— Terlipressin CONFIRM Phase 3 Trial Enrolls 75th Patient of 300-Patient Target Enrollment; Marks Halfway Point toward Interim Analysis of Trial Data —

STAINES-UPON-THAMES, UK, USA I July 13, 2017 I Mallinckrodt plc (NYSE: MNK), a leading global specialty pharmaceutical company, today announced it has enrolled the 75th subject in the company’s ongoing Phase 3 pivotal trial CONFIRM to evaluate the efficacy and safety of terlipressin (for injection) in subjects with Hepatorenal Syndrome (HRS) type 1.

Phase 3 trial enrollment has been robust and the company has achieved one quarter of its targeted enrollment for this trial aligned with the company’s expectations. Additionally, an important interim analysis of trial data to assess the safety and efficacy of terlipressin in study subjects will be completed when 150 subjects are enrolled and this also marks the halfway point toward that milestone.

Terlipressin is being investigated for the treatment of HRS type 1, an acute, rare and life-threatening condition requiring hospitalization, with currently no approved therapy in the U.S. or Canada. The safety and efficacy of terlipressin for the treatment of HRS type 1 has not been established with the U.S. Food and Drug Administration or Health Canada.  Terlipressin is approved for use in countries outside the U.S., including Europe, Latin America, Asia and Australia1,2,3,4.

The interim analysis has been approved under the Special Protocol Assessment agreed upon with the U.S. Food and Drug Administration. Though it sets a high hurdle for determining safety and efficacy of the study drug, it also allows for potential early termination of the study. Given the known profile of terlipressin in many countries for this patient population, and the unmet need in HRS type 1 in the U.S. and Canada, Mallinckrodt looks forward to the results of the interim analysis.

“Mallinckrodt is committed to advancing therapies for patients with rare diseases and critical conditions who have limited treatment options such as those suffering from HRS type 1,” said Steven Romano, M.D., Chief Scientific Officer and Executive Vice President at Mallinckrodt. “We are pleased to reach this important milestone in the terlipressin CONFIRM trial, and look forward to learning more about how the drug can help patients with this serious condition.”

About Hepatorenal Syndrome
HRS is characterized by rapid, progressive functional renal failure and has a very poor prognosis, with >80 percent mortality within three months. HRS is a rare syndrome of marked renal dysfunction in patients with cirrhosis, decompensated liver disease and portal hypertension. At present, there are no approved drug therapies for HRS type 1 in the U.S. or Canada. The only curative treatment for HRS type 1 and the underlying end-stage cirrhosis is liver transplantation. However, many patients will not survive long enough to receive a liver transplant.

Terlipressin is a synthetic vasopressin analogue being investigated for the treatment of HRS type 1 in the U.S. and Canada. Safety and efficacy has not been established with nor has approval been granted by regulatory authorities in either country.
