DNP-MRSI of HCC Metabolism to Predict Therapeutic Response

Prior treatment

• Prior LRT or systemic cancer therapy to the target lesion
• Contraindication to MRI including prior MRI contrast reaction
• Metallic implant within the liver
• Baseline systolic blood pressure \<90 mmHg or \>180 mmHg, or symptomatic orthostatic hypotension, measured within 1 hour prior to injection of hyperpolarized 1-13C-pyruvate
• Current use of high-dose beta-adrenergic antagonists (e.g., propranolol \> 160 mg/day, metoprolol \>200 mg/day, as these medications may impair compensatory tachycardia in response to pyruvate-induced vasodilation

Other illness

• Serious or unstable medical or psychological conditions that, in the opinion of the investigator, would compromise the subject's safety or successful participation in the study
• Congestive heart failure with New York Heart Association (NYHA) status ≥2

Lab values

• Females who are pregnant or breast feeding at the time of screening will not be eligible for this study. Females who are breast feeding are excluded because breast feeding is not recommended during the therapies which are included in the inclusion criteria for this study. For females with childbearing potential, a serum or urine pregnancy test will be performed within 1 day prior to the injection of \[1-13C\]-pyruvate in women of child-bearing potential. A lack of childbearing potential is defined as A) ≥50 years old, without menstrual activity for \>12 consecutive months, or B) Surgical sterilizations other than only tubal ligation. Females who do not meet the criteria defined in A, but have had tubal ligation, must still undergo pregnancy testing. Patient self-reporting the use of contraception, abstinence or same-sex partnership does not replace the need for pregnancy testing in women of childbearing potential
• A history of clinically significant EKG abnormalities, including QT prolongation, a family history of prolonged QT interval syndrome, or myocardial infarction (MI) within 6 months of study entry
• Estimated glomerular filtration rate (eGFR) \<30 mL/min/1.73 m2 within 28 days prior to contrast-enhanced MRI, unless patient is already on chronic dialysis

Other

• Inability to tolerate imaging procedures in the opinion of an investigator or treating physician including but not limited to the inability to lie still in the magnet for 1 hour and/or cooperate with breath holding instructions
• Decompensated cirrhosis (Child-Pugh C)

• Male or female, aged ≥ 18 years
• At least one HCC tumor meeting criteria for diagnosis of BCLC A, B or C HCC based on cross-sectional imaging as determined by a board-certified, sub-specialty trained radiologist
• Baseline systolic blood pressure \>90 mmHg or \<180 mmHg
• Signed and dated informed consent form
• Willingness to comply with all study procedures and availability for the duration of the study
