Filter by:Long-standing ulcerative colitis is associated with an increased cancer risk. Chromoendoscopy with dye spraying can detect subtle abnormalities that are not visible with standard endoscopy. The purpose of this study is to determine if chromoendoscopy with fewer "targeted biopsies" can replace standard colonoscopy with multiple "random" biopsies.
The purpose of this study is to evaluate the effectiveness and safety of anti-TNF chimeric monoclonal antibody (cA2) compared to placebo in patients with active Crohn's disease.
The purpose of this study is to evaluate the effectiveness and safety of anti-TNF chimeric monoclonal antibody (cA2) compared to placebo in the treatment of patients with fistulizing Crohn's disease.
Clarithromycin may be an effective therapy in Crohn's disease. It is a broad spectrum antibiotic. Crohn's disease, the investigators think, is in some way related to bacteria, which reside in the bowel. Previous studies of different types of antibiotic in Crohn's disease have shown encouraging results. Clarithromycin alters the bacteria in the bowel and gets into cells in the bowel which may contain bacteria. There is some evidence that clarithromycin can stimulate the immune system and improve the function of cells involved in killing bacteria in the bowel.
The purpose of the study is to evaluate an intravenous (by injection) investigational medication to treat moderate to severe inflammatory, nonstricturing, nonpenetrating Crohn's disease. The research is being conducted at up to 5 clinical research sites in the US and Europe and is open to both men and women ages 18 to 70 years old. Participants in the study will have a number of visits to a research site up to 17 months. All study-related care and medication is provided to qualified participants at no cost: this includes all visits, examinations and laboratory work. Visilizumab is a humanized antibody (antibodies are proteins that are normally made by the immune system to help defend the body from infections and other foreign substances) that is directed against T cells. Visilizumab selectively attacks problematic T cells and, in doing so, it may prevent them from causing inflammation. Visilizumab has also been observed to have a suppressive effect on the body's immune system (system in the body that reacts to foreign or occasionally one's own proteins).
The purpose of the study is to evaluate an intravenous (by injection) investigational medication to treat Crohn's disease in patients with at least one perianal fistula. The research is being conducted at up to 5 clinical research sites in the US and Europe and is open to both men and women ages 18 to 70 years old. Participants in the study will have a number of visits to a research site over a 17 month period.

The purpose of this study is to examine the safety and efficacy of CNTO 1275 in participants with active Crohn's Disease.
This is a study evaluating the long-term safety of infliximab (Remicade)
This study will test whether a new experimental drug called STA-5326 mesylate will decrease inflammatory chemicals called cytokines in patients with Crohn's disease. The drug has prevented gut inflammation in mice and rats and has improved symptoms in humans with active Crohn's disease. Patients with Crohn's Disease between 18 and 75 years of age and who have active disease symptoms may be eligible for this study. Candidates are screened with a review of their medical records, a medical history and physical examination, electrocardiogram, blood and urine tests, chest x-ray and tuberculin skin test. They fill out diary cards for 7 days (measuring their symptoms on the Crohn's Disease Activity Index, or CDAI) and complete a 32-item Inflammatory Bowel Disease Questionnaire (IBDQ) that surveys how their disease affects their live and activities. Participants have a colonoscopy (an examination of the colon using a lighted tube) before starting the study medication. Colon tissue samples are biopsied during the procedure. Following the colonoscopy, patients are randomly assigned to receive either STA-5326 mesylate or placebo (sugar or dummy pill). They take four tablets a day and are seen in the clinic once a week (days 1, 8, 15, 22 and 29) for the following tests and procedures: - Physical examination - Days 1, 8, 15, 22, 29 - Blood tests - Days 1, 8, 15, 22, 29 - Pharmacodynamic study (blood collected before the first dose of medicine and again after 1, 2, 4, 6 and 8 hours to measure levels of the drug in the blood) - Day 1 - CDAI and IBDQ - Days 1, 15, 29 - Review of medications and symptoms - Days 1, 8, 15, 22, 29 - EKG - Days 8, 29 - Pregnancy test for women of child-bearing potential - Days 15, 29 - Urine test - Day 29 After patients complete the above treatment and tests, they undergo a second colonoscopy within 48 hours of their last dose of study medication and may be offered another 1-week supply of medication. Those for whom additional treatment is deemed potentially beneficial are offered another 4-week course of drug or placebo (continuing whichever they took the first 4 weeks). They come to the clinic for two visits 2 weeks apart (days 43 and 57) for a physical examination, blood tests, EKG, pregnancy test for women, CDAI, IBDQ and review of medications and symptoms. A urine sample is collected only on day 57. A third colonoscopy is done after all the tests are completed on day 57, within 48 hours after the last dose of study medication. Patients return to the clinic about 1 week after their final dose of study medication (day 36 for patients who complete only 1 month of treatment and day 64 for those who complete a second month of treatment) for a limited physical examination, blood tests, pregnancy test for women, CDAI and IBDQ, and a review of their medications and symptoms.
