Project description:Background and aimElobixibat is a locally acting inhibitor of the ileal bile acid transporter. We compared bile acid metabolism between healthy subjects and patients with chronic constipation and assessed changes in the bile acid profile after elobixibat administration in the latter group.MethodsHealthy subjects (n = 10) and patients with chronic constipation (n = 19) were assessed as inpatients for 7 days, during which they received meals containing ~60 g/day of fat. Patients with chronic constipation remained as inpatients for a further 7 days for once-daily elobixibat administration. Assessments included concentrations of fecal and serum bile acids, serum 7α-hydroxy-4-cholesten-3-one (C4) and fibroblast growth factor 19, and bowel movements and constipation symptoms.ResultsFecal total and primary bile acids were significantly lower in patients with chronic constipation versus healthy subjects. Serum C4 and fibroblast growth factor 19 levels were comparable between groups. Elobixibat treatment increased fecal total and primary bile acids and decreased levels of fecal lithocholic acid and serum total as well as secondary bile acids in patients with chronic constipation. Bowel movements and other constipation-related symptoms were also improved by elobixibat to levels almost comparable with those of healthy subjects.ConclusionsDespite comparable C4 levels, patients with chronic constipation demonstrated decreased levels of fecal bile acids versus healthy subjects. Elobixibat treatment increased fecal bile acid excretion and reduced serum bile acid concentrations. The improvement of constipation after elobixibat treatment was associated with increased total bile acids, particularly primary bile acids.

Project description:BackgroundConstipation is a common, distressing complication in patients with cancer receiving palliative care. Elobixibat is a novel inhibitor of the ileal bile acid transporter that is used to treat chronic constipation by stimulating bowel function. However, its efficacy in patients with cancer has not been examined. This study investigated the drug's effectiveness in patients with cancer with chronic constipation.Patients and methodsThis prospective-sampling, single-center, observational study included hospitalized patients with cancer diagnosed, using the Rome IV criteria, with chronic constipation. Within 2 weeks of hospitalization, each participant was administered elobixibat (5-15 mg) daily until discharge. Spontaneous bowel movements (SBMs), complete spontaneous bowel movements (CSBMs), Bristol stool form scale (BSFS) scores, and the Patient Assessment of Constipation Quality of Life questionnaire (PAC-QOL) scores were assessed before and after elobixibat administration. We also evaluated the relationship between the amount of food consumed and the SBM frequency.ResultsAmong the 83 participants, the mean pre- and post-treatment frequencies of daily SBMs were 0.3 and 1.2 (p < .0001) and those of CSBMs were 0.1 and 0.6 (p < .0001), respectively. The mean pretreatment BSFS score was 1.6, whereas the post-treatment value was 3.5 (p < .0001); the mean PAC-QOL score (overall) improved from 1.01 to 0.74 (p = .01). There was no significant change in the daily SBM frequency between fasting and feeding states (1.2 vs. 1.3; p = .8), and there was no correlation between the amount of food intake and the SBM frequency after elobixibat administration (r = .03). Serious adverse events were not observed.ConclusionThis study showed that elobixibat is safe and effective for patients with cancer with chronic constipation, regardless of the food intake amount.Implications for practiceElobixibat was effective at relieving chronic constipation in patients with various cancers. Serious adverse events were not observed, and the relief of constipation was independent of variation in food intake.

Project description:Background/aimsElobixibat, an ileal bile acid transporter (apical sodium-dependent bile acid transporter) inhibitor, was recently launched in Japan for the treatment of chronic idiopathic constipation. We conducted an interim analysis of post-marketing surveillance to evaluate the safety and efficacy of elobixibat in elderly patients with chronic constipation and compared the efficacy according to administration time.MethodsSafety and efficacy outcomes were evaluated through patient interviews for 4 weeks.ResultsAdverse drug reactions (ADRs) were observed in 5.24% of the 1049 patients analyzed; diarrhea (2.19%) and abdominal pain (1.81%) were the most common. A serious ADR of death was reported in one patient (0.10%). The incidence of ADRs in the ≥ 65-year old or ≥ 75-year-old subpopulation was similar to that in the total patient population. Mean bowel movements per week significantly increased from 2.9 ± 2.5 at baseline to 5.0 ± 3.1 (P < 0.001) at Week 2 and 5.3 ± 2.6 (P < 0.001) at Week 4. The mean Bristol Stool Form Scale score significantly increased from 2.3 ± 1.4 at baseline to 3.8 ± 1.3 (P < 0.001) at Week 2 and 3.9 ± 1.1 at Week 4 (P < 0.001). Bowel movements significantly increased in the elderly population and subpopulations receiving elobixibat before breakfast, lunch, or dinner. The median time to bowel movement was 5 hours.ConclusionThe results suggested that elobixibat was well-tolerated and efficacious in elderly patients with chronic constipation and can be administered before any meals.

Project description:OBJECTIVE:The objective of this study was to evaluate the cost effectiveness of lubiprostone, prucalopride, placebo and immediate referral to secondary care in chronic idiopathic constipation (CIC) in an economic model that was used by the UK National Institute for Health and Care Excellence (NICE) in developing guidance. METHODS:We developed a cohort state-transition model to reflect the treatment pathway in CIC from the UK NHS and personal social services perspective. Time on treatment was determined by a treatment continuation rule using data from an indirect comparison and survival curves fitted to long-term data. Quality of life was defined by whether CIC was resolved or unresolved, using published values. Costs were determined by drug acquisition costs, invasive procedures and healthcare resource use (associated with resolved or unresolved CIC), using published UK sources. Deterministic and probabilistic sensitivity analyses were conducted. RESULTS:Over a 10-year time horizon, lubiprostone was more costly and more effective than placebo and immediate referral to secondary care, with incremental cost-effectiveness ratios (ICERs) of £58,979 and £21,152. Lubiprostone dominated prucalopride in the base case and with a time horizon of 1 year. The main sensitivity for the comparison against placebo was the assumptions around placebo cost and efficacy. The main sensitivity for the comparison against prucalopride was the endpoint used in the indirect comparison. CONCLUSION:Lubiprostone may be cost effective compared with prucalopride or immediate referral but not compared with placebo in the base case. The implementation of the guidance issued by NICE should increase quality of life for patients with CIC and provide a further treatment option.

Project description:IntroductionTo inform the patient-centered discussion regarding comparative outcomes with irritable bowel syndrome/chronic idiopathic constipation pharmacotherapy, we evaluated reasons and timing of discontinuation of FDA-approved pharmacotherapy for irritable bowel syndrome and chronic idiopathic constipation in a large observational real-world cohort.MethodsWe identified patients initiating lubiprostone or linaclotide within the University of Michigan Electronic Medical Record (2012-2016). Medication start and stop dates were determined in manual chart review including detailed review of all documentation including office notes and telephone encounters. A Cox model was constructed to predict the hazard of discontinuation.ResultsOn multivariate analysis of 1,612 patients, linaclotide users had a lower risk of discontinuing therapy than lubiprostone users for any reason (hazard ratio [HR] = 0.6, 95% confidence interval [CI] 0.5-0.8). At 3 and 12 months, the overall discontinuation rates were 23% and 43% for lubiprostone compared with 14% and 24% for linaclotide. Over the first year of therapy, more than half of discontinuations due to intolerance occurred in the first 3 months for both drugs. Linaclotide users were more likely to discontinue due to intolerance (HR = 1.6 [95% CI, 1.2-2.3]) but less likely to discontinue due to insufficient efficacy of therapy (HR = 0.5 [95% CI, 0.4-0.8]). IBS diagnosis increased the hazard of discontinuation of lubiprostone relative to linactolide (HR = 1.4, 95% CI, 1.1-1.6). Loss of prescription drug coverage remained a common reason for discontinuation over the first year of therapy.DiscussionIndividuals appear more likely to discontinue lubiprostone than linaclotide overall, but more likely to discontinue linaclotide compared with lubiprostone due to intolerance (mostly diarrhea). Most discontinuations due to intolerance occur in the first 3 months. These results may be useful in individualized treatment selection and enhancing patient knowledge regarding long-term outcomes.

Project description:AimsTo evaluate the efficacy and safety of elobixibat in patients with diabetes and concomitant chronic constipation.MethodsThis was a single-center, single-arm study. Thirty-three patients with diabetes and chronic constipation, as defined by the Rome IV criteria, were treated with elobixibat (10 mg/day) for 8 weeks. Patients recorded stool properties, including spontaneous bowel movements (SBMs) and stool consistency, according to the Bristol Stool Form Scale (BSFS). Quality of life for constipation was evaluated with the Japanese version of the Patient Assessment of Constipation Quality of Life (JPAC-QOL).ResultsOf the 33 eligible patients, 30 completed the study. Elobixibat significantly increased the median (interquartile range) frequency of SBMs per week, from 5.0 (3.0-7.0) at baseline to 6.0 (4.0-7.0] at week 8 (p = 0.030). After 8 weeks, the BSFS score approached 4; the score for normal stool consistency and the JPAC-QOL score significantly improved from 1.05 ± 0.40 at baseline to 0.94 ± 0.53 (p = 0.048); and glycated albumin and serum lipid profiles significantly improved. Stratified analysis revealed that SBMs increased especially in patients with low SBM frequency, in particular in women, older adults, patients without overweight, patients with a long duration of constipation, and patients with diabetic neuropathy. No serious adverse events occurred.ConclusionsAmong patients with diabetes who met the Rome IV criteria for constipation, elobixibat was effective, especially in those with few SBMs at baseline. Improvements in lipid profiles could be an advantage of elobixibat compared with other laxatives.Clinical trial registryJapan Registry of Clinical Trials registration number: jRCTs031190092.

Project description:AimsElobixibat is a minimally absorbed ileal bile acid transporter inhibitor. This study aimed to investigate the safety, tolerability, efficacy, pharmacokinetics and pharmacodynamics of elobixibat in Japanese patients with chronic constipation.MethodsThis study consisted of single-dose and multiple-dose tests with a dose-escalating design. Sixty patients including females and males were randomized into five dose levels of elobixibat (2.5, 5, 10, 15 or 20 mg, n = 10 per level) and corresponding placebo (n = 2 per group). A crossover design was used to examine food effect in single-dose test. Patients received test tablets once daily for 14 days in multiple-dose test. We assessed pharmacokinetic-dose proportionality, levels of serum high- and low-density lipoprotein cholesterol and plasma 7?-hydroxy-4-cholesten-3-one (C4), food effect and sex-specific effect. Adverse events and bowel functions such as bowel movements, stool consistency and straining were also evaluated.ResultsFood consumption reduced systemic exposure by around 80% [e.g. least squares mean (ratio of breakfast/no breakfast) maximum plasma concentration: 0.2085 (90% confidence interval, 0.1371-0.3172) at 15 mg] while increased plasma C4 level (P < 0.001). In the multiple-dose test, elobixibat reduced low-density lipoprotein cholesterol and increased C4 whilst unaltering high-density lipoprotein cholesterol level. The increased spontaneous bowel movement frequency was correlated with higher dosage and higher C4 level (R2 = 0.5929 at Week 2). Adverse events were mainly gastrointestinal symptoms, most of which were mild.ConclusionsElobixibat should be taken before breakfast. Once-daily administration of elobixibat was found to be safe and tolerated up to 20 mg in female and male patients with chronic constipation.

Project description:Background/aimsWe evaluated the distribution of lower and upper gastrointestinal (GI) symptoms among individuals with irritable bowel syndrome with constipation (IBS-C) and chronic idiopathic constipation (CIC) in a nationwide survey.MethodsIndividuals (≥ 18 years of age) were identified from a nationwide sample of ＞ 70 000 United States adults. Participants completed the National Institutes of Health GI Patient Reported Outcomes Measurement Information System (NIH GI-PROMIS) questionnaire. Symptom frequency and intensity in the prior 7 days were assessed using validated PROMIS scores. Odds ratios (OR) with 95% confidence intervals (CI) were calculated to compare symptom prevalence in IBS-C vs CIC, and one-way ANOVA was used to assess differences in PROMIS scores. Regression analysis was performed to adjust for demographic variables.ResultsNine hundred and seventy adults met eligibility criteria (275 with IBS-C, 734 with CIC). Demographics were similar among groups except for education, marital and employment status, and income. Adjusting for demographic differences, GI-PROMIS scores of global GI symptoms were higher in IBS-C (251.1; 95% CI, 230.0-273.1) compared to CIC (177.8; 95% CI 167.2-188.4) (P ＜ 0.001). Abdominal pain was more prevalent (OR, 4.3; 95% CI, 2.9-6.6) and more severe (P = 0.007) in IBS-C. Constipation was more severe in IBS-C (P = 0.011). Incontinence was more common (OR, 2.9; 95% CI, 1.3-6.3) but just as severe (P = 0.389) in IBS-C versus CIC. Regarding upper GI symptoms, the prevalence of dysphagia, heartburn, and nausea were similar. However, IBS-C individuals had more severe heartburn (P = 0.001).ConclusionGI symptoms are generally more severe in IBS-C compared to CIC, however abdominal pain, bloating, and upper GI symptoms still commonly occur in CIC.

Project description:IntroductionChronic idiopathic constipation (CIC) is a prevalent functional gastrointestinal disorder diagnosed based on patient-reported symptoms and the absence of structural gastrointestinal abnormalities. Individuals with CIC typically institute dietary changes and use stool softeners or over-the-counter (OTC) laxatives, possibly at the direction of a healthcare provider, before prescription medications for CIC are initiated. Although highly prevalent, there is limited information regarding CIC patient experiences with OTC medications.MethodsThis post-hoc analysis used patient-reported data from a questionnaire administered during patient screening for a prospective linaclotide Phase 3b clinical trial in patients with CIC (N = 1482 screened). The questionnaire asked patients to report their experiences with OTC CIC medications over the preceding 6 months.ResultsAmong patients with screening responses (N = 1423), most were female (85%) and white (66%), with a mean age of 48.9 years. A high proportion of patients had used one or more OTC medications (70% had ≥1 OTC; 19% had ≥3 OTCs), with the majority being bisacodyl (33%) and polyethylene glycol (30%). The most commonly cited reason for stopping an OTC medication was insufficient symptom relief (17-40%). The majority of patients taking OTC medications reported no or little satisfaction with the medication's effect on their constipation (62%) and CIC-specific abdominal symptoms (78%). Many patients had little to no confidence in bowel movement (BM) frequency after taking OTC medications and their confidence in their ability to predict BM timing was also low (49-81% not at all confident).ConclusionsTreatment effects on individual CIC symptoms, predictability of bowel habits, and satisfaction with treatment are all important factors for healthcare providers and patients to consider when establishing an effective treatment regimen for CIC.Trial registration numberNCT01642914.
