摘要

A paired-agent fluorescent molecular imaging strategy is presented as a method to measure drug target engagement inwhole tumor imaging. The protocol involves dynamic imaging of a pair of targeted and control imaging agents prior toand following antibody therapy. Simulations demonstrated that antibody “drug target engagement” can be estimatedwithin a 15%-error over a wide range of tumor physiology (blood flow, vascular permeability, target density) andantibody characteristics (affinity, binding rates). Experimental results demonstrated the first in vivo detection of bindingsite barrier, highlighting the potential for this methodology to provide novel insights in drug distribution/bindingimaging.
