Targeting Pancreatic Cancer With Sodium Glucose Transporter 2 (SGLT2) Inhibition

• Histologically or cytologically confirmed metastatic or locally advanced pancreatic ductal adenocarcinoma, pancreatic adenosquamous carcinoma or squamous cell carcinoma
• Patients with treated/stable brain metastases, defined as patients who have received prior therapy for their brain metastases and whose CNS disease is radiographically stable at study entry, are eligible.
• Measurable disease defined as lesions that can be accurately measured in at least one dimension (longest diameter to be recorded) as ≥ 10 mm with CT scan, as ≥ 20 mm by chest x-ray, or ≥ 10 mm with calipers by clinical exam.
• No prior systemic therapy for pancreatic ductal adenocarcinoma in the metastatic or locally advanced setting.
• Planning to receive treatment with nab-paclitaxel and gemcitabine.
• At least 18 years of age.
• ECOG performance status ≤ 1

• Normal bone marrow and organ function as defined below:

  • Leukocytes ≥ 3,000/mcL
  • Absolute neutrophil count ≥ 1,500/mcL
  • Platelets ≥ 100,000/mcL
  • Total bilirubin ≤ 1.5 x IULN
  • AST(SGOT)/ALT(SGPT) ≤ 3.0 x IULN
  • Estimated glomerular filtration rate eGFR ≥ 30 mL/min/1.73m\^2
• Because chemotherapeutic agents such as nab-paclitaxel and gemcitabine are known to be teratogenic, women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control, abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she must inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of the study, and at least one month after completion of the study
• Agreement to adhere to Lifestyle Considerations throughout study duration
• Ability to understand and willingness to sign an IRB approved written informed consent document (or that of legally authorized representative, if applicable).

Exclusion Criteria:

• History of total pancreatectomy
• Current or previous treatment with SGLT2i or thiazolidinedione.
• Currently receiving regularly scheduled systemic steroids in the form of prednisone or dexamethasone. Note that dexamethasone that can be prescribed for nausea on the day of chemotherapy, but in subsequent days will be replaced by a nonsteroidal anti-emetic for patients in this trial. Topical steroid ointments or creams for occasional skin rash is allowed.
• A history of other malignancy with the exceptions of malignancies for which all treatment was completed at least 2 years before registration with no evidence of disease and locally treated skin squamous or basal cell carcinoma.
• History of stroke or transient ischemic attack (in the last 5 years).
• HbA1c > 10% unless approved by endocrinologist
• Currently receiving any other investigational agents.
• A history of allergic reactions attributed to compounds of similar chemical or biologic composition to dapagliflozin, nab-paclitaxel, gemcitabine or other agents used in the study.
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, peripheral arterial disease, ketoacidosis, severe kidney disease (estimated glomerular filtration rate eGFR \< 30 mL/min/1.73m2), symptomatic hypotension, and chronic/frequent urinary tract infections or yeast infections.
• Pregnant and/or breastfeeding. Women of childbearing potential must have a negative pregnancy test within 14 days of study entry.
• Patients with HIV are eligible unless their CD4+ T-cell counts are \< 350 cells/mcL or they have a history of AIDS-defining opportunistic infection within the 12 months prior to registration. Concurrent treatment with effective ART according to DHHS treatment guidelines is recommended.
