Primary Outcome Measures:
  • Evaluate the safety and feasibility perioperative neoadjuvant zoledronic acid in patients with resectable pancreas cancer. [ Time Frame: 1 year postoperatively ] [ Designated as safety issue: Yes ]
    Rate of grade 3 and 4 toxicities, especially nephrotoxicity, electrolyte imbalance and osteonecrosis of the jaw.

  • Evaluate whether treatment with perioperative zoledronic acid prolongs overall survival or disease free survival. [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Determine the pharmacodynamics on selected immune cell subgroups in the peripheral blood and marrow by flow cytometric analysis. [ Time Frame: Marrow (prior to first dose of zoledronic acid and week 10), peripheral blood (prior to first dose of zoledronic acid, week 10, and month 6) ] [ Designated as safety issue: No ]
  • Determine the pharmacodynamics of neoadjuvant zoledronic acid therapy on selected immune cell subgroups in the tumor microenvironment by flow cytometric analysis of pancreatic tumor samples. [ Time Frame: Approximately week 2 (at time of surgery) ] [ Designated as safety issue: No ]
  • Determine the pharmacodynamics of neoadjuvant zoledronic acid therapy on the neoangiogenesis. [ Time Frame: Prior to zoledronic acid treatment and then completion of zoledronic acid treatment (approximately 10 weeks) ] [ Designated as safety issue: No ]
    Surrogate markers of tumor-associated neoangiogenesis will be analyzed by ELISA. Serum levels of VEGF and MMP9 will be measured compared pre and post treatment.

  • Determine the pharmacodynamics and surrogate markers neoangiogenesis analyzed by ELISA. [ Time Frame: Prior to zoledronic acid treatment and then completion of zoledronic acid treatment (approximately 10 weeks) ] [ Designated as safety issue: No ]
    Serum levels of VEGF and MMP9 will be measured compared pre and post treatment and the expression of VEGF and MMP9 in tumor samples will be analyzed.

  • Measure the presence and change of micrometastatic disease present in the bone marrow at the time of surgery versus baseline using immunohistochemistry. [ Time Frame: Baseline and week 2 (time of surgery) ] [ Designated as safety issue: No ]
  • Evaluate the clinical response and time to disease progression. [ Time Frame: 6 months postoperatively ] [ Designated as safety issue: No ]
  • Correlate the presence of micrometastatic disease with time to recurrence and outcome. [ Time Frame: 6 months postoperatively ] [ Designated as safety issue: No ]
  • Measure the change in the amount of micrometastatic disease from baseline. [ Time Frame: 6 months postoperatively ] [ Designated as safety issue: No ]
  • Determine the pharmacodynamics of neoadjuvant zoledronic acid therapy on selected immune cell subgroups in the hepatic metastatic niche by flow cytometric analysis of pancreatic tumor samples [ Time Frame: Approximately 2 weeks (time of surgery) ] [ Designated as safety issue: No ]

Primary Completion Date: April 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Neoadjuvant Zoledronic Acid

Zoledronic acid 4 mg IV prior to pancreatic resection (approximately 2 weeks prior to resection)

Pancreatic resection

Zoledronic acid 4 mg IV monthly for two additional doses

Drug: Zoledronic acid
Other Name: Zometa

Detailed Description:

Cancer of the pancreas carries an ominous prognosis. The five-year overall survival rate of this malignancy is less than 5%. Chemotherapy with gemcitabine carries a response rate of approximately 25%. Resection offers the only potential for cure; however, even with resection, the great majority of patients will die with metastatic disease. Substantial improvements are needed in the treatment of this malignancy.

Patients with this disease process have clearly developed a tolerance to their pancreatic tumor. This is evidenced by an increased number and activity immunosuppressive cells including MDSC and Treg in patients with pancreas cancer. An intervention that inhibits this population of MDSC and Treg may be highly useful in the treatment of this disease process.

A novel treatment of pancreas cancer, in this setting, would be to deplete circulating and tumor-associated immunosuppressive cells prior to resection. This would facilitate the host to mount a greater immune response against the tumor. The eventual goal would be to combine neoadjuvant zoledronic acid with gemcitabine, another agent which synergizes with zoledronic acid to target MDSC. When combined with current adjuvant chemoradiation, the use of zoledronic acid in the neoadjuvant and adjuvant setting, it is hoped that the patient could mount a greater immune response leading to increased overall survival through the prevention of local disease and distant metastasis.

Inclusion Criteria:

  • Patient must have a newly diagnosed, histologically or cytologically confirmed diagnosis of pancreatic adenocarcinoma. The histological slides or blocks must be available for review.
  • Patient must have resectable disease and be a candidate for surgical treatment.
  • Recent CT scan demonstrating pancreatic tumor, no evidence of distant disease, and no contraindication to resection.
  • Patients must be ≥ 18 years old.
  • Performance Status: Karnofsky Performance Status (KPS) ≥ 70
  • Life Expectancy > 12 weeks.
  • No previous history of chemotherapy for pancreas cancer prior to the start of protocol treatment.
  • Patients must have recovered from uncontrolled, intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris or cardiac arrhythmia.
  • Patients must have adequate bone marrow function defined as an absolute neutrophil count >1,500/mm3, platelet count >100,000/mm3 and hemoglobin >10 g/dl.
  • Patients must have normal renal function defined as serum creatinine ≤ 1.3 mg/dl or creatinine clearance ≥ 90 ml/min/1.73 m2 with a serum creatinine > 1.3 mg/dl.
  • Patients must have adequate hepatic function with total bilirubin < 5.0 mg/dl and AST ≤ 3x the institutional normal value.
  • Patient must have no prior or current active autoimmune disease requiring management with immunosuppression. This includes inflammatory bowel disease, systemic vasculitis, scleroderma, psoriasis, hemolytic anemia, immune-mediated thrombocytopenia, rheumatoid arthritis, systemic lupus erythematosus, Sjogren's syndrome, sarcoidosis or other rheumatologic disease. Asthma and chronic obstructive pulmonary disease that does not require daily systemic corticosteroids is acceptable.
  • The patient with previous history of malignancy is eligible for this study only if the patient meets the following criteria for cancer survivor: (i) patient has undergone potentially curative therapy for all prior malignancies; (ii) the patient has been considered disease free for at least 5 years; (iii) adequately treated non-melanomatous skin cancer.
  • For all sexually active patients, the use of adequate barrier contraception (hormonal or barrier method of birth control) will be required during therapy, prior to study entry and for the duration of study participation. Non-pregnant status will be determined in all women of childbearing potential.
  • After being informed of the treatment involved, patients (or their legally authorized representative) must given written consent.

Exclusion Criteria:

  • Patient is currently receiving other investigational agents.
  • Pregnant and nursing women patients are not eligible.
  • Patients known to be HIV positive are ineligible because of the potential inability to modulate immune responses (patient self-report).
  • Patients treated with any bisphosphonate-based therapeutic for any indication, during the previous year.
  • Patients with recent (within 6 weeks) or planned dental or jaw surgery dental or jaw surgery (e.g. extraction, implants).
