Intervention name:
Magnetic Resonance imaging
Description:
Magnetic resonance imaging is a medical imaging technique used in radiology to form
pictures of the anatomy and the physiological processes of the body
Arm group label:
Pre-surgical participants with prostate cancer
Other name:
Magnetic Resonance scan
Other name:
MR scan
Summary:
This is a single site, prospective pilot study to determine the feasibility and safety of
the administration of HP 13C bicarbonate in 10 patients with prostate cancer to determine
potential hydrogen (pH) values in surrounding tissue. The proposed study will evaluate
pre-surgical participants with histologically confirmed localized prostate cancer who
receive infusion of hyperpolarized 13C injection prior to MR imaging with endorectal
coil.
Detailed description:
PRIMARY OBJECTIVE:
I. To determine the feasibility of tumor pH measurement in men with prostate cancer using
hyperpolarized 13C bicarbonate imaging.
SECONDARY OBJECTIVE:
I. To determine the safety of administration of hyperpolarized 13C-bicarbonate.
EXPLORATORY OBJECTIVES:
I. To correlate the measurement of tissue pH with pathologic grade.
II. To correlate tissue pH maps with immunohistochemistry staining (IHC), gene expression
(RNA-Seq), and spatial transcriptomics. *Bristol Myers Squibb (BMS) collaboration
OUTLINE:
Men with biopsy-proven adenocarcinoma of the prostate scheduled to undergo radical
prostatectomy at University of California, San Francisco (UCSF) within 12 weeks of
enrollment will receive infusion with hyperpolarized 13C bicarbonate and undergo
metabolic MR imaging with endorectal coil. Participants will be followed for 5-9 days
after the hyperpolarized 13C-bicarbonate injection, or removal from study, or until
death, whichever occurs first. Participants removed from study for unacceptable study
related adverse event(s) will be followed until resolution or stabilization (as
determined by the investigator) or until initiation of new anti-cancer therapy, whichever
occurs first.
Criteria for eligibility:
Criteria:
Inclusion Criteria:
1. Patients age >=18 years.
2. Patients must have biopsy-proven adenocarcinoma of the prostate; biopsy may be
performed outside of University of California, San Francisco (UCSF) if detailed
results of sextant biopsy are available.
3. Tumor size of at least 1.0 cm in long axis on Magnetic resonance imaging (MRI) or
ultrasound; if no prior imaging is available, at least 3 cores positive on biopsy.
4. Patients must have planned radical prostatectomy at UCSF within 12 weeks following
protocol MRI/ magnetic resonance spectroscopy imaging) (MRSI).
5. Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1.
6. Demonstrates adequate organ function as defined below:
1. Adequate bone marrow function:
- Absolute neutrophil count >=1,500 cells/µL.
- Platelets >=75,000 cells/µL.
- Hemoglobin >=9.0 gm/dL.
2. Adequate hepatic function:
- Total bilirubin <1.5x upper limits of normal (ULN) (within normal
institutional limits, unless elevated due to Gilbert's syndrome and direct
bilirubin is within normal limits).
- Aspartate aminotransferase (AST)/serum glutamic-oxaloacetic transaminase
(SGOT) <=1.5 X institutional upper limit of normal.
- Alanine aminotransferase (ALT)/serum glutamic-pyruvic transaminase (SGPT)
<=1.5 X institutional upper limit of normal.
3. Adequate renal function:
- Creatinine clearance >= 50 calculated using the Cockcroft-Gault equation,
unless data exists supporting safe use at lower kidney function values, no
lower than 30 mL/min/1.73 m^2.
7. Ability to understand and the willingness to sign a written informed consent
document.
Exclusion Criteria:
1. Patients who because of general medical or psychiatric condition, or physiologic
status, cannot give valid informed consent.
2. Patients unwilling or unable to undergo MR imaging, including patients with
contraindications to Magnetic resonance imaging (MRI) as per UCSF radiology
departmental guidelines.
3. Patients who cannot tolerate or have contra-indications to endorectal coil
insertion, for example, patients with a prior abdominoperineal resection of the
rectum or latex allergy.
4. Patients with contra-indications to injection of gadolinium contrast as per UCSF
radiology departmental guidelines.
5. Patients who take carbonic anhydrase inhibitors (e.g. acetazolamide,
dichlorphenamide, methazolamide).
6. Metallic hip implant or any other metallic implant or device that distorts local
magnetic field and compromises the quality of MR imaging.
7. Cryosurgery, surgery for prostate cancer, prostatic or pelvic radiotherapy prior to
study enrollment. No limit on number of prior prostate biopsies. Prior Transurethral
Resection of the Prostate (TURP) is not allowed.
8. Poorly controlled hypertension, with blood pressure at study entry >160/100. The
addition of anti-hypertensives to control blood pressure is allowed for eligibility
determination.
9. Congestive heart failure or New York Heart Association (NYHA) status >= 2. A history
of clinically significant electrocardiogram (EKG) abnormalities, including QT
prolongation, a family history of prolonged QT interval syndrome, or myocardial
infarction (MI) within 6 months of study entry. Patients with rate-controlled atrial
fibrillation/flutter will be allowed on study.
