Intellia Therapeutics (NTLA) reported an FDA clinical hold on the Investigational New Drug applications for its MAGNITUDE and MAGNITUDE‑2 Phase 3 trials of nexiguran ziclumeran (nex‑z). The company was verbally informed on October 29, 2025, and the FDA indicated it will issue a formal Clinical Hold Letter within 30 calendar days.

The hold follows a previously disclosed patient case with Grade 4 liver transaminases and increased total bilirubin in the MAGNITUDE trial.

Intellia Therapeutics temporarily paused dosing and screening in its Phase 3 MAGNITUDE (ATTR-CM) and MAGNITUDE-2 (ATTRv-PN) trials of nexiguran ziclumeran (nex-z) after a safety event met protocol-defined pausing criteria.

The action follows an October 24 report of Grade 4 liver transaminases and increased total bilirubin in a patient dosed on September 30 in MAGNITUDE. More than 650 patients with ATTR-CM are enrolled in MAGNITUDE and 47 patients with ATTR-PN are enrolled in MAGNITUDE-2; over 450 patients are estimated to have been dosed with nex-z. The company furnished a press release as Exhibit 99.1 and included standard forward-looking statements regarding the ability to resume and complete these studies.
