Clinical trial: Neoadjuvant CAPOXIRI Chemotherapy in the Treatment of Pancreatic Adenocarcinoma Protocol

Summary: The combination of capecitabine, oxaliplatin, and irinotecan (CAPOXIRI) may be better than other combinations used to treat earlier stage pancreatic cancer patients with resectable (able to be cut out), borderline resectable, and locally advanced pancreatic adenocarcinoma. For subjects who can not obtain Capecitabine can be treated with 5-Fluorouracil (5-FU) along with Oxaliplatin and Irinotecan. Though all of the drugs in this study have been approved by the FDA, their combination is investigational. The purpose of this study is to evaluate the effects of CAPOXIRI (good and bad) on you and your cancer.

Detailed description: Introduction:
  This is a phase II study evaluating the treatment adherence rate, efficacy and safety of neoadjuvant chemotherapy with capecitabine, oxaliplatin and irinotecan (CAPOXIRI) in patients with resectable (able to be cut out), borderline resectable and locally advanced pancreatic adenocarcinoma. Neoadjuvant CAPOXIRI chemotherapy is an innovative strategy that builds on the advancement associated with oxaliplatin, irinotecan, fluorouracil, and folinate (FOLFIRINOX regimen) chemotherapy in patients with metastatic disease. Building on the FOLFIRINOX regimen the use of CAPOXIRI is among the most clinically relevant projects for patients diagnosed with earlier stage pancreatic adenocarcinoma with the goal of improving patient outcomes and advancing our knowledge and understanding of this devastating disease.
  The primary end point is the treatment adherence rate (TAR) which is the percentage of patients who complete 75% of the planned treatment (dose) for their diagnostic strata (resectable disease and borderline resectable/locally advanced disease).
  Secondary end points are: Overall survival (OS), Disease-free survival (DFS; for those patients who are rendered disease-free by surgical resection), Progression Free Survival (PFS), Response Rate (RR), toxicity, and R0 resection rate (for patients stratified as having resectable disease and borderline resectable disease).
  Background and Study Rationale:
  It is estimated that 36,800 people will die of pancreatic cancer in the United States in 2010. Surgical resection offers the only chance of cure, but only 15-20% of cases are potentially resectable at present. Furthermore, prognosis is poor, even for those undergoing complete resection. Reported five-year survival rates following pancreatic-duodenectomy (surgery of the small intestine and pancreas) for node-negative disease is 25-30% and for node-positive disease is 10%.
  The purpose of this study is to evaluate the effects of the combination of capecitabine, oxaliplatin, and irinotecan (CAPOXIRI) on the disease. This research is being done because we think that this combination, CAPOXIRI, may be better than other combinations used to treat your stage of pancreatic cancer.
  A research study like this one has been done which shows that a similar combination of drugs including oxaliplatin, irinotecan and 5-fluorouracil (which is in the same class as capecitabine) can be effective in treating patients with pancreatic cancer who have more advanced disease than you. All of the drugs that are being used in this study have been approved by the FDA (Food and Drug Administration).

  5. An interval between initial diagnosis and consent of ≤ 42 days.
  6. An interval between consent and initiating protocol-directed therapy of ≤ 14 days.
  7. CT scan to stratify as resectable versus borderline resectable/locally advanced status within 28 days of initiating protocol-directed therapy.
  8. A general level of health that would indicate a life expectancy of 5 years, excluding the patient's cancer diagnosis.
  9. No prior chemotherapy, immunotherapy or radiotherapy for pancreatic adenocarcinoma.

  15. Patients must not have other serious illness or medical conditions including, but not limited to the following: New York Heart Association (NYHA) Class II or greater congestive heart failure or unstable angina pectoris, uncontrolled hypertension or arrhythmias, active bacterial infections, or unstable diabetes mellitus.
  16. Patients must be disease-free of prior invasive malignancies for ≥ 5 years with the exception of curatively-treated basal cell or squamous cell carcinoma of the skin.
  Exclusion Criteria:
  1. Patients less than 18 years of age.
  2. CT evidence of metastatic disease.
  3. Pregnancy or considering pregnancy at the time of study entry.
  4. Breast feeding at the time of study entry.
  5. Prior therapy for pancreatic cancer including irradiation, chemotherapy, or immunotherapy.
  6. Receiving concurrent chemotherapy, immunotherapy, or radiotherapy that is not part of this protocol while participating in this study.
  7. Receiving concurrent treatment with any other investigational drug while on this protocol.
  8. Prior malignancy within 5 years, excluding squamous or basal cell carcinoma of the skin that has been effectively treated, carcinoma in situ of the cervix, lobular carcinoma in situ of the breast, or ductal carcinoma in situ of the breast.
  9. Non-malignant disease that would preclude protocol participation or follow-up.
