- W2951316579 abstract "Background Pulmonary arterial hypertension (PAH) is a frequent complication in systemic sclerosis (SSc) and a major cause of death despite the available treatments (1). Until the availability of the oral prostacyclin receptor agonist selexipag in 2016, parenteral medication targeting the prostacyclin pathway was often not feasible for patients with SSc -PAH due to practical barriers. Selexipag added to background therapy improves prognosis of PAH in the published pivotal trial (2). However, to date information on results of SSc-PAH patients treated with any combination of targeted therapies including selexipag in daily clinical practice are lacking. Objectives Evaluation of the efficacy and safety of selexipag in SSc-PAH patients in a real life case series. Methods All patients with SSc associated PAH (WHO group 1) diagnosed by right heart catheterization who started with selexipag between 09-2016 and 06-2018 from two PAH expert centres were included. Data on demographics, concurrent medication, functional class, 6 minute walking distance and NT-pro-BNP level were recorded at baseline and during follow-up. Every 12 weeks we recorded the opinion of the treating expert team, resulting in a conclusion “improvement”, “stabilization” or “deterioration”. Additionally treatment effect was assessed according to the abbreviated risk assessment described by Boucly (3). Side effects and adverse events were registered and evaluated. Results We included 13 SSc-PAH patients, all classified as limited cutaneous SSc. Ten patients were female. Median age was 68 years (IQR 58-75), median SSc disease duration 7.4 years (IQR 4.7-13.5) and median PAH duration 4 years (IQR 2.5-7.5). All patients were on double background therapy. At baseline 1 patient had two low risk criteria, 1 patient had one low risk criterion, the other patients had no low risk criteria. Two patients discontinued selexipag within 4 weeks due to side effects. The eleven patients reaching maintenance dosage had a median follow up of 48 weeks (IQR 24-72). At the end of follow up, 2/11 patients improved, 4/11 stabilized, and 5/11 deteriorated as evaluated by their expert team. Two of these deteriorated patients died due to right ventricular failure and gastro-intestinal bleeding respectively. Of the patients deteriorating, 3 initially stabilized for a period of 24 to 60 weeks. None of the patients achieved 3 low risk criteria, three patients achieved 1 low risk criterion. No unknown side effects were reported. Conclusion Adding selexipag to double background therapy in a high risk cohort stabilized symptoms in the majority of these patients with an acceptable safety profile. Sustained improvement of PAH symptoms is reached in only a minority of our SSc-PAH patients. Further research examining multiple target therapy, including selexipag, in patients with early SSc-associated PAH is warranted. References [1] Lefevre G, et al.
