PET Imaging Using 64Cu-Tz-SarAr and hu5B1-TCO in People With Pancreatic, Colorectal, Bladder Cancer or Cancers With Elevated CA19.9

A Phase I Study of Pretargeted PET Imaging Using 64Cu-Tz-SarAr and a Trans-Cyclooctene-Modified Humanized 5B1 Immunoconjugate (hu5B1-TCO) in Patients With Pancreatic, Bladder Cancer, Gastrointestinal Malignancies or Solid Tumors With Elevated CA19-9

Summary

The purpose of this study is to find the highest safe dose of hu5B1-TCO and the best dosing schedule of hu5B1-TCO and 64Cu-Tz-SarAr for finding cancer cells that are CA19-9 positive. This study will also help to find out how much radiation the body is exposed to when 64Cu-Tz-SarAr is used, and provide information on the way the body absorbs, distributes, and gets rid of 64Cu-Tz-SarAr.

DIAGNOSTIC_TESTPET ScanParticipants will be imaged up to 4 time points post-injection to allow for biodistribution and dosimetry determination
DRUGhu5B1-TCOOn study day 0, a single slow infusion of hu5B1-TCO will be administered intravenously. Subsequently, either 3 days (n = 3) or 5 days (n = 3) later, a single slow infusion of 64Cu-Tz-SarAr will be administered intravenously.
