Brief summary

RATIONALE: Radiolabeled monoclonal antibodies, such as yttrium Y 90 DOTA anti-CEA monoclonal antibody M5A, can find tumor cells and carry tumor-killing substances to them without harming normal cells. This may be an effective treatment for advanced cancer. PURPOSE: This phase I trial is studying the side effects and best dose of yttrium Y 90 DOTA anti-CEA monoclonal antibody M5A in treating patients with advanced solid tumors.

Detailed description

OBJECTIVES: * To establish the maximum tolerated dose of yttrium Y 90 DOTA anti-CEA monoclonal antibody M5A and describe the toxicities at each dose studied. * To estimate radiation doses to whole body, normal organs, and tumor through serial nuclear imaging studies after intravenous infusion of the yttrium Y 90 DOTA anti-CEA monoclonal antibody M5A. OUTLINE: This is a dose-escalation study of yttrium Y 90 DOTA anti-CEA monoclonal antibody M5A (MOAB M5A). * Biodistribution: Patients receive indium In 111 radiolabeled anti-CEA MOAB M5A IV over 30 minutes. Patients undergo serial nuclear scans, single photon emission computed tomography (SPECT), and blood and urine sampling over 1 week to estimate absorbed radiation doses to tumor, normal organs (i.e., liver, lung, kidney, and bone marrow), and whole body. * Treatment: No more than 2 weeks later, patients with adequate biodistribution receive yttrium Y 90 DOTA anti-CEA MOAB M5A IV over 30 minutes on day 1. Patients then undergo serial nuclear scans, SPECT, and blood and urine sampling over 1 week to estimate absorbed radiation doses to tumor, normal organs (i.e., liver, lung, kidney, and bone marrow), and whole body. Treatment repeats every 6-10 weeks for up to 2 courses in the absence of disease progression or unacceptable toxicity. Blood and urine samples are collected periodically for analysis of total activity by radiometric high performance liquid chromatography and to acquire data on antibody metabolism and pharmacokinetics. After completion of study treatment, patients are followed every 3 months for up to 6 months.
