About this study
Official title: Pilot Study Using Hyperpolarized 13C-Pyruvate Magnetic Resonance Spectroscopic Imaging in Patients With Pancreatic Cysts Undergoing Surgical Resection
To learn if Hyperpolarized C-Pyruvate Magnetic Resonance (HP-MR) Spectroscopic Imaging can help doctors detect low-risk (benign) and high-risk (malignant) cysts.
Read the detailed description
Primary Objectives:
To explore the use of HP-MR in patients with cystic lesions of the pancreas undergoing surgical resection. Patients will undergo HP-MR prior to surgical resection (or cyst wall biopsy) and kpl values will be determined to evaluate metabolic activity. Pathology will then determine whether the cyst was of benign/low risk or malignant/high risk nature. The ability for increased kpl to detect an invasive carcinoma will be explored by estimating the association between lesions' kpl values and lesions' pathological results.
Secondary Objectives:
- A kpl inflection point, or threshold, will then be explored to estimate the association with malignant/high risk cyst. This threshold value would then undergo further validation in future studies to calculate the sensitivity and specificity of this value.
- Correlate HP-MR findings to tissue metabolomics (ex vivo): In all patients who undergo surgical resection, a small surgical sample will be supplied for ex vivo metabolomics. NMR metabolomics will be used to measure lactate, creatine, choline, phosphocholine, glycerophosphocholine, and alanine within the tissue sample. The highest lactate levels should be found in the most aggressive tumors, which also should correlate to high kpl.
- Correlate HP-MR findings to blood and cyst fluid biomarkers: Blood samples taken prior to surgical resection will be analyzed for CA19-9 and CEA. If the patient has a cystic fluid aspiration prior to surgical resection, then CA19-9, amylase and CEA will also be measured in these samples. These biomarkers will be compared to findings from HP-MR and pathologic results.
- Correlate HP-MR findings to immunohistochemical staining for LDH-A and HIF-1α: Tissue taken from pathology samples for metabolomics will also undergo immunohistochemical staining for LDH-A and HIF-1α.
- Correlate gut and tissue microbiome with HP-MR findings: Microbiome studies may be performed under the auspice of another protocol but could be analyzed under this protocol in relation to HP-MR findings. PA 16-0911 allows for the collection of stool in patients with cysts of the pancreas for gut microbiome investigation in relation to the development of pancreatic cancer.
- To explore the safety and tolerability of HP-MR in patients with cystic lesions of the pancreas undergoing surgical resection or cyst wall biopsy.

Given by Injection
| Study group | Role | What they receive |
|---|---|---|
| Hyperpolarized 13C-Pyruvate Magnetic Resonance Spectroscopic Imaging | Experimental | Participants will have the HP-MR scan within the 4 weeks before your scheduled surgery.
Hyperpolarized C-Pyruvate will be injected by vein during the scan. Your vital signs (temperature, blood pressure, heart rate and respiration [breathing]) will be monitored during the scan. The estimated time of the scan is a couple of minutes, but you may be in the room of the MRI for up to 30 minutes for preparation. The entire process of obtaining the MRI (and possible blood draw) may be up to half of a work day (not including your personal travel time). Receives: Drug: Hyperpolarized 13-C-pyruvate |

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Hyperpolarized 13-C-pyruvate in people with Pancreatic Cyst, run by M.D. Anderson Cancer Center at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: paused, as of the sponsor's last update on 13 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of Adverse Events, Graded According to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version (v) 5.0 (time frame: Through study completion; an average of 1 year.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Aug 2026.
