artery, Borderline resectable: Interface between tumor and vessel measuring less
than 180º of the circumference of the vessel wall, Locally advanced (Not
Eligible): Encased (>180°)
- Vessel: Celiac axis, Resectable: No extension, Borderline resectable: Interface
between tumor and vessel measuring less than 180º of the circumference of the
vessel wall, Locally advanced (Not Eligible): Encased and no technical option for
reconstruction usually because of extension to the celiac axis/ splenic/left
gastric junction or the celiac origin
- Vessel: Common hepatic artery, Resectable: No extension, Borderline resectable:
Reconstructable§, short-segment interface between tumor and vessel of any degree,
Locally advanced (Not Eligible): Encased and no technical option for
reconstruction usually because of extension to the celiac axis/ splenic/left
gastric junction or the celiac origin Vessel: SMV/PV, Resectable: Patent,
Borderline resectable:SMV/PV Patent Interface between tumor and vessel measuring
180º or greater of the circumference of the vessel wall, and/or reconstructable§
occlusion Occluded and no technical option for reconstruction, Locally advanced
(Not Eligible): Occluded and no technical option for reconstruction
- Referenced from: Varadhachary et al., 2006(6) and Katz et al, 2013 (8). SMA,
superior mesenteric artery; SMV/PV, superior mesenteric vein/portal vein.
- Normal vein or artery proximal and distal to the site of suggested
tumor-vessel involvement suitable for vascular reconstruction
- In subjects requiring biliary decompression, biliary stent or drainage using
percutaneous transhepatic cholangiogram (PTC) are allowed.
- Participants must be =18 years of age at the time of enrollment.
- Participants must have an ECOG performance status 0-1 (see Appendix A).
- Participants must have adequate organ and marrow function as defined as:
- Absolute neutrophil count =1,500/mcL
- Platelets =100,000/mcL
- Total bilirubin =1.5 × institutional upper limit of normal
- AST(SGOT)/ALT(SGPT) =2.5 × institutional upper limit of normal
- Creatinine =1.5 × institutional upper limit of normal OR
- Creatinine clearance =60 mL/min/1.73 m2 for participants with creatinine levels
above 1.5 × upper limit of normal. Creatinine clearance can be calculated per
institutional standard.
- Female subjects of childbearing potential should have a negative urine or serum
pregnancy within 72 hours prior to receiving the first dose of study medication. If
the urine test is positive or cannot be confirmed as negative, a serum pregnancy test
will be required. Female subjects of childbearing potential should be willing to use 2
methods of birth control or be surgically sterile or abstain from heterosexual
activity for the course of the study through 9 months after the last dose of study
medication. Subjects of childbearing potential are those who have not been surgically
sterilized or have not been free from menses for > 1 year.
- Male subjects should agree to use an adequate method of contraception starting with
the first dose of study therapy through 6 months after the last dose of study therapy.
- Ability to understand and the willingness to sign a written informed consent document.
Exclusion Criteria:
- Has locally advanced or metastatic disease as determined by CT scan or MRI.
- Tumors with histologic features in addition to an adenocarcinoma component are
excluded. Variant histologies include but are not limited to adenosquamous, squamous,
neuroendocrine, undifferentiated with osteoclast like giant cells, acinar, hepatoid,
medullary carcinomas.
- Has either had any prior chemotherapy or targeted small molecule therapy, or
immunotherapy or radiation therapy for pancreatic cancer.
Note: If subject received major surgery for reason other than pancreatic cancer they must
have recovered adequately from the toxicity and/or complications from the intervention
prior to starting therapy.
- Has a known prior or current synchronous malignancy, except:
- Malignancy that was treated with curative intent and for which there has been no
known active disease for >5 years prior to enrollment
- Curatively treated non-melanoma skin cancer, cervical cancer in situ or prostatic
intraepithelial neoplasia, without evidence of prostate cancer.
- Significant history of uncontrolled cardiac disease defined as uncontrolled
hypertension (defined by a systolic BP >=160 mm Hg and/or diastolic BP >= 100mm Hg),
unstable angina, myocardial infarction within the last 4 months, or uncontrolled
congestive heart failure. Subjects with a history of cardiac disease should have a
clinical risk assessment of cardiac function using the New York Heart Association
Functional Classification. To be eligible for this trial, participants should be class
2B or better.
- Has a medical history or current diagnosis of myocarditis.
- Has a left ventricular ejection fraction <50%, cardiac valvulopathy > grade 2, or
elevated cardiac enzymes (troponin I) elevation > 2x ULN.
- Has a condition/s that are considered to have a high risk of clinically significant GI
bleed or any other condition associated with or history of significant bleeding.
- Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any
other form of immunosuppressive therapy within 7 days prior to the first dose of trial
treatment. Patients receiving physiological replacement doses of corticosteroids (10mg
of prednisone or equivalent) are allowed.
- Has known active, uncontrolled HIV (high viral load), Hepatitis B (e.g., HBsAg
reactive) or Hepatitis C (e.g., HCV RNA [qualitative] is detected).
- Patients who have been vaccinated for hepatitis B and do not have a history of
infection are eligible.
- Has received a live vaccine within 30 days prior to the first dose of trial treatment.
COVID-19 vaccination or booster is permitted any time prior to enrollment or during
treatment on trial, in a manner consistent with individual institutional guidelines.
- Has an active autoimmune disease requiring systemic treatment within the past 3 months
or a documented history of clinically severe autoimmune disease, or a syndrome that
requires systemic steroids or immunosuppressive agents. Subjects with vitiligo or
resolved childhood asthma/atopy would be an exception to this rule. Subjects that
require intermittent use of bronchodilators or local steroid injections would not be
excluded from the study. Subjects with hypothyroidism stable on hormone replacement or
Sjorgen's syndrome will not be excluded from the study.
- Has an active serious infection requiring systemic therapy.
- Has known psychiatric or substance abuse disorders that would interfere with
cooperation with the requirements of the trial.
- Subject is unable or unwilling to participate in a study related procedure.
- Is pregnant or breastfeeding or expecting to conceive or father children within the
projected duration of the trial, starting with the pre-screening or screening visit
