The Nex-Z Trial – A CRISPR-Cas9 Based Treatment for ATTR Cardiac Amyloidosis with Dr. Ronald Witteles

Join CardioNerds Heart Failure Section Chair Dr. Jenna Skowronski, episode lead Dr. Apoorva Gangavelli, and expert faculty Dr. Ronald Witteles as they discuss the Nex-Z trial.


This was a phase 1, open-label trial investigating nex-z, a CRISPR-Cas9-based treatment, in 36 patients with transthyretin amyloidosis with cardiomyopathy (ATTR-CM). The primary objectives were aimed at studying the safety and pharmacodynamics of this novel gene-based treatment modality. This episode dives into the nuances of the data, future directions for investigation, and future clinical implications.
