   • Hepatic: bilirubin ≤1.5 x ULN (upper limit normal), AP, ALT, AST ≤ 1.5 x ULN. AP, ALT, and AST ≤5 x ULN is acceptable if the liver has tumor involvement.
   • Renal: calculated creatinine clearance ≥ 40 ml/min based on the Cockcroft-Gault formula.
7. Male and female patients with reproductive potential must use an approved contraceptive method, if appropriate. Female patients with childbearing potential must have a negative serum pregnancy test within 7 days prior to study enrollment.

Exclusion Criteria:

1. Pregnant or lactating women.
2. Patients with medical risks because of non-malignant disease as well as those with active uncontrolled infection.
3. Documented brain metastases unless the patient has completed local therapy for central nervous system metastases at least 4 weeks before enrollment and has been off corticosteroids for at least two weeks before enrollment. Prophylactic irradiation at least 4 weeks prior to enrollment is accepted.
4. Maintenance treatment with erlotinib or other TKI (Tyrosine Kinase Inhibitor), or docetaxel. Maintenance treatment with pemetrexed is allowed. Previous treatment with an EGFR-TKI or docetaxel within 6 months prior to enrollment.
