a phase 1b study with volociximab in combination with carboplatin and paclitaxel in first-line, advanced non-small cell lung cancer (nsclc)

Conditions: Non-small Cell Lung Cancer

Summary: the primary purpose of this study is to examine the safety of volociximab in combination with a standard treatment of carboplatin and paclitaxel in subjects previously untreated with chemotherapy for advanced stage (iiib/iv) non-small cell lung cancer (nsclc).

this phase 1b, multicenter, open-label, dose-escalation study will evaluate the safety and pharmacokinetics (pk) of volociximab in combination with carboplatin and paclitaxel (c/p) as first-line treatment in subjects with stage iiib or iv non-small cell lung cancer (nsclc). volociximab doses of 10, 20, and 30 mg/kg (or 15 mg/kg if 20 mg/kg is not tolerable) with carboplatin/paclitaxel chemotherapy will be tested for determining the maximum tolerated dose (mtd). subjects will be dosed once very 3 weeks for up to 6 cycles. volociximab is a high-affinity, chimeric monoclonal antibody that specifically binds to α5β1 integrin, a cell-surface receptor for fibronectin. volociximab blocks the binding of α5β1 to fibronectin, thereby inhibiting a pivotal interaction required for angiogenesis. more than 170 subjects with various solid tumor types have received volociximab in phase 1 and phase 2 single and combination studies. at the doses tested, there has not been a dose limiting toxicity (dlt) or a maximum tolerated dose (mtd) defined.
