Résumé
Date de début de l'étude : 1 avril 1998
Date à laquelle le premier participant a commencé l'étude.OBJECTIVES: Determine the safety and maximum tolerated dose of T cells activated in vitro and modified with chimeric anti-CEA immunoglobulin T cell receptors (Ig TCR) in patients with CEA expressing adenocarcinoma. Determine the pharmacokinetics of this regimen by the persistence of modified T cells in the blood of these patients. Evaluate the immunogenicity of murine sequences in chimeric anti-CEA Ig TCR. Assess immunologic parameters which correlate with the efficacy of this regimen in these patients. Evaluate, in a preliminary manner, the efficacy of this regimen in patients with CEA bearing tumors. OUTLINE: This is a dose escalation study. Peripheral blood lymphocytes (PBL) are harvested. PBL are activated in vitro and then modified with recombinant chimeric anti-CEA immunoglobulin T cell receptors (Ig TCR). Ig TCR modified T cells are reinfused over 30-60 minutes. The estimated maximum tolerated dose (MTD) is defined as the dose at which 2 of 6 patients experience unacceptable toxicity. If the MTD is not reached within the first cohort, a second cohort of 3 patients then receives 4 doses of modified T cells at a higher dose. Patients are followed every 2 weeks for 2 months. PROJECTED ACCRUAL: A total of 6-9 patients will be accrued for this study.
