The OPsumit® Historical USers cohort (OrPHeUS) study was conducted to supplement the OPUS data with additional new macitentan users.Aims and Objectives: To describe patient characteristics, treatment patterns, hepatic safety and survival in PH patients newly treated with macitentan in OPUS/OrPHeUS.Methods: OPUS is an ongoing, prospective, multicentre, long-term, observational drug registry (NCT02126943). OrPHeUS was a retrospective, multicentre medical chart review (NCT03197688). Here we describe patients with follow-up data in OPUS/OrPHeUS.Results: By Oct 2018, the combined OPUS/OrPHeUS population consisted of 5070 patients, of which 4979 had follow-up data. At macitentan initiation, median (Q1, Q3) age was 62 (51, 71) years and 2926 (58.8%) were on background pulmonary arterial hypertension therapy. WHO functional class (FC) was assessed in 2085 (41.9%) patients; 37.4% of those were in FC I/II and 62.6% in FC III/IV. Median (Q1, Q3) exposure to macitentan was 13.2 (4.6, 26.1) months. Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≥3x upper limit of normal (ULN) were experienced by 162 (3.3%) patients (incidence rate (IR): 0.025 [95% CI, 0.021, 0.029] per 1 person-year); ALT/AST ≥x3 ULN and bilirubin ≥2x ULN was experienced by 39 (0.8%) patients (IR: 0.006 [95% CI, 0.004, 0.008] per 1 person-year). The 12-month Kaplan-Meier survival estimate was 92% (95% CI, 91, 93).Conclusions: This is the largest data set of PH patients newly treated with macitentan and confirms the hepatic safety profile of macitentan with no unexpected safety findings.FootnotesCite this article as: European Respiratory Journal 2019; 54: Suppl. 63, PA5458.This is an ERS International Congress abstract.
