Who can join

Age: 18 and older. Sex: male. Healthy volunteers: not accepted.

You may qualify if…

• Male participants 18 years or older
• Voluntary written consent must be given before performance of any study-related procedure not part of standard medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care
• Histologically or cytologically confirmed diagnosis of prostate adenocarcinoma
• Prior surgical castration or concurrent use of an agent for medical castration [e.g. Gonadotropin-releasing hormone (GnRH) analogue]
• Prostate-Specific Antigen (PSA) ≥ 2 ng/mL at screening
• Progressive disease based on PSA and/or radiographic criteria

You may not qualify if…

• Prior therapy with orteronel, ketoconazole, aminoglutethimide, or abiraterone.
• Known hypersensitivity to compounds related to orteronel, orteronel excipients, prednisone (or commercially available equivalent), or GnRH analogue.
• All antiandrogen therapy (including bicalutamide) is excluded within 4 weeks before the first dose of study drug. Any other therapies for prostate cancer, other than GnRH analogue therapy, such as progesterone, medroxyprogesterone, progestins (megesterol), or 5- alpha reductase inhibitors (e.g., finasteride or dutasteride), must be discontinued 2 weeks before the first dose of study drug.
• Continuous daily use of oral prednisone (or commercially available equivalent), oral dexamethasone, or other systemic corticosteroids for more than 2 weeks within the 3 months before screening (inhaled, nasal, and local steroids [e.g., joint injection] are allowed).
• Prior chemotherapy for prostate cancer, with the exception of neoadjuvant/adjuvant therapy as part of initial primary treatment for local disease that was completed 2 or more years before screening.
• Please note that there are additional inclusion and exclusion criteria. The study center will determine if you meet all of the criteria.
• Site personnel will explain the trial in detail and answer any question you may have if you do qualify for the study. You can then decide whether or not you wish to participate. If you do not qualify for the trial, site personnel will explain the reasons.
