Study of Samarium Sm-153 Lexidronam Combined With Docetaxel for Patients With Prostate Cancer
Phase I/II Trial of Samarium Sm-153 Lexidronam Combined With Docetaxel for Patients With Androgen-Independent Prostate Cancer
The purpose of this study is to investigate the safety, tolerability and anti-tumor effects of treatment with samarium Sm-153 lexidronam in combination with docetaxel in patients with castrate metastatic prostate cancer.
The principal objective of this trial is to evaluate the safety, feasibility, and anti-tumor effects of a novel bone-targeted regimen consisting of Samarium Sm-153 lexidronam combined with docetaxel and prednisone. This present study design permits evaluation of the clinical activity of combining two distinct agents that have shown benefit for the treatment of patients with advanced androgen-independent prostate cancer and bone metastases. It enables assessment of potential synergistic interactions between a cytotoxic chemotherapy agent and a bone-targeting radioisotope agent in the setting of a bone-targeted therapy.

  • Patients undergoing prior bisphosphonate treatments are eligible.
  • Patients who have received one prior treatment with 153Sm lexidronam or 89Sr are eligible provided it is at least 12 weeks from treatment with 153Sm lexidronam or 24 weeks from treatment with 89Sr.
  • Life expectancy of at least 12 weeks (based on co-morbidity).
  • KPS>60.

    • Hemoglobin (HGB) ≥ 10 mg/dl;
    • Bilirubin ≤ 2.0 mg/dl;
    • ALT/AST≤ 3 times the upper limit of normal;
    • Serum creatinine ≤ 2.0 mg/dl.

  • Patients who have received more than one course of external beam radiation therapy directed at bone lesions.
  • Clinically significant cardiac disease (New York Heart Association Class III/IV).
