Phase 1 Study of BAFF CAR-T Cells (LMY-920) for Treatment of Relapsed or Refractory Chronic Lymphocytic Leukemia / Small Lymphocytic Lymphoma
Paolo Caimi, MD
Summary
CAR-T cell treatment of refractory lymphoma has shown success, particularly with CD-19 targeted CAR-T cells, however, many participants are refractory or relapse after response. Responses are more limited in CLL/SLL, possibly secondary to the suppressive effect of circulating B cells on T cell function. BAFF receptor is a target that has been explored in CLL. Preclinical data indicates that CAR- T cells expressing B-cell activating factor (BAFF) can be another effective strategy to treat refractory CLL. This study aims to explore the efficacy of LMY-920 a BAFF-ligand CAR T cells with depletion of B cells with Obinutuzumab prior to apheresis.
Description
There is a persistent need for development of new, effective therapies for treatment of B cell malignancies. Therapy with CAR-T cells has demonstrated activity against refractory lymphoma, however not all tumors respond or remain in response to CD19 targeted CAR-T cells. While CAR T-cells have activity against CLL/SLL, the rates of response are more limited than non Hodgkin lymphoma. Based on preclinical data of anti BAFF-R CAR T-cells13 as well as preclinical and early phase studies using anti-BAFF-R monoclonal antibodies in CLL) investigators posit that CAR-T cells expressing BAFF (BAFF CAR-…
