STUDY SYNOPSIS Objectives: Primary: 1. Determine the response rates and overall survival in patients with metastatic renal cell carcinoma (RCC) receiving pre-treatment with Leukine-dexamethasone vs Leukine alone in combination with gemcitabine-5-FU. 2. Determine if pre-treatment with the combination of Leukine-dexamethasone is more effective than pre-treatment with Leukine alone in reducing the hematopoietic and non-hematopoietic toxicities of gemcitabine-5-FU in patients with metastatic RCC. Secondary: 1. Determine the effects of the combination of Leukine-dexamethasone vs Leukine alone on the number and function of peripheral blood dendritic cells, and cytokine levels when given prior to gemcitabine-5-FU in patients with metastatic RCC. 2. Determine quality of life and toxicity of treatment in patients with metastatic RCC receiving pre-treatment with Leukine-dexamethasone vs Leukine alone in combination with gemcitabine-5-FU. 3. Determine the dose intensity administered in both treatment groups. Study Design: – Overall study design: A randomized Phase II study in patients with metastatic RCC Patients will receive chemotherapy with gemcitabine-5-FU. Patients will receive prior to each chemotherapy the combination of Leukine alone (Cohort 1) or Leukine-dexamethasone (Cohort 2). – Patient eligibility: a) chemotherapy naive patients with biopsy proven RCC, b) PS (ECOG), 0, 1, or 2, c) measurable disease by RECIST criteria, d) previous immunotherapy and anti-angiogenic therapy is allowed, e) adequate bone marrow, renal and hepatic function as defined by AGC > 1500 and PLC > 100,000 mm3 and serum creatinine and bilirubin < 1.5 mg/dl. – Chemotherapy: Cohorts 1 and 2: Days 7 and 21: gemcitabine 1.0 g/m2 intravenously over 30 minutes; Days 7-8 and 21-22: Folinic acid 200 mg/ m2, then 5-FU 400 mg/ m2, intravenously over 30 minutes followed by 5-FU 600 mg/ m2 intravenously over 24 hours. – Study Drugs: – Cohort 1, Leukine, 250 ug/m2 daily (8 am) subcutaneously days 1, 2, 3, 4, 5, and 15, 16, 17, 18, and 19; – Cohort 2, Leukine, 250 ug/m2 daily (8 am) subcutaneously days 1, 2, 3, 4,5, and 15, 16, 17, 18, and 19 and dexamethasone 12 mg every 12 hours (8 am and 8 pm) orally days 3, 4, 5,6, 7, 17, 18, 19, 20, and 21. – Evaluations during this trial: Baseline: history and physical examination with vital signs/weight, estimation of performance status (PS), CAT scans of chest, abdomen and pelvis, EKG, CBC/differential, urinalysis, complete biochemistry profile (CMP) (12 component) and quality of life assessment. Prior to each course: interim history, physical examination with vital signs/weight, grading of all toxicities, and estimation of PS, CMP, and CBC/differential. Prior to course 3, 5, and thereafter (every other course): CAT scans of chest, abdomen, and pelvis, tumor response and quality of life assessment. Each week after initiation of study (ie day1, course 1): CBC/differential, x 3 (Monday Wednesday and Friday). Biologic studies to include assessment of dendritic cell number and function (20 ml blood), days 1 and 7 of course 1.

Patients must have adequate organ and marrow function as defined as follows: leukocytes >3,000/mm3, absolute neutrophil count >1,500/mm3, hemoglobin >8.0g/dl, platelets >100,000/mm3, total bilirubin and serum creatinine must be < 1.5 mg/dl. Liver transaminases (SGOT and/or SGPT) may be up to 2.5 institutional upper limit of normal (ULN) if alkaline phosphatase is <ULN or alkaline phosphatase may be up to 4 ULN if transaminases are <ULN. 9. Patients must have the ability to understand and the willingness to sign a written informed consent document. Patients have the right to withdraw from the study at any time, without prejudice. Exclusion Criteria:
1.

Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, uncontrolled or untreated cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. 3. Patients requiring any non study corticosteroids for any reason are excluded. 4. Pregnant women are excluded from this study because of the teratogenic potential of 5-FU and gemcitabine. Women of child-bearing 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 or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. Lactating women are also excluded.
