Inclusion Criteria:

3. Any persisting toxicities that were deemed to be clinically significant from the previous therapy
4. Received more than 1 prior chemotherapy regimen for advanced disease (not including prior adjuvant therapy). Patients could have received prior epidermal growth factor receptor tyrosine kinase inhibitors
5. Unwilling or unable to take folic acid and vitamin B12 supplementation
6. Active brain metastases (stable for <28 days, symptomatic, or requiring concurrent steroids). Patients who had received prior whole brain irradiation and whose brain metastases were stable according to the criteria above were not excluded

12. Total bilirubin >1.5 mg/dL (26 μmol/L), alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) ≥2.5 x the upper limit of normal (ULN), except in cases of known liver metastasis where a maximum 5 x ULN was acceptable
13. Serum creatinine level >1.5 mg/dL and or creatinine clearance <45 mL/min
14. Sexually active and unwilling to use a medically acceptable method of contraception
