Frequently asked questions about NTZ

What is NTZ?

NTZ is an investigational small molecule drug being developed by Genfit SA (ticker GNFT) for acute decompensation of liver cirrhosis. It is given at 500 mg twice daily on top of standard of care. NTZ is currently in Phase 2 clinical development and is not yet approved for any indication.

What is NTZ used for in acute decompensation of liver cirrhosis?

NTZ is being studied for use in patients with acute decompensation of liver cirrhosis who are at high risk of progressing to acute-on-chronic liver failure, or who already have established acute-on-chronic liver failure. It is added to standard of care at a dose of 500 mg twice daily. It remains investigational.

Who is developing NTZ?

NTZ is being developed by Genfit SA, which trades under the ticker GNFT as a sponsored ADR. Genfit is the sponsor of the Phase 2 clinical study evaluating NTZ in patients with acute decompensation of liver cirrhosis.

What phase is NTZ in?

NTZ is in Phase 2 clinical development. The ongoing study is a Phase 2 trial in patients with acute decompensation of liver cirrhosis. NTZ has not completed any trials and is not approved; it remains an investigational drug.

What clinical trials is NTZ in?

NTZ is being evaluated in one Phase 2 clinical trial, NCT07694297, titled a Phase 2 study of 500 mg BID NTZ on top of standard of care in patients with acute decompensation of liver cirrhosis at high risk of progression to acute-on-chronic liver failure or established acute-on-chronic liver failure. The trial is not yet recruiting and plans to enroll 16 patients.
