Rhea-AI Summary

Mallinckrodt presents findings from clinical studies and health economic analysis of TERLIVAZ for hepatorenal syndrome treatment outcomes at ACG Annual Scientific Meeting

Positive

• TERLIVAZ is the first FDA-approved product to improve kidney function in adults with HRS, a life-threatening condition requiring hospitalization

Negative

• None.

– Findings from two clinical studies and one health economic database analysis provide insight into HRS treatment outcomes with TERLIVAZ,¹ patients' cardiac health² and association between hospital size and overall outcomes for chronic liver disease patients³ –

DUBLIN, Oct. 22, 2023 /PRNewswire/ -- Mallinckrodt plc (OTCMKTS: MNKTQ), a global specialty pharmaceutical company, today announced that three posters detailing findings from Mallinckrodt's latest clinical and health economics outcomes research with TERLIVAZ^® (terlipressin) for injection for adult patients with hepatorenal syndrome (HRS) with rapid reduction in kidney function^1,2,3,4 will be presented at the American College of Gastroenterology (ACG) Annual Scientific Meeting in Vancouver, British Columbia, taking place October 20-25, 2023.

TERLIVAZ is the first and only FDA-approved product indicated to improve kidney function in adults with HRS with rapid reduction in kidney function,⁴ an acute and life-threatening condition requiring hospitalization.⁵ TERLIVAZ is not approved in Canada.

Please see Limitation of Use and Important Safety Information, including Boxed Warning, below.

Paul J. Thuluvath, MD, will present findings from a pooled analysis of Mallinckrodt's three prospective, randomized, placebo-controlled clinical studies in patients with HRS (OT-0401, REVERSE, and CONFIRM) to examine whether there was any impact of race (White vs. non-White) on treatment response to TERLIVAZ.¹ HRS reversal – defined as the proportion of patients achieving a serum creatinine level of ≤ 1.5 mg/dL while on treatment including up to 24 hours after the last dose of study drug – was examined by race and assessed for the potential to predict treatment response.¹

A post-hoc analysis of the Phase III CONFIRM trial – which evaluated maximum change and time of maximum change in mean arterial pressure (MAP), heart rate (HR) and systolic and diastolic blood pressure (SBP and DBP) with TERLIVAZ treatment – will be presented by Jacqueline G. O'Leary, MD.² The data were analyzed to monitor for significant changes in MAP, SBP and DBP between treatment groups, and to determine the associated level of required cardiac monitoring.²

Additionally, results from a real-world analysis of the impact of hospital size on patient outcomes among those with chronic liver disease (CLD) and acute kidney injury or HRS will be presented by Ronald J. Wong, MD.³ This analysis identified nearly 3 million hospitalized patients with CLD (including cirrhosis) from 2016-2022 using the Premier Healthcare Database inclusive of over 1,041 hospitals/health systems in the U.S., to assess overall outcomes of treatment such as in-hospital mortality and comorbidity for patients in hospitals of varying sizes.³

Additional information on these studies can be found below.

"These data presentations not only deepen our understanding of how HRS patient baseline characteristics – and their response to therapy – impact treatment outcomes with TERLIVAZ, but also lend insight into how the critical care setting in which patients are hospitalized affects their treatment journey in the real world,"^1,2,3 said Khurram Jamil, Vice President, Hepatology, Clinical Development & Critical Care. "We are pleased to share this data with the gastroenterology community and remain steadfast in our mission to conduct clinical and health economic research to better support and inform the care decisions of physicians managing these critically ill patients."

These studies are sponsored by Mallinckrodt Pharmaceuticals and include:

INDICATION AND LIMITATION OF USE

TERLIVAZ^® is indicated to improve kidney function in adults with hepatorenal syndrome with rapid reduction in kidney function.

• Patients with a serum creatinine >5 mg/dL are unlikely to experience benefit.

IMPORTANT SAFETY INFORMATION

WARNING: SERIOUS OR FATAL RESPIRATORY FAILURE

• TERLIVAZ may cause serious or fatal respiratory failure. Patients with volume overload or with acute-on-chronic liver failure (ACLF) Grade 3 are at increased risk. Assess oxygenation saturation (e.g., SpO₂) before initiating TERLIVAZ.

• Do not initiate TERLIVAZ in patients experiencing hypoxia (e.g., SpO₂ <90%) until oxygenation levels improve. Monitor patients for hypoxia using continuous pulse oximetry during treatment and discontinue TERLIVAZ if SpO₂ decreases below 90%.

Contraindications

TERLIVAZ is contraindicated:

• In patients experiencing hypoxia or worsening respiratory symptoms.
• In patients with ongoing coronary, peripheral, or mesenteric ischemia.

Warnings and Precautions

• Serious or Fatal Respiratory Failure: Obtain baseline oxygen saturation and do not initiate TERLIVAZ in hypoxic patients. Monitor patients for changes in respiratory status using continuous pulse oximetry and regular clinical assessments. Discontinue TERLIVAZ in patients experiencing hypoxia or increased respiratory symptoms.

Manage intravascular volume overload by reducing or discontinuing the administration of albumin and/or other fluids and through judicious use of diuretics. Temporarily interrupt, reduce, or discontinue TERLIVAZ treatment until patient volume status improves. Avoid use in patients with ACLF Grade 3 because they are at significant risk for respiratory failure.

• Ineligibility for Liver Transplant: TERLIVAZ-related adverse reactions (respiratory failure, ischemia) may make a patient ineligible for liver transplantation, if listed. For patients with high prioritization for liver transplantation (e.g., MELD ≥35), the benefits of TERLIVAZ may not outweigh its risks.

• Ischemic Events: TERLIVAZ may cause cardiac, cerebrovascular, peripheral, or mesenteric ischemia. Avoid use of TERLIVAZ in patients with a history of severe cardiovascular conditions or cerebrovascular or ischemic disease. Discontinue TERLIVAZ in patients who experience signs or symptoms suggestive of ischemic adverse reactions.

• Embryo-Fetal Toxicity: TERLIVAZ may cause fetal harm when administered to a pregnant woman. If TERLIVAZ is used during pregnancy, the patient should be informed of the potential risk to the fetus.

Adverse Reactions

• The most common adverse reactions (≥10%) include abdominal pain, nausea, respiratory failure, diarrhea, and dyspnea.

About Hepatorenal Syndrome (HRS)
Hepatorenal syndrome (HRS) involving rapid reduction in kidney function⁴ is an acute and life-threatening condition that occurs in people with advanced liver disease.⁵ 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.⁵ HRS involving rapid reduction in kidney function⁴ is estimated to affect between 30,000 and 40,000 Americans annually.^6,7 If left untreated, HRS with rapid reduction in kidney function⁴ has a median survival time of approximately two weeks and greater than 80 percent mortality within three months.⁸
