There are about 25435 clinical studies being (or have been) conducted in United Kingdom. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The protocol described herein is designed to provide clinical evidence of the substantial equivalence of SmartPill GI Monitoring System (SP) to the Sitzmarks (Konsyl Pharmaceuticals, Easton, MD) radio-opaque markers (ROM). The trial will enroll symptomatic subjects who meet Rome III criteria (1) for chronic functional constipation.
Urethral dilatation is a commonly undertaken intervention for a variety of urinary complaints including overactive bladder symptoms. There is however very little evidence for its efficacy, and no randomized trial evidence. The aim of this study is to ascertain the effect of urethral dilatation on overactive bladder symptoms and on voiding parameters. The null hypothesis is that there will be no difference in symptoms or voiding parameters between the urethral dilatation and sham groups. Eligible women will be assessed initially with a history and examination, a King's Health Questionnaire and Bristol Female Urinary Tract Symptoms (BFLUTS) questionnaire and pressure flow studies. They will be randomized to undergo either cystoscopy alone or cystoscopy and urethral dilatation. Patients will be blinded to the procedure undertaken and randomized using a series of opaque envelopes. Follow up will be at 6 weeks with repeat questionnaires and pressure flow studies. Subjective and objective outcomes will be compared between the two groups.
The purpose of the study is to generate a library of functional imaging and anatomical imaging for patients with head and neck cancers for evaluation of new radiotherapy strategies and planning techniques including IMRT. Secondary aims would be to observe the changes in the cancers as the treatment progresses as well as to define the biologically most active part of the tumor (biological target volume) which could be given more intensive treatment. Tumor volumes seen on different imaging modalities will be compared with a hope of finding an optimal imaging methodology for accurate visualization of the head and neck cancers
Due to the potential for pregnancy-induced changes in the pharmacokinetics of medication, one cannot assume that the currently licensed doses of the medication to be tested under this protocol lead to adequate exposure in an HIV-infected pregnant woman. For the agents under study no or limited pharmacokinetic data during pregnancy are available. As the changes in pharmacokinetics during pregnancy are most prominent in the third trimester a pharmacokinetic curve will be recorded in the third trimester after attaining steady state.
the principal research objective is to form a database of tissue samples from patients with colorectal (bowel) cancer. The tissue samples that will be used for this research will have already been taken for diagnostic or therapeutic reasons. We will also be asking for consent for a research blood sample. The database will be used to improve our understanding of the molecular genetics and gene expression patterns in colorectal cancer.
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Specialized radiation therapy, such as intensity-modulated radiation therapy, that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. It is not yet known which radiation therapy schedule is more effective in treating breast cancer. PURPOSE: This randomized phase III trial is studying three different radiation therapy schedules to compare how well they work in treating women who have undergone breast conservation surgery and systemic therapy for early breast cancer.
Study part-1 GIP (glucose-dependent insulinotropic polypeptide) is one of the two main incretin hormones secreted by specialized cells of the gastrointestinal tract in response to ingestion of nutrients. Data emerging from studies in animal models and cultured human fat cells support a physiological role for GIP in the adipose tissue metabolism which may contribute to the pathogenesis of obesity. The proposed study will shed more light on the interactions between gut hormones and adipose tissue. For this pilot study, male subjects fulfilling the inclusion criteria will be given GIP or placebo infusions in a randomized manner. Fat tissue biopsies will be obtained from all subjects during both visits, once in the basal state (before the start of the peptide/placebo infusion) and then repeated at the end of the period of infusion. Study part-2 Surgery represents the most effective therapeutic modality for morbid obesity. Resolution of type 2 diabetes mellitus (T2DM) has been consistently observed as an additional benefit of surgical treatment of obesity. The mechanisms underlying the dramatic effects of surgery on insulin sensitivity and β-cell function are poorly understood. Bariatric surgery (gastric bypass) promotes changes in the enteroendocrine system as a result of nutrient diversion from the physiological intestinal routes with subsequent profound modification of gut hormone secretion We hypothesize that restoration of GIP action after bariatric procedures plays a cardinal role in the improvement and/or restoration of diabetes, we propose to study patients (both sex)with morbid obesity and T2DM within 3 months after their surgery. Their responses will be compared to those of BMI matched control subjects with normal glucose tolerance
Primary: To compare the analgesic effect over 12 weeks of topical 2PX in stump pain. Secondary: To prospectively measure other efficacy and safety variables of topical 2PX in stump pain. Exploratory analyses will be performed to measure efficacy and safety variables of topical 2PX in phantom pain
The purpose of this study is to assess the effects of a novel beverage rich in polyphenols (compounds present in fruit extracts) on risk factors associated with cardiovascular disease.
This is a global, multicenter, open-label safety extension study. Participants receiving single-agent trastuzumab emtansine or trastuzumab emtansine administered in combination with other anti-cancer therapies in a Genentech / Roche-sponsored parent study who are active and receiving benefit at the closure of parent study are eligible for continued treatment in this study.
