Active clinical trials for "Crohn Disease"

This is an open-label extension study designed to measure the safety, efficacy, and corticosteroid-sparing effect of certolizumab pegol (CDP870) in patients with moderate to severe Crohn's disease previously enrolled in C87059 (COSPAR I, NCT00349752).

Evaluate the response of inflammatory serum markers to oral ERB-041 in subjects with inflammation associated with active Crohn's disease.

his study will explore the safety and activity of ECP treatment with UVADEX in inducing a clinical response (i.e., a CDAI decrease greater than or equal to 100 from baseline and/or a CDAI < 150) over a 12-week period in moderately active Crohn's disease (CDAI greater than or equal to 220 to < 450) patients who are refractory or intolerant to immunosuppressants and/or anti-TNF agents. This study will also assess response to continued treatment during a 12-week Extension Period in patients who have a clinical response at Week 12 of the Treatment Period and elect to participate in the Extension Period.

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 this research study is to investigate the effects of an investigational medication, called CCX282-B, on safety and on the some of the symptoms of Crohn's Disease in patients who are experiencing an active flare-up of moderate to severe Crohn's Disease.

The purpose of this study is to assess the safety and effectiveness of three different treatments for patients with Crohns disease who have not responded to previous treatment with a group of drugs commonly used to treat Crohn's Disease (5-ASA) and corticosteroids. Patients will receive either infliximab (a drug used to treat autoimmune diseases) or azathioprine (an immunosuppressant or drug used to suppress the immune system) or a combination of both for up to 34 weeks. This research study will involve approximately 500 patients. The main study involves up to 34 weeks (approximately 8 months). A study extension of an additional 20 weeks (approximately 5 months) is optional for patients who successfully complete the main study. A country-specific study extension of open label infliximab treatment for an additional 1 year is optional for patients who successfully complete the main study extension.

This study will examine the safety and effectiveness of extracorporeal photopheresis (ECP) in controlling Crohn's disease symptoms as patients taper their corticosteroid dose. Crohn's disease is a chronic inflammatory bowel disease. Patients commonly have chronic diarrhea with abdominal pain, loss of appetite and weight loss. Acute disease flares are treated with large doses of corticosteroids, but long-term use of these drugs can have harmful side effects. ECP (described below), is approved to treat skin symptoms associated with a type of cancer called cutaneous T-cell lymphoma and has been used experimentally in conditions involving abnormal inflammation. Patients 18 years of age and older who have had Crohn's disease for at least 6 months, who are corticosteroid-dependent, and whose symptoms are controlled well enough so that their Crohn's Disease Activity Index (CDAI) is less than 220, may be eligible for this study. Candidates will be screened with a medical history and review of medical records, physical examination, electrocardiogram, blood tests, urine pregnancy test for women of childbearing potential, and a questionnaire about how Crohn's disease affects their life and activities. Patients with a CDAI score of less than 150 will begin ECP treatments as soon as possible. Those with scores from 150 to 219 will have their corticosteroid dose increased enough to bring their CDAI score to below 150 before beginning ECP. Patients who do not achieve a CDAI of less than 150 after 4 to 6 weeks of increased corticosteroids will be excluded from the study. Participants will have ECP treatments for 2 consecutive days every 2 weeks for 24 weeks, for a total of 26 treatments. For ECP, patients undergo leukapheresis, a method of collecting large numbers of white blood cells, or leukocytes-cells that may be responsible for many of the medical problems in Crohn's disease. Whole blood is collected through a needle in an arm vein, similar to donating a unit of blood. The blood flows through a machine that separates it into its components by spinning. The white cells are removed and collected in a plastic bag, and the red blood cells and plasma are returned to the patient's bloodstream through the same needle. The collected white cells are mixed with a drug called UVADEX® (Registered Trademark), exposed to ultraviolet (UVA) light, and then returned to the patients' bloodstream. (The UVADEX allows the blood cells to absorb more UVA.) The UVA changes the cells in a way that, once they are back in the body, they cause changes in other cells like them. Each ECP treatment takes 3 to 4 hours. On the first day of each 2-day treatment, patients will undergo a review of symptoms, check of vital signs, and blood draw. They will complete a CDAI diary for 7 days before the first of the two ECP treatments and a questionnaire about their life and activities at 4-week intervals. During the ECP treatment period, corticosteroids will be slowly reduced as long as disease symptoms do not worsen. Patients whose disease remains under control with cessation of all steroids may begin maintenance ECP, 2 days in a row every 4 weeks for an additional 20 weeks (another 10 treatments), with the same follow-up as described above, and a full physical examination 4 weeks after the final treatment. Patients who were able to reduce, but not stop, steroid treatment may be considered for maintenance therapy if it is thought that continuing treatment may enable further reduction of steroids. Patients whose disease symptoms worsen with ECP or who have not been able to decrease their steroid dose will not be eligible for maintenance therapy and their participation in the study will end.

The purpose of this trial is to evaluate natalizumab in individuals with moderately to severely active Crohn's Disease.

The purpose of this study is to determine the safety and tolerability of natalizumab in adolescents (ages 12-17) diagnosed with moderately to severely active Crohn's disease (CD). It is thought that natalizumab may stop the movement of certain cells, known as white blood cells, into bowel tissue. These cells are thought to cause damage in the bowel leading to the symptoms of Crohn's disease. Patients who complete this study may be eligible for long-term natalizumab therapy via extension protocol ELN100226-352.

The purpose of this study is to determine the safety, tolerability, and efficacy of natalizumab in individuals diagnosed with active Crohn's Disease that are not in remission (CDAI greater than/equal to 150) and are currently taking Remicade. It is thought that natalizumab may stop the movement of certain cells, known as white blood cells, into bowel tissue. These cells are thought to cause damage in the bowel leading to the symptoms of Crohn's disease. Patients who complete this study may be eligible for long-term natalizumab therapy via extension protocol ELN100226-351.
