Overview

This is a Pilot/Phase I clinical study of hyperpolarized 13C (HP 13C) pyruvate injection that includes the acquisition of magnetic resonance (MR) data performed on participants with meningioma to evaluate metabolism and aid in the non-invasive characterization of aggressive tumor behavior

Primary Objective: I. To assess the feasibility of hyperpolarized 13C MR imaging as a new and unique tool in the characterization of aggressive tumor behavior in participants with meningioma. Secondary Objectives: I. To define the most appropriate parameters for obtaining hyperpolarized 13C data from meningioma patients with a run-in study to optimize spatial and temporal resolution and coverage by detecting signal amplitudes and time dynamics. II. To measure tumor pyruvate-to-lactate, pyruvate-to-alanine, and pyruvate-to-bicarbonate conversion by 13C pyruvate MR imaging in participants with meningioma planning to undergo surgical resection within 4 weeks, using parameters. Outline: Participants will receive a single imaging procedure using HP 13C pyruvate. Participants will then be followed-up for 30 days after completion of the study or until voluntary withdrawal or death.

Inclusion Criteria: 1. Known (histopathologically confirmed) or presumed meningioma based on imaging with measurable disease on MRI that shows gadolinium enhancement (at least one cm diameter) intracranially (e.g., not confined to skull base alone). a. Thirty of the participants plan to have surgical resection within 4 weeks 2. Participants cannot have contraindication to MRI examinations. 3. Age \>=18 years. 4. Have a life expectancy of \>12 weeks. 5. Karnofsky Performance Status \> 60%. 6. Participants must have adequate renal function (creatinine \< 1.5 mg/dL) before imaging. This test must be performed within 60 days prior to hyperpolarized imaging scan. 7. Participants must sign an informed consent indicating that they are aware of the investigational nature of this study. 8. Participants must sign an authorization for the release of their protected health information. Exclusion Criteria: 1. Has any significant medical illnesses that in the investigator's opinion cannot be adequately controlled with appropriate therapy, would compromise the patient's ability to participate in this study or any disease that will obscure toxicity or dangerously impact response to the imaging agent. 2. Uncontrolled blood pressure (Systolic BP≥140 mmHg or diastolic BP ≥\>=90 mmHg) despite an optimized regimen of antihypertensive medication. 3. Has a history of any other cancer (except non-melanoma skin cancer or carcinoma in-situ of the cervix), unless in complete remission and off of all therapy for that disease for a minimum of 3 years. 4. Participants must not be pregnant or breast feeding. Women of childbearing potential are required to obtain a negative pregnancy test within 14 days of Hyperpolarized Imaging scan. Effective contraception (men and women) must be used in participants of child-bearing potential. 5. Participants must be excluded from participating in the study if they are not able to comply with the study and/or follow-up procedures.

Outcomes

Primary Outcomes

Proportion of participants who complete 13C pyruvate MR imaging.

All participants who are enrolled in the study and receive any amount of hyperpolarized 13C pyruvate will be included in the primary outcome analysis. The proportion of participants who complete hyperpolarized 13C pyruvate MR imaging will be reported. If the proportion is greater than 0.7, hyperpolarized 13C MR imaging will be determined to be feasible.
