About

This study is a randomized pilot/pharmacodynamic/genomic study of neoadjuvant paricalcitol to target the microenvironment in resectable pancreatic cancer to determine the effect of targeting the vitamin D metabolic program in the tumors of patients treated with one cycle of gemcitabine/abraxane with or without paricalcitol prior to surgery for resectable pancreatic cancer through an assessment of cellular and imaging markers.

Inclusion and exclusion criteria

Inclusion Criteria

  • Previously untreated, apparently resectable, adenocarcinoma of the pancreas at registration.
  • Age greater than or equal to 18 years
  • Eastern Cooperative Oncology Group performance status of 0-2.
  • Standard laboratory criteria for hematologic, biochemical, and urinary indices within a range that, in the opinion of the physician, clinically supports enrollment of the patient on the trial. Note: subjects must have: Creatinine < 2x Upper Normal Limit , Transaminases < 3x Upper Normal Limit, Neutrophils >1.5x109/L, and Platelets >100,000/mm3
  • Ability to provide written informed consent

Exclusion Criteria

  • Patients with hypercalcemia (blood levels greater than 11.5 mg/dL; in patients with kidney disease, blood calcium levels must be 9.5 mg/dL or lower before starting paricalcitol).
  • Patients who are currently pregnant, planning to become pregnant, or breast-feeding.
  • Patients who, in the opinion of the physician, would not be clinically appropriate for receipt of the therapy regimen associated with participation

Subject will receive gemcitabine/abraxane with preoperatively paricalcitol. Patients randomized to receive paricalcitol pre-operatively will begin treatment with intravenous paricalcitol at 25 μg three times weekly for one cycle beginning day 1 of therapy until the day before surgery (+/- 3 days).
Treatment:
Drug: Gemcitabine
Drug: Paricalcitol
Drug: Abraxane
No Pre-operative Paricalcitol
Active Comparator group

Treatment:
Drug: Gemcitabine
Drug: Abraxane
