Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
I. To determine the kPL (metabolic flux from hyperpolarized \[HP\] \[1-13C\]pyruvate to \[1-13C\]lactate) and kPG (metabolic flux from HP \[2-13C\]pyruvate to \[5-13C\]glutamate) within target lesion. (Cohort A) II. To determine the mean percent change from baseline in intra-tumoral kPL and kPG within target lesion. (Cohort B)
SECONDARY OBJECTIVE:
I. To descriptively report on the intra-tumor heterogeneity in kPL and kPG measurement within target lesion. (Cohorts A and B)
EXPLORATORY (CORRELATIVE) OBJECTIVES:
I. To determine if the change from baseline in kPL and kPG is associated with subsequent clinical outcomes on treatment including prostate specific antigen (PSA) response rate and radiographic progression-survival by Prostate Cancer Working Group 3 (PCWG3) criteria. (Cohort B) II. In target lesions that are measurable by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria, to determine whether baseline and/or change from baseline in intratumoral kPL and kPG is associated with subsequent objective response by RECIST criteria. (Cohort B) III. To determine the mean percent change from baseline in peak intra- tumoral HP lactate (lac)/pyruvate (pyr) and glutamate (glu)/pyr ratios on repeat metabolic magnetic resonance imaging (MRI) obtained at the time of radiographic disease progression by PCWG3 criteria. (Cohort B) IV. To investigate for association between HP kPL and kPG as well as area under the curve (AUC) lac/pyr and glu/pyr ratios with tissue- based markers of elevated lactate and glutamate metabolism including MYC and Lactate dehydrogenase A (LDHA) and Pyruvate dehydrogenase (PDH) protein expression. (In participants who undergo optional tumor biopsy \[Cohort A or B\]) V. To investigate for an association between HP kPL and kPG as well as area under the curve (AUC) lac/pyr and glu/pyr ratios with histologic evidence of small cell/neuroendocrine differentiation. (In participants who undergo optional tumor biopsy (Cohort A or B))
OUTLINE: Patients are assigned to 1 of 2 cohorts.
COHORT A (SINGLE TIME-POINT): Patients receive C-1 labeled hyperpolarized carbon C 13 pyruvate intravenously (IV) over less than 1 minute then undergo magnetic resonance spectroscopic imaging (MRSI) over less than 5 minutes. Patients may also receive an optional C-2 labeled hyperpolarized carbon C 13 pyruvate IV and undergo MRSI within 15-60 minutes following completion of the first scan.
COHORT B (MULTIPLE TIME-POINT): Patients receive C-1 labeled hyperpolarized carbon C 13 pyruvate IV over less than 1 minute then undergo MRSI over less than 5 minutes. Patients may also receive an optional C-2 labeled hyperpolarized carbon C 13 pyruvate IV and undergo MRSI within 15-60 minutes following completion of the first scan at baseline and 12 weeks.
After completion of study treatment, patients are followed up periodically.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Cohort A: Hyperpolarized C13 MRI at a single time point
Participants will undergo MR imaging with hyperpolarized 13C pyruvate of a pre-selected target lesion at a single time point and will receive up to two 13C pyruvate (C-1 and C-2 labeled 13C pyruvate) investigational medicinal product (IMP) injections on the day of imaging (2nd injection is optional), as well as optional MR- or CT- guided tumor biopsies at baseline and at the time of disease progression following completion of HP C-13 MRI at the corresponding time point
Hyperpolarized C13
Given by intravenous injection. When receiving two HP 13C pyruvate injections, the injections will be separated by a period of 15-60 minutes
Magnetic Resonance Imaging (MRI)
Magnetic resonance imaging (MRI) is a medical imaging technique that uses a magnetic field and computer-generated radio waves to create detailed images of the organs and tissues in your body
Cohort B: Hyperpolarized C13 MRI at multiple time points
Participants will undergo hyperpolarized (HP) C13 MRI at baseline and 12 weeks (+/- 8 weeks). Participants in Cohort B may undergo additional optional MR imaging at the time of disease progression. the same sequence of injections (C-1 labeled pyruvate first, C-2 labeled pyruvate second) will be used for subsequent scan time points as well.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Presence of at least one target lesion detected by standard staging scans that, in the judgment of Study Investigators, would be amenable to hyperpolarized C-13 pyruvate/metabolic MR imaging:
1. Soft tissue/visceral organ target lesions must measure at 1 cm in long axis diameter on CT or MRI.
2. Target lesions in the bone must be visualized by CT or MRI (lesions present only on bone scan do not qualify).
3. For patients with target lesion in prostate/prostatic bed:
i. No contra-indications to endorectal coil insertion (e.g., patients with a prior abdominoperineal resection of the rectum or latex allergy).
ii. No prior local treatment to the selected lesion, or evidence of radiographic progression following prior local therapy to selected lesion.
3. Able and willing to comply with study procedures and provide signed and dated informed consent.
4. Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
5. For patients undergoing optional tumor biopsy:
1. No history of bleeding diathesis.
2. Patients on anti-coagulation they must be able to safely stop treatment for purposes of tumor biopsy.
Exclusion Criteria
2. Patients unwilling or unable to undergo MR imaging, including patients with contra- indications to MRI, such as cardiac pacemakers or non-compatible intracranial vascular clips.
3. Metallic hip implant or any other metallic implant or device that distorts local magnetic field and compromises the quality of MRI.
4. Any condition that, in the opinion of the Principal Investigator, would impair the patient's ability to comply with study procedures
