About CD8 ImmunoPET

The Zr 89 CD8 ImmunoPET agent (zirconium Zr 89 crefmirlimab berdoxam) is a Zr 89 -labelled Minibody that binds the CD8 receptor on human T cells and is used for quantitative, non-invasive PET imaging of CD8 T cells in patients. CD8 T cells are the main effector cells involved in the immune response against tumor cells induced by immunotherapies and they also play a key role in multiple autoimmune diseases. As such, quantitative imaging of CD8 T cells can be used to diagnose the immune status of a patient, to measure the efficacy of immunotherapies and predict patient outcomes.
