Study of STA-5326 Mesylate in Patients With Moderate to Severe Crohn's Disease

• Status: Completed
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

STA-5326 is an oral experimental drug that has been shown to block the release of interleukin-12 from peripheral blood mononuclear cells. Given this activity on the immune system, STA-5326 mesylate is a potential treatment for various autoimmune diseases, such as Crohn's disease, that are mediated by the inappropriate expression of Th1 cytokines.

This study is evaluating the use of STA-5326 mesylate in patients with moderate to severe, active Crohn's disease. Study visits include a screening visit, 4 treatment period visits over 4 weeks and a follow-up visit that will occur 7 days following the end of treatment. Subjects may continue treatment for an additional 4 weeks of open label STA-5326 mesylate administration that includes an additional 2 treatment period visits. Subjects will undergo a colonoscopy with biopsy collection at baseline, at the end of the 4 week blinded phase and at the end of the 4 week open label phase.
