The dominant risk is not whether
Prime Editing is intellectually interesting; it is whether Prime can finance the bridge to repeatable human proof in liver disease without giving away too much value. The next layer of risk is transferability:
PM359 lowered modality skepticism, but it did not prove that
in vivo liver delivery, safety, and durability will work in humans at commercial quality. Regulatory friction,
AATD rights uncertainty, and a concentrated
pipeline keep the path fragile.
