Brief Summary
This is a single center prospective imaging study investigating the utility of hyperpolarized 13C-pyruvate +/-13C,15N-Urea/ metabolic MR imaging. The current protocol will serve as a companion imaging biomarker study paired with standard of care (SOC) therapeutics, as well as investigational therapies that participants may be scheduled to receive outside of this protocol.

Outcome Measures
Primary Outcomes (3)
Signal-to-noise ratio (Part A)
Signal-to-noise ratios is defined as a MR/spectroscopy parameter, consisting of the HP C13-Pyruvate or Lactate signal (peak) relative to background noise level (baseline) in MRI spectra of the tissue. For the analysis and interpretation of the HP 13C-pyruvate MR imaging data, DICOM software package (SIVIC) will be used to align, display and quantitatively interrogate serial multi-parametric imaging data.
Day of imaging (1 day)
Mean percent change from baseline in intratumoral HP pyruvate/lactate ratio
Intra-tumoral region of interest (ROI) will be used to quantify peak HP lactate/pyruvate ratio values in the selected volumes of interest. Descriptive statistics will be used to characterize the mean change from baseline in intra-tumoral HP pyruvate/lactate ratio for the study cohort, along with a 95% confidence interval
Up to 25 days
Mean percent change from baseline in Urea Area Under Curve (AUC)
Intra-tumoral region of interest (ROI) will be used to quantify urea AUC. Descriptive statistics will be used to characterize the mean change from baseline in Urea Area Under Curve (AUC)
Up to 25 days
Secondary Outcomes (8)
Number of participants reporting adverse events (Part A)
Day of imaging (1 day)
Number of participants reporting adverse events (Part B)
Up to 6 months
Median percent change from baseline in peak intratumoral hyperpolarized lactate-to-pyruvate ratio (Part B)
Up to 6 months
Median percent change from baseline in intra-tumoral HP Urea AUC (Part B)
Up to 6 months
Objective response rate (ORR) (Part B)
Up to 6 months
- +3 more secondary outcomes
Study Arms (2)
Part A / Phase 1: Feasibility Run-In
EXPERIMENTALParticipants will undergo MR imaging at a single time point. Imaging will take one day and no follow up is planned.
Part B/ Phase II: Biomarker Cohort
EXPERIMENTALParticipants will undergo paired 13C-pyruvate +/- 13C,15N-urea/metabolic MR imaging at baseline and again after approximately 21 days of therapy. Duration of the intervention period is approximately 21 days, and participants will be followed until discontinuation of their current SOC treatment regimen, about 6 months.

Eligibility Criteria
You may qualify if:
- Presence of at least one target pelvic, abdominal, thoracic, neck or extremity lesion detected by standard staging scans that, in the judgment of study investigator, would be amenable to hyperpolarized C-13 pyruvate/metabolic MR imaging:
- a. Target lesion must measure at least 1.0 cm in long axis diameter on Computerized tomography (CT) or magnetic resonance imaging (MRI).
- The participant is able and willing to comply with study procedures and provide signed and dated informed consent.
- Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1.
- Adequate renal function defined as creatinine \< 1.5 x upper limit of normal (ULN) or estimated creatinine clearance \>50 mL/min (by the Cockcroft Gault equation).
- Participants age 18 and older.
- Part B only:
- Planned treatment for disease with either standard of care regimen or an investigational agent.
You may not qualify if:
- Patients who because of age, general medical or psychiatric condition, or physiologic status cannot give valid informed consent.
- Patients with contra- indications to MRI, such as cardiac pacemakers or non-compatible intracranial vascular clips.
- Patients with a metallic implant or device that distorts local magnetic field and compromises the quality of MR imaging.
- Patients with poorly controlled hypertension, defined as systolic blood pressure at study entry greater than 160mm Hg or diastolic blood pressure greater than 100mm Hg.
- Note: The addition of anti-hypertensives to control blood pressure is allowed.
- Patients with congestive heart failure or New York Heart Association (NYHA) status \>= 2.
- Patients who are pregnant or lactating.
- A history of clinically significant EKG abnormalities or myocardial infarction (MI) within 6 months of study entry.
- Note: Patients with rate-controlled atrial fibrillation/flutter will be allowed on study.
- Any condition that, in the opinion of the Principal Investigator,
