Study summary

The main purpose of this study is to find out what effects (good or bad) trabectedin (ET743) has on men with advanced prostate carcinoma.

Read the detailed description
  • Treatment with trabectedin will be given once a week for three consecutive weeks with one week of no treatment. This four week period constitutes one cycle.
  • Trabectedin is given as an infusion through a central venous catheter and is administered over 3 hours.
  • On day 1 of each cycle a history, physical exam and blood tests will be performed and trabectedin will be administered.
  • On day 8 and day 15 of each cycle blood work will be performed and trabectedin will be administered.
  • Patients will continue to receive trabectedin as long as there is no disease progression or unacceptable side effects.
  • Scans (CT, MRI or bone) or x-rays may be done while the patient is on the trial at the discretion of the physician.
