研究概览
简要总结
This study evaluates whether tumors present in patients with cancer who are planned to get CAR T-cells have low amounts of oxygen (hypoxia). PET scans may be used to check the amounts of oxygen within areas of cancer with a special radioactive tracer called FAZA that specifically looks for areas of low oxygen. This study is being done to help researchers determine how the amount of oxygen within areas of cancer affect how well CAR T-cells kill cancer cells.
详细描述
PRIMARY OBJECTIVE:
I. To evaluate the incidence of intratumoral hypoxia in patients with relapsed or refractory (R/R) malignancies before treatment with chimeric antigen receptor (CAR) T-cell therapy.
SECONDARY OBJECTIVE:
I. To evaluate the association between intratumoral hypoxia and clinical responses to CAR T-cell therapy.

研究组 & 干预措施
Diagnostic (18F-FAZA PET scan)
Prior to CAR T-cell therapy, patients receive administration of 18F-FAZA IV. Patients will then undergo a vertex-thigh PET scan approximately 2 hours after injection of 18FFAZA lasting 30-45 minutes.
干预措施: Fluorine F 18-fluoroazomycin Arabinoside (Drug)
Diagnostic (18F-FAZA PET scan)
Prior to CAR T-cell therapy, patients receive administration of 18F-FAZA IV. Patients will then undergo a vertex-thigh PET scan approximately 2 hours after injection of 18FFAZA lasting 30-45 minutes.
干预措施: Positron Emission Tomography (Procedure)
