Intratumoral and Systemic Hiltonol® (Poly-ICLC) in Prostate Cancer Patients on Active Surveillance

Korábbi kezelés

• Received local or systemic curative therapy for prostate cancer

Más betegség

• Evidence of locally advanced disease
• Subject has evidence of any other malignancy
• Allergy to any antibiotics, as IT administration requires prophylactic antibiotics.

Egyéb

• Subjects with neuroendocrine tumors
• ISUP Gleason Grade Group (>3), or Gleason 3+3 plus PSA ≤ 10 or Stage ≤T2a

• Written informed consent and HIPAA authorization for release of personal health information.
  • NOTE: HIPAA authorization may be included in the informed consent or obtained separately.
• Age > 18 years at the time of consent.
• ECOG Performance Status of 0-1 within 14 days prior to being registered for protocol therapy (Study Procedure Manual).
• Histologically confirmed adenocarcinoma of the prostate (with previous diagnostic tissue available for tumor marker analysis).
• • ISUP Grade 1(Gleason 3+3) and Grade 2 (Gleason 3+4) and Grade 1 (Gleason 3+3, with PSA≥10, or stage ≥ T2b)
• Estimated life expectancy is ≥ 10 years
• Candidate for primary curative therapy (Radical prostatectomy or radiation) if cancer progresses.
• Tolerated previous transrectal ultrasound guided biopsy procedure under local anesthetic
  • Uncomplicated previous TRUS biopsy procedure (i.e., no prior hospitalization due to sepsis, prostatic abscess or severe hemorrhage following TRUS prostate biopsy)
• Willing to undergo the intratumoral (IT) injection of the Poly-ICLC into the prostatic tumor as per the protocol
• No prior hormonal therapy with exception of with the exception of oral 5-alpha-reductase inhibitors (finasteride, dutasteride, etc.). Subjects should be off the medication ≥ 6 months from screening
• No prior radiation therapy (external beam or brachytherapy) to the pelvis or prostate.
• No clinically significant infections as judged by the treating investigator.
• No characteristics suggesting a potential higher risk of infection with intraprostatic injections:
  • Recurrent urinary tract infections or history of prostatitis within 3 months prior to enrollment into the study.
  • Urine analysis positive for nitrites and leucocyte esterase. Such subjects could be considered for the study after treatment and resolution of the infection.
  • Active proctitis
  • History of prostatic abscess
  • Taking immunosuppressive medication including systemic corticosteroids
  • Active hematologic malignancy
• No uncontrolled angina, congestive heart failure or MI within 6 months.
• Subjects with history of HIV (if CD4+ T cell counts are ≥350 cells/μL on established ART therapy), Hepatitis B (with viral load below limits of quantification) or Hepatitis C (who have completed a curative therapy and have a viral load below the limit of quantification) are eligible for this study.
• No treatment with any investigational agent for any medical condition within 28 days prior to being registered for protocol therapy.
• Patients with the potential for impregnating their partner must agree to follow acceptable birth control methods to avoid conception. Contraception must be continued for at least 2 months following the last dose of poly-ICLC. While animal reproductive studies have been negative, the simulated viral infection and anti-proliferative activity of this experimental drug may theoretically affect the developing fetus or nursing infant.
• Adequate end organ function as determined by the following laboratory values:
  • White blood cell count (WBC) ≥ 2.5 k/mm\^3
  • Absolute neutrophil count (ANC) ≥ 1.5 k/mm\^3
  • Hemoglobin (Hgb) ≥ 8.0 g/dL
  • Platelets ≥ 100 k/mm\^3
  • Calculated creatinine clearance of > 60 cc/min using the Cockcroft-Gault formula:
  • Males: [(140 - Age in years) × Actual Body Weight in kg]/[72 × Serum Creatinine (mg/dL)]
  • Bilirubin ≤ 2.0 x ULN
  • Aspartate aminotransferase (AST) ≤ 2.5 x ULN
  • Alanine aminotransferase (ALT) ≤ 2.5 x ULN
