Drug-Drug Interaction Study Between Colchicine and Cyclosporine

• Status: Completed
• Trial end date: 2008-09-01
• Target enrollment: 0
• Participant gender: All

Summary

Colchicine is a substrate for both cytochrome P450 3A4 (CYP3A4) and P-glycoprotein (P-gp). Cyclosporine is a potent inhibitor of both CYP3A4 and P-gp. This study will evaluate the effect of single-dose cyclosporine on the pharmacokinetic profile of a single 0.6 mg dose of colchicine. A secondary objective is to evaluate the safety and tolerability of this regimen in healthy volunteers. All study subjects will be monitored for adverse events throughout the study period
