Magnetic Resonance (MR) Imaging With Hyperpolarized 13C-Pyruvate +/- 13C,15N-Urea in Patients With Prostate Cancer

Korábbi kezelés

• Prostate biopsy performed within 14 days prior to baseline C-13 HP pyruvate MRI.
• Poorly controlled hypertension, with blood pressure at study entry > 160 mm Hg systolic or > 100 mm Hg diastolic. Treatment with anti-hypertensives and re-screening is permitted.

Más betegség

• Evidence of pelvic regional or distant metastatic disease on conventional imaging (MRI, computed tomography or whole body bone scan) or prostate-specific membrane antigen (PSMA) Positron Emission Tomography (PET) imaging. PSMA-avid lymph nodes confined to the pelvis will be allowed if <1 centimeter (cm).
• Contraindication to or inability to tolerate MRI with endorectal coil (e.g. severe claustrophobia, presence of cardiac pacemaker, aneurysm clip, severe or painful hemorrhoids, rectal stricture).
• Congestive heart failure with New York Heart Association (NYHA) status >= 2.

Laborértékek

• History of clinically significant ECG abnormality, including QT prolongation, a family history of prolonged QT interval syndrome or myocardial infarction within 6 months of study entry.

• Participants must have biopsy-proven adenocarcinoma of the prostate, as determined by medical chart review.
• For:
  • Part 1: Participants post-radiation therapy or currently considering EBRT.
  • Part 2A: Participants currently scheduled for or considering EBRT (no neo-adjuvant therapy planned).
  • Part 2B: Participants currently scheduled for or considering EBRT and neo-adjuvant therapy is planned. The participant has biopsy-proven adenocarcinoma of the prostate with high-risk disease, defined by the presence of at least two of following criteria: a tumor stage of T3 or T4, a Gleason score of 8 to 10, or a PSA level ≥40 ng/mL) and the participant must be planning to receive androgen deprivation therapy (ADT) with an Luteinizing hormone-releasing hormone (LHRH) agonist or antagonist. The addition of an androgen-receptor (AR) signaling inhibitor (e.g., abiraterone, bicalutamide,apalutamide, enzalutamide or darolutamide) will be allowed.
  • Part 3: Participants who have previously received radiation treatment to the prostate and are exhibiting signs of biochemical failure, with planned fusion biopsy within 12 weeks following completion of baseline HP 13C pyruvate +/-urea mpMRI.
• Participant is able and willing to comply with study procedures and provide signed and dated informed consent.
• Eastern Cooperative Oncology Group (ECOG) performance status <= 1.
• Age >= 18 years old at time of study entry.
• Ability to understand and the willingness to sign a written informed consent document.
• Demonstrates adequate organ function as defined below:
  • White Blood Cell count (WBC) >=4000 cells/μL.
  • Hemoglobin ≥9.0 gm/dL.
  • Platelets ≥75,000 cells/μL.
  • Renal Function > 30 Epithelial Growth Factor Receptor (eGFR).
