          5. Adequate hepatic and renal function:

               -  AST and ALT ≤2.5 x ULN for subjects without liver metastases and ≤3.5 x ULN for
                  subjects with liver metastases

               -  Bilirubin ≤1.5 x ULN (unless bilirubin rise is due to Gilbert's syndrome or of
                  non-hepatic origin)

        Exclusion Criteria:

          1. Mixed small cell and NSCLC histology

          2. A history of CNS involvement except as follows: Subjects with previously treated CNS
             metastases that are adequately treated with whole brain radiotherapy, that are
             neurologically stable, and do not require corticosteroids for symptomatic management
             for at least 14 days prior to first dose of study drug. There must be no clear
             evidence of radiographically active disease for at least 90 days prior to enrollment.
