Brief Summary:
In this study the investigators will include patients with high risk of PSA relapse scheduled to receive curative surgical treatment. This include patients with high Gleason score (9-10) or micrometastatic disease (tumor cells detected in specimens obtained from bone marrow). They are scheduled for regular follow-ups with PSA measurements. We have previously published that some patients with metastatic prostate cancer may respond to DC-vaccination with tumor mRNA, with a decrease in PSA. PSA response is related to immunological response. Patients receiving DC-vaccination may have a reduced risk of PSA relapse or increased time to PSA relapse. Previous experience with different DC-vaccine protocols in our hospital has resulted in only minor side-effects (grade 1-2 fever, rubor, fatigue, local swelling or pain).

Secondary Outcome Measures :
  1. Safety and toxicity of vaccination. Evaluation of immunological response. [ Time Frame: Up to 8 years after vaccination ]

Other Outcome Measures:
  1. Efficacy Outcome Measure Efficacy Outcome Measure Percentage of patients with a second positive bone marrow examination at the End of Treatment [ Time Frame: Up to 36 month ]
  2. Time to PSA levels > 0.5 μg/L defined by two different measurement of PSA levels > 0.5 μg/L with minimum of 4 weeks interval in patients included by signing the informed concent form, but not receiving treatment [ Time Frame: From date of vaccination until the date of first documented treatment failure, assessed up to 8 years ]
    Pathological stage pT2 - pT3b and Gleason score 7B-8, pN0, pN+ or pNx. Negative bone marrow examination

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Older Adult)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Radical prostatectomy. Preferably accessible tumor tissue with enough volume and quality for vaccine production (extraction of tumor mRNA).
  • Pathological stage pT2 - pT3b and Gleason score 7B-10, pN0, pN+ or pNx.
  • Must be ambulatory with an ECOG performance status 0 or 1.
  • Tumor cells detected in bone-marrow samples (micrometastatic disease). Patients with Gleason score 9-10 or pT3b Gleason score 8 may also be included with negative bone-marrow aspiration. Bone-marrow aspirates and plasma for microRNA will be obtained before start of surgery.
  • Must be at least 18 years of age and less than 75 years.
  • PSA < 0.2 µg/L within 6 weeks after surgery.
  • Must have lab values as the following:

ANC ≥ 1.5 x 109/L; Platelets ≥ 100 x 109/L; Hb ≥ 9 g/dL (≥ 5.6 mmol/L); Creatinine ≤ 140 μmol/L (1.6 mg/dL)- if borderline, the creatinine clearance ≥ 40 mL/min; Bilirubin within the upper limit of normal; ASAT and ALAT ≤ 2.5 the upper limit of normal; Albumin levels above lower normal value

  • No metastasis on bone scans or MRI, last 3 months before inclusion.
  • Signed informed consent and expected cooperation of the patients for the treatment and follow up must be obtained and documented according to ICH/GCP, and national/local regulations.

Exclusion Criteria:

  • Previous treatment with LHRH (Luteinizing Hormone-Releasing Hormone) agonist.
  • Previous anti-androgen treatment (Casodex).
  • History of prior malignancy within the last 5 years, with the exception of curatively treated basal cell carcinoma.
  • Active infection requiring antibiotic therapy.
  • Significant cardiac or other medical illness that would limit activity or survival, such as severe congestive heart failure, unstable angina, or serious cardiac arrhythmia.
  • Adverse reactions to vaccines such as asthma, anaphylaxis or other serious reactions.
  • History of immunodeficiency or autoimmune disease such as rheumatoid arthritis, systemic lupus erythematosus, scleroderma, polymyositis-dermatomyositis, juvenile onset insulin dependent diabetes, or a vasculitic syndrome.
  • Positive testing for syphilis (treponema pallidum), HIV, Hepatitis B and C
  • Use of systemic glucocorticoids.
  • Any reason why, in the opinion of the investigator, the patient should not participate.
