- All patients must have measurable or evaluable disease defined by Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 criteria; if the patient has received prior radiation therapy one measurable lesion must be outside the irradiated field; lesions within an irradiated field will be followed as non-target lesions and considered evaluable; if the only site of measurable disease is within a previously irradiated field then 6 months must have elapsed between the completion of radiation therapy and entry on study to be considered measurable
