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
Trial ID: NCT05737615
Interventional - Phase 1 - Withdrawn
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.
