The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
ClinicalTrials.gov Identifier: NCT00638378
Recruitment Status : Terminated (According to the protocol, the sponsor terminated the study after it was determined that less than 2 of the first 22 patients showed a PSA50 response.)

Arm Intervention/treatment
Experimental: Ruxolitinib
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.
Drug: Ruxolitinib
Ruxolitinib 25 mg tablets taken with water twice a day.
Other Name: INCB018424



Primary Outcome Measures :
  1. 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.

  2. 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).


Secondary Outcome Measures :
  1. 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.

  2. 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.

Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Diagnosed with radiographically-documented metastatic prostate cancer that has progressed while receiving androgen-suppressive therapy in the form of a bilateral orchiectomy or Gonadotropin-Releasing Hormone (GnRH) agonist (eg, leuprolide, goserelin).
  • Patients must demonstrate evidence of progressive disease based on 1 of the following criteria: 1) Progressive measurable disease, or 2) Progressive rise in prostate-specific antigen (PSA) level (2 consecutive rises from a prior reference level), or 3) Development of new lesions on bone scan.
  • If receiving a GnRH agonist as primary hormonal therapy, the serum testosterone level must be ≤ 50 ng/mL.
  • Must have received and progressed during or following 1 prior chemotherapy regimen for metastatic disease (not including an anti-androgen or ketoconazole); or, must have discontinued prior systemic therapy because of poor tolerance or other adverse effects; or, must have refused chemotherapy treatment. Patients having undergone more than 1 prior chemotherapy regimen may be admitted at the discretion of the sponsor.
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2.
  • Baseline serum PSA level of ≥ 10 ng/mL

Exclusion Criteria:

  • Received any anti-cancer medications in the 30 days before receiving their first dose of study medication except for GnRH agonists and bisphosphonates.
  • Any unresolved toxicity greater than or equal to Grade 2 from previous anti-cancer therapy, except for stable chronic toxicities not expected to resolve, such as peripheral neurotoxicity.
