Brief Summary

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

In this study, a new chemotherapeutic agent, panitumumab, will be tested in combination with another chemotherapeutic drug, capecitabine, along with external radiotherapy, to find out whether this combination is effective and safe to use before surgery.

Detailed Description

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

Surgical resection remains the standard procedure for patients with localized resectable pancreatic cancer.

Neoadjuvant or preoperative therapy with chemotherapy and radiation therapy has been proposed as an alternative approach in patients with localized pancreatic adenocarcinoma.

Advantages are: 1) early start of systemic therapy targeting micrometastatic disease; 2) increased compliance with chemoradiotherapy; 3) increase primary tumor complete resection rates; 4) avoidance of surgery in patients with rapidly developing metastatic disease; and 5) importantly, it provides an important resource for research in terms of tissue acquisition before and after therapy . Finally, this is an opportunity to test the safety and efficacy of a novel combination of weekly panitumumab, oral capecitabine and radiation in pancreatic cancer.

Interventions

Neoadjuvant capecitabine, panitumumab and radiation

Patients will receive six weekly doses of panitumumab (2.5mg/kg) in conjunction oral capecitabine 825 mg/m2 PO bid Mon-Friday and external beam radiation therapy. Panitumumab and oral capecitabine will begin on the first week of external beam radiotherapy and will continue throughout the course of external beam radiation therapy, and will be discontinued following the conclusion of external beam radiation therapy.

Patients will be reevaluated for surgical resection 4-6 weeks after completion of neoadjuvant therapy.

After surgical resection, adjuvant systemic chemotherapy with gemcitabine for six months is strongly recommended for all patients.

Eligibility Criteria

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

Inclusion Criteria

1. Cytological or histological confirmation of pancreatic adenocarcinoma is required.
2. Only patients with localized and apparently resectable, non-metastatic tumors are eligible. All patients must be staged with a chest X-ray or chest CT and abdominal and pelvic CT scan or MRI.

One of the following radiological criteria must be met and recorded in chart by dedicated surgeon prior to enrollment.

A)Localized, potentially resectable : 1) no evidence of tumor extension to the celiac axis, hepatic artery or superior mesenteric artery; 2) no evidence of tumor encasement or occlusion of superior mesenteric vein (SMV) or the SMV/portal vein(PV) confluence; 3) no evidence of visceral or peritoneal metastasis

B)Borderline resectable: 1) no extra pancreatic disease, (2) the following possible tumor-vessel relationships: an SMV-PV confluence that can be reconstructed even if short segment venous occlusion is present; tumor abutment of the SMA of ≤180°; or short segment encasement of the hepatic artery amenable to resection and reconstruction.

Patients with the following radiological criteria are NOT eligible:

A) Locally advanced disease: (1) no extra pancreatic disease, (2) tumor encasement of the SMA or celiac axis defined as tumor involvement of \>180° of the arterial circumference. B) Radiographic evidence of distant organ or peritoneal metastases.
3. Age \> 18 years.
4. ECOG performance status 0 and 1.
5. Patient must have adequate hematological, renal and hepatic function defined as:

WBC \> 2,000 cells/mm3 ANC\>1500 cells/mm3 Hemoglobin \> 9.0 g/dL Platelets \> 100,000 cells/mm3 Serum creatinine \< 1.5 x upper limit of normal (UNL) or a calculated creatinine clearance of \> 50 mL/min calculated by Cockcroft-Gault method Total bilirubin \< 2.5 mg/dl AST \< 3x upper limits of normal ALT \< 3x upper limits of normal
6. Serum calcium and magnesium levels within limits of normal
7. Patients may not have any prior therapy for carcinoma of the pancreas, nor prior abdominal radiation therapy.

Exclusion Criteria

1. Patients with any other malignancy within 5 years of study entry, except curatively treated basal cell carcinoma or squamous cell carcinoma of the skin or carcinoma in situ of the cervix.
2. Psychiatric illness which would prevent the patient from giving informed consent.
3. Serious medical illness which would limit anticipated survival to \< 12 weeks.
4. Protocol treatment would pose significant risk to an unborn child. Pregnant women should not be enrolled, and women of child-bearing age should be strongly encouraged to practice effective birth control during and for six months after the trial. Non-pregnant and non-breast-feeding. Female participants of child-bearing potential must have a negative urine or serum pregnancy test prior to registration. Perimenopausal participants must be amenorrheic \> 12 months to be considered not of childbearing potential. All patients (men and women) of reproductive potential must agree to use an effective method of birth-control while receiving study therapy and for six months after completion of therapy.
5. Inability to swallow medication. Patients should have adequate, unassisted oral intake.
6. Inability to hold still and cooperate during radiotherapy.
7. Prior history of interstitial lung disease e.g. pneumonitis or pulmonary fibrosis or any evidence of interstitial lung disease on baseline chest CT scan.
