CRISPR therapy takes on rare swelling disorder

NCT ID NCT06634420

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 3 trial tests a one-time gene editing treatment called NTLA-2002 for people with hereditary angioedema (HAE), a rare genetic condition causing sudden, painful swelling attacks. About 80 participants will receive either the treatment or a placebo. The goal is to see if NTLA-2002 can reduce the number of attacks by targeting the root genetic cause.

What this could mean

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

Active substance

NTLA-2002 (a gene editing therapy using CRISPR/Cas9 delivered via lipid nanoparticles)

What this could lead to

If it works, this could provide a long-lasting reduction in HAE attacks, potentially freeing patients from regular preventive medications.

What could go wrong

This is still an early-stage trial with only 80 participants. The treatment may not work for everyone, and long-term safety is unknown. Gene editing carries risks like unintended genetic changes.
