RATIONALE: Diagnostic procedures, such as radionuclide imaging using bispecific antibody, may help find colorectal cancer cells and learn the extent of disease.

PURPOSE: This phase I trial is studying how well a bispecific antibody works in finding tumor cells in patients with colorectal cancer.

Condition Intervention Phase

Study Type: Interventional
Study Design: Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Phase I Study of Preoperative Detection of Colorectal Carcinoma With Bispecific Antibody Pretargeting

Primary Outcome Measures:
  • Pharmacokinetics
  • Tissue distribution

Estimated Enrollment: 9
Study Start Date: November 2008
Estimated Primary Completion Date: March 2010 (Final data collection date for primary outcome measure)
Detailed Description:


  • Assess the pharmacokinetics and tissue distribution of anti-CEA x anti-HSG bispecific monoclonal antibody TF2 in patients with colorectal cancer.

OUTLINE: This is a multicenter study.

Patients receive iodine I 131-labeled anti-CEA x anti-HSG bispecific monoclonal antibody TF2 (^131I-TF2) IV over 10-20 minutes on day 1. Patients also undergo whole-body external scintigraphy at various times during the study.

Blood samples are collected at baseline and periodically after ^131I-TF2 infusion for pharmacokinetic studies and ^131I-TF2 biodistribution by ELISA and radioactivity measurements.
