Basic Trial Information

Phase Type Status Age Sponsor Protocol IDs Phase II Biomarker/Laboratory analysis, Treatment Active 18 and over NCI NCI-07-C-0106 07-C-0106, 7678, NCT00450619

Special Category: NIH Clinical Center trial

Objectives

Primary

1. Compare the effect of samarium Sm 153 lexidronam pentasodium with or without recombinant fowlpox-TRICOM vaccine, recombinant vaccinia-TRICOM vaccine, and sargramostim (GM-CSF) on the 4-month progression-free survival of patients with androgen-insensitive, prostate cancer metastatic to the bone.

Secondary

1. Compare immunologic response and prostate-specific antigen changes in patients treated with these regimens.
2. Compare response in patients treated with these regimens.
3. Compare the toxicity of these regimens in these patients.
4. Compare progression-free survival and overall survival of patients treated with these regimens.
5. Compare the relief of bone pain in patients treated with these regimens.

Outline

This is a randomized, open-label, pilot study. Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients receive samarium Sm 153 lexidronam pentasodium (¹⁵³SM-EDTMP) IV over 1 minute on day 8. Treatment repeats every 12 weeks in the absence of disease progression or unacceptable toxicity.



• Arm II: Patients receive recombinant vaccinia-TRICOM vaccine subcutaneously (SC) on day 1. Patients also receive recombinant fowlpox-TRICOM vaccine SC on days 15 and 29 and sargramostim (GM-CSF) SC on days 1-4, 15-18, 29-32. Treatment with recombinant fowlpox-TRICOM vaccine and GM-CSF repeats every 4 weeks in the absence of disease progression or unacceptable toxicity. Patients also receive ¹⁵³SM-EDTMP as in arm I.

Patients who are HLA-A2-positive undergo apheresis for immunological studies. Blood serum is analyzed for interferon gamma-releasing T cells specific to prostate-specific antigen (PSA)-3A as measured by ELISPOT assay as well as antibodies to PSA, vaccinia, fowlpox, and antinuclear antibody titer.

Bone pain is assessed periodically.

After completion of study treatment, patients are followed periodically for up to 15 years.
