FOLFOX4 in Patients with Normal and Abnormal Renal Function

This trial is a phase II study of patients with advanced gastrointestinal (GI) malignancies who will be assigned to one of 4 cohorts (normal, mild dysfunction, moderate dysfunction and severe renal dysfunction) based on their baseline measured creatinine clearance then treated with FOLFOX4.

Standard bone marrow and liver function inclusion and exclusion criteria must be met prior to study treatment. FOLFOX4 on the study is given every 2 weeks (1 cycle = 2 weeks) for up to 12 cycles unless there are treatment delays to allow for recovery from toxic effects. Dose modifications are included for protocol specificied toxicities. After 12 treatment cycles on study, patients who are having a beneficial disease response may continue to have oxaliplatin supplied off study to continue the treatment regimen until disease progression, prohibitive toxicity or death.

Oxaliplatin pharmacokinetic studies (serum and urine) are planned during cycles 1 and 2 on each patient. Creatinine clearance will be assessed every 2 cycles and disease status will be assessed every 3 cycles of treatment during the study.

Eligibility & Criteria

Inclusion Criteria:Patients must have histologically or cytologically confirmed locally advanced or metastatic gastrointestinal (GI) malignancy; Patients may have measurable or non-measurable disease; Prior chemotherapy, radiation therapy, hormonal therapy and immunotherapy are allowed, with the exception that patients cannot have had prior treatment with oxaliplatin, cisplatin or other nephrotoxic anticancer agent; Patients must have had no chemotherapy or radiotherapy within 4 weeks (28 days) prior to entering the study; Age 18 or older; Karnofsky performance status of 70% or greater for patients with normal or mildly abnormal renal function and 50% or greater for patients with moderately or severely abnormal renal function; Life expectancy of at least 3 months; Adequate bone marrow function (WBC > or = 3000 cells/mm3, ANC > or = 1500 cells/mm3, platelets > or = 100,000 cells/mm3); Adequate liver function (total bilirubin < or =1.5 times the institutional upper limit of normal (IULN), AST (SGOT)/ALT (SGPT) < or = 2 times the IULN, unless liver metastases are present and documented at baseline by CT or MRI scan (< or = 5 times IULN in that case), alkaline phosphatase < or = 2 times the IULN, unless liver metastases are present and documented at baseline by CT or MRI scan (< or = 5 times IULN in that case)); Patients may have a Grade 1 neurotoxicity at study entry. Absence of deep tendon reflexes as a sole neurological abnormality does not render the patient ineligible; If female, not pregnant or lactating at inclusion. Documentation of a negative serum HCG pregnancy test for women of child bearing potential is required at inclusion; Women of child bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control) prior to study entry, for the duration of study participation and for 6 months after discontinuation of study treatment. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately; Ability to understand and the willingness to sign a written informed consent document. Exclusion Criteria:Patients with active hydronephrosis (patients with a functioning ureteral stent are allowed on study); Patients who have had chemotherapy or radiotherapy within 4 weeks (28 days) prior to entering the study; Patients who have had a major surgery within 4 weeks (28 days) prior to entering the study; Patients who had prior therapy with oxaliplatin, cisplatin or other nephrotoxic anticanger agent; History of allergy to platinum compounds; Patients undergoing therapy with other investigational agents. Patients who received any investigational drug must have discontinued the investigational drug 30 days or more before beginning treatment on this study; Patients with known dihydropyrimidine dehydrogenase (DPD) deficiency; Patients who have had a history of cardiac toxicities while on 5FU/LV therapy or myocardial infarction < or = 6 months prior to study entry; Patients with known brain metastases because of their poor prognosis and because they often develop progressive neurological dysfunction that would confound the evaluation of neurological and other toxicities; Patients with interstitial pneumonia or extensive and symptomatic fibrosis of the lungs; Patients with uncontrolled intercurrent illness (high blood pressure, unstable angina pectoris, symptomatic congestive heart failure (NYHA III or IV), severe cardiac arrhythmia, uncontrolled diabetes or active infection); Pregnant or lactating women.
