Active clinical trials for "Irritable Bowel Syndrome"

The purpose of this study is to determine the safety and efficacy of linaclotide administered to patients with Irritable Bowel Syndrome with Constipation (IBS-C).

Our hypothesis is that the medication approved for treatment of high blood cholesterol levels, Colesevelam HCl (WELCHOL), decreases colonic transit and permeability in patients with diarrhea due to irritable bowel syndrome. This effect is thought to result from the effect of the medication on bile acids, which can cause diarrhea.

Patients suffering from Irritable Bowel Syndrome with predominant constipation will be provided with the study medication. The study medication will be evaluated for its efficacy in relieving the symptoms

The purpose of this study is to determine whether a specifically designed multispecies probiotic decreases visceral hypersensitivity in IBS-patient (defined by an increased pain tolerance threshold). Moreover, the effect on general symptom scores and inflammatory and microbiological parameters will be studied.

To test the efficacy of Traditional Chinese Medicine in relieving symptoms and change of quality of life of patients with Irritable Bowel Syndrome.

The treatment of acute pain in patients with irritable bowel symptoms is suboptimal. This is a placebo controlled study of the on demand treatment of pain experienced over a 4 week period in patients with irritable bowel syndrome. Patients will record the severity of pain when they take the study medication and two hours later.

The primary purpose of this study is to evaluate the efficacy and safety of administration of lubiprostone in patients with irritable bowel syndrome with constipation.

The purpose of this study is to evaluate the efficacy of DNK333 compared to placebo for relieving symptoms of IBS-D in female patients.

Irritable Bowel Syndrome (IBS) is the most commonly identified functional gastrointestinal disorder, affecting 10-20% of the population in the Western world, seen predominantly in females and with a negative impact on quality of life, characterized by recurrent and often disabling abdominal pain associated with altered frequency or appearance or passage of the stool. IBS aetiology is unknown and its treatment remains largely empirical and directed to the relief of symptoms. One possible target for IBS treatment has been identified in drugs that modulate the action of Cholecystokinin (CCK), a peptide gut hormone implicated in the regulation of motor and sensory functions at various levels of the gastrointestinal tract. The biological actions of CCK in the gastrointestinal tract are mediated by CCK1-receptors. Dexloxiglumide is an oral potent and selective antagonist of CCK1-receptors. The mechanism by which dexloxiglumide might be beneficial in IBS is its ability to modulate visceral hypersensitivity and gut dysmotility. The DARWIN study has been designed to confirm the efficacy of dexloxiglumide according to a so-called randomized/withdrawal design. In this design all participants start the study treatment and only improved patients (the "responders") are randomized to active treatment or placebo, expecting a more frequent and/or a more rapid relapse of their symptoms in patients randomised to placebo than those on active. Female and male patients, aged 18-70 yrs meeting IBS diagnostic criteria whose main complain is constipation, with a disease of at least moderate severity, will receive dexloxiglumide or placebo during a double-blind treatment phase of 24 weeks, following a first treatment of up to 12 wks during which patients will have to qualify as "responders" to the study treatment. The responder status of each patient over each 4-wk assessment period, will be based on a weekly global patient-based assessment of relief and control of symptoms using a telephone/internet-based diary. Additional secondary efficacy parameters will include: effect of treatment on IBS cardinal symptoms (e.g. abdominal discomfort/pain, bloating, straining, incomplete evacuation, urgency, stool frequency and consistency), on rescue laxative consumption, and on quality of life. Standard safety parameters include vital signs, adverse event reporting, physical examination, routine laboratory screen, 12-lead ECG and gallbladder ultrasound.

We will rigorously test whether modulation of the motor cortex by transcranial direct current stimulation (tDCS) is an effective treatment for patients with chronic pelvic pain through the following specific aims: A) The primary aim of this study is to determine whether transcranial direct current stimulation applied to the motor cortex in patients with chronic pelvic pain induces a significant decrease in the pain or symptoms as compared with sham tDCS. We will also measure changes in the clinical symptom scores of multiple pelvic organs, drug intake (narcotic), anxiety, depression, traumatic stress, as well as overall improvement in the quality of life to assess the effects of this treatment. B) Determine the duration of the clinical effects of tDCS. We will therefore compare the amelioration of pain and related symptoms between active and sham tDCS for one year following treatment. C) Determine whether tDCS changes the threshold for pain detection as compared with sham tDCS. Patients with chronic pelvic pain have a lower threshold for pain as compared to healthy subjects and we hypothesized that this threshold will increase after stimulation with tDCS. D) Finally, we will examine whether 5 days of tDCS treatment is safe for use in chronic pelvic pain patients. Safety will be assessed through neuropsychological tests and adverse event reporting.
