Mallinckrodt plc issued the following announcement on July 15.
- If approved, terlipressin would be the first FDA-approved treatment in the United States for adult patients with HRS-1, a life-threatening condition -
- Prescription Drug User Fee Act (PDUFA) target action date is September 12 -
Mallinckrodt plc (NYSE: MNK), a global biopharmaceutical company, today announced that the Cardiovascular and Renal Drugs Advisory Committee of the U.S. Food and Drug Administration (FDA) voted to recommend approval for its investigational agent terlipressin to treat adults with hepatorenal syndrome type 1 (HRS-1) (8 yes; 7 no). HRS-1 is an acute and life-threatening syndrome involving acute kidney failure in people with cirrhosis.1 Terlipressin is an investigational agent being evaluated for the treatment of HRS-1 in the U.S., and its safety and effectiveness have not yet been established by the FDA.
"Mallinckrodt is pleased with the advisory committee's positive vote in favor of approval for terlipressin, supporting the potential clinical value terlipressin can bring to patients with HRS-1 in need of an approved therapy in the U.S.," said Steven Romano, M.D., Executive Vice President and Chief Scientific Officer at Mallinckrodt. "We acknowledge the clinical challenges associated with treating this complex disease in such a critically ill patient population. We are committed to working closely with the FDA as it continues to review our application."
HRS-1 requires a diagnosis of exclusion, and is often a challenge to diagnose in a timely manner.2 If left untreated, HRS-1 has a median survival time of approximately two weeks and greater than 80 percent mortality within three months.2,3 At present, there are no approved drug therapies for HRS-1 in the U.S.,4 and it is estimated to affect between 30,000 and 40,000 Americans annually.5,6
"Terlipressin plus albumin is the recommended standard-of-care therapy for HRS-1 in many other countries, where terlipressin is approved," said Francois Durand, M.D., on behalf of the International Club of Ascites. "HRS-1 is one of the most severe complications of end stage liver disease and the favorable vote from the advisory committee is encouraging to U.S. patients in need of treatment."
While recommendations of the advisory committee are not binding, the FDA will consider the advice provided by the committee as part of the New Drug Application (NDA) review. The FDA assigned terlipressin a Prescription Drug User Fee Act (PDUFA) target date of September 12, 2020. The company announced the FDA accepted for review its NDA for terlipressin in April 2020, which was based, in part, on results from the Phase 3 CONFIRM trial. The CONFIRM trial was the largest-ever prospective study (n=300) conducted to assess the safety and efficacy of terlipressin in patients with HRS-1, for potential use in the U.S. and Canada. Initial results were presented at The Liver Meeting® 2019, the annual meeting of the American Association for the Study of Liver Diseases (AASLD).
