Study of Pretargeted Radioimmunotherapy of a Anti-CEA Bispecific Antibody and Lu177-labeled Peptide in Colorectal Cancer

Phase 1
Completed
Conditions
Colorectal Neoplasms
Registration Number
NCT00860860
Lead Sponsor
Radboud University Medical Center
Brief Summary

This study will investigate the toxicity, safety and pharmacokinetics of pretargeted radioimmunotherapy with anti-CEA x anti-hapten bispecific antibody TF2 and Lu-177-labeled di-HSG-DOTA peptide IMP-288. Furthermore, the sensitivity of pretargeted imaging with In-111-labeled IMP-288 as compared to standard methods of tumor detection, and the preliminary efficacy of the therapy.

Detailed Description

Pretherapy cycle with IMP-288 labeled In111.

Exclusion Criteria
  • Known metastases to the brain
  • Chemotherapy, external beam radiation or immunotherapy within 4 weeks prior to study. Limited field external beam radiotherapy to prevent pathological fractures is allowed, when unirradiated, evaluable lesions elsewhere are present.

  • Any unrelated illness, e.g. active infection, inflammation, medical condition or laboratory abnormalities, which in the judgement of the investigator will significantly affect patients' clinical status
  • Life expectancy shorter than 6 months.
