Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00063414 ↗	ISIS 2302-CS22, A 6-Week, Active-Controlled Clinical Study to Evaluate the Effectiveness of Alicaforsen (ISIS 2302) in Patients With Mild to Moderate Active Ulcerative Colitis	Completed	Ionis Pharmaceuticals, Inc.	Phase 2	1969-12-31	This is a multi-center trial to test the safety, efficacy and tolerability of alicaforsen (ISIS 2302), a new type of drug called an antisense drug, in patients with mild to moderate active Ulcerative Colitis (UC). Alicaforsen is designed to reduce the production of a specific protein, called ICAM-1, a substance that plays a significant role in the increase of inflammation and is likely to be involved in inflammatory bowel diseases such as ulcerative colitis. The ISIS 2302-CS22 study will examine the effects of one of two dosages of alicaforsen delivered by enema over a six-week period as compared to an active control, mesalamine enema (The probability of receiving the alicaforsen formulation is 2:1). The primary objective of this study is to evaluate the percentage reduction in DAI at Week 6.
NCT00098111 ↗	Imuran (Azathioprine) Dose-Ranging Study in Crohn's Disease	Terminated	Massachusetts General Hospital	Phase 3	2005-04-01	The purpose of this study is to identify an optimal weight based dose of azathioprine that is safe and effective in the treatment of subjects with active Crohn's disease requiring treatment with corticosteroids, and for maintaining remission in those subjects.
NCT00109473 ↗	Trial of Growth Hormone Therapy in Pediatric Crohn's Disease	Completed	Genentech, Inc.	Phase 2	2005-04-01	The purpose of this study is to determine whether taking a growth hormone (GH) drug called somatropin causes the intestine of a person with Crohn's Disease (CD) to heal faster when compared to a person with Crohn's Disease that does not receive growth hormone drug.
NCT00109473 ↗	Trial of Growth Hormone Therapy in Pediatric Crohn's Disease	Completed	Children's Hospital Medical Center, Cincinnati	Phase 2	2005-04-01	The purpose of this study is to determine whether taking a growth hormone (GH) drug called somatropin causes the intestine of a person with Crohn's Disease (CD) to heal faster when compared to a person with Crohn's Disease that does not receive growth hormone drug.
NCT00151892 ↗	Efficacy and Safety of SPD476 in Maintaining Remission in Patients With Ulcerative Colitis	Completed	Shire	Phase 3	2005-04-08	Ulcerative colitis is a disease of the large bowel (colon) and rectum in which the lining of the bowel becomes red and swollen. Over time, patients with this disease may experience acute episodes of diarrhea, rectal bleeding and abdominal pain followed by periods of time without disease symptoms. 5-ASA drugs are a standard treatment for ulcerative colitis. Mesalazine is an experimental drug designed to gradually release 5-ASA into the areas of large bowel associated with ulcerative colitis. This study will test the safety and efficacy of mesalazine in keeping ulcerative colitis in remission.
