Active clinical trials for "Irritable Bowel Syndrome"

The primary aim of our study is to carry out a randomized trial to evaluate the efficacy of low-FODMAPs dietary therapy compared to conventional therapy for IBS patients recruited from tertiary hospitals in China. Secondary aims of this research include an analysis of clinical, physiological and microbiological factors that may predict IBS patient response to this dietary intervention.

This FTIH study is designed to assess the safety, tolerability and pharmacokinetic (PK) of escalating single and repeat oral doses of GSK3352589 in normal healthy volunteers. This is a randomized, double-blind (sponsor unblinded), placebo controlled, dose escalation study that will have two parts; Part A and Part B.

The objective of this study is to evaluate the safety and efficacy Rifamycin SV-MMX® 600 mg tablets for patients with diarrhoea-predominant irritable bowel syndrome when administered two to three times daily.

The purpose of this study is to investigate placebo effects and peppermint oil in Irritable Bowel Syndrome.

Intestinal microbiota dysbiosis is thought to play an important role in the complex pathophysiology of irritable bowel syndrome (IBS), especially in diarrhoea-predominant IBS and possibly in IBS with severe bloating. Fecal microbiota transplantation or FMT has been shown to be an effective means of correcting this imbalance in the gut microbiota, especially in patients with recurrent Clostridium difficile infections where it has become a preferred treatment strategy. In a preliminary pilot study in 12 patients we found that FMT was a safe and accepted therapy in IBS patients. In 75% of patients an amelioration of IBS symptoms in general and abdominal bloating was seen three months after transplantation. In this study the effects of FMT on patients with IBS without constipation and bloating will be investigated in a double blind, placebo controlled RCT.

The study will characterize the biology of FMT in the context of IBS prior to wider clinical application of the method. Given the ethical concerns of unknown and long-term adverse effects of FMT therapy, the study will include patients only with moderate to severe symptoms. IBS is a heterogenous disorder and it is important to characterize the patients, and study as homogeneous patient populations as possible. Therefore the study will only include post-infectious IBS patients after the Giardia outbreak.

To evaluate the safety and tolerability, treatment effect on abdominal pain, and dose response of MD-7246 administered orally to patients with diarrhea-predominant irritable bowel syndrome (IBS-D).

Irritable bowel syndrom (IBS) is a common chronic gastrointestinal disorder that affects 10-20% of the world population. The prevalence of IBS in Norway is between 8% and 25%. The pathophysiology of IBS is incompletely understood, and there is no effective treatment for this condition. Imbalance (dysbiosis) of the gut microbiome has been found in patients with IBS. In the absence of effective method to restore the dysbiosis, transplantation of a microbiome from healthy individuals with well-functioning gut (FMT) to those with IBS has been performed. Two randomized double blind placebo-controlled (RCT) studies have been published recently. Whereas it was reported in one study that FMT reduced symptom and improved quality of life in patients with IBS, FMT had no effect in the other study. In order to clarify these contradictory results, a new RCT study that enrolled larger number of patients is required. In this study, the investigators intend to recruit 170 IBS patients from those attending outdoor clinic at Stord hospital in a randomized, double blind placebo trial. A single healthy donor with well-characterized microbiome is going to be used. The effects on symptoms, quality of life, fatigue as well as dysbiosis before and after FMT are going to be investigated. The possible mechanisms behind the effects if any of FMT such as changes in intestinal stem cells, enteroendocrine cells and local immune defense shall be also investigated. The patients are going to be randomized either to placebo (own faces), 30 g or 60 g of the donor faces in ratio 1:1:1.

The use of natural bioactive products for prevention and treatment of a wide spectrum of conditions, including gastrointestinal disorders and conditions is well known. Based on current evidences, the scientific validity of such products is limited. However, there is sufficient preliminary data to indicate that bioactive compounds may be novel for potentially clinical use, thus further clinical trials investigating effect are needed. This trial is meant to evaluate the effect of an marine protein hydrolysate (MPH) supplement on composition of microbiota, inflammatory markers and symptom severity in people diagnosed with irritable bowel syndrome.

Irritable bowel syndrome is a functional lower gastrointestinal disorder characterised by abdominal pain and altered bowel habit in the absence of organic pathology to explain the symptoms. Irritable bowel syndrome has a prevalence of approximately 10% in adults, shows a female preponderance, and is more common in younger individuals. In clinical practice, Irritable bowel syndrome accounts for almost a third of all gastroenterology cases seen in primary care, with a subsequent third of these being referred onto secondary-care for further evaluation. The economic burden of Irritable bowel syndrome, in terms of medical expense, work absenteeism and loss of productivity, is considerable. The exact cause of irritable bowel syndrome is unknown. Accordingly there has been a huge surge in interest for dietary therapies to help manage Irritable bowel syndrome. To date, there are only a handful of small randomized controlled trials evaluating the efficacy of dietary therapy in Irritable bowel syndrome. In light of this we plan to conduct the first randomized controlled trial directly comparing the effectiveness of the low-FODMAP diet, British Dietetic Association diet, and the gluten free diet in Irritable bowel syndrome. Moreover, such a trial allows for a direct comparison of nutritional and gut microbial changes, both of which can suffer detrimental consequences following the implementation of restrictive dietary therapies. This study is also unique in that it takes into consideration the patients' perspective with regards to the convenience and cost-effectiveness of implementing such diets into routine day-to-day life. The study will aim to recruit 100 patients from Sheffield Teaching Hospitals gastrointestinal clinics. Following recruitment patients will be seen by a hospital dietitian where they will be randomized to one of the 3 diets. Participants will complete a questionnaire portfolio weekly for one month as part of the study
