PURPOSE: Development of new therapies for previously treated small-cell lung cancer (SCLC) is a major unmet need. Here, we describe a randomized, phase II trial of weekly topotecan with or without ziv-aflibercept (VEGF-trap) in this clinical setting. PATIENTS AND METHODS: Patients with previously treated SCLC (one line of platinum-based chemotherapy), performance status of 0 to 1, adequate organ function, treated brain metastases, and no recent vascular events or bleeding diatheses were eligible. Eligible patients were stratified as platinum-sensitive or platinum-refractory and randomly assigned to receive weekly topotecan 4 mg/m(2) intravenously (IV) with or without ziv-aflibercept 6 mg/kg IV every 21 days. Progression-free survival (PFS) at 3 months was the primary end point. RESULTS: In 189 randomly assigned patients, treatment arms were well balanced with regard to clinical characteristics. The 3-month PFS was significantly improved with the addition of ziv-aflibercept in patients who had platinum-refractory disease (27% v 10%; P = .02) but not in patients with platinum-sensitive disease (24% v 15%; P = .22). Although response rate was low, disease control rate was higher with combination therapy than with topotecan alone in patients who had platinum-sensitive disease (37% v 18%; P = .05) and in those who had platinum-refractory disease (25% v 15%; P = .14). Overall survival (OS) was not significantly improved in either strata. Grades 3 to 5 toxicities were more common with the addition of ziv-aflibercept. CONCLUSION: Ziv-aflibercept improved the 3-month PFS in patients who had platinum-refractory SCLC, but its addition increased toxicity. OS was similar with combined ziv-aflibercept and topotecan compared with topotecan in both strata.
