Abstract:
:With several different CAR T cell therapies under advanced phases of clinical trials, and the first FDA-approved CAR treatments in 2017 (Yescarta and Kymriah), CAR T cell therapy has become one of the most promising therapies for the treatment of certain types of cancer. This success has bred an opportunity to optimize the production of CAR T cells for easier patient access. CAR T cell therapy is a rather expensive and personalized process that requires expensive measures to collect cells from patients, engineer those cells, and re-infuse the cells into the patient with adequate quality controls at each phase. With this in mind, significant attempts at creating a "universal" CAR T cell are underway in order to create an "off-the-shelf" product that would reduce the expense and time required for traditional CAR T cell treatment. The primary obstacle facing this endeavor is avoiding graft-versus-host disease that accompanies allogeneic transplants between genetically dissimilar individuals. With the advent of CRISPR and TALEN technology, editing the genome of allogeneic cells has become very possible, and several groups have provided initial data analyzing the effects of CAR T cells that have been edited to avoid host rejection and avoid endogenous TCR alloreactivity. These engineered cells not only have to avoid GVHD but also have to retain their anti-tumor efficacy in vivo. Here, we expand on the recent efforts and strides that have been made in the design and testing of universal allogeneic CAR T cells.
