Assessment

Primary outcomes

Assessment of immune responses by measurement of cytotoxic T lymphocytes (CTL)and anti-peptide IgG) before and after peptide vaccination.

Key secondary outcomes

1. Evaluation of long-term prognosis (progression free survival and overall survival).
2. Adverse effects of peptide vaccination / The safety of the protocol is evaluated based on the NCI-CTC.
3. Evaluation of mild bone marrow suppression, as well as immune responses enhancing effects of functional food nutrition.

Interventions/Control_1

1st treatment (total 8 times, every weeks):
4 peptide vaccines are selected from 31 peptide candidates restricted by HLA-class I, to which peptide-specific IgGs are detected before vaccination, and administer peptides (maximum 4) that showed the highest reactivity. Emulate these peptides individually and subcutaneously inject them separately (3.0 mg/1.5-3.0 ml/peptide) every 1 week interval.
After the first cycle of 8 vaccinations, the peptides were re-selected according to the titers of peptide-specific IgG at every cycle of 8 vaccinations and administered at 2, 3, or 4 week intervals until unacceptable toxicity or withdrawal of consent.

Key inclusion criteria

The subjects must satisfy the following conditions.
1) Patients must be diagnosed as prostate cancer pathologically at the initial treatment. The patients must be suffering from castration-resistant prostate cancer after standard treatment.
2) Patients must be at a score level of 0-1 of performance status (PS) (ECOG).
3) Patients must be positive for HLA-A2, HLA-A24 or HLA-A3 super type.
4) Patients must have IgG reactive to at least two of peptide candidates.
5) Patients must satisfy the followings:
WBC > and = 2,500/mm3
Lymphocyte 500- 1,000/mm3
Hb > and = 8.0g/dl
Platelet > and = 50,000/mm3
Serum Creatinine < and = 2.5x upper limit of normal
Total Bilirubin < and = 2x upper limit of normal
6) Patients must be more 20 year-old.
7) Patients must be expected to survive more than 3 months.
8) Written informed consent must be obtained from patients.


Key exclusion criteria

he following patients must be excluded:
1) Patients with severe symptoms (active and severe infectious disease, circulatory disease, respiratory disease, kidney disease, immunodeficiency, disturbance of coagulation).
2)Active double cancer (synchronous double cancer and metachronous double cancer within 5 disease-free years), excluding carcinoma in situ (lesions equal to intraepithelial or intramucosal cancer) judged to have been cured with local treatment.
3) Patients with the past history of severe allergic reactions.
4) Patients who are judged inappropriate for the clinical trial by doctors.
