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.

About Lutetium-177

Lutetium-177 n.c.a is a radioisotope of choice for targeted radionuclide therapy. Lu-177 n.c.a production process enables treatment options that have the potential to improve treatment outcomes for certain cancer patients today and more potential treatment options in future under clinical development. The unique properties of Lu-177 n.c.a make it a theranostically desirable radioisotope for peptide receptor radionuclide therapy (PRRT) to treat certain cancers like Neuro Endocrine Tumors (NET) and Prostate cancer. Lutetium-177 is registered at the FDA.
