Brief Summary:
This 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.

Condition or disease Intervention/treatment Phase
Metastatic Prostate Cancer Biological: [89Zr]Df-IAB2M Phase 1 Phase 2

Detailed Description:
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.

Outcome Measures
Go to

Primary Outcome Measures :
  1. Determine the safety of [89Zr]Df-IAB2M PET in patients with metastatic prostate cancer. [ Time Frame: Day 1 (Infusion Day) through Day 7 ]
    To assess the safety of a single dose of of [89Zr]Df-IAB2M


Secondary Outcome Measures :
  1. [89Zr]Dr-IAB2M PET/CT quantitative assessment of metastatic prostate cancer [ Time Frame: Day 1 (Infusion Day) to Day 3 ]
    To determine the ability of 89Zr-Df-IAb2M PET to detect known sites of disease in patients with metastatic prostate cancer

  2. Optimal parameters for imaging with [89Zr]Df-IAB2M [ Time Frame: Day 1 (Infusion Day) to Day 3 ]
    To evaluate the mass dose and hours post infusion that provides optimal detection of metastatic prostate cancer

  3. Sensitivity of [89Zr]Df-IAB2M to detect metastatic prostate cancer [ Time Frame: Up to 4 weeks ]
    To compare the results of the biopsy and FDG PET scan to the [89Zr]Df-IAB2M images


Other Outcome Measures:
  1. Determine the radiation dose levels from a single infusion of [89Zr]Df-IAB2M in individuals with metastatic prostate cancer [ Time Frame: Day 1 (Infusion Visit) to Day 3 ]
    Evaluate the biodistribution of [89Zr]Df-IAB2M with PET/CT scans, whole body counts and blood samples to determine the radiation dose to organs in individuals with metastatic prostate cancer.
