Brief Summary
This phase Ib trial studies the effects of NKTR-255 in combination with chimeric antigen (CAR)-T cell therapy and to see how well they work in treating patients with large B-cell lymphoma that has com...
Detailed Description
OUTLINE: Patients receive standard of care lymphodepletion therapy consisting of cyclophosphamide and fludarabine on days -5 to -3 followed by liso-cel CAR-T cell infusion on day 0. Patients then rec...

Exclusion
