Spots Global Cancer Trial Database for Phase 1A/1B Study of PSA/IL-2/GM-CSF Vaccine for Recurrent Prostate Cancer in Hormone Naive and Hormone Independent Patients

Study Description

Brief Summary: This study is investigating the safety and efficacy of a vaccine directed against prostate tumor cells. The researchers are interested in evaluating the safety and tolerability of the vaccine, and the effects of the vaccine on survivability, time to measurable disease, prostate-specific antigen (PSA) level in the blood, and the immune response to the vaccine. Eligible patients include those with recurrent prostate cancer as shown by elevated levels of PSA, although there is no evidence of tumors that are measurable by imaging studies. In addition, to be eligible patients must have prostate cancer that either has not been treated by hormonal therapy or is not responsive to hormonal therapy.

Detailed Description: In Phase 1A, hormone naive and hormone independent patients are enrolled in a 1:1 ratio. All patients receive intradermal injections of the PSA/IL-2/GM-CSF induction vaccine at Weeks 1, 2, 3, 7, 11 and 15. In Phase 1B, which will be initiated after Phase 1A, will first receive the induction vaccine (PSA/IL-2/GM-CSF) according to the same schedule as patients in Phase 1A. Then, in eligible Phase 1B patients, following the induction vaccine regimen, alternating maintenance vaccination will be administered as follows: at Weeks 23, 31, and 39, IL-2 alone will be administered; at Weeks 27, 35, and 43, the complete vaccine (PSA/IL-2/GM-CSF) will be administered.
