Phase I Study of Single Dose Neoadjuvant Zoledronic Acid in Patients With Resectable Pancreas Cancer


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:



A patient will be eligible for inclusion in this study only if ALL of the following
criteria apply;

- 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:

A patient will be ineligible for inclusion into this study if ANY of the following
criteria apply:

- 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).

- Current active dental problems including infection of the teeth or jawbone (maxilla
or mandibular); dental or fixture trauma, or a current or prior diagnosis of
osteonecrosis of the jaw (ONJ), of exposed bone in the mouth, or of slow healing
after dental procedures.

- Patients with a history of aspirin sensitive asthma.
