Brief Summary:

as second-line treatment in metastatic prostate cancer, the present study will investigate the efficacy of sunitinib (SUTENT) given orally at a dose of 37.5 mg continuously, for 6 cycles of 6 consecutive weeks .Patients who are still responders after 6 cycles will be treated until disease progression, pain progression, unacceptable toxicity or death due to any cause.

Dose increase or reduction of 12.5 mg increments and change of schedule is recommended based on individual safety and tolerability.

Follow-up for up to 1 year from the last dose of sunitinib.

Condition or disease Intervention/treatment Phase
Prostatic Neoplasms Neoplasms, Hormone-Dependent Tumor Markers, Biological Survival Rate Disease-Free Survival Drug: sunitinib Phase 2

Detailed Description:
  • Antitumor efficacy of sunitinib will be assessed as follows:

    • PSA response rate and PSA progression according Working Group Criteria,
    • Variation of PSA doubling time (PSADT) before and after initiation of the treatment,
    • Objective response rate (ORR) according to RECIST criteria,
    • Clinical benefit,
    • Overall survival (OS).
  • Pharmacokinetic endpoints will include sunitinib and its metabolite, SU012662, plasma levels and estimation of the population pharmacokinetic parameters as well as the inter-individual variability of these parameters, for a subgroup of 30 patients.
  • The biological effects of sunitinib in patients with metastatic prostate carcinoma will be evaluated by measurements of the different biological markers that could be modulated by this antiangiogenic therapeutic, and could then predict and monitor disease progression and response to treatment:

    • Bone tumor markers: bone resorption markers (uCTX, uCTX, ICTP, CTX-MMP and TRACP-5b), bone formation markers (OC, PINP and BALP), osteoclastogenesis markers (OPG and RANKL) and parameters as calcium, phosphate, creatinine, albumin, PTH and 25(OH)D.
    • Angiogenesis markers: bFGF, SDF-1, VEGF-A, VEGFR1 and VEGFR2, CECs and CEPs, endothelial and platelet microparticles.

Arm Intervention/treatment
Experimental: drug
Drug: sunitinib
37.5 mg orally once daily, continuously, for 6 cycles of 6 consecutive weeks.Dose increase or reduction of 12.5 mg increments and change of schedule is recommended based on individual safety and tolerability.

Primary Outcome Measures :
  1. progression-free survival (PFS) defined as the time from start of study treatment to first documentation of objective progressive disease, pain progression or to death on-study due to any cause. [ Time Frame: 18 months ]

Secondary Outcome Measures :
  1. Incidence and intensity of Adverse Events (NCI CTCAE version 3.0). [ Time Frame: 9 months ]

  • Life expectancy of at least 3 months
  • Resolution of all acute toxic effects of any prior local treatment to NCI CTCAE grade 1
  • Patients must have adequate organ functions defined
  • Willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures
  • Patient covered by the National Health System

Exclusion Criteria:

  • Prior treatment with sunitinib or other antiangiogenic agent

Low dose of warfarin for deep vein thrombosis prophylaxis is permitted (up to 2 mg/day) and low molecular weight heparin is allowed
  • Any medical condition that might interfere with oral medication absorption
  • Known or suspected brain metastasis, or carcinomatous meningitis, or spinal cord compression
