The FDA previously placed two clinical studies on hold, including the Phase III trial in which the liver toxicity occurred. Intellia is working with experts to create a risk management program for nex-z.
Pfizer and Novo Nordisk continue to fight for ownership of obesity startup Metsera; CDER Director George Tidmarsh leaves his position amid an ongoing probe into his “personal conduct”; FDA reverses course on approval requirements for uniQure’s Huntington’s gene therapy; Sarepta’s exon-skipping Duchenne muscular dystrophy drugs fail confirmatory study.
The potential approval of Vertex’s IgAN therapy povetacicept in 2026 comes amid launch headwinds for the company’s non-opioid pain medicine Journavx and gene therapy Casgevy.
The clinical hold comes days after Intellia voluntarily paused enrollment and dosing in the same two studies.
