Phase II Study of Three Hour, Weekly Infusion of ET-743 (Yondelis) in Men With Advanced Prostate Carcinoma

This is an open-label (identity of assigned study drug will be known), 2-stage study of
ET-743 (trabectedin) in adult men with advanced metastatic prostate cancer. In the first
stage of the study, patients will be treated with weekly study drug infusions for 3 out of 4
weeks. If patients meet protocol-defined criteria for the primary endpoint of
prostate-specific antigen (PSA) response, the second stage will be initiated to also include
enrollment of patients previously treated with docetaxel. Disease response and safety will
be monitored.

- Agrees to protocol-defined use of effective contraception

Exclusion Criteria:

- Treatment with chemotherapy or radiation therapy that was terminated at least 4 weeks
before study entry

- Treatment with extensive external beam radiation therapy or radionuclide therapy
within 6 weeks of study entry (palliative radiation involving less than 20% of bone
marrow reserves must have been completed at least 4 weeks before study entry)

- Other protocol-defined serious illnesses or medical conditions
