Phase 1/2b Trial of Autologous Humanized CD19-Directed Chimeric Antigen Receptor T-Cells Manufactured Using the CliniMACS Prodigy Platform for the Treatment of Pediatric B Cell Acute Lymphoblastic Leukemia (B-ALL)
Stephan Grupp MD PhD
Summary
This study will determine the safety and efficacy of moving to a second-generation manufacturing process using the CliniMACS Prodigy platform to manufacture huCART19 cells for patients with B cell Acute Lymphoblastic Leukemia (B-ALL).
Description
Chimeric Antigen Receptor T-Cells (CAR T) cell therapy has shifted the treatment landscape for pediatric and young adult patients with multiply relapsed and refractory B-ALL (B cell Acute Lymphoblastic Leukemia), however, the manufacturing process remains in its first generation: laborious, time-intensive, and not automated. The time and significant personnel resources in this process can result in patient safety issues - with patients growing sicker, with harder to control leukemias - in the waiting period between T cell collection and completed CAR T cell product manufacture. Use of the Clin…

Interventions
- BiologicalAutologous Humanized CD19-Directed Chimeric Antigen Receptor T-Cells (huCART19)
The investigational agent in this protocol is humanized CART19 cells (huCART19). Autologous T cells will be engineered to express an extracellular single chain antibody (scFv) with specificity for CD19. This will be expected to redirect specificity of the transduced T cells for cells that express CD19, a molecule that is restricted in expression on the surface of the malignant cells and on normal B cells.
