Patient views about the impact of ulcerative colitis and its management with drug treatment and surgery: a nested qualitative study within the CONSTRUCT trial

Patient experiences in ulcerative colitis: conceptual model and review of patient-reported outcome measures

PURPOSE

To identify symptoms and their impacts on daily functioning and health-related quality of life (HRQoL) experienced by adult patients with ulcerative colitis (UC) and evaluate patient-reported outcome (PRO) measures for UC clinical studies.

METHODS

A conceptual model of symptoms and impacts of UC were developed from a literature review. PRO measures were identified from the literature, clinical trials databases, health technology assessment submissions, and regulatory label claims, and were selected for conceptual analysis based on disease specificity and use across information sources. PRO measures covering the most concepts when mapped against the conceptual model were assessed for gaps in psychometric properties using Food and Drug Administration (FDA) guidance and consensus-based standards for the selection of health measurement instruments (COSMIN) criteria.

RESULTS

The conceptual model grouped the 52 symptom concepts and 72 proximal and distal impacts into eight, two, and five dimensions, respectively. Of 65 PRO measures identified, eight underwent conceptual analysis. Measures covering the most concepts and assessed for psychometric properties were the Inflammatory Bowel Disease Questionnaire, Symptoms and Impacts Questionnaire for UC, UC-PRO symptoms modules, UC-PRO impact modules, and Crohn's and UC Questionnaire; all had good or excellent support for content validity. The UC-PRO Signs and Symptoms fully met FDA guidance and COSMIN criteria for content validity and most psychometric properties.

CONCLUSION

Existing PRO measures assess concepts relevant to patients with UC, but all PRO measures reviewed require further psychometric evaluation to demonstrate they are fit for purpose.

Upadacitinib Induction and Maintenance Therapy Improves Abdominal Pain, Bowel Urgency, and Fatigue in Patients With Ulcerative Colitis: A Post Hoc Analysis of Phase 3 Data

BACKGROUND

This post hoc analysis of a large, phase 3 program evaluated the effects of upadacitinib on fatigue, bowel urgency, and abdominal pain in patients with moderately to severely active ulcerative colitis.

METHODS

Induction data were pooled from 2 identical studies, the U-ACHIEVE induction and U-ACCOMPLISH studies. Patients in these studies received upadacitinib 45 mg once daily or placebo as induction treatment. Responders to induction treatment were rerandomized in the U-ACHIEVE maintenance study to upadacitinib 15 mg once daily, upadacitinib 30 mg, or placebo. The percentage of patients reporting no abdominal pain and no bowel urgency daily via an electronic diary and a meaningful within-person change (≥5 points) in the Functional Assessment of Chronic Illness Therapy-Fatigue score were evaluated.

RESULTS

The results demonstrated a statistically significantly greater percentage of patients reporting no abdominal pain and absence of bowel urgency observed from week 2 (P < .001), with upadacitinib induction treatment and clinically meaningful improvements in Functional Assessment of Chronic Illness Therapy-Fatigue score observed at week 8 (P < .001), when compared with placebo. The maintenance study showed that significant and meaningful improvements in abdominal pain, bowel urgency, and Functional Assessment of Chronic Illness Therapy-Fatigue score achieved during induction were sustained through 52 weeks of maintenance treatment in upadacitinib- vs placebo-treated patients.

CONCLUSIONS

The findings of this study support the additional benefit of upadacitinib in treating moderately to severely active ulcerative colitis by demonstrating a statistically significant impact on clinically meaningful symptoms of fatigue, bowel urgency, and abdominal pain.(U-ACHIEVE induction and maintenance studies; NCT02819635; U-ACCOMPLISH induction study; NCT03653026).

Integrating qualitative interviews in drug development and the use of qualitative evidence in product labelling and health technology assessments: a review

Objective

Including qualitative research in clinical trial design is an innovative approach to understanding patients' perspective and incorporate the patient's voice in all stages of drug development and evaluation. This review aims to explore current practices, lessons learned from the literature, as well as how qualitative interviews are considered by health authorities for marketing authorization and reimbursement.

Methods

A targeted literature review of Medline and Embase databases was conducted in February 2022 to identify publications on qualitative methods embedded in clinical trial of pharmaceutical products. An additional search of guidelines and labeling claims of approved products regarding qualitative research was performed in various sources of grey literature.

Results

From the 24 publications and nine documents reviewed, we identified the research questions addressed with qualitative methods during clinical trials (e.g., change in quality of life, symptoms assessment, treatment benefit), preferred data collection methods (e.g., interviews), and data collection points (e.g., baseline and exit interviews). Moreover, the data from labels and HTAs demonstrate that qualitative data can play an important role in approval processes.

Conclusion

The use of in-trial interviews is still emerging and is not yet common practice. Although the industry, scientific community, regulatory agencies and HTAs are showing an increasing interest in the use of evidence generated via in-trial interviews, guidance from regulators and HTAs would be helpful. Developing new methods and technologies to address the common challenges for such interviews is key to progress.

Medical consultation in ulcerative colitis: Key elements for improvement

Ulcerative colitis (UC) is a chronic inflammatory disease with a high impact. In order to improve patient outcomes, the clinician-patient relationship in daily practice is critical. Clinical guidelines provide a framework for UC diagnosis and treatment. However, standard procedures and the medical content focused upon medical consultations in UC patients has not yet been defined. Moreover, UC is a complex disease, given that patient characteristics and patient needs have been proven to vary during clinical consultation since establishing the diagnosis and upon the course of the disease. In this article, we have discussed the key elements and specific objectives to consider in medical consultation, such as diagnosis, first visits, follow-up visits, active disease patients, patients on topical therapies, new treatment initiation, refractory patients, extra-intestinal manifestations, as well as challenging situations. The key elements have been mentioned to comprise effective communication techniques, motivational interviewing (MI), as well as information and educational aspects, or organizational issues. The key elements to be implemented in daily practice were reported to comprise several general principles like duly prepared consultations, in addition to honesty and empathy with patients, as well as effective communication techniques, MI, information and educational points, or organizational issues. The role of other healthcare professionals such as specialized nurses, psychologists, or the use of checklists was also discussed and commented on.

Safety and tolerability of spesolimab in patients with ulcerative colitis

BACKGROUND

Interleukin (IL)-36 signaling has been shown to be increased in ulcerative colitis (UC). Spesolimab, a novel humanized monoclonal antibody, targets the IL-36 pathway.

RESEARCH DESIGN AND METHODS

We report safety, immunogenicity, and efficacy data of intravenous (IV) spesolimab in UC. Study 1: phase II, randomized, placebo-controlled trial (300 mg single dose; 450 mg every 4 weeks [q4w]; or 1,200 mg q4w, three doses). Study 2: phase IIa, randomized, placebo-controlled trial (1,200 mg q4w). Study 3: phase IIa, open-label, single-arm trial (1,200 mg q4w). Studies lasted 12 weeks, with a 12-, 24-, and 16-week safety follow-up, respectively.

RESULTS

Adver+se event (AE) rates were similar for spesolimab and placebo in Studies 1 (N = 98; 64.9%; 65.2%) and 2 (N = 22; 86.7%; 71.4%); all patients in Study 3 (N = 8) experienced AEs. The most frequent investigator-assessed drug-related (spesolimab; placebo) AEs were skin rash (5.4%; 0%) and nasopharyngitis (4.1%; 0%) in Study 1; acne (13.3%; 0%) in Study 2; one patient reported skin rash, nasopharyngitis, headache, and acne in Study 3. Efficacy endpoints were not met.

CONCLUSIONS

Spesolimab was generally well tolerated, with no unexpected safety concerns. The safety data are consistent with studies in other inflammatory diseases.

Quality of Life in Patients with Acute Severe Ulcerative Colitis: Long-Term Follow-Up Results from the CONSTRUCT Trial

BACKGROUND

there is currently limited research examining the QoL of patients with Ulcerative colitis (UC) following treatment of acute severe colitis (ASUC).

OBJECTIVE

to examine the long-term QoL of ASUC patients enrolled in the CONSTRUCT trial following treatment of UC with infliximab or ciclosporin and to compare the differences in the QoL between the two drug treatments over time.

METHODS

The CONSTRUCT trial examined the cost and clinical effectiveness of infliximab and ciclosporin treatments for acute severe UC. We collected QoL questionnaire data from patients during the active trial period up to 36 months. Following trial completion, we contacted patients postannually for up to a maximum of 84 months. We collected QoL data using a disease-specific (CUCQ, or CUCQ+ for patients who had colectomy surgery) or generic (EQ5D-3L) questionnaire. We analysed QoL scores to determine if there was any difference over time and between treatments in generic or disease-specific QoL.

RESULTS

Following initial treatment with infliximab and ciclosporin, patients experienced a statistically significant improvement in both the generic and disease-specific QoL at three months. Generic scores remained fairly static for the whole follow-up period, reducing only slightly up to 84 months. Disease-specific scores showed a much sharper improvement up to 2 years with a gradual reduction in QoL up to 84 months. Generic and disease-specific QoL remained higher than baseline values. There was no significant difference between treatments in any of the QoL scores.

CONCLUSIONS

Both infliximab and ciclosporin improve QoL following initial treatment for ASUC. QoL scores remain higher than at admission up to 84 months post-treatment.

Patient preferences and current practice for adults with steroid-resistant ulcerative colitis: POPSTER mixed-methods study

Background

Corticosteroids are a mainstay of the treatment of moderately severe relapses of ulcerative colitis, yet almost 50% of patients do not respond fully to these and risk prolonged steroid use and side effects. There is a lack of clarity about the definitions of steroid resistance, the optimum choice of treatment, and patient and health-care professional treatment preferences.

Objectives

The overall aim of this research was to understand how steroid-resistant ulcerative colitis is managed in adult secondary care and how current practice compares with patient and health-care professional preferences.

Design

A mixed-methods study, including an online survey, qualitative interviews and discrete choice experiments.

Setting

NHS inflammatory bowel disease services in the UK.

Participants

Adults with ulcerative colitis and health-care professionals treating inflammatory bowel disease.

Results

We carried out a survey of health-care professionals (n = 168), qualitative interviews with health-care professionals (n = 20) and patients (n = 33), discrete choice experiments with health-care professionals (n = 116) and patients (n = 115), and a multistakeholder workshop (n = 9). The interviews with and survey of health-care professionals showed that most health-care professionals define steroid resistance as an incomplete response to 40 mg per day of prednisolone after 2 weeks. The survey also found that anti-tumour necrosis factor drugs (particularly infliximab) are the most frequently offered drugs across most steroid-resistant (and steroid-dependent) patient scenarios, but they are less frequently offered to thiopurine-naive patients. Patient interviews identified several factors influencing their treatment choices, including effectiveness of treatment, recommendations from health-care professionals, route of administration and side effects. Over time, depending on the severity and duration of symptoms and, crucially, as medical treatment options become exhausted, patients are willing to try alternative treatments and, eventually, to undergo surgery. The discrete choice experiments found that the probability of remission and of side effects strongly influences the treatment choices of both patients and health-care professionals. Patients are less likely to choose a treatment that takes longer to improve symptoms. Health-care professionals are willing to make difficult compromises by tolerating greater safety risks in exchange for therapeutic benefits. The treatments ranked most positively by patients were infliximab and tofacitinib (each preferred by 38% of patients), and the predicted probability of uptake by health-care professionals was greatest for infliximab (62%).

Limitations

The survey and the discrete choice experiments with patients and health-care professionals are limited by their relatively small sample sizes. The qualitative studies are subject to selection bias. The timing of the different substudies, both before and during the COVID-19 pandemic, is a potential limitation.

Conclusions

We have identified factors influencing treatment decisions for steroid-resistant ulcerative colitis and the characteristics to consider when choosing treatments to evaluate in future randomised controlled trials. The findings may be used to improve discussions between patients and health-care professionals when they review treatment options for steroid-resistant ulcerative colitis.

Future work

This research highlights the need for consensus work to establish an agreed definition of steroid resistance in ulcerative colitis and a greater understanding of the optimal use of tofacitinib and surgery for this patient group. A randomised controlled trial comparing infliximab with tofacitinib is also recommended.

Medication Adherence and Its Influencing Factors Among Inflammatory Bowel Disease Patients in China

Purpose

To investigate the current state of medication adherence among patients with inflammatory bowel disease (IBD) in China and analyze the influencing factors.

Patients and Methods

We recruited as many eligible subjects as possible and a total of 105 patients with IBD finished this cross-sectional survey. The General Information Questionnaire and Morisky Medication Adherence Scale were used as measurement instruments. The factors influencing the Morisky score were studied by multiple linear regression analysis.

Results

The average Morisky score was 6.11 ± 1.93. Univariate analysis showed that there were statistically significant differences in Morisky scores among patients with different ages, education levels, disease types, medication administration methods, medication frequencies, disease understanding and knowledge learning frequencies (P < 0.05). Multiple stepwise linear regression analyses showed that medication frequency, medication administration method and disease understanding were important factors influencing the Morisky score (P < 0.001).

Conclusion

Our data confirmed that the medication adherence of IBD patients was poor, especially among patients taking oral medication, those taking medications with a high frequency and those with a low understanding of the disease. To reduce symptom recurrence and control the disease, medical staff should pay attention to the individual patient factors, simplify the medication regimens, formulate effective coping strategies for drug management support.

Effect of Shenling Baizhu San on Intestinal Flora in a Rat Model of Ulcerative Colitis with Spleen Deficiency and Dampness

OBJECTIVE

Shenling Baizhu San (SLBZS) is reported as an effective drug for ulcerative colitis (UC); however, its effect on intestinal flora remains unknown. In this study, we investigated the effect of SLBZS on intestinal flora in a rat model of UC with spleen deficiency and dampness.

METHODS

UC was induced in rats using 2,4,6-trinitrobenzene sulfonic acid on the basis of a model of spleen deficiency and dampness. The 16S rDNA sequencing was used to detect structural changes in the intestinal flora; the phylogenetic investigation of communities by reconstruction of unobserved state (PICRUSt) analysis was used to predict the altered pathways.

RESULTS

Compared with the model group, rats in the SLBZS group exhibited decreased levels of TNF-α(P < 0.05), and increased abundance and diversity of the intestinal flora. The abundance of Actinobacteria (P < 0.001) and Bacteroides (P < 0.01) increased and that of Firmicutes decreased (P < 0.001), and the abundance of Bifidobacterium(P < 0.05) and Allobaculum increased. PICRUSt analysis showed that the altered pathways between the groups were those of fatty acid and antibiotic biosynthesis, amino acid metabolism, and the pentose phosphate pathway.

CONCLUSIONS

SLBZS can regulate the structure and function of the intestinal flora, alter expression levels of certain metabolic pathways, and has the potential to treat UC.

Upadacitinib Treatment Improves Symptoms of Bowel Urgency and Abdominal Pain, and Correlates With Quality of Life Improvements in Patients With Moderate to Severe Ulcerative Colitis

BACKGROUND AND AIMS

Bowel urgency and abdominal pain are impactful, yet under-appreciated ulcerative colitis symptoms and not commonly assessed in clinical trials. We evaluated how these symptoms may improve with upadacitinib treatment and correlate with clinical and health-related quality of life [HRQOL] outcomes in the phase 2b U-ACHIEVE study.

METHODS

Patients aged 18-75 years, with moderately to severely active ulcerative colitis, were randomised to receive placebo or upadacitinib (7.5, 15, 30, or 45 mg once daily [QD]). Bowel urgency and abdominal pain were evaluated at baseline and Weeks 2, 4, 6, and 8. Week 8 correlations were evaluated between bowel urgency/abdominal pain with clinical [Mayo subscores and high-sensitivity C-reactive protein and faecal calprotectin measurements] and HRQOL outcomes [Inflammatory Bowel Disease Questionnaire and 36-Item Short Form Health Survey scores].

RESULTS

A greater proportion of patients [n = 250] reported no bowel urgency and less abdominal pain with upadacitinib treatment compared with placebo, with improvements observed as early as 2 weeks. At Week 8, patients receiving the 45-mg QD dose had the greatest improvements versus placebo, with 46% reporting no bowel urgency [vs 9%; p ≤ 0.001] and 38% reporting no abdominal pain [vs 13%; p = 0.015]. At Week 8, moderate correlations were found between bowel urgency or abdominal pain and most clinical and HRQOL outcomes.

CONCLUSIONS

Induction treatment with upadacitinib demonstrated significant reductions in bowel urgency and abdominal pain compared with placebo. These symptoms also correlate to clinical and HRQOL outcomes, supporting their use to monitor disease severity and other treatment outcomes.

What Do Influenza and COVID-19 Represent for Patients With Inflammatory Bowel Disease?

BACKGROUND

Inflammatory bowel diseases (IBD) are a group of immune and inflammatory diseases; and patients seem to be more vulnerable to influenza and coronavirus disease 2019 (COVID-19). These conditions are characterized by the augmented release of inflammatory cytokines that have been suggested as potential triggers for the acute respiratory distress syndrome, which may favor severe and even fatal outcomes. For these reasons, this review aims to evaluate what influenza and COVID-19 may represent for patients with IBD.

METHODS

The search was performed in MEDLINE/PubMed, EMBASE, and Cochrane databases. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed to build the review.

RESULTS

The conventional therapies used by IBD patients may also interfere in the outcomes of influenza and COVID-19. Immune-suppressors agents are associated with a higher risk of infections due to the inhibition of intracellular signals necessary to the host act against pathogens. On the other hand, drugs related to the suppression of the production of cytokines in IBD could bring benefits to reduce mucosal inflammation, and for preventing pneumonia. Moreover, coronaviruses can bind to the target cells through angiotensin-converting enzyme 2 (ACE-2) receptor that is expressed in epithelial cells of the lung and largely the colon and the terminal ileum suggesting that human intestinal tract could be an alternative route for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

CONCLUSIONS

Once the cytokine storm observed in influenza and COVID-19 is similar to the cytokine pattern observed in IBD patients during the disease flares, the advice is that avoiding the infections is still an optimal option for IBD subjects.
