Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This partially randomized phase I/II trial studies the side effects and best dose of c-Met inhibitor AMG 337 when given together with oxaliplatin, leucovorin calcium, and fluorouracil and to see how well they work in treating patients with stomach or esophageal cancer that has spread to other places in the body and usually cannot be cured or controlled with treatment. C-Met inhibitor AMG 337 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as, oxaliplatin, leucovorin calcium, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving c-Met inhibitor AMG 337 with oxaliplatin, leucovorin calcium, and fluorouracil may kill more tumor cells.

PRIMARY OBJECTIVES:

I. To evaluate the toxicity of combination therapy with AMG 337 (c-Met inhibitor AMG 337) and mFOLFOX6 (oxaliplatin, leucovorin calcium, and fluorouracil) chemotherapy in patients with advanced or metastatic gastrointestinal (GI) cancers. (Phase I) II. To determine the dose of AMG 337 to be used in combination with mFOLFOX6 chemotherapy in the phase II portion of the trial. (Phase I) III. To determine the pharmacokinetics of AMG 337 in combination with mFOLFOX6. (Phase I) IV. To determine if the addition of AMG 337 to mFOLFOX6 chemotherapy improves median progression-free survival (PFS) in the first line treatment of patients with human epidermal growth factor receptor 2 (Her2Neu) negative and high c-met proto-oncogene (MET) expressing advanced esophagogastric and gastroesophageal junction (GEJ) adenocarcinoma. (Phase II)

SECONDARY OBJECTIVES:

I. To evaluate the addition of AMG 337 to mFOLFOX6 chemotherapy and also to evaluate the placebo/mFOLFOX6 chemotherapy combination in the first line treatment of patients with Her2Neu negative and high c-MET expressing advanced esophagogastric and GEJ adenocarcinoma, with regards to overall survival (OS). (Phase II) II. To evaluate the addition of AMG 337 to mFOLFOX6 chemotherapy and also to evaluate the placebo/mFOLFOX6 chemotherapy combination in the first line treatment of patients with Her2Neu negative and high c-MET expressing advanced esophagogastric and GEJ adenocarcinoma, with regards to response rate and disease control rate. (Phase II) III. To evaluate the addition of AMG 337 to mFOLFOX6 chemotherapy and also to evaluate the placebo/mFOLFOX6 chemotherapy combination in the first line treatment of patients with Her2Neu negative and high c-MET expressing advanced esophagogastric and GEJ adenocarcinoma, with regards to toxicity rates. (Phase II) IV. To evaluate the addition of AMG 337 to mFOLFOX6 chemotherapy and also to evaluate the placebo/mFOLFOX6 chemotherapy combination in the first line treatment of patients with Her2Neu negative and high c-MET expressing advanced esophagogastric and GEJ adenocarcinoma, with regards to time to development of new metastasis. (Phase II) V. To evaluate the addition of AMG 337 to mFOLFOX6 chemotherapy and also to evaluate the placebo/mFOLFOX6 chemotherapy combination in the first line treatment of patients with Her2Neu negative and high c-MET expressing advanced esophagogastric and GEJ adenocarcinoma, with regards to evaluation of MET amplification. (Phase II) VI. To evaluate the addition of AMG 337 to mFOLFOX6 chemotherapy and also to evaluate the placebo/mFOLFOX6 chemotherapy combination in the first line treatment of patients with Her2Neu negative and high c-MET expressing advanced esophagogastric and GEJ adenocarcinoma, with regards to evaluation of MET amplification and MET expression as determined by DAKO immunohistochemistry (IHC) for comparison to Ventana IHC. (Phase II) VII. To evaluate the addition of AMG 337 to mFOLFOX6 chemotherapy and also to evaluate the placebo/mFOLFOX6 chemotherapy combination in the first line treatment of patients with Her2Neu negative and high c-MET expressing advanced esophagogastric and GEJ adenocarcinoma, with regards to a retrospective re-evaluation of the cutpoint used by the computer algorithm for c-MET IHC to assess its ability to distinguish responding versus non-responding patients will be undertaken in this population, so that a potentially more optimal cutpoint to define high c-MET tumors in patients can be identified. (Phase II)

OUTLINE: This is a phase I, dose-escalation study of c-Met inhibitor AMG 337 followed by a phase II study.

PHASE I: Patients receive c-Met inhibitor AMG 337 orally (PO) once daily (QD) on days 1-28; and oxaliplatin intravenously (IV) over 2 hours, leucovorin calcium IV over 2 hours, and fluorouracil IV over 46-48 hours on days 1 and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

PHASE II: Patients are randomized to 1 of 2 treatment arms.

ARM A: Patients receive c-Met inhibitor AMG 337 PO QD on days 1-28; and oxaliplatin IV over 2 hours, leucovorin calcium IV over 2 hours, and fluorouracil IV over 46-48 hours on days 1 and 15.

ARM B: Patients receive placebo PO QD on days 1-28; and oxaliplatin IV over 2 hours, leucovorin calcium IV over 2 hours, and fluorouracil IV over 46-48 hours on days 1 and 15.

In both arms, courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 2 years.
