•Age : older than 18 years at Visit 1
•Histologically confirmed diagnosis of GIST that is unresectable and/or metastatic
and therefore not amenable to surgery or combined modality with curative intent
prior to or at Visit 1
•Radiological confirmation of disease progression (CT scan or MRI) during imatinib
therapy
•Radiological confirmation of disease progression (CT scan or MRI) during sunitinib
therapy. For those patients who were intolerant to sunitinib, intolerance (at any
dose and/or duration), is defined as patients who did not progress on sunitinib and
have discontinued sunitinib therapy due to any = Grade 2 adverse events that
persist in spite of optimal supportive care.
•At least one measurable site of disease on CT/MRI scan at Visit 1, as defined by
RECISTcriteria (see Post Text Suppl 3 for details)
•WHO Performance Status of 0, 1 or 2 at Visit 1 and 2
•Patients must have normal organ, electrolyte, and marrow function at Visit 1 and
Visit 2
•Ability to understand and willingness to sign a written informed consent
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range
•Prior treatment with nilotinib
•Documented intolerance or history of allergy to imatinib
•Unable to tolerate imatinib run-in of 7 days minimum
•Treatment with any cytotoxic and/or investigational cytotoxic drug = 4 weeks (6
weeks for nitrosurea or mitomycin C) prior to Visit 1 with the exception of imatinib
and sunitinib targeted therapy
•Prior or concomitant malignancies (with a relapse in the last 5 years or receiving
active treatment) other than GIST with the exception of previous or concomitant
basal cell skin cancer or previous cervical carcinoma in situ
•Impaired cardiac function at Visit 1or 2
•Use of therapeutic coumarin derivatives
•Patients who are currently receiving treatment with medications that have the
potential to prolong the QT interval
•Patients who have undergone major surgery = 2 weeks prior to Visit 1 or who
have not recovered from side effects of such therapy
Patients who have received wide field radiotherapy = 4 weeks or limited field
radiation for palliation < 2 weeks prior to Visit 1 or who have not recovered from
side effects of such therapy
