Gene Editing's lasting impact: a Long-Term look at NTLA-2001

NCT ID NCT05697861

First seen Aug 03, 2026 · Last updated Aug 04, 2026 · Updated 1 time

Summary

This study follows people who previously received NTLA-2001, an experimental gene-editing therapy, for a type of amyloidosis that can affect nerves or the heart. The goal is to monitor long-term safety and see if the therapy's effects on disease markers persist over time. Participants are observed without receiving new treatment, providing valuable data on the durability and potential risks of this one-time intervention.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
NTLA-2001, an investigational gene-editing therapy
What this could lead to
If successful, this follow-up could confirm that a single dose of gene-editing therapy provides lasting benefit and safety for people with ATTR amyloidosis.
What could go wrong
This is an observational follow-up, not a new treatment test. It cannot prove the therapy works, and long-term risks or loss of effect may still emerge.
