– Findings from two clinical study presentations in adults with HRS involving rapid reduction in kidney function1 provide insight into the appropriate use of terlipressin for the care of critically ill patients2,3 –
DUBLIN, May 8, 2023 /PRNewswire/ -- Mallinckrodt plc (NYSE American: MNK), a global specialty pharmaceutical company, today announced the presentation of results from two clinical studies for adults with hepatorenal syndrome (HRS) with rapid reduction in kidney function1 treated with TERLIVAZ® (terlipressin) for injection at Digestive Disease Week® (DDW) 2023, taking place in Chicago, Ill. from May 6-9. Mallinckrodt's pooled analysis of three North American Phase III studies on the incidence of adverse events (AEs) related to bradycardia and arrhythmias in adults with HRS treated with terlipressin was awarded Poster of Distinction status from DDW, and was presented on Sunday, May 7, 2023, 12:30 – 1:30 p.m. CDT.2 Additionally, Mallinckrodt's subgroup analysis of the CONFIRM Phase III study to assess terlipressin treatment outcomes in adults with HRS compounded by alcoholic hepatitis (AH) will be presented in an oral lecture session today, May 8, 2023, 10:30 – 10:45 a.m. CDT.3
TERLIVAZ is the first and only FDA-approved product indicated for the treatment of adults with HRS involving rapid reduction in kidney function,1 an acute and life-threatening condition requiring hospitalization.4 Terlipressin is recommended by the American Association for the Study of Liver Diseases (AASLD) guidance5 and the American College of Gastroenterology (ACG) guidelines.6
Please see Limitation of Use and Important Safety Information, including Boxed Warning, below.
Presented by Jasmohan S. Bajaj, School of Internal Medicine, Virginia Commonwealth University, Richmond, Va., the pooled analysis (DDW Poster of Distinction: Su1535) used the largest-to-date prospective database of three North American Phase III, randomized, placebo-controlled trials (OT-0401, REVERSE, CONFIRM) to evaluate the incidence of reported bradycardia and arrhythmias in adult patients with HRS treated with terlipressin vs. placebo. All three studies excluded patients with prior arrhythmias and significant cardiovascular disease, and statistical analysis was determined using a Fisher's Exact test.2
Khurram Jamil, Vice President & Head, Hepatology, Clinical Development & Critical Care at Mallinckrodt, said, "We are excited to share the results from this pooled analysis of the largest HRS patient data set to-date, selected as a DDW 2023 Poster of Distinction, which bolsters our overall understanding of TERLIVAZ® (terlipressin) for injection's risk-benefit profile and the significance of adverse events such as bradycardia and arrhythmias,2 to ultimately provide continued support for the use of this treatment in appropriate patients with HRS with rapid reduction in kidney function.1"
The pooled safety population included 598 patients, of which 349 received terlipressin and 249 received placebo. The incidence of episodes of bradycardia was higher in terlipressin-treated patients (6.3%; n=22) compared with placebo-treated patients (0.8%; n=2; P<0.001), and none of these episodes were considered serious. Bradycardia was classified as severe per investigator assessment in 68.2% (n=15/22) of patients in the terlipressin group and in 100% (n=2/2) of patients in the placebo group, and most patients did not require a change in treatment dose (terlipressin: 72.7%; n=16/22 vs. placebo: 50%; n=1/2; P=0.507). One patient treated with terlipressin had a dose interruption, and there were no treatment discontinuations.2
Further, no differences were observed between treatment groups (terlipressin: arrhythmia [0%, n=0/349,]; nodal arrhythmia [0%, n=0/349]; ventricular fibrillation [0%, n=0/349] vs. placebo: arrhythmia [0.8%, n=2/249, P=0.173]; nodal arrhythmia [0.4%, n= 1/249, P=0.416]; ventricular fibrillation [0.4%, n=1/249, P=0.416]. Atrial fibrillation was the most reported arrhythmia across the pooled safety population (total: 4.0%, n=24/598; terlipressin: 3.7%, n=13/349; placebo: 4.4%, n=11/249; P=0.678).2
To be presented by Kevin Korenblat, Washington University School of Medicine, St. Louis, Mo., the key findings of a subgroup analysis (DDW Oral Lecture: 651) of the CONFIRM Phase III study aim to evaluate efficacy of terlipressin treatment in patients with HRS compounded by AH. Diagnosis of baseline AH was via investigator assessment, and data was retrospectively analyzed in patients with AH for verified HRS reversal (defined as the percentage of patients with 2 serum creatinine (SCr) values of ≤1.5 mg/dL ≥2 hours apart, while on treatment up to 72 hours after the last dose of study drug), admission to the intensive care unit (ICU), length of ICU stay, and incidence of renal replacement therapy (RRT) by Day 30.3
"The findings of this subgroup analysis of the CONFIRM Phase III study build upon the growing body of evidence supporting the use of TERLIVAZ® (terlipressin) for injection as a treatment option among critical care patients with HRS, including its therapeutic ability to drive meaningful clinical outcomes for a significant population of patients with comorbid conditions, such as alcoholic hepatitis,3" added Peter Richardson, MRCP (UK), Executive Vice President & Chief Scientific Officer at Mallinckrodt. "As TERLIVAZ uptake and use among U.S. hospitals continues following FDA approval in 2022, our research at DDW 2023 reflects our ongoing commitment to critically ill patients by pursuing research that provides physicians with the most up-to-date treatment considerations to help inform patient care decisions."
In CONFIRM (n=300), 41% (81/199) of patients in the terlipressin group and 39% (39/101) of the patients in the placebo group had AH at baseline. In the subgroup of patients with AH (n=120), the median Maddrey discriminant function score was similar across treatment groups (terlipressin: 96.9 vs. placebo: 97.7; P=0.681). Verified HRS reversal was achieved in 30.9% (n=25/81) of patients in the terlipressin group vs. 7.7% (n=3/39) in the placebo group (P=0.005).3
Additionally, admission to the ICU was similar for patients in the terlipressin and placebo groups (17.3%, n=14 vs. 17.9%, n=7), whereas mean length of stay in the ICU was shorter for terlipressin (6.9 days) vs. the placebo group (12.4 days). There was a numerical decrease in RRT by Day 30 in the terlipressin group vs. the placebo group (21%, n=17 vs. 25.6%, n= 10).3

About Hepatorenal Syndrome (HRS)
Hepatorenal syndrome (HRS) involving rapid reduction in kidney function1 is an acute and life-threatening condition that occurs in people with advanced liver disease.4 HRS is classified into two distinct types – a rapidly progressive type that leads to acute renal failure where patients are typically hospitalized for their care and a more chronic type that progresses over weeks to months.4 HRS involving rapid reduction in kidney function1 is estimated to affect between 30,000 and 40,000 Americans annually.7,8 If left untreated, HRS with rapid reduction in kidney function1 has a median survival time of approximately two weeks and greater than 80 percent mortality within three months.9
INDICATION AND LIMITATION OF USE
TERLIVAZ is indicated to improve kidney function in adults with hepatorenal syndrome with rapid reduction in kidney function.
