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

Academic Article


  • 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 months) than for U.S. sites (9.67 ± 0.74 months; p = 0.0175, t-test). The delay for non-U.S. sites was mainly attributable to Federalwide Assurance certification and State Department clearance. © 2008 Elsevier B.V.
