  Purpose

RATIONALE: Vaccines made from tumor cells may help the body build an effective immune response to kill tumor cells.

PURPOSE: This randomized phase II trial is studying vaccine therapy to see how well it works compared with a placebo in treating patients with stage D0 prostate cancer.


Condition Intervention Phase

Biological: BCG vaccine
Biological: prostate cancer vaccine ONY-P1

Secondary Outcome Measures:
  • Toxicity [ Designated as safety issue: Yes ]
  • Immunologic response as assessed by ELISPOT assay [ Designated as safety issue: No ]
  • PSA kinetics (doubling time/velocity) of treatment [ Designated as safety issue: No ]
  • Time to testosterone recovery [ Designated as safety issue: No ]

Estimated Enrollment: 54
Study Start Date: March 2007
Estimated Primary Completion Date: September 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm I
Patients receive ONY-P1 vaccine with BCG intradermally on days 1 and 15. Patients then receive ONY-P1 vaccine alone on day 29 and then every 4 weeks for up to 12 months in the absence of disease progression or unacceptable toxicity.
Biological: BCG vaccine
given intradermally
Biological: prostate cancer vaccine ONY-P1
given intradermally
Placebo Comparator: Arm II
Patients receive placebo vaccine intradermally on days 1, 15, and 29 and then every 4 weeks for up to 12 months in the absence of disease progression or unacceptable toxicity.
Other: placebo
given intradermally

Detailed Description:

OBJECTIVES:

Primary

  • To determine whether ONY-P1 vaccine can increase the time to PSA-defined progression in patients with androgen-dependent stage D0 prostate cancer.

Secondary

  • To evaluate all toxicities related to ONY-P1 vaccine.
  • To compare the immunologic response in patients treated with ONY-P1 vaccine vs placebo.
  • To evaluate PSA kinetics (doubling time/velocity) of treatment.
  • To evaluate time to testosterone recovery following limited androgen ablation.

OUTLINE: Patients are stratified according to estimated PSA doubling time (< 12 months vs ≥ 12 months).

Patients receive goserelin subcutaneously once. Approximately 3 months later, patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive ONY-P1 vaccine with BCG intradermally on days 1 and 15. Patients then receive ONY-P1 vaccine alone on day 29 and then every 4 weeks for up to 12 months in the absence of disease progression or unacceptable toxicity.
  • Arm II: Patients receive placebo vaccine intradermally on days 1, 15, and 29 and then every 4 weeks for up to 12 months in the absence of disease progression or unacceptable toxicity.

After completion of study therapy, patients are followed periodically for up to 15 years.

Criteria

DISEASE CHARACTERISTICS:

  • Biochemical progression, as defined by the following:

    • A rise in PSA of ≥ 2 ng/mL above the nadir (for patients previously treated with definitive radiotherapy or cryotherapy)
    • Two consecutive rises in PSA > 0.3 ng/mL (for patients previously treated with radical prostatectomy)
  • PSA ≤ 20 ng/mL
  • Testosterone ≥ lower limit of normal
  • Negative CT scan and bone scan for metastatic prostate cancer
  • No clinically active brain metastases

PATIENT CHARACTERISTICS:

  • ECOG performance status of 0-1
  • Life expectancy ≥ 6 months
  • Granulocyte count ≥ 1,500/mm³
  • Platelet count ≥ 100,000/mm³
  • Hemoglobin ≥ 10 g/dL
  • Bilirubin ≤ 1.5 mg/dL OR total bilirubin ≤ 3.0 mg/dL (in patients with Gilbert's syndrome)
  • AST and ALT ≤ 2.5 times upper limit of normal
  • No other active malignancies within the past 60 months (with the exception of nonmelanoma skin cancer or carcinoma in situ of the bladder)
  • No life-threatening illnesses
  • No immunocompromised status due to any of the following:

    • HIV positivity
    • Active autoimmune diseases, such as Addison's disease, Hashimoto's thyroiditis, systemic lupus erythematosus, Sjögren syndrome, scleroderma, myasthenia gravis, Goodpasture syndrome, or active Grave's disease

      • Patients with a history of autoimmunity that has not required systemic immunosuppressive therapy or does not threaten vital organ function, including CNS, heart, lungs, kidneys, skin, or gastrointestinal tract, will be allowed
    • Other immunodeficiency diseases or iatrogenic immunodeficiency from drugs
  • No other serious medical illness that would interfere with the patient's ability to carry out the treatment program
