Interim Analysis Shwed Treatment with OPSUMIT (macitentan) Assciated with Significant Imprvement in Right Ventricular (RV) Functin and Pulmnary Vascular Resistance (PVR) in Patients with Pulmnary Arterial Hypertensin (PAH) Actelin Presents REPAIR Study Interim Analysis at the American Cllege f Cardilgy's 68th Annual Scientific Sessin SOUTH SAN FRANCISCO, Calif. and ALLSCHWIL, Switzerland, March 15, 2019 /PRNewswire/ - - Actelin Pharmaceuticals US, Inc., ne f the Janssen Pharmaceutical Cmpanies f Jhnsn & Jhnsn, annunced tday an interim analysis frm the Right ventricular Remdeling in Pulmnary ArterIal hypertensin (REPAIR) study f OPSUMIT (macitentan) that shws treatment with OPSUMIT in patients with pulmnary arterial hypertensin (PAH) was assciated with significant imprvements in right ventricular (RV) functin including reversal f RV remdeling and reduced pulmnary vascular resistance (PVR). The data are being presented at the American Cllege f Cardilgy's 68th Annual Scientific Sessin. "The REPAIR study is the first multicenter study in PAH t use a primary endpint measured by cardiac MRI," said Stephan Rsenkranz, MD, Head f Pulmnary Hypertensin Center and Head f Clgne Cardivascular Research Center (CCRC), University f Clgne, Divisin f Cardilgy. "These results ffer clinicians wh treat this severe and prgressive disease a better understanding f the effects that macitentan can have n RV remdeling and functin in patients with PAH." The REPAIR study is a 52-week, pen-label, multicenter study evaluating the effect f OPSUMIT n RV remdeling and functin as determined by cardiac magnetic resnance imaging (MRI) and right heart catheterizatin. OPSUMIT was initiated as mntherapy r sequential cmbinatin therapy with a phsphdiesterase-type 5 (PDE-5) inhibitr r as initial cmbinatin therapy with a PDE-5 inhibitr. The pre-specified interim analysis including 42 patients with PAH shwed significant imprvements in bth primary endpints including a 15.2 ml mean increase (p<0.0001) in RV strke vlume (RVSV) and a 37% reductin (p<0.0001) in PVR frm baseline at Week 26. RVSV was determined by pulmnary artery flw MRI and PVR was measured by right heart catheterizatin. A full evaluatin, with fcus n RV, was als perfrmed using MRI. "Measurement f RV functin in patients with PAH is very helpful in mnitring respnse t treatment," said Richard N. Channick, MD, Prfessr f Medicine and Directr, Acute and Chrnic Thrmbemblic Disease Prgram at UCLA Medical Center. "The REPAIR study shws us that RV functin, as determined by MRI, is a relevant endpint in studying treatment efficacy in PAH." Pulmnary arterial hypertensin is a prgressive disease in which bld vessels in the lungs becme restricted. This frces the right heart t wrk harder t pump bld t the lungs, and RV functin is impaired. The results frm the REPAIR interim analysis suggest that treatment with OPSUMIT is assciated with significantly imprved RV functin as determined by MRI in patients with PAH. In the REPAIR study, the safety prfile f OPSUMIT was cnsistent with previus clinical trial data.these results add t the grwing bdy f research int understanding OPSUMIT in PAH.
"We are very pleased with these interim results frm the REPAIR study and we will wrk diligently t reprt the full study results in the near future," said Alessandr Maresta, MD, VP and Head f Glbal Medical Affairs at Actelin Pharmaceuticals Ltd. "We are cmmitted t nging research and t advancing therapies fr peple with PAH and are prud t make a difference in patients' lives." *Drs. Rsenkranz and Channick have received research supprt frm Actelin and have served as paid cnsultants t the cmpany. Ntes t the Editr ABOUT PULMONARY ARTERIAL HYPERTENSION (PAH) Pulmnary arterial hypertensin (PAH) is a chrnic, life-threatening disrder characterized by abnrmally high bld pressure in the arteries between the heart and lungs f an affected individual. The symptms f PAH are nn-specific and can range frm mild breathlessness and fatigue during nrmal daily activity t symptms f right heart failure and severe restrictins n exercise capacity and ultimately reduced life expectancy. PAH is ne grup within the classificatin f pulmnary hypertensin (PH). This grup includes idipathic PAH, heritable PAH and PAH caused by factrs which include cnnective tissue disease, HIV infectin and cngenital heart disease. The last decade has seen significant advances in the understanding f the pathphysilgy f PAH, which has been paralleled with develpments f treatment guidelines and new therapies. Drugs targeting the three pathways that have been established in the pathgenesis f PAH are endthelin receptr antagnists (ERAs), prstacyclin analgs and phsphdiesterase-5 inhibitrs. PAH treatments have transfrmed the prgnsis fr PAH patients frm symptmatic imprvements in exercise tlerance 10 years ag t delayed disease prgressin tday. Imprved disease awareness and evidence-based guidelines develped frm randmized cntrlled clinical trial data have highlighted the need fr early interventin, gal-riented treatment and cmbinatin therapy. ABOUT THE REPAIR STUDY The Right ventricular Remdeling in Pulmnary ArterIal hypertensin (REPAIR) study is a 52-week, pen-label, multicenter study evaluating the effect f OPSUMIT n right ventricular (RV) remdeling and functin as determined by cardiac MRI and right heart catheterizatin. REPAIR is the first multicenter study in PAH t use a primary endpint measured by MRI enabling clinicians t further understand the direct effects f OPSUMIT n RV remdeling and functin in patients with PAH. In the REPAIR study, OPSUMIT was initiated as mntherapy r sequential cmbinatin therapy with a phsphdiesterase-type 5 (PDE-5) inhibitr r as initial cmbinatin therapy with a PDE-5 inhibitr. The tw primary endpints were (1) change in RVSV frm baseline t Week 26, determined by pulmnary artery flw MRI, and (2) change in PVR frm baseline t Week 26 measured by right heart catheterizatin. In the pre-specified interim analysis including the first 42 patients enrlled, RVSV was significantly increased (mean change 15.2 ml, 96% CI [9.3; 21.0], p<0.0001) and PVR was significantly decreased (37%, 99% CI [26; 46], p<0.0001) at Week 26. The study was declared psitive and enrllment was stpped. All enrlled patients remain in the study up t their 52-week assessments, and a supprtive final analysis will be presented when the results becme available. The REPAIR study shwed that treatment with OPSUMIT was assciated with significant imprvement in RV functin in patients with PAH. What is OPSUMIT (macitentan)?
