About
This randomized phase I/II trial is studying the side effects and best dose of monoclonal antibody therapy when given together with gemcitabine hydrochloride and erlotinib hydrochloride and to see how well they work compared with giving gemcitabine hydrochloride and erlotinib hydrochloride alone as first-line therapy in treating patients with metastatic pancreatic cancer that cannot be removed by surgery. Drugs used in chemotherapy, such as gemcitabine hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies 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 erlotinib hydrochloride and gemcitabine hydrochloride together with monoclonal antibody therapy may kill more tumor cells.
Full description
PRIMARY OBJECTIVES:
I. To assess the appropriate dose of IMC-A12 (cixutumumab) to use in combination with gemcitabine (gemcitabine hydrochloride) and erlotinib (erlotinib hydrochloride). (Phase I) II. To assess progression-free survival in patients with metastatic pancreatic cancer treated with IMC-A12 plus gemcitabine and erlotinib compared to those treated with gemcitabine plus erlotinib alone. (Phase II) III. To assess overall survival in each of the two treatment arms in this group of patients. (Phase II) IV. To assess the total response probability (confirmed and unconfirmed, complete and partial responses) in each of the two treatment arms in the subset of this group of patients with measurable disease. (Phase II) V. To assess the qualitative and quantitative toxicities in each of the two treatment arms in this group of patients. (Phase II)
OUTLINE: This is a multicenter, phase I, dose-escalation study of cixutumumab followed by a randomized, phase II study.
Patients are initially enrolled into the phase I portion of the study to determine the recommended phase II dose (RPTD) of cixutumumab. Once the RPTD is determined, patients are enrolled into the phase II portion of the study.
PHASE I (LIMITED INSTITUTIONS): Patients receive erlotinib hydrochloride orally (PO) once daily on days 1-28, gemcitabine hydrochloride intravenously (IV) over 30 minutes on days 1, 8, and 15, and cixutumumab IV over 60 minutes on days 1, 8, 15, and 22. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.
PHASE II (ALL SWOG MEMBERS): Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive erlotinib hydrochloride, gemcitabine hydrochloride, and cixutumumab at the RPTD as in phase I.
ARM II: Patients receive erlotinib hydrochloride and gemcitabine hydrochloride as in arm I.
In both arms, treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.
Previously collected tumor tissue is obtained for gene expression analyses by RT-PCR, RNA isolation, and cDNA synthesis. Blood samples are collected periodically for correlative studies. Samples are assessed for the potential relationship between gene expression levels, germline polymorphisms, Ras and P13K mutations and progression-free survival and overall survival.
After completion of study treatment, patients are followed every 6 months for up to 3 years.
