FDG-PET/CT Imaging as Early Predictor of DP

July 10, 2023 updated by: Abramson Cancer Center at Penn Medicine

A Pilot Study Using FDG-PET/CT Imaging as an Early Predictor of Disease Response in Lymphoma Subjects Receiving Redirected Autologous CART- 19 T-cell Immunotherapy

In this study the investigators would like to describe FDG-PET/CT responses in patients who are receiving CART-19 immunotherapy for Follicular Lymphoma (FL), Diffuse Large B-cell Lymphoma (DLBCL), and Mantle Cell Lymphoma (MCL) as part of UPCC #13413. Subjects will undergo two FDG-PET/CTs. One performed within 6 weeks of CART-19 infusion and a repeat scan at about 1 month after infusion.

Non-Probability Sample

Study Population

Subjects with DLBCL and FL treated on a phase I study with Autologous T cells

Description

Inclusion Criteria:

  • Subjects enrolled on the study UPCC 13413 Pilot Study Of Redirected Autologous T Cells Engineered To Contain Anti-Cd19 Attached To Tcr And 4-1bb Signaling Domains In Patients With Chemotherapy Resistant Or Refractory Cd19+ Lymphoma CART-19 autologous T-cell trial with relapsed or refractory DLBCL and FL. As this is a pilot study, we plan to enroll 4 subjects from the two disease types of interest.
  • Subjects ≥ 18 years of age
  • Subjects able to provide informed consent and agree to comply with study procedures

Exclusion Criteria:

  • Subjects who are pregnant or lactating.
  • Subjects will be co-enrolled in this study and UPCC 13413 and therefore must comply with the UPCC 13413 Pilot Study Of Redirected Autologous T Cells Engineered To Contain Anti-Cd19 Attached To Tcr And 4-1bb Signaling Domains In Patients With Chemotherapy Resistant Or Refractory Cd19+ Lymphoma requirements pertaining to pregnancy, lactation, conception and contraception use throughout their participation in both studies.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Diffuse Large B-cell Lymphoma
There is no intervention. Will undergo baseline FDG-PET/CT to be performed within 6 weeks of infusion of CART-19 autologous T-cell therapy in a different study and then undergo repeat FDG-PET/CT at approximately 1 month after infusion. Infusion of CART-19 autologous T-cell therapy is not part of this study.
Other: There is no intervention
Subjects undergo FDG-PET CT scans in order to determine lesional FDG intake and changes in lesional FDG uptake.
Follicular Lymphoma
There is no intervention. Will undergo baseline FDG-PET/CT to be performed within 6 weeks of infusion of CART-19 autologous T-cell therapy in a different study and then undergo repeat FDG-PET/CT at approximately 1 month after infusion. Infusion of CART-19 autologous T-cell therapy is not part of this study.
Other: There is no intervention
Subjects undergo FDG-PET CT scans in order to determine lesional FDG intake and changes in lesional FDG uptake.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Global objective tumor response measured from serial PET/CT scans
Time Frame: 1 month
global objective tumor response measured from serial PET/CT scans as the change (absolute and relative (%)) in total metabolically active tumor volume (i.e., the total volume (in cc) of FDG-avid tumor throughout the body) between pre-treatment and post-treatment PET/CT scans.
1 month
