was reported by 27.0% of patients as currently suffering, and 51.0% ever. According to HCPs (78.0% male), the top three symptoms reported by patients were diarrhea (73.5% ranked in top 3), blood in stool (69.0%), and increased stool frequency (37.5%). Bowel urgency was recorded in the top 3 patient-reported symptoms by 24.0% of HCPs. Patients self-rated their disease-severity as 10.5% (n = 21) mild UC, 71.0% (n = 142) moderate UC, 17.5% (n = 35) severe UC, and 1.0% (n = 2) patients did not know. Bowel urgency was more frequently reported in patients with severe disease (62.9%, n = 22) when compared with those with mild-to-moderate disease (42.9%, n = 70). Among the overall patient population, 76.5% (n = 153) were receiving advanced therapies (biologic or novel oral therapy). Bowel urgency was currently experienced by 46.4% of these patients. Only 38.2% of patients felt completely comfortable reporting bowel urgency to their HCP. Of patients not comfortable reporting bowel urgency, 62.2% (n = 23) reported they felt embarrassed talking about it. Among HCPs, 75.5% (n = 151) reported they proactively discussed bowel urgency at routine appointments. Those HCPs who reported that they do not proactively discuss bowel urgency (24.5%, n = 49) cited the main reason as they expect the patient to bring it up (46.9%, n = 23). CONCLUSION: Bowel urgency is the second-most commonly reported symptom by patients with moderate-to-severe UC but is not among the HCP-perceived top three most reported symptoms. A substantial proportion of patients with moderate-to-severe UC receiving advanced therapies continue to report bowel urgency. A communication gap between patients and HCPs was identified and highlights the under appreciation of bowel urgency as an important symptom impacting patients' daily life.
