The purpose of this study is to test the safety and effectiveness of an investigational chemotherapy agent in patients with types of advanced cancer referred to as liposarcoma or leiomyosarcoma.
This is an open-label (patients will know the names of the study drugs they receive), randomized (patients will be assigned by chance to receive 1 of 2 treatment schedules with trabectidin) study designed to examine the the survival, safety, and pharmacokinetics (blood levels) trabectedin when administered to patients with 2 types of cancer (Liposarcoma or Leiomyosarcoma) who have received treatment with other anti-cancer therapy (Anthracycline and/or Ifosfamide). Trabectedin (also referred to as Yondelis) is a drug being developed to treat patients with cancer. Yondelis will be administered intravenously (i.v.) via a central catheter (tube) into a central vein once a week (0.58 mg/m2 as a 3-hour infusion on Days 1, 8, and 15 of each 28-day treatment cycle) or once every 3 weeks (1.5 mg/m2 administered as a 24-hour infusion on Day 1 of every 21-day treatment cycle) until disease progression. Patients in each arm will be pretreated with 20 mg of dexamethasone i.v. 30 minutes prior to each infusion.

Time to Progression- Independent Review
Time to Progression was defined as time between randomization and the first documentation of disease progression or death due to progressive disease.
Time frame: From randomization to the first documentation of disease progression or death due to progressive disease, whichever occurs first, assessed up to 5 years
Percentage of Participants Objective Response - Independent Review
Percentage of participants with objective response based on assessment of confirmed complete response (CR) or confirmed partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST). Confirmed CR defined as disappearance of all target lesions. Confirmed PR defined as greater than or equal to 30 percent decrease in sum of the longest dimensions (LD) of the target lesions taking as a reference the baseline sum LD according to RECIST. Confirmed responses are those that persist on repeat imaging study greater than or equal to 4 weeks after initial documentation of response.
Time frame: From randomization to the first documentation of disease progression or death due to progressive disease, whichever occurs first, assessed up to 5 years
Duration of Response - Independent Review
Duration of response based on assessment of confirmed CR or confirmed PR according to RECIST. Confirmed CR defined as disappearance of all target lesions. Confirmed PR defined as greater than or equal to 30 percent decrease in sum of the LD of the target lesions taking as a reference the baseline sum LD according to RECIST. Confirmed responses are those that persist on repeat imaging study greater than or equal to 4 weeks after initial documentation of response. Kaplan-Meier estimation of response duration was used to account censored participants with ongoing response.
Time frame: From randomization to the first documentation of disease progression or death due to progressive disease, whichever occurs first, assessed up to 5 years
