Dr. Ghosh on the Role of Off-the-Shelf CAR T-Cell Therapy in Myeloma


Monalisa Ghosh, MD, discusses the role of off-the-shelf CAR T-cell therapy in patients with multiple myeloma.

Monalisa Ghosh, MD, a clinical assistant professor at the University of Michigan, discusses the role of off-the-shelf CAR T-cell therapy in patients with multiple myeloma.

These products are promising in many ways and provide several advantages, including a decreased manufacturing time, Ghosh says. Experts in the field can request and receive off-the-shelf CAR T-cell products from a bank, she explains. This eliminates the need to wait for patient cell collection, which puts the patient at some degree of risk, and decreases the manufacturing time that ordinarily takes several weeks. The decreased treatment timeline can also be beneficial to patients with rapidly progressive disease, Ghosh notes.

However, challenges exist with this therapy, as allogenic cells may cause certain adverse effects, such as a graft-versus-host reaction that is similar to reactions observed with stem cell transplantation, Ghosh says. Currently, certain methods of T-cell receptor engineering may be able to mitigate this risk, she adds. Additionally, some hosts may reject the cells, a possibility that has been observed in early studies, wherein cells have not demonstrated long-term persistence. It may be possible to overcome this through multiple cell infusions, Ghosh notes.

Overall, the accessibility of off-the-shelf CAR T-cell products to a large group of patients with multiple myeloma appears promising, Ghosh concludes.
