Exisulind and Intermittent Androgen Suppression (ADT) in Biochemical Relapsed Prostate Cancer

A study doctor will meet with you and ask you about your medical history, examine you, and explain the study. We will draw some blood for tests (about 4-6 tablespoons), including Prostate-Specific Antigen (PSA). If not already obtained, you will have a bone scan and a computed tomography scan (CT scan) to establish a baseline. You will be receiving hormone suppression treatment with monthly injections of a luteinizing hormone-releasing hormone (LHRH) analog such as Lupron or Zoladex and an antiandrogen such as Eulexin or Casodex as part of your standard care for prostate cancer. About 3 months before your next "off-treatment" period, you will start 1 Exisulind pill 250 mg (2 x 125mg capsules) by mouth twice a day. It is necessary for you to start the Exisulind treatment 3 months prior to your next "off-treatment" period so that the medication can build up in your system enough to be effective. Per our standard follow-up procedures, we will ask you to have blood draws every 2 weeks for up to 12 weeks after starting Exisulind to check liver function. Thereafter you will be asked to have monthly blood draws, and return to the clinic every 3 months for a physical examination, to determine how well you are tolerating the study medication, how your cancer is responding to the treatment, and to give you more study medication. You will continue taking Exisulind during your "off-treatment" period until your PSA reaches a threshold level. PSA threshold is defined by your primary treatment. If you have had your prostate removed, the threshold is 1.0 ng/dL. If you have an intact prostate, your threshold is 4 ng/dL. Once your PSA reaches this level, you will restart your hormone suppression treatment as directed by your doctor.
