The proposed study represents the first-ever lymphoma patient imaging studies with 64Cu-GRIP B PET.

To establish the feasibility of granzyme B detection with 64Cu-GRIP B PET in participants with relapsed/refractory NHL receiving CD19-directed CAR-T cell therapy in both cohorts.\n\nSecondary Objectives:\n\n1. To descriptively report the patterns of intra-tumoral uptake of 64Cu-GRIP B on whole body PET, including by site of disease, uptake by tumor type, inter-tumoral and inter-participant heterogeneity, and tumor-to-background signal in participants with participants with NHL.\n2. To descriptively report the number of lesions identified on 64Cu-GRIP B PET compared with conventional imaging in participants with NHL.\n3. To assess the safety of 64Cu-GRIP B in participants with NHL undergoing CAR-T cell therapy.\n\nParticipants will be initially enrolled in Cohort 1.

Disease characteristics, as defined by:\n\n 1. Histologically-confirmed relapsed/refractory non-Hodgkin lymphoma with at least one prior line of therapy.\n 2.

Individuals with treated brain metastases are eligible if follow-up brain imaging after central nervous system (CNS)-directed therapy shows no evidence of progression.\n7. Individuals with new or progressive brain metastases (active brain metastases) or leptomeningeal disease are eligible if the treating physician determines that immediate CNS specific treatment is not required and is unlikely to be required during the first cycle of therapy.\n8. Individuals with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial. The effects of 64Cu-GRIP B on the developing human fetus are unknown. For this reason, participants of childbearing potential must agree to use adequate contraception: all participants should use barrier protection for the duration of study participation and for one month after last administration of study intervention. Should a participant become pregnant or suspect they are pregnant while they or their partner are participating in this study, they should inform their treating physician immediately. Male participants treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and one month after last administration of study treatment.\n\nExclusion Criteria:\n\n1. Any condition that, in the opinion of the Principal Investigator, would impair the participant's ability to comply with study procedures.\n2. Pregnant participants are excluded from this study because the effects of 64Cu-GRIP B on the developing human fetus are unknown. There is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the nursing parent with 64Cu-GRIP B, breastfeeding should be discontinued if the nursing parent receives 64Cu-GRIP B.\n3.
