MedicalResearch.com: What is the background for this study?
Response: While CD19-targeted CAR T cell therapy has garnered clinical success and FDA approval for the treatment of large B cell lymphoma, approximately half of patients suffer from primary resistance or relapse. Increasing evidence suggests that resistance mechanisms are supported by the tumor microenvironment (TME). Cytokines secreted by CAR T cells can remodel the TME, determining the phenotype and function of other immune cells.

MedicalResearch.com: What is the background for this study?
Response: New data from our investigator-sponsored Phase 1 study exploring duvelisib in combination with venetoclax will be presented at ASH on December 7. In relapsed or refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), duvelisib plus venetoclax demonstrated promising clinical activity, a manageable tolerability profile, and identified a recommended Phase 2 dosing (RP2D) regimen.
