Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person’s general health condition or prior treatments.

Ages Eligible for Study:
ALL

Sexes Eligible for Study:
18 Years

Accepts Healthy Volunteers:

Ability to understand and the willingness to sign a written informed consent document
Age >= 18 years
Eastern Cooperative Oncology Group (ECOG) performance status of 0-2
Clinically-confirmed diagnosis of resectable, borderline resectable, locally-advanced or metastatic adenocarcinoma of the pancreas.

Patients with disease that is eligible for curative surgery may not be eligible for all study arms.
Participants may be treatment naïve or have received prior therapy for the treatment of their pancreatic ductal adenocarcinoma (PDAC). A minimum washout period of 10-days after completing the most recent line of therapy is required before a participant can initiate treatment with study agent(s)
Based on available imaging, participant must have at least one disease lesion that can be biopsied in accordance with institutional standards
Hemoglobin >= 9.0 g/dL with no blood transfusion within 28 days of starting treatment (within 4 weeks prior to initiating window treatment). Note: laboratory tests performed after initial screening (but still within the screening window) will be evaluated by the investigator; should any of these values fall outside eligibility parameters, the patient may still be eligible per investigator discretion
White blood cells (WBC) > 3 x 10^9/L (within 4 weeks prior to initiating window treatment). Note: laboratory tests performed after initial screening (but still within the screening window) will be evaluated by the investigator; should any of these values fall outside eligibility parameters, the patient may still be eligible per investigator discretion
Absolute neutrophil count (ANC) >= 1.5 x 10^9/L (> 1500 per mm^3) (within 4 weeks prior to initiating window treatment). Note: laboratory tests performed after initial screening (but still within the screening window) will be evaluated by the investigator; should any of these values fall outside eligibility parameters, the patient may still be eligible per investigator discretion.

May be waived on a case-by-case basis for patient populations recognized to have normal baseline values below this level
Platelet count >= 100 x 10^9/L (> 100,000 per mm^3) (within 4 weeks prior to initiating window treatment). Note: laboratory tests performed after initial screening (but still within the screening window) will be evaluated by the investigator; should any of these values fall outside eligibility parameters, the patient may still be eligible per investigator discretion

Note: laboratory tests performed after initial screening (but still within the screening window) will be evaluated by the investigator; should any of these values fall outside eligibility parameters, the patient may still be eligible per investigator discretion.

Creatinine clearance should be calculated per institutional standard. For participants with a baseline calculated creatinine clearance below normal institutional laboratory values, a measured baseline creatinine clearance should be determined. Individuals with higher values felt to be consistent with inborn errors of metabolism will be considered on a case-by-case basis
