At least one measurable lesion according to RECIST 1.1 criteria, defined as a lesion with a longest diameter =10 mm on CT scan or MRI (excluding lymph nodes) or a short diameter =15 mm for lymph nodes. Lesions located in previously irradiated or otherwise locally treated areas are generally not considered measurable unless there is documented disease progression; 8.
