Georgetown University have recently issued a press release announcing the start of their "PD Nilotinib" Phase II trial.
As far as I can see, the press release contains no new information from what we already have in this thread. However, some may find the information in the press release to be in a more-readable form than that in the "trial record" on the Clinical Trials website.
