Detailed Description:

This is an open-label, fixed-dose study of immunization with NY-ESO-1 protein combined with CpG 7909 as adjuvant in patients with histopathologically confirmed metastatic cancer of the prostate, who have progressive disease under hormonal and/or chemotherapeutic treatment (duration of treatment > 3 months).

Eligible patients will receive vaccinations consisting of 100µg NY-ESO-1 protein combined with 2.5 mg CpG 7909 administered intradermally every 3 weeks for 4 doses. Twelve (12) patients will be enrolled into this study.

Blood samples will be obtained at baseline, prior to the second, third and fourth injection and three weeks after the fourth injection for clinical hematology, biochemistry and immune response assessments. Blood samples for antinuclear antibody (ANA) and anti-dsDNA will be collected at baseline and end of each study cycle.

A tumor sample, resected prior to immunization, will be tested to determine NY-ESO-1 and/or LAGE-1 expression.

DTH testing will be performed with NY-ESO-1b in HLA-A2+ patients and with NY-ESO-1 DP4 in HLA-DP4+ patients at baseline and at the 3-week visit following the second and fourth vaccinations.

NY-ESO-1 and/or LAGE-1 specific antibodies will be assessed in all patients by Western Blot and ELISA. NY-ESO-1 specific CD4+ and CD8+ T cells will be assessed by ELISPOT analysis in all patients.

Disease status will be assessed at baseline and 3 weeks after the fourth vaccination in patients with measurable disease.

Patients who demonstrate stable disease, minor response, partial response, or complete response on week 13 may continue to receive vaccinations until disease progression. In patients with mixed response, single progressive lesions may be resected and vaccination may be continued.

Resected metastases should be typed for NY-ESO- and/or LAGE-1 expression.

Criteria

Inclusion Criteria:

  1. Patients must have high-risk stage D1 or metastatic prostate cancer (D2), confirmed by review of histology.
  2. Patients must have fully recovered from surgery.
  3. Patients must show stable or progressive disease as assessed by X-ray, ultrasound, and/or CT scans under hormonal and/or chemotherapeutic treatment, that had been administered for at least three months.
  4. Any pretreatment with chemo- or radiotherapy must have been discontinued for at least four weeks prior to first dose of study agent. Hormone therapy is allowed before and throughout the study.
  5. Patients must have an expected survival of at least three months.
  6. Patients must have a Karnofsky performance status of 70% or more.
  7. Within the last 2 weeks prior to study day 1, vital laboratory parameters should be within normal range, except for the following laboratory parameters, which should be within the ranges specified:

    • Leukocytes >3.000/ul
    • Lymphocytes >700/ul
    • Platelets >100.000/ul
    • Serum creatinine <2.5 mg/dl
    • ALT, AST, and total bilirubin all < 2.5 x ULN
  8. Age ≥ 18 years
  9. Able to give valid written informed consent.

Exclusion Criteria:

  1. Clinically significant heart disease (NYHA Class III or IV).
  2. Other serious illnesses, eg, active infections requiring antibiotics, bleeding disorders.
  3. Concomitant systemic treatment with corticosteroids. Topical or inhalational steroids are permitted.
  4. Metastatic disease to the central nervous system.
  5. Mental impairment, in the opinion of the investigator, that may compromise the ability to give informed consent and comply with the requirements of the study.
  6. Lack of availability for immunological and clinical follow-up assessments.
  7. Participation in chemotherapy, radiation therapy, or any other clinical trial involving another investigational agent within 4 weeks prior to first dosing.
  8. Being a recipient of an organ or bone marrow allograft. Having an autoimmune disease other than vitiligo, such as, but not limited to, inflammatory bowel disease or multiple sclerosis.
