Hyperpolarized Pyruvate (13C) MR Imaging in Monitoring Patients With Prostate Cancer on Active Surveillance

Is NCT03933670 recruiting? Yes, currently enrolling (Jun 2026). This Phase 2 trial studies Hyperpolarized Carbon C 13 Pyruvate for prostate adenocarcinoma.

Phase 2RecruitingUniversity of California, San FranciscoNCT03933670Data as of Jun 2026

Treatment: Hyperpolarized Carbon C 13 PyruvateThis phase II trial studies the side how well hyperpolarized carbon C 13 pyruvate (HP C-13 pyruvate) magnetic resonance imaging (MRI) works in monitoring patients with prostate cancer on active surveillance who have not received treatment. Diagnostic procedures, such as MRI, may help visualize HP C-13 pyruvate uptake and breakdown in tumor cells.
