Namodenoson treatment for advanced pancreatic cancer

Inclusion Criteria:

1. Males and females at least 18 years of age.
2. Histologically or cytologically confirmed pancreatic adenocarcinoma, or clinically diagnosed based upon scan results and a serum Cancer Antigen 19-9 value \>1000 U/mL on at least 1 occasion.
3. Pancreatic adenocarcinoma is advanced (i.e., treatment-refractory or metastatic) and no standard therapies are expected to be curative.
4. Pancreatic adenocarcinoma has progressed on at least 1 prior systemic treatment regimen, or the patient refuses standard treatment.
5. Prior pancreatic adenocarcinoma treatment was discontinued for at least 14 days prior to the Baseline Visit.
6. Measurable or evaluable disease by RECIST v1.1.
7. Patients with a history of treated central nervous system (CNS) metastases are eligible, provided they meet all of the following criteria: disease outside the CNS is present; there is no evidence of interim progression between the completion of CNS-directed therapy and the screening radiographic study; and there is no history of intracranial hemorrhage or spinal cord hemorrhage.
8. Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of ≤ 2.
9. The following laboratory values must be documented prior to the first dose of study drug:

   * Absolute neutrophil count (ANC) ≥1.5 × 109/L
   * Platelet count ≥50 × 109/L
   * Creatinine clearance ≥50 mL/min (estimated glomerular filtration rate by the Cockcroft-Gault) or serum creatinine ≤2.0 mg/dL
   * Aspartate aminotransferase (AST) and Alanine transaminase (ALT) ≤10X the upper limit of normal
   * Total bilirubin ≤10 mg/dL
   * Serum albumin ≥2.0 g/dL.
10. Life expectancy of ≥8 weeks.
11. For women of childbearing potential, negative serum pregnancy test result.
12. Provide written informed consent to participate.
13. Willing to comply with scheduled visits, treatment plans, laboratory assessments, and other trial-related procedures

Exclusion Criteria:

1. Receipt of systemic cancer therapy within 14 days prior to the Baseline Visit or concurrently during the trial.
2. Persistent toxicity ≥Grade 2 from previous cancer therapy, with the exceptions of alopecia and Grade 3 peripheral neuropathy.
3. Major surgery or radiation therapy within 14 days prior to the Baseline Visit.
4. Use of any investigational agent within the shorter of 4 weeks or 5 half-lives prior to the Baseline Visit.
5. Concomitant use of P-glycoprotein (P-gp)/breast cancer resistance protein (BCRP) inhibitors and/or substrates with a narrow therapeutic index unless the medication can be taken at least 3 hours before or after taking the investigational product.
6. Unable to swallow orally administered medication or presence of a gastrointestinal disorder likely to interfere with absorption of the study medication.
7. Uncontrolled or clinically unstable thyroid disease, per judgment of the Principal Investigator.
8. Active bacterial, viral, or fungal infection requiring systemic therapy or operative or radiological intervention.
9. Known human immunodeficiency virus- or acquired immunodeficiency syndrome-related illness or other immunodeficiency.
10. Active second primary malignancy (other than pancreatic adenocarcinoma) requiring treatment.
11. Uncontrolled arterial hypertension or congestive heart failure (New York Heart Association Classification 3 or 4).
12. Angina, myocardial infarction, cerebrovascular accident, coronary/peripheral artery bypass graft surgery, transient ischemic attack, or pulmonary embolism within 1 month prior to initiation of study drug.
13. History of, or ongoing, cardiac dysrhythmias requiring treatment, atrial fibrillation of any grade, or persistent prolongation of the corrected QT interval (QTc) (Fridericia) interval to \>470 msec \[mean of triplicate electrocardiogram measurements\] (patients with bundle branch block or a cardiac pacemaker will not be excluded for QTc reasons).
14. Pregnant or lactating female.
15. Women of childbearing potential, unless they agree to use dual contraceptive methods which, in the opinion of the Investigator, are effective and adequate for the patient's circumstances while on study drug and for at least 1 month thereafter.
16. Men who partner with a woman of childbearing potential, unless they agree to use effective, dual contraceptive methods (i.e., a condom, with female partner using oral, injectable, or barrier method) while on study drug and for 1 month afterward.
17. Any severe, acute, or chronic medical or psychiatric condition, or laboratory abnormality that may increase the risk associated with trial participation or study drug administration; may interfere with the informed consent process and/or with compliance with the requirements of the trial; or may interfere with the interpretation of trial results and, in the Investigator's opinion, would make the patient inappropriate for entry into this trial.
