Everolimus, Fluorouracil, Leucovorin, Panitumumab, and Oxaliplatin in Treating Patients With Tumors That Did Not Respond to Treatment

Overview

RATIONALE: Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Drugs used in chemotherapy, such as fluorouracil, leucovorin, and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as panitumumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving everolimus together with combination chemotherapy and/or panitumumab may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of everolimus when given together with fluorouracil, leucovorin, panitumumab, and oxaliplatin in treating patients with solid tumors that did not respond to previous treatment.

OBJECTIVES: Primary * To determine the maximum tolerated dose of everolimus in combination with sequential fluorouracil (5-FU) and leucovorin calcium, panitumumab, modified 5-FU, leucovorin calcium, and oxaliplatin (mFOLFOX6), and mFOLFOX6 with panitumumab in patients with refractory solid tumors. Secondary * To determine the adverse event profile of these regimens. * To correlate response with S6-phosphorylation and AKT-phosphorylation in available archived tumor samples. * To evaluate preliminary evidence of antitumor activity of these regimens using RECIST criteria for a subset of patients with measurable disease. OUTLINE: This is a dose-escalation study. Cohorts of patients are enrolled into treatment groups 1 or 2. If a final cohort of patients is reached in groups 1 and/or 2, additional cohorts of patients are enrolled into treatment group 3. * Group 1: Patients receive oral everolimus once daily on days 1-28. Patients also receive leucovorin calcium IV followed by fluorouracil IV continuously over 46 hours beginning on day 1. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity. * Group 2: Patients receive oral everolimus once daily on days 1-28 and panitumumab IV over 30-90 minutes on day 1. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity. * Group 3: Patients receive oral everolimus once daily on days 1-28, leucovorin calcium IV followed by fluorouracil IV continuously over 46 hours beginning on day 1, and oxaliplatin IV over 2-4 hours on day 1. Some patients may also receive panitumumab IV over 30-90 minutes on day 1. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity. Archived tumor samples are assessed for phospho-AKT, phospho-S6K, and phospho-S6 by immunohistochemistry. After completion of study treatment, patients are followed every 3 months for 1 year.
