The FDA lifted a clinical hold on Intellia Therapeutics’ MAGNITUDE Phase 3 trial for its gene-editing therapy nexiguran ziclumeran in transthyretin amyloidosis with cardiomyopathy, following safety concerns in October 2025 involving elevated liver enzymes and bilirubin.
The company addressed the issues with enhanced liver monitoring, steroid use protocols, and patient exclusions.
The decision, effective March 2, 2026, allows the trial to resume, enrolling about 1,200 patients.
