Official title
A Phase I/Ib PET Imaging Study of 64Cu-GRIP B, a Radiotracer Targeting Granzyme B, in Patients Receiving CD19-directed CAR-T Therapy
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a phase I/Ib imaging study of granzyme B, 64-copper granzyme targeting restricted interaction peptide specific to family member B (64Cu-GRIP B) Positron Emission Tomography (PET) in patients with relapsed/refractory non-Hodgkin's lymphoma (NHL) receiving CD19-directed Chimeric antigen receptor T cells (CAR-T) therapy. The proposed study represents the first-ever lymphoma patient imaging studies with 64Cu-GRIP B PET. The tracer is designed to detect extracellular granzyme B as it is secreted by activated immune cells in the tumor microenvironment, which may highlight tumors that will exhibit a durable response to Cluster of Differentiation 19 (CD19)-directed CAR T-cell therapy.
