A Phase 2 Study to Investigate the Clinical Activity of IPI-504 in Patients With Hormone-resistant Prostate Cancer

Not Recruiting

Trial ID: NCT00564928


To determine: - Anti-tumor activity of IPI-504 in 2 groups of subjects with hormone resistant prostate cancer. - Group A - subjects who have not previously received chemotherapy - Group B - sujects who have received prior chemotherapy or could not tolerate chemotherapy. - Clinical response will be determined by PSA and radiological response
