ASA404 in Combination With Carboplatin/Paclitaxel/Cetuximab in Treating Patients With Refractory Solid Tumors

Study Overview
=================
Brief Summary
-----------------
This phase I trial is studying the side effects and best dose of an investigational drug called DMXAA (5-6-dimethylxanthenone-4-acetic acid) or ASA404 when given together with carboplatin, paclitaxel and cetuximab to treat patients with refractory solid tumors.

Detailed Description
-----------------
Phase I 3+3 dose escalation design in patients with solid tumors who have been previously treated with chemotherapy or for whom no standard treatment options exist. Carboplatin, paclitaxel and cetuximab will be administered in standard doses. The dose of ASA404 will be escalated under predefined levels. One treatment cycle constitutes 3 weeks. A minimum of 3 patients will be entered at each treatment level, to be expanded to 6 subjects if dose limiting toxicities (DLT) are observed. If no more than one in six patients has DLT, additional patients will be enrolled at a higher dose. Once a maximum tolerated dose (MTD) has been established, the tolerability of this dose will be tested in a total of 12 patients. The anticipated sample size is 18-24 patients. Carboplatin and paclitaxel are chosen as the chemotherapy back bone since they are commonly used in combination in multiple tumors. Cetuximab has been chosen as the EGFR inhibitor because the combination of platinum based therapy with cetuximab is effective in lung and head and neck cancers. In addition the safety and activity of carboplatin/paclitaxel with ASA 404 has already been demonstrated. A weekly schedule of ASA is chosen because 1) the safety of the weekly schedule has been tested 2) preclinical studies confirm enhanced activity with frequent administration 3) provides an opportunity to evaluate the safety and pharmacokinetics of ASA 404 with weekly cetuximab.
