monoclonal antibody therapy and/or vaccine therapy in treating patients with locally advanced or metastatic colorectal cancer

Conditions: Colorectal Cancer

Summary: rationale: monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. vaccines made from cancer cells may make the body build an immune response to kill colorectal tumor cells. purpose: phase i/ii trial to study the effectiveness of monoclonal antibody therapy and/or vaccine therapy in treating patients who have locally advanced or metastatic colorectal cancer.

objectives: * determine the safety and tolerability of monoclonal antibody 105ad7 anti-idiotypic vaccine and onycr1, onycr2, and onycr3 allogeneic adenocarcinoma cell-based vaccines in patients with locally advanced or metastatic adenocarcinoma of the colon or rectum. * determine any immunological response to these treatment regimens in these patients. * determine the 6-month and 1-year survival of these patients after receiving these treatment regimens. * determine the tumor response to these treatment regimens in these patients. outline: this is an open-label study. patients are assigned to one of three treatment arms. * arm i: patients receive monoclonal antibody 105ad7 anti-idiotype vaccine (moab 105ad7) plus bcg intradermally (id) weekly for weeks 1 and 2; moab 105ad7 id plus alum adjuvant intramuscularly (im) weekly for weeks 4 and 6; and then moab 105ad7 id alone monthly for up to 12 months. * arm ii: patients receive onycr1, onycr2, and onycr3 allogeneic adenocarcinoma cell-based vaccines plus bcg id weekly for weeks 1 and 2; these vaccines id weekly for weeks 4 and 6, and then monthly for up to 12 months. * arm iii: patients receive moab 105ad7, onycr1, onycr2, and onycr3 allogeneic adenocarcinoma cell-based vaccines, and bcg id weekly for weeks 1 and 2; moab 105ad7 and onycr1, onycr2, and onycr3 allogeneic adenocarcinoma cell-based vaccines id plus alum adjuvant im weekly for weeks 4 and 6; and then moab 105ad7 and onycr1, onycr2, and onycr3 allogeneic adenocarcinoma cell-based vaccines monthly for up to 12 months. patients are followed every 3 months. projected accrual: a total of 45 patients (15 per treatment arm) will be accrued for this study.
