Prostate Cancer Clinical Trial

Development and Evaluation of a Quantitative HP MRI for Clinical Prostate Cancer Exam

Summary

This trial examines if a prostate magnetic resonance spectroscopic imaging can be performed on a 3T scanner using an investigational contrast called hyperpolarized 13-C pyruvate for the development of a clinical prostate cancer exam. 3T refers to the strength of the magnetic resonance spectroscopic imaging (MRSI) machine. MRSI is a magnetic resonance imaging (MRI) technique that can show certain chemical differences in healthy and diseased prostate tumor tissue compared to standard multiparametric MRI that may not detect the tumor. Hyperpolarized (HP) 13-C pyruvate is a contrast drug that may help the scanner see the tumor site better during imaging. Hyperpolarization of 13-C pyruvate may allow pyruvate and its metabolites to be detected upon injection, which in turn, allow the prostate cancer to be found and treated.

PRIMARY OBJECTIVES:

I. To assess reproducibility of quantitative spectroscopic and imaging parameters in hyperpolarized 13-C pyruvate magnetic resonance spectroscopic imaging (MRSI), including 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.

II. To test the reproducibility of the normalized area under the lactate curve (nLac), a semi-quantitative biomarker for tumor metabolism.

SECONDARY OBJECTIVES:

I. 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.

II. To assess the correlation between kpl and tumor grade.

OUTLINE: Patients are assigned to 1 of 3 arms.

ARM Ia: Patients receive hyperpolarized carbon C 13 pyruvate intravenously (IV) and undergo MRSI at least 5 weeks after prostate cancer biopsy.

ARM Ib: Patients receive hyperpolarized carbon C 13 pyruvate IV and undergo MRSI at least 5 weeks after prostate cancer biopsy and at a second time 3-4 weeks after.

ARM II: Patients receive hyperpolarized carbon C 13 pyruvate IV and undergo MRSI at least 5 weeks after prostate cancer biopsy, followed by standard of care surgery within 6 months after.

After the completion of study, patients in Arm Ia and Arm Ib are followed up once.
