The starting problem
Tumor suppression
Multiple signals converge on the same T cell.
Activity can decline.Our Science
Solid tumors use multiple pathways to shut down CAR-T cells. We combine protections within the same cell to help it keep working.

Why activity fades
GBM shuts them down through overlapping signals.
Block one signal, others remain.
KiraGen’s approach
The starting problem
Multiple signals converge on the same T cell.
Activity can decline.Common approach

Cytokine armoring or removing internal activity brakes
Can increase toxicity risk.Common approach

TGF-β or PD-1 blockade
Other suppressive signals remain.KiraGen’s approach

Multiplex gene editing
Designed for sustained activity.Why now
