Brief summary

This is an open-label PET/CT study to investigate the safety and clinical monitoring value of 18F-grazy-02 in patients with lymphoma or solid tumors receiving immunotherapy, including immune checkpoint inhibition and CAR-T cell therapy.

Interventions

DRUG18F-grazy-02

18F-grazy-02 PET/CT: after intravenous injection of 2.96-3.7 MBq/kg body weight of quality-controlled 18F-grazy-02 , a Total-body PET/CT uEXPLORER scanner will be applied.

Design outcomes

Primary

MeasureTime frameDescription
Incidence of 18F-grazy-02-emergent Adverse Events1 yearAny adverse events following the administration of the radiotracer will be monitored.
Biodistribution of 18F-grazy-02 in participants1 yearThe distribution of 18F-grazy-02 in tumors and healthy tissues will be examined through PET/CT imaging.

Secondary

MeasureTime frameDescription
Assessing 18F-grazy-02 PET for monitoring immunotherapy responses3 yearsParticipants will be categorized into groups with high or low 18F-grazy-02 uptake in tumor lesions. Therapy efficacy of immunotherapy as assessed by RECIST 1.1 will be compared across these two groups.
