Study Combining Suicide Gene Therapy With Chemoradiotherapy in the Treatment of Non-Metastatic Pancreatic Adenocarcinoma

Recruitment & Eligibility

Inclusion Criteria

Age > = 18 and < = 80.
Non-metastatic, unresectable tumors
No evidence of peritoneal and/or hematogenous metastasis.
Histologically proven (biopsy or cytology) adenocarcinoma.
No evidence of peritoneal and/or hematogenous metastasis.
No prior chemotherapy, radiotherapy or biological therapy.
ECOG performance status 0 - 2.
Subjects must have adequate baseline organ function, as assessed by the following laboratory values, within 30 days before initiating the study therapy:
Adequate renal function with serum creatinine <=1.5 mg/dL or creatinine clearance >=50 mL/min/m2.
Absolute WBC > 4,000/μL.
Hemoglobin > 9.0 g/dL.
Platelet count > 100,000/μL.
Bilirubin < 1.5 mg/dL; SGOT and SGPT < 2.5 times upper limit of normal (ULN).
No history of malignancy within 5 years except for non-melanomatous skin cancer or carcinoma in situ of the cervix.
Men and women with conceptive potential must agree to follow a medically acceptable method of birth control.
Patients on oral warfarin anticoagulation therapy may be included in this study, but must have close monitoring of their coagulation parameters as altered parameters and/or bleeding have been reported in patients taking Xeloda® and such agents concomitantly.
The subject must possess the ability to give informed consent and express a willingness to meet all of the expected requirements of the protocol for the duration of the study.

Exclusion Criteria

Pregnant and lactating women.
Serious non-malignant disease (e.g., congestive heart failure or uncontrolled infections), which, in the opinion of the investigator would compromise study objectives.
Major surgery within four weeks other than diagnostic procedures such as laparoscopy, endoscopic ultrasound and stenting or PEG/PEJ placement.
Islet cell tumor, benign cyst, peri-ampullary carcinoma or any non-adenocarcinomas.
Acute infection. Acute infection is defined by any viral, bacterial, or fungal infection that has required specific therapy within 72 hours of initiation of the study therapy (defined as Day 1).
Active HIV disease.
Previous history of liver disease including hepatitis.
Positive serologic test for Hepatitis B or C at baseline.
Immunosuppressive therapy including systemic corticosteroids. Use of inhaled and topical corticosteroids is permitted.
Serious medical or psychiatric illness or concomitant medication, which, in the judgment of the investigator, might interfere with the subject's ability to respond to or tolerate the treatment or complete the trial.
Impaired immunity or susceptibility to serious viral infections.
Allergy to any product used on the protocol including ciprofloxacin.
Clinical or laboratory evidence of pancreatitis
