Treatment-Related Cost Analysis of Terlipressin for Adults with Hepatorenal Syndrome with Rapid Reduction in Kidney Function

Abstract

Introduction Hepatorenal syndrome (HRS), a special form of acute kidney failure, is a rare, acute, life-threatening complication of cirrhosis and has a very poor prognosis. Terlipressin (TERLIVAZ ® ) is the first and only pharmacological treatment approved by Food and Drug Administration (September 2022) to improve kidney function for adults with HRS with rapid reduction in kidney function. We constructed a decision analytic economic model to estimate the cost per complete response/HRS reversal of terlipressin + albumin from a United States hospital perspective. Methods A decision analytic model was developed to estimate the HRS treatment-related cost per response over an HRS hospitalization (assuming 14 days). Patients can experience either HRS reversal (complete response) or no HRS reversal (partial/no response) upon receipt of treatment. The efficacy, safety, and treatment duration data were from published head-to-head randomized international trials. Total treatment cost comprised drug acquisition and treatment-related costs (intensive care unit [ICU], dialysis [intermittent or continuous], pulse oximetry monitoring for terlipressin, and adverse events) sourced from the published literature. Cost per response, defined as the total treatment cost per HRS reversal was estimated for each treatment. The number needed to treat (NNT), defined as the number of patients treated to achieve HRS reversal in 1 additional patient, was estimated. Results Cost per response of terlipressin + albumin was lower than midodrine and octreotide + albumin (M&O) (US$85,315 vs. $467,794) and norepinephrine + albumin ($81,614 vs. $139,324). NNT for HRS reversal was 2 patients with terlipressin + albumin vs. M&O + albumin and 4 patients with terlipressin + albumin vs. norepinephrine + albumin, respectively. Conclusions The analysis shows that terlipressin is a cost-effective treatment due to its higher efficacy and administration in the non-ICU setting. Terlipressin is a value-based treatment option for appropriate adults with HRS with rapid reduction in kidney function.
