NCT03581500

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).

Study Arms (1)

Diagnostic (hyperpolarized carbon C 13 pyruvate MRSI)

EXPERIMENTAL

Patients receive hyperpolarized carbon C 13 pyruvate IV over 10-20 seconds and undergo MRSI over 2-3 minutes at 6 and 8 weeks.

Eligibility Criteria

Sexmale
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • 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

You may not qualify if:

  • 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
