Bio

Dr. Anne Marijn Kramer, MD, PhD, is a postdoctoral research fellow in the Division of Blood and Marrow Transplantation and Cellular Therapy at Stanford University. Dr. Kramer received her medical degree (with honors) from Amsterdam University in 2013. She conducted her PhD studies at University College London, studying binding kinetics of Chimeric Antigen Receptor (CAR) T cells. Her research at Stanford University focuses on developing methods to identify patients who are at high risk for relapse or developing side-effects after receiving CAR T therapy and to understand why these relapses and side-effects occur.

    Abstract

    Chimeric antigen receptor (CAR) T cells targeting CD22 (CD22-CAR) provide a therapeutic option for patients with CD22+ malignancies with progression after CD19-directed therapies. Using on-site, automated, closed-loop manufacturing, we conducted parallel Phase 1b clinical trials investigating a humanized CD22-CAR with 41BB costimulatory domain in children and adults with heavily treated, relapsed/refractory (r/r) B-ALL. Of 19 patients enrolled, 18 had successful CD22-CAR manufacturing, and 16 patients were infused. High grade (3-4) cytokine release syndrome (CRS) and immune effector-cell-associated neurotoxicity syndrome (ICANS) each occurred in only one patient; however, three patients experienced immune-effector-cell-associated hemophagocytic lymphohistiocytosis-like syndrome (IEC-HS). Twelve of 16 patients (75%) achieved CR with an overall 56% MRD-negative CR rate. Duration of response was overall limited (median 77 days), and CD22 expression was downregulated in 4/12 (33%) available samples at relapse. In summary, we demonstrate that closed-loop manufacturing of CD22-CAR T cells is feasible and is associated with a favorable safety profile and high CR rates in pediatric and adult r/r B-ALL, a cohort with limited CD22-CAR reporting.
