Fateeha Furqan, MD, Medical College of Wisconsin, Milwaukee, WI, presents the results of a Phase I/II trial (NCT04186520) of pirtobrutinib, a non-covalent BTK inhibitor, combined with LV20.19, a lentiviral transduced bispecific anti-CD20/CD19 CAR T-cell, to improve outcomes in patients with relapsed/refractory (R/R) lymphomas. Whilst immunophenotyping was similar between groups that received LV20.19 monotherapy and in combination with pirtobrutinib, the pirtobrutinib group had a stronger, although not statistically significant, polyfunctional strength index. The overall response rate (ORR) in that group was 82%, with some grade 1 or 2 cytokine release syndromes (CRS), immune effector cell-associated neurotoxicity syndrome (ICANS), and immune effector cell-associated HLH-like syndromes (IEC-HS). This interview took place during the 2024 American Society of Clinical Oncology (ASCO) Meeting in Chicago, IL.
