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.

Efficacy and Safety of Mirikizumab in a Randomized Phase 2 Study of Patients With Crohn's Disease.

BACKGROUND: Mirikizumab is a humanized monoclonal antibody targeting interleukin 23p19 with demonstrated efficacy in psoriasis and ulcerative colitis. We investigated the safety and efficacy of mirikizumab in patients with moderate-to-severe Crohn's disease (CD). METHODS: Patients (N = 191) were randomized (2:1:1:2) to receive placebo (PBO), 200, 600, or 1000 mg mirikizumab, administered intravenously (IV) every 4 weeks. Patients who received mirikizumab and achieved ≥1 point improvement in Simple Endoscopic Score-CD at Week 12 (rerandomized maintenance cohort) were rerandomized to continue their induction IV treatment (combined IV groups [IV-C]) or receive 300 mg mirikizumab subcutaneously (SC) every 4 weeks. Nonrandomized maintenance cohort included endoscopic nonimprovers (1000 mg) and PBO patients (PBO/1000 mg) who received 1000 mg mirikizumab IV from Week 12. The primary objective was to evaluate superiority of mirikizumab to PBO in inducing endoscopic response (50% reduction from baseline in Simple Endoscopic Score-CD) at Week 12. RESULTS: At Week 12, endoscopic response was significantly higher by the predefined 2-sided significance level of 0.1 for all mirikizumab groups compared with PBO (200 mg: 25.8%, 8/31, 95% confidence interval [CI], 10.4-41.2, P = .079; 600 mg: 37.5%, 12/32, 95% CI, 20.7-54.3, P = .003; 1000 mg: 43.8%, 28/64, 95% CI, 31.6-55.9, P < .001; PBO: 10.9 %, 7/64, 95% CI, 3.3-18.6). Endoscopic response at Week 52 was 58.5% (24/41) and 58.7% (27/46) in the IV-C and SC groups, respectively. Frequencies of adverse events (AE) in the mirikizumab groups were similar to PBO. Through Week 52, frequencies of treatment-emergent AEs were similar across all groups. Frequencies of serious AE and discontinuations due to AE were higher in the nonrandomized maintenance cohort. CONCLUSION: Mirikizumab effectively induced endoscopic response after 12 weeks in patients with moderate-to-severe CD and demonstrated durable efficacy to Week 52.

Identification of inadequate responders to advanced therapy among commercially-insured adult patients with Crohn's disease and ulcerative colitis in the United States.

BACKGROUND: The purpose of this analysis was to assess the frequency of inadequate response over 1 year from advanced therapy initiation among patients with Crohn's disease (CD) or ulcerative colitis (UC) in the United States using a claims-based algorithm. Factors associated with inadequate response were also analyzed. METHODS: This study utilized claims data of adult patients from the HealthCore Integrated Research Database (HIRD®) from January 01, 2016 to August 31, 2019. Advanced therapies used in this study were tumor necrosis factor inhibitors (TNFi) and non-TNFi biologics. Inadequate response to an advanced therapy was identified using a claims-based algorithm. The inadequate response criteria included adherence, switching to/added a new treatment, addition of a new conventional synthetic immunomodulator or conventional disease-modifying drugs, increase in dose/frequency of advanced therapy initiation, and use of a new pain medication, or surgery. Factors influencing inadequate responders were assessed using multivariable logistic regression. RESULTS: A total of 2437 patients with CD and 1692 patients with UC were included in this analysis. In patients with CD (mean age: 41 years; female: 53%), 81% had initiated TNFi, and 62% had inadequate response. In patients with UC (mean age: 42 years; female: 48%), 78% had initiated a TNFi, and 63% had an inadequate response. In both patients with CD and UC, inadequate response was associated with low adherence (CD: 41%; UC: 42%). Inadequate responders were more likely to be prescribed a TNFi (for CD: odds ratio [OR] = 1.94; p < 0.001; for UC: OR = 2.76; p < 0.0001). CONCLUSION: More than 60% of patients with CD or UC had an inadequate response to their index advanced therapy within 1 year after initiation, mostly driven by low adherence. This modified claims-based algorithm for CD and UC appears useful to classify inadequate responders in health plan claims data.

Efficacy and Safety of Continued Treatment With Mirikizumab in a Phase 2 Trial of Patients With Ulcerative Colitis.

BACKGROUND & AIMS: Mirikizumab is an antibody against the p19 subunit of interleukin 23 that has demonstrated clinical efficacy and was well tolerated following 12 weeks of induction treatment in a phase 2 trial of patients with moderate to severe ulcerative colitis. We present results of the open-label extended induction period in patients who did not initially respond to treatment with mirikizumab. METHODS: This study was a continuation of I6T-MC-AMAC, a double-blind trial, performed at 75 sites in 14 countries, in which patients with moderate to severe ulcerative colitis were randomly assigned to 12 weeks induction therapy with 50 mg, 200 mg, or 600 mg mirikizumab or placebo. Patients without a clinical response (a 9-point decrease in Mayo subscore of ≥2 points and ≥35% from baseline and either a decrease of rectal bleeding subscore of ≥1 or a rectal bleeding subscore of 0 or 1) at week 12 were offered the opportunity to participate in an open-label, extended induction study for another 12 weeks, in which they received either 600 mg intravenous mirikizumab (n = 20) or, following a protocol amendment, 1000 mg intravenous mirikizumab (n = 64) every 4 weeks. At week 24, patients with a clinical response continued the extension maintenance period and received 200 mg subcutaneous mirikizumab. Endpoints included clinical remission (Mayo subscores of 0 for rectal bleeding, 0 or 1 with a 1-point decrease from baseline), clinical response, endoscopic remission (Mayo endoscopic subscore of 0), or endoscopic improvement (endoscopic subscore of 0 or 1), at study weeks 24 and 52. Data were analysed for patients who received mirikizumab or placebo during the induction phase of the study. RESULTS: Among participants who did not respond to induction mirikizumab, 50.0% of those who received the 12-week extension of 600 mg mirikizumab and 43.8% who received the extension of 1000 mg mirikizumab achieved a clinical response; 15.0% and 9.4% achieved clinical remission, respectively. Endoscopic improvement was achieved by 20.0% of subjects in the 600 mg mirikizumab group and 15.6% subjects in the 1000 mg mirikizumab group. Among initial nonresponders to mirikizumab who had clinical response at study week 24 and continued into maintenance therapy, 65.8% maintained the clinical response, 26.3% achieved clinical remission, and 34.2% had endoscopic improvement at week 52. No new safety concerns were identified. CONCLUSIONS: Extended doses of mirikizumab (600 mg and 1000 mg) for an additional 12 weeks produce a clinical response in up to 50% of patients who did not have a clinical response to 12 weeks of induction doses (50 mg, 200 mg, or 600 mg). Most of the responders to the extended doses maintained clinical response for up to 52 weeks. Clinicaltrials.gov no: NCT02589665.

Medication use among patients with Crohn's disease or ulcerative colitis before and after the initiation of advanced therapy.

BACKGROUND: Although various treatments help reduce abdominal pain, real-world pain medication utilization among patients with Crohn's disease (CD) or ulcerative colitis (UC) receiving advanced therapies is poorly understood. The aim is to understand the utilization of pain medication 12 months before and after the initiation of advanced therapies among patients with newly diagnosed CD or UC. METHODS: This retrospective, observational cohort study used administrative medical and pharmacy claims data of patients with CD or UC from HealthCore Integrated Research Database (HIRD®). The data from patients with use of pain medication over 12 months follow-up (after the initiation date of advanced therapies) were collected and analyzed. Differences in the use of pain medication 12 months before and after the initiation of advanced therapies were assessed using McNemar's and Wilcoxon signed-rank test. RESULTS: Prior to initiating advanced therapies, 23.1% of patients with CD (N = 540) received nonsteroidal anti-inflammatory drugs (NSAIDs), 78.1% glucocorticoids, 49.4% opioids, and 29.3% neuromodulators; similarly, 20.9% of patients with UC (N = 373) received NSAIDs, 91.4% glucocorticoids, 40.8% opioids, and 29.5% neuromodulators. After receiving advanced therapies for 12 months, patients reported a reduction in the use of steroids (78.1% vs. 58.9%, P < 0.001 in CD; 91.4% vs. 74.3%, P < 0.001 in UC), opioids (49.4% vs. 41.5%, P = 0.004 in CD; 40.8% vs. 36.5%, P = 0.194 in UC), and NSAIDs (23.1% vs. 15.0%, P < 0.001 in CD; 20.9% vs. 15.8%, P = 0.035 in UC), while the use of neuromodulators significantly increased (29.3% vs. 33.7%, P = 0.007 in CD; 29.5% vs. 35.7%; P = 0.006 in UC). CONCLUSIONS: The use of pain medications such as NSAIDs, glucocorticoids, opioids, and neuromodulators was common among patients with CD or UC. These results highlight that patients with CD or UC continued to receive pain medications even after initiating advanced therapies.

Psychometric Properties of a Modified Version of the Faces Pain Scale-Revised (Modified FPS-R) to Evaluate Worst Pain in Children and Adolescents With Sickle Cell Anemia.

We evaluated psychometric properties (validity, reliability, and responsiveness) of a modified Faces Pain Scale-Revised (FPS-R) in 257 patients with sickle cell anemia (SCA) 7 to below 18 years old in a randomized, multinational clinical study. The modified FPS-R asks patients to report, by daily diary, their worst intraday SCA-related pain. Intraclass correlation coefficient assessed test-retest reliability between month 1 and month 2. Pearson correlations between monthly mean SCA-related pain intensity, activity interference score, analgesic use, and opioid use assessed convergent validity. Responsiveness was assessed with correlations of changes of monthly pain rate or intensity and changes in analgesic use or activity interference score from month 1 to month 9. Intraclass correlation coefficients for pain intensity and pain rate were 0.777 and 0.820, respectively, indicating agreement among stable patients. Moderate associations were shown between mean pain intensity and analgesic use (r=0.39) and opioid use (r=0.44), and between monthly pain rate and analgesic use (r=0.38). Moderate-to-large associations were observed between change in mean pain rate or intensity and changes in analgesic use (r=0.38 to 0.39, both P<0.001) and in activity interference scores (r=0.82 to 0.92, both P<0.001). These results support use of the modified FPS-R across cultures in children and adolescents aged 7 to below 18 years with SCA.

The Static Physician's Global Assessment of Genitalia: A Clinical Outcome Measure for the Severity of Genital Psoriasis.

Introduction: Genital psoriasis is a common but frequently overlooked manifestation of psoriasis with a considerable impact on patients' quality of life. Currently no validated clinical trial outcome measures exist to assess genital psoriasis severity that meet regulatory agency requirements. Methods: This study describes the development of the static Physician's Global Assessment of Genitalia (sPGA-G) scale, a clinical outcome measure for the assessment of genital psoriasis severity that accounts for the erythematous clinical presentation of genital psoriasis. The reliability of the sPGA-G was evaluated using scores collected from clinician assessments of photographs of genital psoriasis cases. Scores were collected from 10 academic and clinical experts in genital psoriasis and 95 clinician assessors who participated in either in-person (n=28) or online (n=67) sPGA-G training modules. Results: The sPGA-G had a high inter-rater reliability (IRR, measured by Kendall's W) for expert raters (W=0.856, P less than 0.0001), in-person assessors (W=0.822, P less than 0.0001), and online assessors (W=0.678, P less than 0.0001). IRR was also high for all clinical assessors combined, (W=0.714, P less than 0.0001). Discussion: This study demonstrates that the sPGA-G is an intuitive and reliable clinical outcome measure that specifically measures the severity of genital psoriasis.

Interpreting change from patient reported outcome (PRO) endpoints: patient global ratings of concept versus patient global ratings of change, a case study among osteoporosis patients.

BACKGROUND: Regulatory guidance recommends anchor-based methods for interpretation of treatment effects measured by PRO endpoints. Methodological pros and cons of patient global ratings of change vs. patient global ratings of concept have been discussed but empirical evidence in support of either approach is lacking. This study evaluated the performance of patient global ratings of change and patient global ratings of concept for interpreting patient stability and patient improvement. METHODS: Patient global ratings of change and patient global ratings of concept were included in a psychometric validation study of an osteoporosis-targeted PRO instrument (the OPAQ-PF) to assess its ability to detect change and to derive responder definitions. 144 female osteoporosis patients with (n = 37) or without (n = 107) a recent (within 6 weeks) fragility fracture completed the OPAQ-PF and global items at baseline, 2 weeks (no recent fracture), and 12 weeks (recent fracture) post-baseline. RESULTS: Results differed between the two methods. Recent fracture patients reported more improvement while patients without recent fracture reported more stability on ratings of change than ratings of concept. However, correlations with OPAQ-PF score change were stronger for ratings of concept than ratings of change (both groups). Effect sizes for OPAQ-PF score change increased consistently with level of change in ratings of concept but inconsistently with ratings of change, with the mean AUC for prediction of a one-point change being 0.72 vs. 0.56. CONCLUSIONS: This study provides initial empirical support for methodological and regulatory recommendations to use patient global ratings of concept rather than ratings of change when interpreting change captured by PRO instruments in studies evaluating treatment effects. These findings warrant being confirmed in a purpose-designed larger scale analysis.

Psychometric properties of the osteoporosis assessment questionnaire (OPAQ) 2.0: results from the multiple outcomes of raloxifene evaluation (MORE) study.

BACKGROUND: We explored psychometric properties of the Osteoporosis Assessment Questionnaire 2.0 in terms of reliability, validity, and responsiveness with generic, clinical, demographic, and preference-based data collected from a population of postmenopausal women with osteoporosis. METHODS: The Multiple Outcomes of Raloxifene Evaluation study was a randomized, placebo-controlled, multinational clinical trial evaluating efficacy and safety of raloxifene. The Osteoporosis Assessment Questionnaire 2.0, a generic quality of life measure (Nottingham Health Profile), and a preference-based measure (Health Utilities Index) were administered at baseline and annually. Psychometric properties of the 14 Osteoporosis Assessment Questionnaire 2.0 domains were evaluated by standard statistical techniques. RESULTS: This study included a subset of 1477 women from the Multiple Outcomes of Raloxifene Evaluation study population completing the questionnaires. Mean (standard deviation) age was 68.4 (6.8) years. Prevalent vertebral fractures were found in 70% (n =1038) of women. Internal consistency was >0.7 in 9 Osteoporosis Assessment Questionnaire 2.0 domains. Correlations were moderate and significant for similar Osteoporosis Assessment Questionnaire 2.0 domain scores, Nottingham Health Profile domains, and Health Utilities Index scores. All but 2 Osteoporosis Assessment Questionnaire 2.0 domains distinguished between patients with or without prevalent vertebral fractures and detected worsening with increased number of vertebral fractures. Women with ≥ 1 incident vertebral fracture generally had a greater worsening in Osteoporosis Assessment Questionnaire 2.0 scores (excluding social activity and support of family and friends) from baseline to study endpoint compared with women without incident vertebral fractures. CONCLUSIONS: Most domains in the Osteoporosis Assessment Questionnaire 2.0 demonstrated robust psychometric properties; however, several domains not showing these criteria may need to be reassessed and removed for a potentially shorter and validated version of the Osteoporosis Assessment Questionnaire.

Association of fatigue with disease activity and clinical manifestations in patients with Crohn's disease and ulcerative colitis: an observational cross-sectional study in the United States.

BACKGROUND: Fatigue imposes a socioeconomic burden on patients with Crohn's disease (CD) and ulcerative colitis (UC). We assessed the prevalence of fatigue among patients with CD or UC and identified disease activity measures associated with fatigue. METHODS: Data from the Study of a Prospective Adult Research Cohort with Inflammatory Bowel Disease (SPARC IBD) were analyzed separately for CD and UC. Fatigue was defined based on a subjective and dichotomic questionnaire. Patients indicated if they experienced fatigue within the last week. The overall prevalence of fatigue was analyzed using descriptive and contingency tables. Demographics, clinical characteristics, disease activity (measures include Physician's Global Assessment for both CD and UC, short CD Activity Index for CD, and Ulcerative Colitis Disease Activity Index for UC), symptoms, and patient-reported outcomes were compared between patients with and without fatigue. Multivariable logistic regression models were constructed to identify symptoms and disease activity measures associated with fatigue. RESULTS: The study included 903 patients with CD and 443 patients with UC. Fatigue was reported in 47.7% of patients with CD and 40.9% of patients with UC. In patients with CD, abdominal pain, bowel incontinence, depressive symptoms, reduced general well-being, and night-time bowel movements were associated with fatigue. In patients with UC, depressive symptoms, reduced general well-being, moderate or severe disease activity by the physician's global assessment, and night-time bowel movements were significantly associated with fatigue. CONCLUSIONS: Fatigue is a common symptom among patients with CD or UC and is associated with higher levels of disease activity and reduced general well-being.

Inflammatory bowel disease (IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC), can lead to fatigue in many patients regardless of their disease severity. Fatigue not only affects patients' quality-of-life but also their ability to work and their mental health. However, research specific to the IBD related symptoms that contribute to fatigue in these patients is not currently available, especially in the United States (US). To address this gap, real-world data was analyzed to understand how common fatigue is among patients with CD and UC in the US and clinical symptoms that co-occur with fatigue. We found that fatigue affects more than 40% of the patients. Our results suggest that fatigue is correlated with more severe disease symptoms and overall lower well-being among patients with CD and UC.

The Clinical Course of Bowel Urgency Severity Among Patients with Inflammatory Bowel Disease-A Real-World Study.

BACKGROUND: Bowel urgency is a highly burdensome symptom among patients with inflammatory bowel disease (IBD). OBJECTIVES: To assess changes in severity of bowel urgency and identify predictors of worsening or improvement among patients with Crohn's disease (CD) and ulcerative colitis (UC) at 6 months from their enrollment visit. METHODS: Data from patients in the Study of a Prospective Adult Research Cohort with IBD were analyzed. Enrolled patients with CD or UC with 6-month visits were included. Changes and predictors of bowel urgency severity over 6 months in patients with CD or UC were examined using two separate analyses: (a) "worsening" versus "no change" excluding those with moderate-to-severe bowel urgency at enrollment, and (b) "improvement" versus "no change" excluding those with no bowel urgency at enrollment. The enrollment characteristics were compared within these groups. RESULTS: At baseline, in both CD and UC, use of biologics and/or immunomodulators at enrollment was similar across cohorts. Among patients with CD, 206 of 582 (35.4%) reported worsening, and 195 of 457 (42.7%) reported improvement in bowel urgency. Younger age (P = 0.013) and moderate-to-severe bowel urgency (P < 0.001) were associated with improvement. Moderate bowel urgency (P = 0.026) and bowel incontinence while awake (P = 0.022) were associated with worsening. Among patients with UC, 84 of 294 (28.6%) reported worsening, and 111 of 219 (50.7%) reported improvement in bowel urgency. Higher symptomatic disease severity (P = 0.011) and more severe bowel urgency (P < 0.001) were associated with improvement. CONCLUSIONS: Bowel urgency is an unpredictable and unstable symptom among patients with IBD. Over 50% of patients with CD or UC experienced either worsening or improvement at 6 months postenrollment.

WHAT IS KNOWN ABOUT BOWEL URGENCY IN INFLAMMATORY BOWEL DISEASE (IBD)?: Around six to eight in every ten patients with inflammatory bowel disease suffer from bowel urgency, a sudden need to have bowel movement. Many patients with IBD perceive bowel urgency as a bothersome symptom impacting their everyday activities. WHY DID WE DO THIS STUDY?: Despite the importance of bowel urgency, the changes in bowel urgency severity among the IBD-affected US population are yet to be fully known. We aimed to assess changes in severity of bowel urgency in patients with Crohn's disease (CD) or ulcerative colitis (UC) at 6 months. WHAT HAVE WE FOUND FROM THIS STUDY?: Bowel urgency is a common and unpredictable symptom among patients with CD and UC. Over 50% of patients reported that the severity of bowel urgency has either worsened or improved at the 6 months postenrollment. While about 40­50% of IBD patients reported improvement, about 30% reported worsening, suggesting a lack of effective therapies to treat bowel urgency. FUTURE IMPLICATION: There is a need for advanced therapies to resolve bowel urgency in patients with CD and UC.

Distinguishing community-associated from hospital-associated Clostridium difficile infections in children: implications for public health surveillance.

BACKGROUND: Children are increasingly recognized as being at risk for C. difficile infection (CDI), even without prior exposure to antibiotics or the healthcare environment. We aimed to distinguish risk factors, clinical course, and outcomes between healthcare facility-associated (HA) and community-associated (CA) CDI. METHODS: This was a retrospective, observational cohort study conducted at the Johns Hopkins Children's Center, Baltimore, Maryland. All inpatients, aged ≥1 year, hospitalized from July 2003 to July 2012 and diagnosed with CDI based on clinical characteristics and confirmatory laboratory testing were included. The main outcome was CDI, categorized as HA-CDI, CA-CDI, and "indeterminate" (classified as disease onset in the community, 4-12 weeks from hospital discharge). RESULTS: Two hundred two pediatric inpatients were diagnosed with CDI, of whom 38 had CA-CDI, 144 had HA-CDI, and 20 had indeterminate CDI. Children with indeterminate CDI had baseline characteristics similar to those identified for HA-CDI. Children hospitalized with CA-CDI were less likely to have comorbidities (odds ratio [OR], 0.14; 95% confidence interval [CI], .03-.65; P = .013), to have been exposed to antibiotics (OR, 0.17; 95% CI, .07-.44; P < .001), or prior surgeries (OR, 0.03; 95% CI, .00-.24; P = .001), compared to children with HA-CDI. Compared with HA-CDI, children with CA-CDI had a trend toward more episodes of septic shock (P = .07), toxic megacolon (P = .04), and recurrences (P = .04). CONCLUSIONS: In a hospitalized cohort, CA-CDI is more often seen in previously healthy children without antibiotic exposure or comorbid conditions and has more frequent complications and recurrences compared to HA-CDI. For surveillance purposes, "indeterminate" CDI should be allocated to HA-CDI rather than CA-CDI.

The patient experience with fatigue and content validity of a measure to assess fatigue severity: qualitative research in patients with ankylosing spondylitis (AS).

BACKGROUND: Ankylosing spondylitis (AS) is an autoimmune disorder characterized by inflammation of the spine and large joints. Fatigue is a common symptom that many AS patients find significantly impacts their health-related quality of life. The Worst Fatigue - Numeric Rating Scale (WF-NRS) assesses the severity of this symptom during the previous 24-hour period. The objective of this study was to perform qualitative research to support the development and content validity of the WF-NRS. METHODS: Patients with AS were recruited from clinical sites in the U.S. for a qualitative study which first entailed concept elicitation interviews to gain understanding of the patients' experience with AS and fatigue. Subsequently, cognitive debriefing interviews were undertaken to assess the understandability, clarity, and appropriateness from the patient's perspective, of the content of a measure of fatigue severity. RESULTS: Thirteen patients with AS participated in concept elicitation interviews and cognitive debriefing of the Brief Fatigue Inventory (BFI) fatigue severity subscale. The WF-NRS was developed from the worst fatigue item of the BFI as patients generally reported it to be understandable and covered an important concept, the completion instructions were modified, but the response scale remained as it was familiar and readily completed, and the recall period was appropriate. CONCLUSIONS: Patient responses resulted in the development of and supported the content validity of the WF-NRS. Further quantitative evaluation of the WF-NRS is warranted in order to assess its psychometric properties and confirm its usefulness as a clinical trial tool.

Use of health-related quality of life measures to predict health utility in postmenopausal osteoporotic women: results from the Multiple Outcomes of Raloxifene Evaluation study.

BACKGROUND: The aim of this study is to examine the associations between health utility (HU), health-related quality of life (HRQoL), and patient characteristics in postmenopausal osteoporotic (PMO) women. METHODS: Baseline data from a subsample of 1,245 participants of the Multiple Outcomes of Raloxifene Evaluation study, a randomized, placebo-controlled, multinational clinical trial to evaluate the safety and efficacy of raloxifene, were analyzed. The study cohort included 694 participants from non-European Union (non-EU) countries and 551 participants from EU countries. All participants with complete baseline HU and HRQoL assessments were included in the following analyses: 1) HU (HUI or EQ-5D) and HRQoL (QualEFFO or OPAQ and NHP) associations; 2) HU variability explained by HRQoL domains; and 3) the percentage of HU variability explained by statistically significant (p < 0.05) HRQoL domains, after adjusting for baseline characteristics. RESULTS: Several domains were significantly associated with HU scores. HU variance was well explained (41% to 61%) by 4 to 6 (p < 0.05) significant HRQoL domains. After controlling for baseline characteristics, 48% to 64% of the HU variance was well explained by 5 to 7 significant (p < 0.05) HRQoL domains. Additional trend analyses detected statistically significant decreases in HRQoL and HU scores with an increased number of vertebral and non-vertebral fractures. CONCLUSIONS: Both disease-targeted and generic HRQoL domains were well correlated with HU. A large percentage (48% to 64%) of the HU variance was explained by HRQoL, after adjusting for baseline characteristics. Both disease-targeted and generic HRQoL measures were significant predictors of HU. HRQoL and HU scores decreased with increased vertebral and non-vertebral fractures.

Identifying Measures of Suboptimal Healthcare Interaction (SOHI) to Develop a Claims-Based Model for Predicting Patients with Inflammatory Bowel Disease at Risk for SOHI.

BACKGROUND: Understanding the demographic and clinical characteristics of patients with Inflammatory Bowel Disease (IBD) who are likely to experience poor disease outcomes may allow early interventions that can improve health outcomes. OBJECTIVES: To describe demographic and clinical characteristics of patients with ulcerative colitis (UC) and Crohn's disease (CD) with the presence of at least one Suboptimal Healthcare Interaction (SOHI) event, which can inform the development of a model to predict SOHI in members with IBD based on insurance claims, with the goal of offering these patients some additional intervention. METHODS: We identified commercially insured individuals with IBD between 01 January 2019 and 31 December 2019 using Optum Labs' administrative claims database. The primary cohort was stratified on the presence or absence of ≥ 1 SOHI event (a SOHI-defining data point or characteristic at a specific time point) during the baseline observation period. SOHI was deployed as the basis for the development of a model to predict which individuals with IBD were most likely to continue to have SOHI within a 1-year timeframe (follow-up SOHI) using insurance claims data. All baseline characteristics were analyzed descriptively. Multivariable logistic regression was used to examine the association of follow-up SOHI with baseline characteristics. RESULTS: Of 19,824 individuals, 6872 (34.7%) were found to have follow-up SOHI. Individuals with follow-up SOHI were more likely to have had similar SOHI events in the baseline period than those with non-SOHI. A significantly greater proportion of individuals with SOHI had ≥ 1 claims-based C-reactive protein (CRP) test order and ≥ 1 CRP lab results compared with non-SOHI. Individuals with follow-up SOHI were more likely to incur higher healthcare expenditures and resource utilization as compared with non-SOHI individuals. A few of the most important variables used to predict follow-up SOHI included baseline mesalamine use, count of baseline opioid fills, count of baseline oral corticosteroid fills, baseline extraintestinal manifestations of disease, proxy for baseline SOHI, and index IBD provider specialty. CONCLUSION: Individuals with SOHI are likely to have higher expenditures, higher healthcare resource utilization, uncontrolled disease, and higher CRP lab results as compared with non-SOHI members. Distinguishing SOHI and non-SOHI patients in a dataset could efficiently identify potential cases of poor future IBD outcomes.

We have developed a model for identifying suboptimal healthcare interactions (SOHI) at follow-up and used it to predict the individuals with inflammatory bowel disease (IBD) who are likely to suffer poor healthcare outcomes. Our study showed that the SOHI and non-SOHI cohorts had notable differences in clinical baseline characteristics. Compared with non-SOHI members, individuals with SOHI experienced poor IBD outcomes and incurred higher healthcare resource utilization and costs. Understanding baseline characteristics of patients with SOHI to predict follow-up SOHI can improve health outcomes by early identification of patients with IBD who are likely to experience it. This can help in targeting efforts toward additional care, resulting in greater chances of a well-managed disease.

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.

Burden of Fatigue Among Patients with Ulcerative Colitis and Crohn's Disease: Results from a Global Survey of Patients and Gastroenterologists.

INTRODUCTION: To assess the prevalence of fatigue and its association with disease activity and patient-reported outcomes among patients with ulcerative colitis (UC) or Crohn's disease (CD). METHODS: Data from a cross-sectional survey conducted with gastroenterologists and their consulting adult patients with UC or CD were analyzed. Data were collected via gastroenterologist-completed patient record forms and patient-self completion forms. Patient demographics, clinical characteristics, disease activity and medication use were reported by the gastroenterologist, while current symptoms (fatigue, rectal urgency, abdominal pain, sleep disturbance), work productivity and the Short Inflammatory Bowel Disease Questionnaire (SIBDQ) were reported by the patient. Logistic regression models were used to identify measures associated with fatigue and expressed as odds ratio (OR) with 95% confidence interval. p < 0.05 was considered statistically significant. RESULTS: A total of 1057 patients with UC and 1228 patients with CD were included in this analysis. Fatigue was reported in 22.6% of UC and 26.0% of patients with CD. Higher proportion of patients with UC and fatigue had moderate/severe disease activity (p = 0.0001), had a higher Mayo score (5.0 vs. 4.0, p < 0.0001) and were unemployed (5.6% vs. 3.9%, p = 0.0149) compared to those without fatigue. In patients with CD reporting fatigue, a higher proportion were female (55.9% vs. 48.2%, p = 0.0193), were unemployed (5.8% vs. 4.9%, p = 0.0069), had moderate/severe disease (p < 0.0001) and had a higher mean Crohn's Disease Activity Index score (145.0 vs. 96.2, p < 0.0001) than patients without fatigue. Patients with UC and fatigue had higher mean level of pain (p < 0.0001) and sleep disturbance (p < 0.0001), whereas patients with CD and fatigue had lower SIBDQ scores (p < 0.0001) and greater work impairment (p = 0.0015) than patients without fatigue. Abdominal pain (OR: 2.01, p = 0.001) and use of immunomodulators (OR: 1.69, p = 0.006) increased the odds of having fatigue in patients with UC. In patients with CD, abdominal pain (OR: 2.29, p < 0.001) and use of biologics or biosimilars (OR: 2.02, p = 0.003) increased the odds of having fatigue. CONCLUSION: Fatigue is a common symptom among patients with UC or CD that is associated with higher levels of disease activity and decreased work productivity and is driven by various factors. A multidisciplinary approach may be needed to manage fatigue.

Qualitative interviews to evaluate content validity of the ACTIV-2 COVID-19 Symptom Diary (ACSD).

BACKGROUND: Patient-reported outcome measures are needed to assess the impact of treatments for COVID-19 on symptoms. The ACTIV-2 COVID-19 Symptom Diary (ACSD) is being used in the ongoing Accelerating COVID-19 Therapeutic Interventions and Vaccines-2 (ACTIV-2) platform clinical trial. The purpose of the current study was to conduct qualitative interviews to assess content validity of the ACSD. METHODS: Interviews were conducted with adults who had tested positive for SARS-CoV-2. The ACSD begins with global items, followed by a symptom checklist. Each interview began with concept elicitation focusing on participant experiences with COVID-19. Then, participants completed the ACSD, and cognitive interviews were conducted to evaluate the questionnaire. Interviews were recorded, transcribed, and coded following a qualitative content analysis. For the qualitative analysis, a coding dictionary was developed with a list of all potential codes and instructions for how the codes should be applied and combined. RESULTS: Interviews were conducted with 30 participants (mean age = 39 years; 57% female; 17% Latinx; 17% Black/African American; 40% meeting at least one criterion for classification as high risk of progression to severe COVID-19). Commonly reported symptoms included fatigue (reported by 100% of the sample), body pain/muscle pain/aches (87%), headaches (87%), cough (83%), loss of smell (73%), shortness of breath/difficulty breathing (70%), and chills (70%). The 13 symptoms most commonly reported in this study are included in the ACSD. After completing the ACSD, participants consistently reported that it was clear and easy to complete, and all items were generally interpreted as intended. Based on participants' input, the ACSD was edited slightly after the first 13 interviews, and the revised version was used for the final 17 interviews. Two additional items assessing "brain fog" and dizziness were recommended for addition to the ACSD in future research. CONCLUSIONS: This qualitative study supports the content validity of the ACSD for assessment of COVID-19 symptoms. Quantitative research with larger samples will be needed to examine the questionnaire's measurement properties.

This study focused on the ACTIV-2 COVID-19 Symptom Diary (ACSD), a questionnaire that assesses symptom severity of COVID-19. The ACSD begins with global items assessing overall symptom severity, followed by a symptom checklist focusing on individual symptoms. Interviews were conducted with 30 adults who had tested positive for COVID-19. The patients reported their experiences with COVID-19, completed the ACSD, and provided their opinions about the ACSD. Based on input from these patients, the ACSD appears to be clear and easy to complete, and it includes the most common and important symptoms of COVID-19. The ACSD was edited for clarity, and "brain fog" and dizziness were recommended additions for future research. This study suggests that the ACSD is a useful questionnaire for assessment of COVID-19 symptoms in clinical studies. Studies like this are important for ensuring that symptoms are measured appropriately and accurately in clinical trials. Future research with larger samples will be needed to further examine the questionnaire.

Changes in health-related quality of life and associations with improvements in clinical efficacy: a Phase 2 study of mirikizumab in patients with ulcerative colitis.

OBJECTIVE: Mirikizumab, a monoclonal antibody targeting the interleukin-23 p19 subunit, was effective in a Phase 2 study (NCT02589665) of moderately-to-severely active ulcerative colitis (UC). We studied mirikizumab's impact on health-related quality of life (HRQoL). DESIGN: HRQoL was evaluated using the Inflammatory Bowel Disease Questionnaire (IBDQ) and 36-Item Short Form Health Survey (SF-36) Physical Component Score (PCS) and Mental Component Score (MCS). Mixed effects models for repeated measures compared score changes between mirikizumab and placebo groups. Additional analyses evaluated associations between HRQoL score changes and achievement of efficacy endpoints at weeks 12 and 52. RESULTS: At week 12, IBDQ improved compared with placebo for all mirikizumab groups except mirikizumab 50 mg (50 mg, p=0.073; 200 mg, p<0.001; 600 mg, p<0.001). SF-36 PCS was significantly higher in all mirikizumab groups at week 12 (50 mg, p=0.011; 200 mg, p=0.022; 600 mg, p=0.002); MCS was significantly higher in mirikizumab 200 and 600 mg groups compared with placebo (50 mg, p=0.429; 200 mg, p=0.028; 600 mg, p<0.001). Achievement of clinical response and remission were associated with greater HRQoL improvements at week 12. Improvements in HRQoL scores were sustained through week 52. Of the clinical symptoms evaluated, reduction in rectal bleeding was associated with greater improvements in IBDQ and SF-36 scores. CONCLUSION: Mirikizumab improved HRQoL in patients with moderately-to-severely active UC.

Change in Urgency Status Among Ulcerative Colitis Patients: Understanding a Potential Unmet Patient Need From the CorEvitas Inflammatory Bowel Disease Registry.

Background and Aims: Fecal urgency is a common symptom of Ulcerative Colitis (UC). We explored the association between changes in fecal urgency for patient characteristics and evaluated the association between change in treatment and change in fecal urgency. Methods: The study cohort (n = 400) included UC patients in the CorEvitas Inflammatory Bowel Disease Registry between May 3, 2017 and September 1, 2020. Fecal urgency was defined using the Simple Clinical Colitis Activity Index. Urgency groups were formed by urgency at enrollment and 6-month follow-up visit: no persistent urgency at both visits (NPU); change from urgency to no urgency (UN); change from no urgency to urgency (NU); and persistent urgency at both visits (PU). Descriptive statistics were used to explore between urgency group differences at baseline and Kaplan-Meier curves to compare time to first treatment change. Results: Groups included NPU (n = 175), UN (n = 86), NU (n = 56), and PU (n = 83). At enrollment, we found differences between groups for increased depression, anxiety, prior infections, diabetes; also, greater fatigue, pain, work impairment, work hours affected, and daily activities impacted. Compared to NPU patients, UN, NU, and PU patients were more likely to change treatment between enrollment and 6-month follow-up visit, and a higher proportion of UN, NU, and PU patients on a biologic at enrollment changed treatment vs the NPU group between both visits. Conclusion: Among real-world UC patients, fecal urgency status is associated with increased comorbidities and worse patient-reported outcomes and significant differences in change of treatment and time to treatment change. Urgency at any time point diminishes quality of life and may be a sign of inadequate therapy, which often is an indication to switch therapy.
