Randomized clinical trial: efficacy and safety of plecanatide in the treatment of chronic idiopathic constipation.

ABSTRACT: Background:Plecanatide, with the exception of a single amino acid replacement, is identical to human uroguanylin and is approved in the United States for adults with chronic idiopathic constipation (CIC). This double-blind, placebo-controlled, phase III study evaluated the efficacy and safety of plecanatide versus placebo in CIC. Methods:Adults meeting modified Rome III CIC criteria were randomized to plecanatide 3 mg (n = 443), 6 mg (n = 449), or placebo (n = 445). Patients recorded bowel movement (BM) characteristics [including spontaneous BMs (SBMs) and complete SBMs (CSBMs)] and rated CIC symptoms in daily electronic diaries. The primary endpoint was the percentage of durable overall CSBM responders (weekly responders for ?9 of 12 treatment weeks, including ?3 of the last 4 weeks). Weekly responders had ?3 CSBMs/week and an increase of ?1 CSBM from baseline for the same week. Results:A significantly greater percentage of durable overall CSBM responders resulted with each plecanatide dose compared with placebo (3 mg = 20.1%; 6 mg = 20.0%; placebo = 12.8%; p = 0.004 each dose). Over the 12 weeks, plecanatide significantly improved stool consistency and stool frequency. Significant increases in mean weekly SBMs and CSBMs began in week 1 and were maintained through week 12 in plecanatide-treated patients. Adverse events were mostly mild/moderate, with diarrhea being the most common (3 mg = 3.2%; 6 mg = 4.5%; placebo = 1.3%). Conclusions:Plecanatide resulted in a significantly greater percentage of durable overall CSBM responders and improved stool frequency and secondary endpoints. Plecanatide was well tolerated; the most common AE, diarrhea, occurred in a small number of patients.[ClinicalTrials.gov identifier: NCT02122471].

Project description:IntroductionChronic constipation is associated with various comorbidities and reduced quality of life. Current solutions, either pharmacological or invasive, show limited efficacy. Manual colon-specific massage is a well-established intervention to treat chronic constipation, but it should be applied daily. MOWOOT automatically provides intermittent colonic exo-peristalsis (ICE) treatment like that in manual massage.MethodsThis study assessed the safety and effectiveness of the ICE device to treat chronic constipation due to neurogenic bowel dysfunction or idiopathic causes with high component of pelvic floor disorders. The ICE device was used daily for 20 minutes over 4 weeks. Each participant was followed for 9 consecutive weeks. The same outcome measures (primary: complete bowel movements per week; secondary: Knowles Eccersley Scott Symptom Score and Patient Assessment of Constipation Quality of Life among others) were assessed at baseline (V1), last intervention weeks (V2), and post-treatment (V3). Responders were defined for selected outcomes as better results at V2 respect to V1.ResultsN = 92 adult patients constituted the intention-to-treat population, with N = 65 as the per protocol population. Adherence (quantity of treatment received) was ≥95% in the intention-to-treat population. Adverse events related with the treatment were low (8.7%). Using the device significantly increased the number of complete bowel movements per week (V2 - V1 = 1.8 [2.7], P < 0.0001), reduced the symptoms of chronic constipation (Knowles Eccersley Scott Symptom Score V2 - V1 = -3.9 [5.0], P < 0.0001), improved quality of life (Patient Assessment of Constipation Quality of Life V2 - V1 = -0.7 [0.8], P < 0.0001), and facilitated a reduction in laxatives. Colon transit and fecal consistency were not modified. There was a high number of responders (>70%).DiscussionConsidering safety, adherence, and efficacy being demonstrated, the results favor the use of MOWOOT to treat chronic constipation (Visual abstract, Supplementary Digital Content 1, http://links.lww.com/CTG/A440).(Equation is included in full-text article.).

Project description:BackgroundFunctional constipation (FC) is one of the prevalent gastrointestinal disorders that affect people of all ages. Long-term FC has significant effects on the quality of life of patients. Although commonly used drugs have reliable short-term effects, they are easily addictive and have side effects. Therefore, pursuing a convenient drug-food homogenous program is critical for FC patients. Maxing Xianchang Su is a functional food based on traditional Chinese medicine. To investigate the efficacy and safety of Maxing Xianchang Su in FC treatment, we conducted a randomized controlled trial.MethodsWe carried out a prospective multicenter randomized parallel controlled study in three hospitals in Jiangsu Province, China, from January 2020 to March 2021, which included 206 FC patients. All patients were arbitrarily assigned into a treatment group and a control group at a ratio of 1 : 1; 103 cases in each group. The treatment group was given oral Maxing Xianchang Su, whereas the control group was treated with lactulose oral solution. The course of treatment was two weeks. The two groups of patients were evaluated after six weeks for symptom improvement before and after taking the drug. Furthermore, the safety of Maxing Xianchang Su was assessed.ResultsBoth groups of patients successfully completed the study without shedding cases. The effective rates of the treatment group and control group after two weeks were 90.6% and 67.0%, respectively. The treatment group had a better curative effect than the control group (P < 0.05). The symptom score of the two groups improved compared with that before the treatment. The difference between the two groups was statistically significant (P < 0.05). During the treatment process, neither group experienced abnormal changes in blood lipid, blood glucose, routine hematuria, or liver and kidney functions. There were no adverse reactions in both groups.ConclusionMaxing Xianchang Su has a positive effect on FC treatment with reliable mid-term effect and a high level of safety.

Project description:BackgroundAbdominal bloating is a common and bothersome symptom of chronic idiopathic constipation. The objective of this trial was to evaluate the efficacy and safety of linaclotide in patients with chronic idiopathic constipation and concomitant moderate-to-severe abdominal bloating.MethodsThis Phase 3b, randomized, double-blind, placebo-controlled clinical trial randomized patients to oral linaclotide (145 or 290 μg) or placebo once daily for 12 weeks. Eligible patients met Rome II criteria for chronic constipation upon entry with an average abdominal bloating score ≥5 (self-assessment: 0 10-point numerical rating scale) during the 14-day baseline period. Patients reported abdominal symptoms (including bloating) and bowel symptoms daily; adverse events were monitored. The primary responder endpoint required patients to have ≥3 complete spontaneous bowel movements/week with an increase of ≥1 from baseline, for ≥9 of 12 weeks. The primary endpoint compared linaclotide 145 μg vs. placebo.ResultsThe intent-to-treat population included 483 patients (mean age=47.3 years, female=91.5%, white=67.7%). The primary endpoint was met by 15.7% of linaclotide 145 μg patients vs. 7.6% of placebo patients (P<0.05). Both linaclotide doses significantly improved abdominal bloating vs. placebo (P<0.05 for all secondary endpoints, controlling for multiplicity). Approximately one-third of linaclotide patients (each group) had ≥50% mean decrease from baseline in abdominal bloating vs. 18% of placebo patients (P<0.01). Diarrhea was reported in 6% and 17% of linaclotide 145 and 290 μg patients, respectively, and 2% of placebo patients. AEs resulted in premature discontinuation of 5% and 9% of linaclotide 145 μg and 290 μg patients, respectively, and 6% of placebo patients.ConclusionsOnce-daily linaclotide (145 and 290 μg) significantly improved bowel and abdominal symptoms in chronic idiopathic constipation patients with moderate-to-severe baseline abdominal bloating; in particular, linaclotide significantly improved abdominal bloating compared to placebo, an important finding given the lack of agents available to treat abdominal bloating in chronic idiopathic constipation patients.Trial registrationClinicalTrials.gov NCT01642914.

Project description:ImportanceIndividuals living with schizophrenia are affected by cardiometabolic, endocrine, and motor adverse effects of current antipsychotic medications. Lumateperone is a serotonin, dopamine, and glutamate modulator with the potential to treat schizophrenia with few adverse effects.ObjectiveTo examine the efficacy and safety of lumateperone for the short-term treatment of schizophrenia.Design, setting, and participantsThis randomized, double-blind, placebo-controlled, phase 3 clinical trial was conducted from November 13, 2014, to July 20, 2015, with data analyses performed from August 13 to September 15, 2015. Patients with schizophrenia who were aged 18 to 60 years and were experiencing an acute exacerbation of psychosis were enrolled from 12 clinical sites in the United States.InterventionsPatients were randomized 1:1:1 (150 patients in each arm) to receive lumateperone tosylate, 60 mg; lumateperone tosylate, 40 mg (equivalent to 42 or 28 mg, respectively, of the active moiety lumateperone); or placebo once daily for 4 weeks.Main outcomes and measuresThe prespecified primary efficacy end point was mean change from baseline to day 28 in the Positive and Negative Syndrome Scale (PANSS) total score vs placebo. The key secondary efficacy measure was the Clinical Global Impression-Severity of Illness (CGI-S) score. The PANSS subscale scores, social function, safety, and tolerability were also assessed.ResultsThe study comprised 450 patients (mean [SD] age, 42.4 [10.2] years; 346 [77.1%] male; mean [SD] baseline PANSS score, 89.8 [10.3]; mean [SD] baseline CGI-S score, 4.8 [0.6]). In the prespecified modified intent-to-treat efficacy analysis (n = 435), 42 mg of lumateperone met the primary and key secondary efficacy objectives, demonstrating a statistically significant improvement vs placebo from baseline to day 28 on the PANSS total score (least-squares mean difference [LSMD], -4.2; 95% CI, -7.8 to -0.6; P = .02; effect size [ES], -0.3) and the CGI-S (LSMD, -0.3; 95% CI, -0.5 to -0.1; P = .003; ES, -0.4). For 28 mg of lumateperone, the LSMD from baseline to day 28 was -2.6 (95% CI, -6.2 to 1.1; P = .16; ES, -0.2) on the PANSS total score and -0.2 (95% CI, -0.5 to 0.0; P = .02; ES, -0.3) on the CGI-S. Both lumateperone doses were well tolerated without clinically significant treatment-emergent motor adverse effects or changes in cardiometabolic or endocrine factors vs placebo.Conclusions and relevanceLumateperone demonstrated efficacy for improving the symptoms of schizophrenia and had a favorable safety profile.Trial registrationClinicalTrials.gov identifier: NCT02282761.
