Clinical research
Being tested in people in registered clinical trials. Being in trials is not evidence that a treatment works or is safe.
この試験で検証していること
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.

初期段階の結果は少人数の参加者と短い追跡期間から得られたものです。参加者が増え時間が経つにつれて変わる可能性があり、募集中・実施中・完了済みの試験であっても、治療効果が確立されたわけではありません。登録基準は厳格で、適格性の判断は試験実施施設が行うものであり、ウェブサイトが行うものではありません。
