NEW YORK – Immuno-oncology imaging firm ImaginAb has initiated a Phase II trial of its positron emission tomography (PET) imaging agent [89] Zr-Df-IAB22M2C at Dana-Farber Cancer Institute.
The imaging agent uses antibody fragments, so called "minibodies," engineered by ImaginAb to target CD8-positive T cells, and illuminate them with the help of PET imaging. The platform is being developed to provide a whole-body snapshot of immune activity, including that of cancer lesions, which in turn could be used to tailor treatment more precisely to patients.
