Can you tell me what became of the investigational drug amn-107 for gist tumors?

Amn-107 is TASIGNA (nilotinib) Amn 107 tasigna (nilotinib) is used for CML ( chronic myeloidleukemia ) especially if resistant to Gleevec fda did not aprove for gastointestinal stromal cell tumors ( gist ).
Complicated. A phase 1 trial has been completed and reported, but a phase 2 trial comparing amn107, or nilotinib, to imatinib (gleevec), was closed early due to interim analysis showing nonsuperiority. It is being tried in combo with Gleevec in other trials. Fox chase has a trial. Nccn guidelines accept nilotinib as a treatment option but it's use is still off-label for now in gist.
