Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Pre-operative Paricalcitol

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).

Group Type EXPERIMENTAL

Paricalcitol

Intervention Type DRUG

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).

Abraxane

Intervention Type DRUG

Dose: 125mg/m2 Route: IV infusion over 30 minutes Frequency (within a 28 day cycle): Day 1, 8, 15

Gemcitabine

Intervention Type DRUG

Dose: 1000mg/m2 Route: IV infusion over 30-100 minutes Frequency (within a 28 day cycle): Day 1, 8, 15

No Pre-operative Paricalcitol

Subject will receive gemcitabine/abraxane without paricalcitol preoperatively.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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
