• Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) < 2.5 x ULN or < 5 x ULN if liver metastases
• Calculated creatinine clearance > 50 mL/min
• Life expectancy of at least 3 months
• Women of childbearing potential (WOCBP) must use appropriate method(s) of contraception for 23 weeks after the last dose of investigational drug; men who are sexually active with WOCBP must use any contraceptive method(s) with a failure rate of less than 1% per year for 31 weeks after the last dose of investigational drug; women who are not of childbearing potential (i.e., who are postmenopausal or surgically sterile as well as azoospermic men) do not require contraception; should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately

• Women must not be pregnant or breastfeeding
• Ability to understand and willingness to sign a written informed consent document
• PHASE II INCLUSION CRITERIA: Patients must have cytologically or histologically confirmed ES-SCLC and must not have progressed after first line platinum-based chemotherapy regimen before randomization
• PHASE II INCLUSION CRITERIA: Patients with tumor tissue uptake during NETSPOT PET that is equal to or higher than that in normal hepatic tissue (grade >= 2) will be eligible; it is recommended that NETSPOT PET be obtained before initiation of chemotherapy, but NETSPOT PET obtained during or after completion of chemotherapy could be used for screening purpose
