Patients who received prior platinum-containing adjuvant, neoadjuvant, or definitive chemoradiation for locally advanced disease are eligible, provided that progression has occurred > 6 months from last therapy • Prior radiotherapy and surgery are allowed if completed 4 weeks prior to start of treatment and patient recovered from toxic effects or associated adverse events • Adequate blood count, liver-enzymes, and renal function  ◦ Hemoglobin ≥ 9.0 g/dl  ◦ Absolute neutrophil count (ANC) ≥ 1.5 × 109/L (> 100 per mm3)  ◦ Platelet count ≥ 100 × 109/L (> 100,00 per mm3)  ◦ Serum bilirubin ≤ 1.5 × ULN. This will not apply to subjects with confirmed Gilbert’s syndrome (persistent or recurrent hyperbilirubinemia that is predominantly unconjugated in the absence of hemolysis or hepatic pathology), who will be allowed only in consultation with their physician  ◦ AST (SGOT)/ALT (SGPT) ≤ 2.5 × institutional upper limit of normal unless liver metastases are present, in which case it must be ≤ 5 × ULN  ◦ Serum creatinine CL > 40 mL/min by the Cockcroft-Gault formula (Cockcroft and Gault 1976) or by 24-h urine collection for determination of creatinine clearance  ◦ Subject is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits, examinations including follow-up, and appropriate contraception

Exclusion criteria
