Official title

Evaluation of the Effect of Exisulind on the Duration of the "Off-Treatment" Interval on Patients With Biochemical Relapse of Prostate Cancer Who Are Treated With Intermittent Androgen Suppression (ADT)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this research study is to determine if an investigational drug called Exisulind will extend the "off-treatment" period of patients receiving Intermittent Androgen Suppression (ADT). There is evidence suggesting that alternating between periods of treatment and no treatment with androgen suppressants may delay the time to develop androgen-insensitive progression and improve overall quality of life. During intermittent androgen suppression (IAS) treatments, men receive a luteinizing hormone-releasing hormone (LHRH) agonist and antiandrogen for a fixed period of time (approximately 9 months) and then enter an off-treatment period, whose length will vary, depending on the rate of rise in the patient's Prostate-Specific Antigen (PSA). Once the PSA reaches an established threshold (1 ng/mL in men who have had a prostatectomy or 4 ng/ml in men with an intact prostate), androgen suppression will be re-initiated for another 9 months. These cycles of on-treatment/off-treatment will be repeated until patient no longer responds to the androgen suppression and it is clear that their cancer is progressing. It has been observed that off-treatment periods tend to become shorter with each successive cycle of androgen suppression, presumably due to the emergence of androgen-independent clones. This study proposes to look at exisulind, a pro-apoptotic drug, which may extend the off-treatment period in patients receiving IAS.
