  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Adults receiving standard of care at University of California, San Francisco with biopsy-proven locally advanced or metastatic pancreatic ductal adenocarcinoma.

Who may be able to join

  • Participants must be 18 years or older.
  • Histological or cytological confirmation of pancreatic ductal adenocarcinoma (PDA).
  • Locally advanced or metastatic disease.
  • At least one target lesion in the abdomen measuring ≥ 1centimeter (cm), according to RECIST v1.1.
  • Eastern Cooperative Oncology Group (ECOG) Performance Status of 0, 1 or 2 (Karnofsky ≥ 50%)
  • Participants with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or endpoints of this study are eligible.
  • Ability to understand and willingness to sign a written informed consent document.

Who cannot join

  • Participants unwilling or unable to undergo magnetic resonance (MR) imaging, including patients with contra-indications to MRI, such as cardiac pacemakers or non-compatible intracranial vascular clips.
  • Poorly controlled hypertension, defined as either systolic > 170 or diastolic > 110. The addition of anti-hypertensives to control blood pressure is allowed for eligibility determination.
  • Congestive Heart Failure ≥ Class III.
  • Participants who are pregnant.
  • Individuals of childbearing potential must agree to undergo a urine pregnancy test prior to participating in the study scans. Pregnant individuals are excluded because there is an unknown but potential risk for adverse effects in the unborn child secondary to administration of HP 13C pyruvate to the study participant. A female is considered to not be of childbearing potential (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice), if they meet either of the following two criteria: (1) has reached a postmenopausal state (>= 12 continuous months of amenorrhea with no identified cause other than menopause); or (2) has undergone surgical sterilization (i.e., hysterectomy and/or bilateral oophorectomy for removal of uterus and/or ovaries).
  • Participants who are breastfeeding/chestfeeding. Breastfeeding/chestfeeding individuals are excluded because there is an unknown but potential risk for adverse effects in the unborn/nursing child secondary to administration of HP 13C pyruvate to the study participant. Breastfeeding/chestfeeding should be discontinued before administration of HP 13C pyruvate.
  • Known hypersensitivity to HP 13C pyruvate or any of its excipients.
  • Participants with any condition or social circumstance that, in the opinion of the investigator, would impair the participant's ability to comply with study procedures

About this study

Official title: Translating Hyperpolarized 13C MRI as a Novel Tool to Predict Treatment Response in Pancreatic Cancer

This study evaluates an investigational scan called hyperpolarized carbon-13 pyruvate magnetic resonance imaging (MRI) in assessing treatment response in patients with pancreatic ductal carcinoma (PDA) that has spread to nearby tissue or lymph nodes (locally advanced) or that has spread from where it first started (primary site) to other places in the body (metastatic). MRI is a standard scan that helps doctors see tumors, organs, tissue, and bone. Standard contrast agents (e.g., gadolinium) are sometimes used to help make the scan images brighter, or easier to see. Hyperpolarized carbon-13 pyruvate is an experimental contrast agent that is different from standard MRI contrast in that it provides information on how a tumor processes nutrients. Hyperpolarized carbon-13 pyruvate MRI scans may work better than MRI with standard contrast agents in predicting how PDA tumors respond to treatment.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine the percent changes in target tumor (primary tumor and/or abdominal metastases) hyperpolarized carbon C 13 pyruvate (HP 13C pyruvate) metabolism measures between the pre-treatment scan and the scan obtained 4 weeks (± 2 weeks) following treatment initiation. (Cohorts A and B).

II. To determine whether the changes in these metabolism measures are associated with best objective response (as defined by Response Evaluation Criteria in Solid Tumors [RECIST] version [v]1.1) on subsequent clinical computed tomography (CT) scans. (Cohorts A and B).

SECONDARY OBJECTIVES:

  1. In patients who proceed to surgery following neoadjuvant therapy (NAT), to determine whether the HP 13C pyruvate metabolism in the primary tumor on the pre-operative MRI or the change in HP 13C pyruvate metabolism are associated with pathological response. (Cohort B).

II. To examine models from the primary objective where multiple imputation is used for where only pre-treatment imaging is available. (Cohorts A and B).

EXPLORATORY OBJECTIVES:

  1. To determine whether the changes in target tumor (primary tumor and/or abdominal metastases) HP 13C pyruvate metabolism measures at 8 weeks (± 2 weeks) following treatment initiation are associated with best objective response as defined by RECIST v1.1 on subsequent clinical CT scans and clinical variables. (Cohort A).

II. To determine the repeatability of HP 13C pyruvate metabolism measures in the target tumor (primary tumor and/or abdominal metastasis) in patients with same-day repeated dose. (Cohorts A and B).

III. To compare the changes in HP 13C pyruvate metabolism measures to changes in tumor size and tumor apparent diffusion coefficients on the concurrently acquired 1H MRI. (Cohorts A and B).

IV. To determine whether the changes in target tumor (primary tumor and/or abdominal metastases) HP 13C pyruvate metabolism measures at 4 weeks (± 2 weeks) following treatment initiation (Cohorts A and B), 8 weeks (± 2 weeks) following treatment initiation (Cohort A), and after completion of NAT (Cohort B) are associated with progression-free survival (PFS) and overall survival (OS). (Cohorts A and B).

OUTLINE: Patients are assigned to 1 of 2 cohorts.

COHORT A: Patients with advanced/non-resectable pancreatic ductal carcinoma (PDA) receive HP 13C pyruvate intravenously (IV) and undergo MRI scans prior to receiving standard of care (SOC) treatment and again at 4 weeks after starting SOC treatment. Patients may optionally undergo an additional HP 13C pyruvate MRI scan at 8 weeks after starting SOC treatment. Patients who have excellent response and deemed candidates for surgical resection may be switched to Cohort B.

COHORT B: Patients with localized PDA who are deemed candidates for NAT receive HP 13C pyruvate IV and undergo MRI scans prior to starting NAT and again at 4 weeks after starting NAT. Patients may optionally undergo an additional HP 13C pyruvate MRI scan at 8 weeks after starting NAT. Patients who develop rapidly progressive disease and are deemed non-resectable may be switched to Cohort A.

Patients in both cohorts also undergo CT and additional MRI scans throughout the study.
