The company said 89Zr-Df-IAB22M2C is a first in class imaging agent that visualizes the immune system using non-invasive, whole-body in vivo PET imaging of CD8 T cells. Using its 'Minibody' platform, the technology targets and visualizes CD8+ T-cells to provide highly-specific, quantitative assessment of the immunological status of each cancer lesion within a patient, potentially enabling treatment to be tailored quickly and specifically to the needs of that patient.
