CAR T-cell therapy has been a massive win against some of the toughest blood cancers. But there is a real sticking point. Every single treatment is a one-off, handcrafted from a patient's own cells. That process takes too long, costs far too much, and frankly, depends on the patient having T-cells strong enough for the job after they have already been through punishing therapies.

So, our goal has been to move from making these one-by-one to having them ready on the shelf. The intention with allogeneic therapy is to use cells from healthy donors to build a stockpile of a standardized, reliable treatment. This makes a powerful therapy available to patients in days, not weeks, at a fraction of the cost. Of course, the big question is safety—how do you stop the donor cells from attacking the patient? That is where the elegant part comes in. Using CRISPR gene-editing, we make one tiny, precise tweak: we just snip out the T-cell receptor. By removing that one piece, the new cells no longer see the patient's body as foreign, solving the graft-versus-host disease problem and making a universal therapy a reality.

This paper involves allogeneic CRISPR-engineered CAR T-cells that provide standardized, affordable, and ready-to-use cancer immunotherapy, overcoming delays, costs, and graft-versus-host limitations.
