  Purpose

In this study, up to 21 patients with metastatic prostate cancer will receive UV1 (a therapeutic synthetic peptide vaccine) at different dose levels. The safety and tolerability of UV1 as well as immunological response will be assessed. The purpose of this study is to select a biological dose of peptides for further clinical trials.

Main treatment period is completed and reported. Follow-up ongoing.

Primary Outcome Measures:
  • Assessment of safety and tolerability of UV1 [ Time Frame: up to 9 months ]
    Frequency and severity of adverse events and serious adverse events. Biochemistry and hematology results, vital signs and ECOG performance status will be assessed.

  • Immunological response [ Time Frame: Up to 9 months ]
    Number of T-cell responses including time to T-cell responses (up to 6 months), level of response and duration of response.


Secondary Outcome Measures:
  • Selection of biological dose of peptides for further clinical trials [ Time Frame: up to 9 months ]
    Safety profile and immunological responses of each dose level.


Other Outcome Measures:
  • Assessment of anti tumor activity; (sPSA measurements and multiparametric radiological assessments). [ Time Frame: Up to 6 months ]
    Tumor response, progression free survival (PFS), and changes in antineoplastic treatment

  • Potential correlation between human cytomegalovirus status and immune response. [ Time Frame: Up to 9 months ]
    Determination of human cytomegalovirus (CMV) status

  • Further characterization of the immune reaction triggered by the treatment. [ Time Frame: Up to 6 months ]
    T-cell infiltration of the prostatic gland after 6 months and compared to the initial multiparametric MRI.

  • Identification of prognostic surrogate markers. [ Time Frame: Up to 6 months ]

    Genetic analyses (DNA), gene expression profiling (RNA), proteomics, metabolomics from samples (blood, urine, tissue) collected at Baseline and repeated after 6 months (blood, urine).

    Circulating tumor cells will be measured at baseline and month 6.

Arms Assigned Interventions
Experimental: UV1 synthetic peptide vaccine and GM-CSF

Biological: UV1 synthetic peptide vaccine and GM-CSF
Other Names:
  • UV1
  • Leukine

Detailed Description:

The study is an open labeled dose-escalating phase I/IIa study of UV1 peptide vaccination in patients with androgen-sensitive metastatic prostate cancer. Patients will be prospectively enrolled in this study if diagnosis of adenocarcinoma only has been histologically confirmed and they are eligible for (or have already started up to 6 months prior to inclusion) standard GnRH-agonist first line androgen deprivation therapy (ADT) combined with anti-androgen to achieve complete androgen blockade (CAB). UV1 vaccinations will be applied simultaneously with CAB.

When indicated, patients may receive concomitant radiotherapy.

The following 2-step design will be used:

  1. Conventional dose escalation with at least 3 patients per dose level (3 selected dose levels).
  2. Expansion of each dose level to a total of 7 patients for assessment of immune response levels

13 UV1 vaccinations will be given during the first 6 months (week 26) of treatment, unless clinical deterioration or unacceptable toxicity is encountered. GM-CSF (Leukine ®) will be administered locally 10-15 minutes before each UV1 vaccination.

Hormone naïve patients will receive standard complete androgen blockade by GnRH-agonist (3 months depot formulation sc.) and bicalutamide 50 mg orally per day (CAB). Patients already on GnRH-agonist therapy will continue with their initial treatment with addition of bicalutamide 50 mg orally per day.

    • Platelets ≥ 100 x 109/L
    • Hemoglobin ≥ 9g/dL (≥ 5.6 mmol/L)
    • Creatinine ≤ 140 µmol/L; if creatinine is borderline, the creatinine clearance ≥ 40 mL/min;
    • Bilirubin < 20% above the upper limit of normal
    • ASAT and ALAT ≤ 1.5 the upper limit of normal
    • Albumin ≥ 2.5 g/L
    • Normal NSE
    • sPSA < 200 ng/mL.
  • Signed informed consent

Exclusion Criteria:

  • History of other prior malignancy, with the exception of curatively treated basal cell or squamous cell carcinoma of the skin or effectively treated malignancy that has been in remission for over 5 years and is highly likely to have been cured.
  • Treatment with any other investigational medicinal product (IMP) within 4 weeks prior to first administration of study drug.
  • Adverse reactions to vaccines such as anaphylaxis or other serious reactions.
  • History of immunodeficiency or autoimmune disease such as rheumatoid arthritis, systemic lupus erythematosus, sclerodermia, polymyositis-dermatomyositis, juvenile onset insulin-dependent diabetes, or a vasculitic syndrome.
  • Significant cardiac or other medical illness that would limit activity or survival, such as severe congestive heart failure, unstable angina, or serious cardiac arrhythmia.
  • Active infection requiring antibiotic therapy.

  • Known hypersensitivity to Leukine®, yeast derived products or any component of the product
  • Patients who test positive for hepatitis B, C or HIV
  • Any other anti-tumor treatment (including chemotherapy, immunotherapy, cytokines, interferons, protease inhibitors and gene therapy) administered with the exception of GnRH-agonist with or without bicalutamide started up to 6 months prior inclusion.
  • Use of not permitted concomitant medication:

    • any agent with a known effect on the immune system, unless it is being given at dose levels that are not immunesuppressive, e.g. prednisone at 10mg/day or less
    • any alternative and complementary drugs that may affect the immune system or be potentially harmful to patients participating in phase I studies.
  • Any reason why, in the opinion of the investigator, the patient should not participate.
