Clinical research
Being tested in people in registered clinical trials. Being in trials is not evidence that a treatment works or is safe.
Ce que teste cet essai
A large late-stage trial testing whether a single infusion of a CRISPR treatment, which switches off a gene in the liver, helps people whose hearts are being damaged by amyloid deposits. In 2025 a participant died of liver failure after dosing; the trial was paused and placed on hold by the FDA, and the hold was later lifted.
A global Phase 3 study of nexiguran ziclumeran, a lipid-nanoparticle CRISPR-Cas9 therapy knocking out hepatic TTR, in participants with ATTR cardiomyopathy. Following a serious hepatic adverse event and death in a participant in his early eighties, Intellia voluntarily paused dosing and screening; the FDA imposed a clinical hold, which was subsequently lifted for this study.

Ce que signifie (et ne signifie pas) un résultat d'essai
Les résultats en phase précoce proviennent d'un petit nombre de participants et d'un suivi de courte durée. Ils peuvent évoluer avec davantage de personnes et de temps, et un essai en cours de recrutement, actif ou même terminé n'a pas établi qu'un traitement est efficace. Les critères d'inclusion sont stricts ; l'éligibilité est décidée par le site de l'essai, jamais par un site web.
