89zr df-iab2m ...Study Participants
38This is a Phase I/IIa study evaluating the safety and feasibility of [89Zr]Df-IAB2M as an immunoPET tracer for metastatic prostate cancer. Individuals participating in this study will have a FDG PET scan, as well as four (4) PET scans (over a 3 day period) following the injection of [89Zr]Df-IAB2M PET tracer. Three different dosing levels will be explored. The purpose of the study is to demonstrate the safety of [89Zr]Df-IAB2M, ability to detect prostate cancer, and optimal time point and dose level for imaging.
IAB2M is an approximately 80 kDA molecular weight antibody fragment (a "Minibody"). Limited (Phase 0/Proof-of-concept) patient experience with this biologic targeting agent has been previously obtained with SPECT imaging Ex-US, demonstrating targeting of soft tissue and bone lesions in advanced metastatic prostate cancer.
A single intravenous infusion of 5 mCi of [89Zr]Df-IAB2M in a mass dose of 10 mg, 20mg or 50mg.
A single intravenous infusion of 5 mCi of [89Zr]Df-IAB2M in mass doses of either 10 mg, 20 mg or 50 mg (optional).
