Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations

The study was activated on February 3, 2006 and terminated on December 11, 2007 after reaching its accrual goal. A total of 50 patients were recruited from ECOG member institutions.

Patients with biochemical or clinical progression during Step 1 were eligible to receive androgen blockade in Step 2. To date, 31 patients have registered to Step 2.

  Description
Vaccinia/Fowlpox/GM-CSF

There are two steps in this study. Patients receive vaccine treatment in Step 1. Patients with biochemical or clinical progression during Step 1 were eligible to continue on to androgen blockade in Step 2. This report includes information collected in Step 1 only.

Patients receive vaccinia subcutaneously (SC) on day 1 and GM-CSF SC on days 1-4 during cycle 1. Beginning with cycle 2, patients receive fowlpox SC on day 1 and GM-CSF SC on days 1-4. Treatment with fowlpox and GM-CSF repeats every 4 weeks for 2 courses. Beginning in week 13, patients receive fowlpox and GM-CSF as above every 12 weeks in the absence of clinical or biochemical disease progression or unacceptable toxicity.

Patients with biochemical or clinical disease progression may start Step II androgen ablation therapy comprising oral bicalutamide once daily for 1 month and goserelin SC once every 4 weeks in addition to fowlpox vaccine and GM-CSF until further progression or a max of 12 months.
