Peptide-specific Vaccination in HLA-A*02 Positive Patients With Biochemical Recurrence After Radical Prostatectomy

August 14, 2017 updated by: University Hospital Tuebingen

Prospective Randomized Trial of Peptide-specific Vaccination in HLA-A*02 Positive Prostate Carcinoma Patients With Biochemical Recurrence After Radical Prostatectomy

The study evaluates the prostate-specific antigen (PSA) response in HLA-A*02 positive patients with biochemical recurrence after radical prostatectomy treated with a prostate-specific peptide vaccine in combination with different immune-adjuvants.
