Presence of known central nervous system metastases, but the following patients will be allowed: a) Asymptomatic brain metastases; b) Clinically stable (no radiographic progression within 4 weeks before apheresis and return of any neurologic symptoms to baseline), and with no need for corticosteroids or other treatment for brain metastases for ≥ 4 weeks.
Patients with clinically significant systemic disease (such as: severe active infection or significant cardiac, pulmonary, hepatic, nervous system, or other organ dysfunction) that evaluated by the investigator would impair the patients' ability to tolerate the treatments used in this study or significantly increase the risk of complications.
