Tesetaxel in Chemotherapy-naive Patients With Progressive, Castration-resistant Prostate Cancer

Given the activity of docetaxel in patients with progressive, metastatic castration-resistant prostate cancer, this study is being undertaken to evaluate the activity of tesetaxel, an orally bioavailable taxane, in chemotherapy-naive and chemotherapy-exposed patients.

Exclusion Criteria

• History or presence of brain metastasis or leptomeningeal disease
• Operable cancer
• Uncontrolled diarrhea

• Known malabsorptive disorder
• Currently active second malignancy other than non-melanoma skin cancers
• Human immunodeficiency virus (HIV) infection based on history of positive serology
• Significant medical disease other than cancer
• Presence of neuropathy > Grade 2 (National Cancer Institute Common Toxicity Criteria [NCI CTC]; v4.0)
• Need for other anticancer treatment
• Need to continue any regularly-taken medication that is a potent inhibitor or inducer of the CYP3A pathway or P-glycoprotein activity
