Brief Summary

This phase II trial investigates how well paricalcitol and hydroxychloroquine work when combined with gemcitabine and nab-paclitaxel in treating patients with pancreatic cancer that has spread to other places in the body (advanced or metastatic). Paricalcitol (a form of vitamin D) works by blocking a signal in the cancer cells that leads to growth and spreading of the tumor. Hydroxychloroquine (an autophagy inhibitor) enhances the activity of standard chemotherapy on cancer cells and prevent them to utilize energy to grow. Chemotherapy drugs, such as gemcitabine and nab-paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving paricalcitol and hydroxychloroquine together with standard chemotherapy (gemcitabine and nab-paclitaxel) may work better in treating patients with pancreatic cancer compared to either paricalcitol or hydroxychloroquine alone.

Detailed Description

PRIMARY OBJECTIVE:

I. To evaluate the anti-tumor activity of the combination of paricalcitol plus hydroxychloroquine (PH) when added to gemcitabine and nab-paclitaxel treatment by assessing the overall response rate (ORR) by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.

SECONDARY OBJECTIVES:

I. To evaluate the safety and tolerability of the combination of paricalcitol plus hydroxychloroquine (PH) when added to gemcitabine and nab-paclitaxel treatment in patients with advanced pancreatic cancer.

II. To evaluate the anti-tumor activity of the combination of paricalcitol plus hydroxychloroquine (PH) when added to gemcitabine and nab-paclitaxel treatment by assessing progression-free survival (PFS) and overall survival (OS).

TERTIARY/EXPLORATORY OBJECTIVES:

I. Evaluate the effects of PH on cancer-associated fibroblasts (CAF) and immune cells using mass cytometry (CyTOF) to characterize the presence and distribution of these cells.

II. Multiplex immunohistochemistry (IHC) to evaluate these pathways including TGF-beta1, TGF-beta1 RII, SMAD4, LC3 in addition to markers of fibrosis (collagen) and tumor (cytokeratin).

OUTLINE:

Beginning day -14, patients receive paricalcitol intravenously (IV) three times weekly and hydroxychloroquine orally (PO) twice daily (BID). Patients also receive gemcitabine IV over 30 minutes and nab-paclitaxel IV over 30 minutes on days 1, 8, 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 28 days and every 12 weeks thereafter.

Eligibility Criteria

Inclusion Criteria

• Patients must have histologically confirmed advanced or metastatic adenocarcinoma of the pancreas (stage IV)
• Patients must have measurable disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST) criteria 1.1 as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded as >= 10 mm (>= 1 cm) on computed tomography (CT) scan, magnetic resonance imaging (MRI)
• Patients may have had prior neoadjuvant or adjuvant treatment for pancreatic cancer. The last dose of chemotherapy must have been 12 months prior to study entry. No prior systemic therapy for metastatic disease
• Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)
• Hemoglobin >= 9.0 g/dl (no transfusions allowed within 7 days of cycle 1 day 1 to meet entry criteria) (within 28 days of cycle 1 day 1)
• Absolute neutrophil count (ANC) >= 1,500/mcL (after at least 7 days without growth factor support or transfusion) (within 28 days of cycle 1 day 1)
• Platelets >= 100,000/mcL (no transfusions allowed within 7 days of cycle 1 day 1 to meet entry criteria) (within 28 days of cycle 1 day 1)
• International normalized ratio (INR) =< 1.5 (within 28 days of cycle 1 day 1)
• Partial thromboplastin time (PTT) < 1.5 x upper limits of normal (ULN) (within 28 days of cycle 1 day 1)
• Total bilirubin =< 1.5 times the institutional upper limit of normal (ULN) (within 28 days of cycle 1 day 1)
• Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) =< 5.0 times the ULN (within 28 days of cycle 1 day 1)
• Serum creatinine =< 1.5× ULN or creatinine clearance >= 60 mL/min/1.73 m^2 for patients with creatinine levels > 1.5 x ULN. Creatinine clearance should be calculated per institutional standard (within 28 days of cycle 1 day 1)
• Calcium (corrected for albumin) =< 1 x institutional upper limit of normal (within 28 days of cycle 1 day 1)
• Patients with prior radiotherapy are acceptable. It must be at least 21 days since administration of radiation therapy and all signs of toxicity must have abated
• Patient must have a primary or metastatic non-bone site that is amenable to safe biopsy. Bone only lesions are not suitable for biopsy
• Patients with known G6PD deficiency, severe psoriasis, porphyria, macular degeneration or severe diabetic retinopathy are ineligible because of the potential for greater hydroxychloroquine (HCQ) toxicity
