Clinical research
Being tested in people in registered clinical trials. Being in trials is not evidence that a treatment works or is safe.
O que este estudo está testando
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.

O que um resultado de estudo significa — e o que não significa
Resultados de fases iniciais vêm de um número pequeno de participantes e acompanhamento de curto prazo. Eles podem mudar com mais pessoas e mais tempo, e um ensaio que está recrutando, ativo ou até concluído ainda não estabeleceu que um tratamento funciona. Os critérios de inclusão são rigorosos; a elegibilidade é decidida pelo centro do ensaio, nunca por um site.
