Hyperpolarized Carbon C 13 Pyruvate Magnetic Resonance Spectroscopic Imaging in Predicting Treatment Response in Patients With Prostate Cancer
Study Details
Study Description
Brief Summary
This phase II trial studies how well hyperpolarized carbon C 13 pyruvate magnetic resonance spectroscopic imaging works in predicting treatment response in patients with prostate cancer. Hyperpolarized carbon C 13 pyruvate magnetic resonance spectroscopic imaging may help to accurately predict how prostate cancer patients will respond to standard therapy (abiraterone and apalutamide).

Detailed Description
PRIMARY OBJECTIVE:
- To assess reproducibility of quantitative spectroscopic and imaging parameters in hyperpolarized 13-C pyruvate magnetic resonance spectroscopic imaging (MRSI), including key performance indicator (kpl), which assesses the rate of conversion of 13-C pyruvate to 13-C lactate in the tissue of interest, using a test-retest study design.
SECONDARY OBJECTIVE:
- To provide initial assessment of the sensitivity and specificity of hyperpolarized 13-C-pyruvate MRSI performed pre-therapy for detecting high risk localized prostate cancer.
OUTLINE:
Patients receive hyperpolarized carbon C 13 pyruvate intravenously (IV) over 10-20 seconds and undergo MRSI over 2-3 minutes at 6 and 8 weeks.
After completion of study, patients are followed up at 1 day and then for up to 3 years.

Outcome Measures
Primary Outcome Measures
- Reproducibility of the key performance indicator [Up to 3 years]
Secondary Outcome Measures
- Sensitivity assessed by comparison to biopsy [Up to 3 years]
The location of signal by hyperpolarized 13-C-pyruvate will be compared to location of tumor at biopsy or if available, follow-up surgical pathology in patients who did not receive interval additional prostate directed therapy, such as hormonal or radiation therapy.
- Specificity assessed by comparison to biopsy [Up to 3 years]
The location of signal by hyperpolarized 13-C-pyruvate will be compared to location of tumor at biopsy or if available, follow-up surgical pathology in patients who did not receive interval additional prostate directed therapy, such as hormonal or radiation therapy.
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Biopsy proven high risk prostate adenocarcinoma, or de novo metastatic previously untreated naive prostate cancer (patients who have initiated gonadotrophin releasing hormone [Lhrh] analog or antagonist within the past 4 weeks are eligible)
-
Gleason >= 8 OR Gleason 7 + >= cT2b + prostate specific antigen (PSA) > 10 ng/ml
-
Prior prostate biopsy must have been performed at least 4 weeks prior
Exclusion Criteria:
-
Contraindication to MRI
-
Estimated glomerular filtration rate (eGFR) < 30
-
Allergy to gadavist intravenous contrast
-
History of cardiac arrhythmia
-
Since they do not get prostate cancer, women are excluded; thus, pregnancy is not an issue
