|Actual Study Completion Date :||January 2009|
Participants received ruxolitinib 25 mg orally twice daily in 12-hour intervals for 21-day cycles for as long as the study medication was tolerated and provided clinical benefit.
Ruxolitinib 25 mg tablets taken with water twice a day.

- Number of Participants With a Prostate-specific Antigen Response [ Time Frame: Assessed monthly from Baseline until the end of study (up to 8 months) ]A prostate-specific antigen (PSA) response was defined as a PSA decline from Baseline of 50% or greater, repeated on 2 occasions at least 4 weeks apart.
- Number of Participants With Adverse Events (AE) [ Time Frame: From Baseline through to the end of study (up to 8 months) ]A treatment-related AE was defined as an event with a definite, probable, or possible causality to study medication. A serious AE is an event resulting in death, hospitalization, persistent or significant disability/incapacity, or is life threatening, a congenital anomaly/birth defect or requires medical or surgical intervention to prevent 1 of the outcomes above. The intensity of an AE was graded according to the National Cancer Institute common terminology criteria for adverse events (NCI-CTCAE) version 3.0: Grade 1 (Mild); Grade 2 (Moderate); Grade 3 (Severe); Grade 4 (life-threatening).
- Time to Progression [ Time Frame: From Baseline until the end of study (up to 8 months). ]
The time from first dosing day to the date of disease progression:
- Progressive measurable disease by RECIST criteria (regardless of bone scan or prostate-specific antigen (PSA) results).
- Development of unequivocal new lesions on bone scan without clinical suspicion of a "flare" reaction.
- In patients who responded or had a decreased PSA from Baseline, a rise of 50% from PSA nadir, if the increase is ≥ 5 ng/mL or back to Baseline and confirmed by a 2nd value.
- In patients with no decrease in PSA from Baseline, a 25% rise over Baseline and ≥ 5 ng/mL confirmed by a 2nd value.
- Number of Participants With a Complete Response or Partial Response [ Time Frame: From Baseline through the end of study (up to 8 months) ]Complete Response (CR) and Partial Response (PR) defined by the Response Evaluation Criteria in Solid Tumor (RECIST) criteria. CR: Disappearance of all target and nontarget lesions. PR: At least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum longest diameter, or persistence of 1 or more nontarget lesion(s) or/and maintenance of tumor marker level above the normal limits.
