The MGTX experience: challenges in planning and executing an international, multicenter clinical trial

J Neuroimmunol. 2008 Sep 15;201-202:80-4. doi: 10.1016/j.jneuroim.2008.05.031.

Abstract

We present our experience planning and launching a multinational, NIH/NINDS funded study of thymectomy in myasthenia gravis. We highlight the additional steps required for international sites and analyze and contrast the time investment required to bring U.S. and non-U.S. sites into full regulatory compliance. Results show the mean time for non-U.S. centers to achieve regulatory approval was significantly longer (mean 13.4+/0.96 [corrected] months) than for U.S. sites (9.67+/0.74 [corrected] months; p=0.003, [corrected] t-test). The delay for non-U.S. sites was mainly attributable to Federalwide Assurance certification and State Department clearance.
