A Study of Intravenous XMT-1001 in Patients With Advanced Solid Tumors

Summary

This amended expansion phase of the protocol is to further the experience at a dose level of 150 mg CPT eq/m2 in patients with Stage IV non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) and to test for preliminary anti-tumor activity in these tumor types. The MTD was initially defined as 113 mg CPT equivalents(eq)/m2 in the dose escalation part of the study. However, in the initial expansion phase (Protocol Amendment 11), 11 patients (10 NSCLC patients and 1 gastric cancer patients) were dosed at 113 mg CPT eq/m2 and less bone marrow toxicity was observed as compared to more heavily pre-treated patients in the dose escalation part of the study. Therefore, this amended expansion phase will investigate the safety and anti-tumor effects of a dose of 150 mg CPT eq/m2. The study will also determine: * The safety and tolerability of XMT-1001 at 150 mg CPT eq/m2 * The pharmacokinetics (PK) of XMT-1001 (how XMT-1001 behaves in the body) in patients Stage IV non-small cell lung carcinoma (NSCLC) and small cell lung cancer * Evidence of XMT-1001 anti-tumor activity at 150 mg CPT eq/m2
