About this trial

This is a Phase 1b study of participants with Diffuse Large B Cell Lymphoma (DLBCL). The purpose of this study is to identify an optimized lymphodenpletion (LD) regimen by evaluating standard and intermediate doses of Fludarabine (Flu) / Cyclophosphamide (Cy) with or without a fixed dose of total lymphoid irradiation (TLI) in the setting of standard of care CAR T cell therapy.

Radiographically documented measurable disease as per Lugano response criteria (i.e. LDi > 1.5 cm that is FDG avid).

Disqualifiers

Persisting disease bulk (defined as ≥10 cm) on restaging imaging following bridging therapy.

History of malignancy other than nonmelanoma skin cancer or carcinoma in situ (e.g. cervix, bladder, breast) unless disease free for at least 3 years
