This randomized pilot phase I trial studies how well sargramostim after cryotherapy works in treating patients with prostate cancer. Biological therapies, such as sargramostim, use substances made from living organisms that may stimulate the immune system in different ways and stop tumor cells from growing. Cryosurgery, also known as cryotherapy, kills tumor cells by freezing them. Giving sargramostim after cryotherapy may work better in treating prostate cancer.

Clinical Details

Official title: The Immuno-Response to Primary Cryotherapy for the Treatment of Prostate Cancer

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome:

Changes in B cell response identified by Serametrix assay

Change in T cell responses identified by Intracellular cytokine assay and enzyme-linked immunospot

Secondary outcome: PSA levels in serum samples

Detailed description: PRIMARY OBJECTIVES: I. Determine an unknown normal immune response (T cell and B cell) to post-cryotherapy treatment for prostate cancer. II. Detect the altered immune response (T cell and B cell) post-GM-CSF (sargramostim) response and post-cryotherapy for the prostate cancer. Patients are randomized to 1 of 2 treatment arms. ARM I (TREATMENT): Patients undergo cryotherapy on day 0 and receive sargramostim subcutaneously (SC) on days 1, 3, 5, 8, 10, and 12. ARM II (CONTROL): Patients undergo cryotherapy on day 0. After completion of study treatment, patients are followed up for 6 months.


Minimum age: 18 Years. Maximum age: 85 Years. Gender(s): Male.
