             metastatic disease, one of which must be a platinum-doublet therapy.

          5. Must have disease progression or recurrence documented by radiographic assessment
             following treatment after last chemotherapy or chemoradiation regimen (completed

          6. Must have available recent (before treatment start) or archival tumor specimen.

          7. Must have measurable disease for Part A, measurable disease or non-measurable disease

          3. Prior EGFR-targeted regimen, anti-HER2, anti-HER3, or anti-HER4 therapy

          4. History of other malignancies, except adequately treated non-melanoma skin cancer,
             curatively treated in-situ disease, or other solid tumors curatively treated with no

         12. Treatment with anticancer therapy, antibody-based therapy, retinoid therapy, or
             hormonal therapy within 4 weeks before study drug treatment

         13. Therapeutic radiation therapy or major surgery within 4 weeks before study drug
             treatment; or palliative radiation within 2 weeks before study drug treatment

         14. Participation in clinical drug trials within 4 weeks

         15. Uncontrolled infection requiring IV antibiotics, antivirals, or antifungals, known
