Overcoming B-ALL With Enhanced CAR T Manufacturing

Published on Feb 10, 2025 Share

B cell acute lymphoblastic leukemia (B-ALL) is an aggressive cancer affecting the bone marrow and blood. When traditional treatments like chemotherapy and radiation fall short in relapsed or refractory cases, CAR T cell therapy provides a transformative new option, offering hope via T cells engineered to target and destroy cancerous B cells.

At Akadeum Life Sciences, our innovative cell isolation technologies, including the Alerion^TM Microbubble Cell Separation System and our microbubble T cell isolation kits, optimize CAR T manufacturing by providing a scalable solution that also enhances cell purity and yield while maintaining viability. Let’s explore B-ALL and how Akadeum’s solutions enhance CAR T therapy.

Understanding B Cell Acute Lymphoblastic Leukemia

B-ALL is a type of blood cancer characterized by the rapid growth of immature B cells, or lymphoblasts, within bone marrow. These malignant cells crowd out healthy blood cells, resulting in compromised immune function and other serious complications. While B-ALL is most commonly diagnosed in children, adults can also develop the disease, often with different treatment challenges and outcomes.

Prognosis and Treatment of B-ALL

The prognosis of B cell acute lymphoblastic leukemia has significantly improved, especially in children,  thanks to treatment advances over several decades. Survival rates have risen to around 85% in children and 40% in adults, depending on factors like age and genetic markers.

However, relapsed or refractory B-ALL remains a significant challenge, highlighting the need for advanced treatments like CAR T cell therapy. This innovative approach involves engineering a patient’s T cells to target and eliminate malignant B cells, offering renewed hope for those who have exhausted conventional options.

CAR T Cell Therapy: A Breakthrough in B-ALL Treatment

CAR T cell therapy is a paradigm shift in cancer treatment, particularly for B-ALL. Clinical scientists collect T cells and genetically modify them to express chimeric antigen receptors (CARs) on their surface that target specific proteins on malignant B cells. These enhanced cells are then infused back into the patient where they will precisely target and eliminate cancerous B cells.

Overall, CAR T immunotherapy demonstrates remarkable efficacy in treating relapsed or refractory B-ALL, including high remission rates in patients with limited options. This success cements CAR T cell therapy as a leading option for improving outcomes for this aggressive form of leukemia. As of 2024, the FDA has approved two CAR T therapies for treating relapsed or refractory B-ALL.

Challenges in CAR T Cell Manufacturing

CAR T cell therapy is a complex treatment that requires meticulous manufacturing processes. One of the critical steps is isolating and preparing T cells from patient samples. Cells must remain viable, functional, and uncontaminated, as any compromise reduces effectiveness.

A key challenge is the variability in leukapheresis samples, which can contain a heterogeneous cell sample. Isolating the T cells with high purity and yield is essential for the success of CAR T therapy. 

The Role of Cell Isolation in CAR T Therapy

Cell isolation is the cornerstone of CAR T manufacturing. It ensures that only high-quality, viable T cells are used for engineering, thereby improving the therapeutic potential of the final product. Akadeum’s innovative solutions in this area significantly reduce the time and cost associated with manufacturing, a crucial factor for patients with aggressive diseases like B-ALL.

Akadeum’s Innovations in Cell Separation for CAR T Therapy

Akadeum’s Alerion^TM Microbubble Cell Separation System is a game-changer for isolating T cells, providing researchers with a closed system capable of processing 40 billion cells in less than an hour. Unlike harsh mechanical or magnetic methods, microbubbles provide a gentle, buoyancy-based approach that preserves cell viability and functionality. This aspect is critical for CAR T therapy, where the quality of isolated cells impacts treatment success.

Key Products for CAR T Manufacturing

• Human T Cell Leukopak Isolation Kit. The Human T Cell Leukopack Isolation Kit efficiently isolates T cells directly from leukapheresis samples, offering high purity and recovery rates while reducing processing time.
