About

The purpose of the study is to determine the dose of the combination of trabectedin (Yondelis) and Doxorubicin for which neutropenia (low white blood cell counts) could be managed with filgrastim (a Granulocyte-Colony Stimulation Factor that is used to help control neutropenia) in patients with a type of cancer called soft tissue sarcoma.

Full description

This is a multicenter, open-label (identity of the assigned study treatments will be known to patients and study staff) study to determine the dose of the combination of trabectedin (Yondelis) and Doxorubicin for which the neutropenia (low white blood cell counts) is manageable with the use of filgrastim (an agent used to manage neutropenia) and associated with clinically acceptable number of side effects severe enough to continuation of treatment in patients with recurrent or persistent soft tissue sarcoma (STS, a malignant tumor that attacks the body's infrastructure of fat, muscles, nerves, joints, blood vessels, or deep skin tissues). Patients will be enrolled in the study after all study-specific entry criteria are met and informed consent is obtained. Patients will be required to attend regular clinic visits to receive study medication and have their status monitored. A detailed explanation can be provided by the study physician (Investigator) conducting this study. Doxorubicin (50 to 75 mg/m2) will be given as a 10-15 minute intravenous (i.v.) infusion on Day 1 via a central venous catheter which is a tube placed into a large vein. Trabectedin (0.9 to 1.3 mg/m2) will be given as a 3 hour i.v. infusion, immediately following the administration of doxorubicin. Dexamethasone 20 mg will be given within 1 hour before the start of each doxorubicin i.v. infusion and filgrastim will be administered according to manufacturer's instructions.

Experimental group

Description:

Doxorubicin (50 to 75 mg/m2) administered intravenously on Day 1 followed by trabectedin (0.9 to 1.3 mg/m2) administered intravenously on Day 1 every 3 weeks for up to 6 cycles. Dexamethasone 20 mg administered intravenously will be given within 1 hour before the start of doxorubicin. Patients may receive filgrastim for unmanageable neutropenia.
