Summary
This is an open-label pilot study of a new PET/CT imaging agent MNPR-101-DFO\*-89Zr in patients with solid tumor cancers. These cancers may include bladder/urothelial, triple-negative breast, lung, colorectal, gastric, ovarian, and pancreatic cancers.
MNPR-101-DFO\*-89Zr is made of MNPR-101, a humanized IgG1 monoclonal antibody and a radioisotope Zirconium-89. This imaging agent may show where tumors are present in the body using a PET-scan.
Participants will be injected with the radioactive tracer once. After injection, participants will have 3 PET-scans. Each PET-scan will take about 30 minutes. The PET-scans are on separate days within 10 days after injection (e.g., 2 hours after injection, plus 3-5 days and 7-10 days after injection). Furthermore, the investigators will take blood samples 6 times (5 mL each). Blood pharmacokinetics (PK) will be measured on Day 1 at 10 min, 1h, 2h, once on Days 3-5, and once on Days 7-10.
The study will see if the new imaging agent correctly shows all tumors. In the future, this method may be useful to help predict who will benefit from certain therapies.
