Study Summary

This is a first-in-human, pilot study of the novel PET-imaging radiotracer \[89Zr\]DFO-starPEG. The study is designed to obtain preliminary data to support future development of this agent as an imaging surrogate to visualize enhanced permeability and retention (EPR)-mediated tracer uptake before administration of EPR-based nanomedicines.

Primary Outcome

The median and range for intra-tumoral SUVmax within metastatic lesions will be descriptively reported, to assess for intra-tumoral heterogeneity and differences in uptake by site of disease.

Interventions

  • PROCEDURE Specimen Collection
  • DRUG 89-zr-dfo-star polyethylene glycol (StarPEG)
  • PROCEDURE Whole Body Positron Emission Tomography (PET)
