General Information



Disease Group:	Gastrointestinal	Supported By:	N/A

Phase of Study:	Phase II	Return Visit:	Once every 3 weeks.

Treatment Agents:	Capecitabine Oxaliplatin	Home Care:	Capecitabine will be administered orally as twice-daily intermittent therapy on days 1-14, followed by 7 days without treatment.

Treatment Loc:	Only at MDACC

Estimated Length of Stay in Houston:	Hospitalization is not required.


Description/ Intervention:	The goal of this clinical research study is to find out how effective oxaliplatin and capecitabine are when used together in the treatment of advanced cancer of the small bowel. The safety of this combination treatment will also be studied.

Study Objectives / Outcomes

1.1 The primary objective is to determine the objective response rate (complete plus partial) to the combination of capecitabine (Xeloda) and oxaliplatin (Eloxatin) (XELOX) in patients with adenocarcinoma of the small bowel and ampulla of Vater.

1.2 The secondary objectives include determining the toxicity, time-to-treatment failure, and overall survival rates in patients treated with this combination.

Enrollment Eligibility

If you do not meet the enrollment eligibility, there may be other treatment options for you. Please Contact the Referral Office for more information.

Inclusion Criteria:

1) Patients must have histologically or cytologically confirmed adenocarcinoma of the small bowel or ampulla of Vater that is either unresectable or metastatic.

2) Patients must have measurable disease as per the modified RECIST criteria.

3) Patients may be previously untreated or have received previous systemic therapy, limited to 5-FU/leucovorin or capecitabine, as adjuvant or neoadjuvant therapy or as a radiosensitizer. Patients may have received capecitabine or 5-FU administered as a radiosensitizing agent concurrently with external beam radiotherapy as preoperative or postoperative therapy. Patients may have received capecitabine or 5-FU/leucovorin as part of adjuvant chemotherapy.

4) If radiation was previously received, the measurable disease must be outside the previous radiation field.

5) A minimum of 4 weeks must have elapsed since completion of any prior chemotherapy or radiotherapy. A minimum of 4 weeks must have elapsed since any prior surgery.

6) ECOG Performance Status of less than or equal to 2.

7) Adequate bone marrow function defined as absolute peripheral granulocyte count of greater than or equal to 1500 mm3, platelet count greater than or equal to 1500 mm3, and hemoglobin greater than or equal to 10 gm/dL.

8) Adequate renal function, defined as serum creatinine less than or equal to 1.5 X ULN and calculated creatinine clearance >30 mL/min.

9) Patients must have adequate hepatic function: total bilirubin less than or equal to 1.5 gm/dL; serum albumin greater than or equal to 2.5 gm/dL. If the patient does not have liver metastasis, transaminases may be up to 2 X the ULN. If the patient has liver metastasis, transaminases up to 5 X ULN are allowed.

10) Negative urine or serum pregnancy test in women with childbearing potential, within one week prior to initiation of treatment.

11) The effects of the combination of oxaliplatin and capecitabine on the developing fetus are unknown. For this reason, women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control) prior to study entry and for the duration of study participation. Should a woman become pregnant while participating in this study, she should inform her treating physician immediately.

12) Patients must sign an Informed Consent and Authorization indicating that they are aware of the investigational nature of this study and the known risks involved.

13) Age greater than or equal to 18 years. Because no dosing or adverse event data are currently available on the use of XELOX in patients <18 years of age, children are excluded from this study.

14) Patients taking therapeutic doses of coumarin-derivative anticoagulants should be switched to LMWH. Low-dose Coumadin (e.g. 1 mg PO per day) in patients with in-dwelling venous access devices is allowed.

Exclusion Criteria:

1) Patients with prior exposure to platinum therapy are excluded. Patients who have received prior chemotherapy for metastatic disease are excluded.

2) Patients who have had chemotherapy within 4 weeks (6 weeks for nitrosoureas or Mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier.

3) Patients may not be receiving any other investigational agents nor have received any investigational drug 30 days prior to enrollment.

4) Patients with known brain metastases are excluded from this clinical trial because of their poor prognosis and their risk for progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.

5) Gastrointestinal tract disease resulting in an inability to take oral medication or a requirement for IV alimentation. Prior surgical therapy affecting absorption.

6) Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

7) Because patients with immune deficiency are at increased risk of lethal infections when treated with marrow-suppressive therapy, HIV-positive patients receiving combination anti-retroviral therapy are excluded from the study because of possible pharmacokinetic interactions with XELOX. Appropriate studies will be undertaken in patients receiving combination anti-retroviral therapy when indicated.

8) Patients with extensive symptomatic fibrosis of the lungs.

9) Peripheral neuropathy > grade 1.

10) Known DPD deficiency

11) Patients receiving therapeutic doses of coumarin-derivative anticoagulant therapy are excluded since a drug interaction between capecitabine and coumarin anticoagulants has been reported. Patients requiring anticoagulation who may be safely switched to LMWH are eligible.
