Brief Summary
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.

Pre-operative Paricalcitol
EXPERIMENTALSubject 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).
No Pre-operative Paricalcitol
ACTIVE COMPARATORSubject will receive gemcitabine/abraxane without paricalcitol preoperatively.
Interventions
Dose: 25 micrograms Route: IV Frequency (within a 28 day cycle):Three times weekly for one cycle beginning day 1 of therapy until the day before surgery (+/- 3 days) (for subjects randomized to receive paricalcitol), then three times weekly for 3 cycles post-operatively (for all subjects).
Dose: 125mg/m2 Route: IV infusion over 30 minutes Frequency (within a 28 day cycle): Day 1, 8, 15
Dose: 1000mg/m2 Route: IV infusion over 30-100 minutes Frequency (within a 28 day cycle): Day 1, 8, 15
Eligibility Criteria
You may qualify if:
- 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
You may not qualify if:
- 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
