Official Title

A Randomized, Double-blind, Phase 3 Efficacy Trial of PROSTVAC-V/F +/- GM-CSF in Men With Asymptomatic or Minimally Symptomatic Metastatic Castrate-Resistant Prostate Cancer

Eligibility Criteria

Ages Eligible for Study: Older than 18 Years
Sexes Eligible for Study: Male
Accepts Healthy Volunteers: No
Inclusion Criteria:
  1. Men, ≥18years of age with documented asymptomatic or minimally symptomatic metastatic castration-resistant prostate cancer. Documented progressive disease post surgical castration or during androgen suppression therapy, or during complete androgen blockade therapy and withdrawal. Documented by either criterion a (Radiological progression), OR criterion b (PSA progression). 1. Radiological progression defined as any new/enlarging bone metastases or new/enlarging lymph node disease, consistent with prostate cancer. OR 2. PSA progression defined by sequence of rising values separated by > 1 week (2 separate increasing values) over a threshold minimum of 2.0 ng/ml. (PCWG2 PSA eligibility criteria). Chemotherapy naïve and Vaccinia-experienced (previous smallpox vaccination). Currently using a GnRH agonist or antagonist (unless surgically castrated).
Exclusion Criteria:
  1. Cancer-related pain requiring scheduled opioid narcotics for control (as needed, ≤ 2x per week is allowed). Metastasis to organ systems other than lymph nodes and/or bone. Estimated PSA doubling time of <1 month as established within 6 months of the anticipated first dose of vaccine or placebo. Concurrent or prior Provenge (sipuleucel-T) immunotherapy for prostate cancer. Receipt of an investigational agent within 30 days (or 60 days for an antibody-based therapy) of the first planned dose of PROSTVAC-V/F. History of prior malignancies other than prostate cancer within the past 3 years, excluding successfully resected basal or squamous cell carcinoma of the skin. Congestive heart failure (NYHA Class II, III, or IV), unstable angina, ventricular or hemodynamically significant atrial arrhythmia, or cardiovascular disease such as stroke or myocardial infarction (current or within the past 6 months) Confirmed positive for HIV, hepatitis B, and /or hepatitis C. Immunodeficiency or splenectomy. History of or active autoimmune disease, persons with vitiligo are not excluded. Diabetics are not excluded if the condition is well controlled.
