6. Patients who have been exposed to mouse or chimeric antibody within the past 5 years
7. Patients who have been administered some kind of radionuclide earlier than 10 half-lives of the nuclide.
8. Patients with severe, but not fatal disease, for which the principal investigator / investigator has determined that study participation is not appropriate
