Brief Summary:
This study will test whether a new experimental drug called STA-5326 mesylate will decrease inflammatory chemicals called cytokines in patients with Crohns disease The drug has prevented gut inflammation in mice and rats and has improved symptoms in humans with active Crohns disease
Patients with Crohns 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 Crohns 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

Detailed Description:
The purpose of this study is to measure the mucosal immunological effects and peripheral blood effects of the oral IL-1223 inhibitor STA-5326 mesylate in subjects with active Crohns disease CD Crohns disease is a chronic relapsing inflammatory condition of the small and large bowel associated with excessive Th1 cytokine production Since IL-12 is a key cytokine driving the Th1 response novel therapies targeting IL-12 have been successful in treating CD in animal models and in humans Data from humans and from animal models further suggest that both IL-12 and IL-23 may have a role in this active gut inflammation STA-5326 mesylate is an oral drug that suppresses IL-12p40 production a subunit shared by IL-12 and IL-23 in vitro and has apparent safety and clinical activity in a recent open-label trial of treatment for CD
This protocol will enroll and randomize 12 subjects with moderate to severe active CD CD Activity Index CDAI 220 to 450 inclusive for 4 weeks of daily study drug treatment 9 subjects will receive 100 mg STA-5326 mesylate and 3 will receive placebo Subjects will be evaluated for safety that will include monitoring of adverse events and concomitant medications clinical laboratory testing electrocardiogram ECG tracings and physical examinations including vital signs Efficacy assessments will include the CDAI the Simple Endoscopic Score for CD SES-CD results from the Inflammatory Bowel Disease Questionnaire IBDQ and changes from Baseline for plasma C reactive protein CRP measured by high sensitivity assay In addition immunologic effects lymphocyte phenotyping cytokine secretion from peripheral blood and lamina propria mononuclear cells LPMCs will be assessed Descriptive statistics n mean median standard deviation minimum and maximum range will be used to summarize data for each treatment group
