Phase 2 Trial of Enzastaurin in Prostate Cancer in Participants Who Have Had Hormonal and Chemotherapy
Phase 2 Trial Oral Enzastaurin in Prostate Cancer Patients Who Have Rising PSA (1) During Hormonal Manipulation and (2) After First-Line Cytotoxic Chemotherapy
The purpose is to see how quickly two different types of prostate cancer participants respond when taking enzastaurin.
Cohort 1 - asymptomatic participants with androgen-independent prostate-specific antigen (PSA)-progressive disease without clinical or radiographic evidence of metastatic disease.
Cohort 2 - participants with androgen-independent metastatic prostate cancer (documented bone or soft tissue metastases) with rising PSA, clinical, radiographic disease progression following one prior docetaxel-based regimen
