Shortly after IRB approval was obtained at Washington University, the PI, Dr. Ronald Lehman, transferred to Columbia University. No other study-related procedures have taken place, as the transfer of the grant continues to be processed. Two issues have slowed the completion of this transfer. First, Columbia University does not encounter patients that meet inclusion criteria at nearly the same volume as the original institution. Thus, new sub-sites needed to be added to ensure that recruitment would follow the time course described in the statement of work. Second, over the course of the transfer, it was discovered that one of the sub-sites originally listed had applied for a grant in direct competition to this one. Subsequently, that site was removed from the grant and are placement was needed to cover the associated loss in anticipated patient enrollment. We apologize for this delay, and have every anticipation that the transfer application will be submitted shortly and successfully.
