MaxCyte® Inc., the pioneer in cell therapies using scalable, high-performance cell transfection systems, today announces a strategic research collaboration with Johns Hopkins University (JHU) to develop unique Chimeric Antigen Receptor (CAR) T-cell therapies, which harness patients’ own immune systems to combat cancers.
MaxCyte’s unique approach to CAR cell therapy allows targeting of solid tumor cancers by enabling control over the on-target, off-tumor toxicity, which limits other CAR therapies to hematological cancers. MaxCyte achieves this by introducing the CAR construct as a transiently expressing messenger RNA (mRNA), thus allowing control of the duration of expression and toxicity against target antigens in normal tissue. This unique approach also avoids the cell expansion step required for standard approaches, dramatically reducing manufacturing time and expense for CAR therapies from days or weeks to a matter of hours.
