This phase I trial studies the best dose and side effects of mesenchymal stromal cells-derived exosomes with KrasG12D siRNA (iExosomes) in treating participants with pancreatic cancer with KrasG12D mutation that has spread to other places in the body. iExosomes may work better at treating pancreatic cancer.
Patients with histologically confirmed metastatic pancreatic ductal adenocarcinoma harboring KrasG12D mutation
Patients must have documented progression or stable disease on one or more lines of systemic therapy. If stable disease, patient must have completed at least 4 months of chemotherapy with cytotoxic therapy
KrasG12D mutation status will be informed from any previous routine molecular profiling (using commercial assays such as Foundation One, Caris, Oncomine or other) of tissue or blood. Additional KrasG12D mutation status may be confirmed using tissue biopsy or blood prior to enrolling into the trial
ECOG (Eastern Cooperative Oncology Group) performance status of 0-1
Concurrent severe and/or uncontrolled medical conditions which could compromise participation in the study such as unstable angina, myocardial infarction within 6 months, unstable symptomatic arrhythmia, uncontrolled diabetes, serious active or uncontrolled infection
Pregnancy (positive pregnancy test) or lactation
Known CNS (central nervous system) disease, except for treated brain metastasis. Treated brain metastases are defined as having no evidence of progression or hemorrhage after treatment and no ongoing requirement for dexamethasone, as ascertained by clinical examination and brain imaging (magnetic resonance imaging-MRI or computerized tomography-CT) during the screening period. Anticonvulsants (stable dose) are allowed. Treatment for brain metastases may include whole brain radiotherapy (WBRT), radiosurgery (RS; gamma knife, linear accelerator [LINAC], or equivalent) or a combination as deemed appropriate by the treating physician. Patients with CNS metastases treated by neurosurgical resection or brain biopsy performed within 3 months prior to day 1 will be excluded
