Active clinical trials for "Ulcer"

Venous leg ulcers are a common, costly and debilitating condition, with few effective treatments. Compression bandaging helps healing, but more than four out of every ten leg ulcers remain unhealed after three months. New treatments to help heal venous ulcers are urgently needed. Initial studies with a new drug product candidate called Nexagon® (developed by CoDa Therapeutics, Inc.) have shown improvements in healing when applied topically to a wound. Further research will be undertaken to assess the safety and activity of Nexagon® when applied to venous leg ulcers in humans, and to obtain further information on the most appropriate dose or doses to apply. A proposed randomised controlled trial aims to further evaluate Nexagon® by randomly allocating (e.g., by the toss of a coin) 90 people with venous leg ulcers to Nexagon® (one of two different doses) or a vehicle (substance containing no medication) to be applied to their ulcer three times over four weeks. Participants will be followed up for 12 weeks to evaluate ulcer healing.

Ulcerative colitis is characterized by abnormal activation of, and damage to, the colon epithelium, which is considered to be a central pathogenic mechanism. Activation of colon epithelium cells in UC is associated with an abnormal high expression of Toll-like receptors, including TLR-4, the major transducer of LPS, binding specifically the lipid A portion of LPS. Alkaline Phosphatase binds and subsequently dephosphorylates LPS, thereby eliminating the ability of LPS to activate TLR-4. This is expected to 1) prevent activation of the intestinal epithelium and 2) prevent systemic inflammatory responses that result from transmigration of endotoxin though the leaky inflamed intestinal mucosa. Therefore, it is expected that administration of BIAP may attenuate or prevent the local and systemic inflammatory response in patients with severe ulcerative colitis.

The purpose of this study is to compare the safety and effectiveness of dosing mesalazine 800 mg tablets (Asacol®) at 2.4 g once daily versus divided doses three times daily in the maintenance of remission of ulcerative colitis.

Several open-label studies reported thalidomide efficacy in inducing clinical remission and steroid tapering in refractory Inflammatory Bowel diseases (IBD), both in adults and in children. This is a randomized placebo controlled (RCT) double blind study, to evaluate the efficacy of thalidomide in inducing clinical remission at 8 weeks in refractory IBD patients aged 2-20 years. The primary hypotheses of the study is that thalidomide would be more effective than placebo in inducing clinical remission. The RCT phase is followed by a open-label phase, to further evaluate efficacy and safety of thalidomide in thalidomide responders, with a total follow up of one year.

Objective of this study was to determine incidence, risk factors, etiological micro-organisms and their antimicrobial susceptibility pattern and outcome of VAP; and to study effect of ranitidine vs. sucralfate, used for stress ulcer prophylaxis, on gastric colonization and on occurrence of VAP. Methods: Design: Prospective randomized study. Setting: ICUs of Medicine Department and Anesthesiology Department, Maulana Azad Medical College and Lok Nayak Hospital, University of Delhi, New Delhi. Patients: 50 patients of age more than 12 years, who had been on ventilator for more than 48 hrs. Intervention: Endotracheal Aspirate and blood sample of all patients were cultured to determine micro-organisms causing VAP and their antimicrobial susceptibility pattern. Patients were divided into 2 groups on random basis. The first group was given ranitidine for stress ulcer prophylaxis while the second was given sucralfate. Thereafter, difference in gastric colonization (on basis of quantitative culture of nasogastric aspirate) and on occurrence of VAP in both the groups was compared. Study Hypothesis: Study was designed to create data about Ventilator associated pneumonia in developing countries like India. This data is crucial for providing information for deciding future guidelines for treatment of and prevention of Ventilator associated pneumonia. Further to test the hypothesis that H2 blockers, by virtue of raising gastric Ph, increase gastric colonization by pathogenic organism and increase incidence of Ventilator associated pneumonia; patients were divided into two groups on random basis, as described above.

The purpose of this study is to prove the therapeutic equivalence and safety of once-daily 9 mg budesonide versus 3 g mesalazine in a 8-week treatment in patients with active ulcerative colitis.

the objective of this investigation is to demonstrate the effect of the foam dressing Biatain Ag, compared to Biatain foam dressing( a product which is similar but does not contain a silver complex, in the healing of leg ulcers that had failed to heal despite appropriate therapy

To evaluate the efficacy of the product Bismu-Jet ® (bismuth tartrate and sodium, neomycin sulfate and procaine hydrochloride) produced by EMS S / A compared to placebo in reducing the signs and symptoms resulting from UAR in patients of both sexes, with age over 12 years.

Some leg ulcers do not seem to respond that well to the standard treatments that we currently use. One reason for this may be that there are high levels of bacteria in the ulcer which may be slowing down the rate of healing. Because we need to be careful about when we use antibiotics, this study will look at another way of killing bacteria in the ulcer. This new method involves putting a special gel on the ulcer and then shining a particular type of light (visible red light) onto the ulcer for a short period of time. In the first part of the study, a single treatment with the gel and light will be investigated. The second part of the study will compare whether or not using the treatment once a week for 12 weeks is better than placebo. Across the UK 57 people with chronic leg ulcers will be asked to take part in this study (9 in part 1 and 48 in part 2). Up to 10 sites will be involved including Cardiff University and hospitals in Bradford, Harrogate, Dundee, Hull, Plymouth and the Wirral. The research is funded by Photopharmica Ltd.

The purpose of this study is to compare the efficacy in maintaining remission of ulcerative colitis between a once daily (QD) Asacol regimen and a divided, twice daily (BID) Asacol dosing regimen.
