Active clinical trials for "Constipation"

The purpose of this study was to evaluate the efficacy and safety of oral administration of lubiprostone 24 μg twice daily (BID) for 4 weeks in participants with chronic idiopathic constipation (CIC) compared with placebo.

The purpose of this study is to determine the effect of NGM282 on colonic transit, bile acid homeostasis, and fecal fat in subjects with functional constipation and healthy individuals.

The primary objective is to determine the change in frequency of complete spontaneous bowel movements (CSBMs) after 4 weeks of oral supplementation with Lactobacillus gasseri DSM 27123 in healthy adult women with functional constipation.

The objectives of this study are to evaluate the safety, efficacy, and dose response of two delayed release formulations of linaclotide (DR; DR formulation 1 is DR1; DR formulation 2 is DR2) administered orally to patients with irritable bowel syndrome with constipation (IBS-C). Additional objectives include understanding how the two DR formulations compare with each other and with the FDA-approved 290 μg LINZESS® (the immediate release [IR] formulation of linaclotide).

Investigation of the effects of a four week daily consumption of Orafti® Inulin on bowel motor function in subjects with constipation.

Rationale: Previous reviews showed that the evidence regarding the effectiveness of sacral neuromodulation (SNM) in patients with therapy-resistant, idiopathic (slow-transit) constipation is of suboptimal quality. Furthermore, there is no estimate of costs and cost-effectiveness in this patient group. Objective: The main objective of this study is to assess the effectiveness of SNM compared to personalized conservative treatment (PCT), in patients with idiopathic slow-transit constipation who are refractory to conservative treatment. The secondary objectives are assessing the 1) costs, 2) cost-effectiveness and 3) budget-impact of SNM compared to PCT. Hypothesis: Based on previous research we hypothesize that SNM will be more effective than PCT in terms of a significantly higher proportion of patients having treatment success at 6 months. Study design: An open-label pragmatic randomized controlled trial (RCT) combined with a prospective cohort study. Study population: Adolescent (14-17 years) and adult (18-80 years) patients with idiopathic slow-transit constipation refractory to conservative treatment. Intervention: The intervention is SNM, a minimally invasive surgical procedure consisting of two phases. In the screening phase an electrode is inserted near the third sacral nerve and connected to an external stimulator. If the screening phase is successful (average defecation frequency (DF) ≥3 a week), the electrode is connected to a pacemaker that is implanted in the buttocks of the patient. If not successful, patients receive conservative treatment. The control intervention is PCT. This is the best and least invasive alternative to SNM. PCT consists of medication and/or retrograde colonic irrigation. Main study parameters/endpoints: The primary outcome is success at 6 months, defined as an average DF of ≥3 a week according to a 3-week defecation diary. Secondary outcomes are straining, sense of incomplete evacuation, constipation severity, fatigue, constipation specific and generic (health-related) quality of life ((HR)QOL), and costs at 6 months. Furthermore, cost-effectiveness and budget-impact will be estimated.

It is a double-blinded, randomized, placebo-controlled trial for advanced cancer patients with constipation. 60 patients will be randomly assigned to have individualized herbal intervention (treatment group) or placebo (control group) in 1:1 ratio. For the treatment group, MaZiRenWan 10g plus HuangQi 20g are chosen as the core prescription. Furthermore, six herbal granules can be added according to the syndrome differentiated for individual participant. Placebo is made from dextrin (76.03%), tea essence (23.61%), gardenin (0.02%), and caramel (0.34%) to achieve color, smell, taste, and texture comparable to the herbal granules. Patients are instructed to dissolve the granules in 150ml of hot water, twice daily for two weeks. The primary end point is the global symptom improvement. Secondary outcome measures include stool frequency, stool form, use of rescue herbal granules, constipation visual analogue scale (CVAS) (0=none to 7=most severe) and individual assessment of constipation related symptoms. For the safety profiles of herbal intervention, the important adverse events reported and clinical laboratory evaluations of liver and renal function are determined.

The objective of this study is to verify the efficacy and investigate the safety of the study drug when ASP0456 is administered orally for 4 weeks and 52 weeks.

This is a study to determine the safety and tolerability of a new medicine (RQ10) for gastrointestinal symptoms in Parkinson's disease. The investigators will also begin to look at the effect of this medicine on gastrointestinal problems. The results will determine if future studies are appropriate. In this study, RQ10 will be compared to a placebo (a look-alike inactive substance). Participation will include multiple office visits. Approximately 48 people will participate.

The research is a collaborative project by HKU and Yan Chai Hospital, funded by Social Welfare Development Fund of HKSAR. The study is designed as a prospective randomized control trial with the primary objective to investigate the efficacy of pediatric tuina (massage) on the functional constipation of pre-school aged children. Our study is a pragmatic research comparing the pediatrictuina(massage)treatment with care as usual, with the objectives of investigating if a non-invasive, easy to learn pediatrictuina (massage) protocol could improve the constipation and related symptoms experienced by the pre-school age children if there is a positive impact on the caregiver-children relationship and the children's behaviour (a sub-group analysis) when the constipation symptoms improved. The subjects of this study are pre-school age children (age 2-6) who are serviced by Yan Chai Hospital Social Service Department (YCHSS).The subjects will be openly recruited through the service units serving pre-school aged children under YCHSS. Rome IV criteria will be used to identify the children who suffer from constipation. I. Trial Design This is a multicentre, pragmatic randomized control trial (PRCT) with a prospective design Hypothesis 1: Applying regular pediatrictuina (massage) (3 times a week, for 4 weeks ) on pre-school aged children with functional constipation will improve one or more of the following symptoms. Frequency of defecations Episode of incontinence Excessive stool retention Painful or hard bowel movements Presence of a large fecal mass in the rectum that may obstruct the toilet Hypothesis 2: The stress level of the caregiver of the study subjects improve as the constipation syndrome of the subjects improve. Hypothesis 3: The children with behavior problem who suffered from constipation will have less behavior issue when their functional constipation syndromes improved Total 160 pre-school aged children with functional constipation and their caregiver will be openly recruited from the institutions/service units operated by the pediatric service unit of Yan Chai Hospital Social Service Department.The recruited children must suffer from functional constipation symptoms (based on Rome IV criteria). All accepted subjects will be in dyad. (i.e. 1 pre-school aged child and his designated caregiver, who commits bring the child to attend all treatment and assessment sessions, respond to all caregivers' assessment and fill in the daily logbook). All applications will be screened by the social workers in the centres based on the inclusion and exclusion criteria. Qualified applicants will be invited for a health assessment conducted by registered TCM practitioner in the research team to confirm their suitability and invite them to sign the consent form. The consented dyad will be allocated randomly into treatment group and waitlist control group. II. Intervention A 10 minutes structured pediatric massage protocol with specific applications technique will be performed on the children allocated to the treatment group three times a week for 4 consecutive weeks by trained TCM practitioners in the service units of YCHSS. The caregivers of the children need to participate in all assessment sessions and fill in the log book provided. In the 1st 4 weeks, the children in the waitlist control group will not receive any pediatrictuina (massage). After the dyad completed the assessment sessions at baseline and week 4 ,(served as Treatment-as-Usual Control), children in the control group will receive the same 4 weeks of pediatric massage as the treatment group. The data collected before the treatment begins at week 4 will serve as the 2nd baseline for the waitlist control group. The treatment protocol involve 8 steps.The massage area focuses on the abdomen and lower back of the recipients. All the movements/steps selected are well established and commonly used in the TCM practices. Any movement that demand professional training or involve potential risk is excluded from the protocol. III. Measurement of efficacy Efficacy of the treatments will be measured in multi dimensions before and after the treatment for both groups. The main outcome measures are defecation frequency per week, fecal incontinence frequency per week, and overall treatment success after 4 weeks intervention, 8 weeks intervention and 12 weeks (4 weeks after intervention stopped) Secondary outcome measures included abdominal pain and painful defecation based on bowel diary, the children's subjective level of pain during bowel movement, score of child behavior questionnaire and score of caregiver impact and burden
