BACKGROUND: Registry data suggest that disease progression in pulmonary arterial hypertension (PAH) is indicative of poor prognosis. However, the prognostic relevance of PAH-related morbidity has not been formally evaluated in randomized controlled trials. OBJECTIVES: The purpose of these analyses was to assess the impact of morbidity events on the risk of subsequent mortality using the landmark method and data from the SERAPHIN and GRIPHON studies. METHODS: For each study, the risk of all-cause death up to the end of the study was assessed from the landmark time point (months 3, 6, and 12) according to whether a patient had experienced a primary endpoint morbidity event before the landmark...

Despite recent advances in pulmonary arterial hypertension (PAH) treatment, this condition is still characterized by an extremely poor prognosis. In this review, we discuss the use of newly-approved drugs for PAH treatment with already known mechanisms of action (macitentan), innovative targets (riociguat and selexipag), and novel therapeutic approaches with initial up-front combination therapy. Secondly, we describe new potential signalling pathways and investigational drugs with promising role in the treatment of PAH...

Idiopathic pulmonary fibrosis (IPF) is a severe and often fatal disease with a median survival of 2 - 4 years after diagnosis. Since the publication of the German IPF guideline in 2013 new treatment trials have been published, necessitating an update of the pharmacological therapy of IPF. Different from the previous guideline, the GRADE system was discarded and replaced by the Oxford evidence classification system which allows a more differentiated judgement. The following pharmacological therapies were rated not suitable for the treatment of IPF patients (recommendation A; evidence 1-b): triple therapy with prednisolone, azathioprine and acetyl-cysteine; imatinib; ambrisentan; bosentan; macitentan...

Several endothelin receptor antagonists (ERAs) that were developed for the treatment of pulmonary arterial hypertension (PAH), including bosentan and sitaxentan, have been linked to clinically significant hepatocellular injury, as well as liver failure. We describe the first case of fulminant hepatitis to be reported in association with the ERA macitentan. This case was recently identified within the United States Food and Drug Administration Adverse Event Reporting System (FAERS) and and describes liver transplantation occuring 13 months following macitentan initiation in a young patient (23-years old) with idiopathic PAH New York Heart Association (NYHA) functional class III...

REVIEW
Pavel Jansa, Tomás Pulido
SERAPHIN was a double-blind, placebo-controlled, event-driven phase III trial that evaluated the effects of long-term treatment with macitentan, an oral endothelin receptor antagonist, in patients with pulmonary arterial hypertension (PAH). The majority of patients were receiving PAH therapy at enrollment, providing the opportunity to evaluate the efficacy and safety of macitentan in combination with other PAH therapies (predominantly phosphodiesterase type 5 inhibitors [PDE-5i]). In patients receiving background therapy, macitentan reduced the risk of morbidity/mortality by 38% compared with placebo (hazard ratio [HR] 0...

The effectiveness and safety of macitentan, a dual endothelin-receptor antagonist (ERA) approved for the treatment of pulmonary arterial hypertension (PAH), were shown in an extensive clinical trial oriented towards morbidity and mortality events. Our aim was to describe a single centre's experience of the utilization of macitentan in patients with PAH in clinical practice settings. Thirteen patients with different aetiologies and previous PAH treatments were studied. After 12 months of macitentan treatment, 11 patients improved their functional class (FC), all patients improved their 6-minute walk distance (6MWD) test, and 10 patients lowered their NT-proBNP plasma levels...

The crosstalk between chronic lymphocytic leukemia (CLL) cells and tumor microenvironment is essential for leukemic clone maintenance, supporting CLL cells survival, proliferation and protection from drug-induced apoptosis. Over the past years, the role of several soluble factors involved in these processes has been studied. CLL cells express higher levels of endothelin 1 (ET-1) and ETA receptor as compared to normal B cells. Upon ET-1 stimulation, CLL cells improve their survival and proliferation and reduce their sensitivity to the phosphoinositide-3-kinase δ inhibitor idelalisib and to fludarabine...

The paper considers a clinical example of current therapy for idiopathic pulmonary arterial hypertension in a female patient with its clinical deterioration. It shows the tactics of switching from one drug (bosentan) to others (macitentan) within in the same pathogenetic therapy group (endothelin receptor antagonists). The latest pulmonary hypertension classification (Nice, 2013) is presented. The current strategies of pathogenetic therapy for pulmonary hypertension are discussed.

BACKGROUND: Macitentan is beneficial for long-term treatment of pulmonary arterial hypertension. The microvasculopathy of chronic thromboembolic pulmonary hypertension (CTEPH) and pulmonary arterial hypertension are similar. METHODS: The phase 2, double-blind, randomised, placebo-controlled MERIT-1 trial assessed macitentan in 80 patients with CTEPH adjudicated as inoperable. Patients identified as WHO functional class II-IV with a pulmonary vascular resistance (PVR) of at least 400 dyn·s/cm5 and a walk distance of 150-450 m in 6 min were randomly assigned (1:1), via an interactive voice/web response system, to receive oral macitentan (10 mg once a day) or placebo...

A plethora of properties are typically studied during a medicinal chemistry program and many of these parameters may shape the cascade of compound selection. Given the task to discover a molecule with a profile superior to that of the dual endothelin receptor antagonist bosentan, we tailored our compound profiling cascade to the specific properties that were not optimal in bosentan, namely in vivo efficacy and safety. Contrary to conventional thinking, we therefore focused on corresponding in vivo experiments...

The limited clinical response to conventional chemotherapeutics observed in colorectal cancer (CRC) may be related to the connections between the hyperactivated β-catenin signaling and other pathways in CRC stem-like cells (CRC-SC). Here, we show the mechanistic link between the endothelin-1 (ET-1)/ET-1 receptor (ET-1R) signaling and β-catenin pathway through the specific interaction with the signal transducer β-arrestin1 (β-arr1), which initiates signaling cascades as part of the signaling complex. Using a panel of patient-derived CRC-SC, we show that these cells secrete ET-1 and express ETAR and β-arr1, and that the activation of ETAR/β-arr1 axis promotes the cross-talk with β-catenin signaling to sustain stemness, epithelial-to-mesenchymal transition (EMT) phenotype and response to chemotherapy...

In patients treated with macitentan (Opsumit®, Actelion Pharmaceuticals Ltd., Basel, Switzerland) for pulmonary arterial hypertension (PAH), prevention and/or effective management of treatment-related adverse events may improve adherence. However, management of these adverse events can be challenging and the base of evidence and clinical experience for macitentan is limited. In the absence of evidence, consensus recommendations from physicians experienced in using macitentan to treat PAH may benefit patients and physicians who are using macitentan...

Combination treatment with endothelin receptor antagonists (ERA) and phosphodiesterase 5 inhibitors (PDE5I) improved efficacy of pulmonary arterial hypertension (PAH) therapy. However, drug-drug interactions, variable exposure, non-adherence can influence plasma levels. For these reasons, drug quantification may be advantageous particularly in patients with poor treatment responses. We developed, validated, and applied an assay for the simultaneous quantification of ambrisentan, bosentan, macitentan, sildenafil, and tadalafil as well as their main (and partly active) metabolites in human plasma...
