Safety and Efficacy of AST-120 in Mild to Moderate Crohn's Patients With Fistulas

Summary

The objective of this study is to evaluate the safety and effectiveness of the experimental drug AST-120 in treating patients with mild to moderately severe Crohn's disease who have fistulas. The study will test whether or not patients receiving AST-120 experience a greater reduction in number of draining fistulas and improvement of their other Crohn's disease symptoms versus patients who receive placebo (material that does not contain any active medication).
