Study of Ruxolitinib (INCB018424) Administered Orally to Patients With Androgen Independent Metastatic Prostate Cancer

This study has been 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.)

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 2, Open-Label Study of INCB018424 Administered Orally to Patients With Androgen Independent Metastatic Prostate Cancer

Primary Outcome Measures:
  • 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).

Secondary Outcome Measures:
  • 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.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No

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.
