Magnetic Resonance (MR) Imaging With Hyperpolarized Pyruvate (13C) in Castration-Resistant Prostate Cancer

2016-09-22 20:53:27 | BioPortfolio


This is a prospective imaging study evaluating the utility of baseline metabolic MR imaging with Hyperpolarized Pyruvate (13C) as a predictive response biomarker to androgen signaling inhibition in patients with castration-resistant prostate cancer.


This is a prospective imaging study evaluating the utility of baseline metabolic MR imaging as a predictive response biomarker to androgen signaling inhibition in patients with castration-resistant prostate cancer. Patients with a target lesion that is amenable for metabolic MR imaging will be eligible for study participation. Patients will undergo baseline metabolic MR imaging with Hyperpolarized Pyruvate C-13 pyruvate followed by initiation of androgen signaling inhibition (either as standard of care or as part of clinical trial; including abiraterone and/or enzalutamide treatment). Patient will subsequently undergo repeat metabolic MR scan after 28 days (+/- 7 days) of therapy. For those without primarily refractory disease, a third metabolic MR scan will be completed at the time of radiographic disease progression by PCWG2 criteria. MR- or CT-guided tumor biopsies are optional at baseline and at the time of disease progression.

Medical and Biotech [MESH] Definitions

A glycoprotein that is a kallikrein-like serine proteinase and an esterase, produced by epithelial cells of both normal and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer.

A synthetic retinoid that is used orally as a chemopreventive against prostate cancer and in women at risk of developing contralateral breast cancer. It is also effective as an antineoplastic agent.

Tissue ablation of the PROSTATE performed by ultrasound from a transducer placed in the RECTUM. The procedure is used to treat prostate cancer (PROSTATIC NEOPLASMS) and benign prostatic hypertrophy (PROSTATIC HYPERPLASIA).

Hereditary disorders of pyruvate metabolism. They are difficult to diagnose and describe because pyruvate is a key intermediate in glycolysis, gluconeogenesis, and the tricarboxylic acid cycle. Some inherited metabolic disorders may alter pyruvate metabolism indirectly. Disorders in pyruvate metabolism appear to lead to deficiencies in neurotransmitter synthesis and, consequently, to nervous system disorders.

Proteins secreted by the prostate gland. The major secretory proteins from the human prostate gland include PROSTATE-SPECIFIC ANTIGEN, prostate-specific acid phosphatase, prostate-specific membrane antigen, and prostate-specific protein-94.
