Clinical Trial Summary

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.

Description:

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.

EXPLORATORY OBJECTIVES:

I. To correlate intratumoral hypoxia with markers of CAR T-cell activity and toxicity.

2. To correlate pre-therapy fluorine F 18-fluoroazomycin arabinoside (18F-FAZA) uptake with pre-therapy 18Ffluorodeoxyglucose (FDG) positron emission tomography (PET) uptake (if available).

OUTLINE:

Prior to CAR T-cell therapy, patients receive 18F-FAZA intravenously (IV). Beginning 2 hours after injection, patients undergo a single PET scan. Patients are followed for up to 6 months after CAR T-cell therapy.

Other	Change in Mean Serum Ferritin levels	Will use descriptive statistical methods to present data, including frequencies/percentages for categorical variables and means, medians, standard deviations, and ranges for continuous variables. Will evaluate the effect of intratumoral hypoxia and other exploratory endpoints using chi-squared tests and logistic regressions for categorical variables and two-sample t-tests and linear regressions for continuous variables.	Up to 6 months after CAR T-cell therapy
Other	Change in Mean C-reactive protein (CRP) levels	Will use descriptive statistical methods to present data, including frequencies/percentages for categorical variables and means, medians, standard deviations, and ranges for continuous variables. Will evaluate the effect of intratumoral hypoxia and other exploratory endpoints using chi-squared tests and logistic regressions for categorical variables and two-sample t-tests and linear regressions for continuous variables.	Up to 6 months after CAR T-cell therapy
Other	Change in Mean Fibrinogen Levels	Will use descriptive statistical methods to present data, including frequencies/percentages for categorical variables and means, medians, standard deviations, and ranges for continuous variables.
