Brief Summary:
  • There are nearly 30,000 deaths per year in the United States from prostate cancer, making this a large and important target patient population for new cancer treatments.
  • SU011248 is an exciting, new, experimental drug that inhibits a number of proteins, or more specifically receptor tyrosine kinases, in tumor cells. These proteins are active in cellular pathways that are important for development and growth of a variety of different cancers. The targets of SU011248 include the receptors for vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF), and others. By blocking the VEGF and PDGF pathways, SU011248 can induce death of the blood vessels that nourish the cancer cells and death of the cancer cells themselves.
  • SU011248 has demonstrated significant anti-tumor activity in renal cell carcinoma, gastrointestinal stromal tumors, and other cancers. Its effect against prostate cancer has not been studied to date.
  • This study is directed at two populations of men with advanced prostate cancer:

    1. Men with advanced prostate cancer who have a rising PSA despite hormone therapy, but have not yet received any chemotherapy.
    2. Men with metastatic prostate cancer who have received prior chemotherapy (with a docetaxel-based regimen) and have increasing disease following chemotherapy.
  • Men in this study will receive SU011248 on a six-week repeating schedule, with four weeks of daily treatment followed by a two-week rest. The goals of the study are:

    1. to determine whether SU011248 is an important therapeutic agent in men with advanced prostate cancer, and
    2. to identify predictive markers of anti-cancer activity within individual subjects that would allow selective treatment of appropriate subjects in the future.

MedlinePlus related topics: Prostate Cancer

Arm Intervention/treatment
Experimental: 1
Drug: Sunitinib
Sunitinib 50 mg daily, 4/2 schedule
Other Name: Sutent

Primary Outcome Measures :
  1. The Number of Men With Advanced Prostate Cancer Treated With Sunitinib Who Have a Prostate Specific Antigen (PSA) Response [ Time Frame: were followed until disease progression, an average of 12 weeks ]
    Prostate specific antigen (PSA) responses, defined as the number of men who exhibit PSA decline of at least 50% that is confirmed by a second PSA value 4 or more weeks later (PSA Working Group I Criteria)

Secondary Outcome Measures :
  1. Objective Responses, Defined as the Number of Participants With Complete or Partial Response [ Time Frame: Participants were followed until the time of disease progression, an average of 12 weeks ]
    The response rate is defined by Response Evaluation Criteria in Solid Tumors Criteria (RECIST v1.0) for target lesions as assessed by radiographic evaluation. Complete response(CR): disappearance of all target lesions; Partial response(PR): >=30% decrease in the sum of the longest diameter of target lesions; Overall response = CR + PR.

  • Life expectancy of > 12 weeks
  • Resolution of all acute toxic effects of prior chemotherapy, radiotherapy or surgical procedure to National Cancer Institute Common Toxicity Criteria Adverse Event (NCI CTCAE) grade <1
  • Surgical or ongoing chemical castration
  • Androgen-independent disease, defined as progressive disease despite surgical or ongoing chemical castration. See section 8.2.3 for definition of progressive disease.
  • Eastern Cooperative Oncology Group performance status of 0, 1 or 2
  • Adequate bone marrow reserve:

    • Neutrophil count > 1,500/ul
    • Platelet count > 75,000/ul
  • Adequate hepatic function:

    • Serum bilirubin < 1.5 x upper limit of normal
    • Asparate aminotransferase and alanine aminotransferase < 2.5 x upper limit of normal

  • Prostate Specific Antigen (PSA) > 5.0 ng/mL, based on PSA Working Group Criteria
  • Willingness and ability to comply with scheduled visits, treatment plans, laboratory tests and other study procedures

For Group A only:

· No prior treatment for prostate cancer with cytotoxic chemotherapy

For Group B only:

  • Radiographic evidence of metastatic prostate cancer
  • One prior docetaxel-based chemotherapy regimen, minimum of two cycles
  • Disease progression during treatment with docetaxel, or within 60 days of receiving docetaxel

Exclusion Criteria:

  • Small cell carcinoma of the prostate
  • Treatment with extensive external beam radiation therapy or radionuclide therapy within six weeks of study entry. Palliative radiation involving less than 20% of bone marrow reserves must have been completed within four weeks of entry.
  • Any of the following within the prior 6 months: unstable angina, myocardial infarction, symptomatic congestive heart failure or cerebrovascular accident
  • Receipt of any investigational anti-cancer agent within 4 weeks of the study
  • NCI CTCAE grade 3 hemorrhage < 4 weeks of starting study treatment
  • Uncontrolled hypertension
  • Prolongation of the QTc interval to > 450 msec
  • Other serious acute or chronic medical or psychiatric condition that may increase the risk associated with study participation, and in the judgment of the investigator would make the subject inappropriate for entry into this study.
