Study Overview
Brief Summary
This is an open label phase 2 study using metronomic doses of trabectedin, gemcitabine and dacarbazine given intravenously.
Detailed Description
This is an open label phase 2 study using metronomic doses of trabectedin, gemcitabine and dacarbazine given intravenously.
A total of 80 patients will receive trabectedin 0.5 mg/m2 as 24 hour continuous intravenous infusion (CIV) on D1 and D8, gemcitabine 200 mg/m2 i.v. on D1 and D8, and dacarbazine 200 mg/m2 i.v. on D1 and D8 (see product information; www.accessdata.fda.gov). Treatment cycles are given every 3 weeks. Patients in this study may continue treatment until significant disease progression or unacceptable toxicity occurs up to one year of therapy. Patients who withdraw or do not complete the first 2 treatment cycles and first follow up CT scan/MRI will be replaced.
