ASH: Another 'off-the-shelf' cell therapy leader shows durability issues, raising renewed concerns about emerging field
The next generation of cell therapies have focused in large part on the development of allogeneic — better known as “off-the-shelf — drugs that can cut manufacturing times and hopefully evade a patient’s immune system. One of the early players in that race has new data at #ASH21 that show deep responses but will also raise fresh concerns about these therapies’ durability.
Precision Biosciences’ PBCAR0191, a CD19-directed allogeneic CAR-T cell therapy, posted a complete response rate of 59% in 22 heavily pretreated patients with various forms of relapsed or refractory non-Hodgkin’s lymphoma and acute lymphocytic leukemia, six of whom had previously received an autologous CAR-T before dosing, the biotech said.
