Brief summary:
The combination of ketaconazole and hydrocortisone is commonly used for the treatment of prostate cancer. The purpose of this study is to determine if the addition of a drug called dutasteride to this approved combination will make the combination more effective in treating prostate cancer.

Detailed description:
* Participants will be seen by the study physician every four weeks and have a short physical examination, blood tests and be asked to provide information about their condition. Every three months they will undergo a bone scan. If the CT scan that was obtained before the participant started the study shows evidence of cancer, they will be asked to repeat this test every three months.
* Ketaconazole will be taken orally three times a day on an empty stomach. Hydrocortisone will be taken orally in the morning and at night. Dutasteride will be taken orally once a day.
