JenksDepartment of Pediatrics, Division of Pediatric Critical Care, University of Mississippi Medical Center, Jackson, MS, USACategory: Clinical ScienceSelected Areas: Pediatrics, Therapeutic StrategiesBackground: Pulmonary hypertension (PH) is a rare and potentially fatal disease in children if left untreated. Emerging therapies, including bosentan, a dual endothelin receptor antagonist (ERA), have shown significant benefits in the adult PH population; however, few studies have assessed the efficacy and safety of ERAs in infants and young children.Methods: Our study was a single-center retrospective analysis of patients <2 years of age with a confirmed diagnosis of PH and started on bosentan therapy between 2017 and 2020. Twelve cases met eligibility criteria. Demographic (Table 1), laboratory, echocardiographic, and cardiac catheterization data were analyzed (Tables 2–4).Results: With treatment, there was a statistically significant decrease in mean right ventricular systolic pressure estimated by the tricuspid regurgitation jet (79 ± 23 mm Hg reduced to 52 ± 25 mm Hg; P value <0.001) and pro-brain natriuretic peptide levels (21 071 reduced to 2037; P < 0.001). Additionally, improvement and eventual normalization of right ventricular function and septal geometry was seen within the first 4 months of therapy (Figure). Patients who underwent cardiac catheterization after therapy initiation (n = 4) demonstrated hemodynamic improvements; however, only the decrease in diastolic pulmonary pressure was statistically significant (P value = 0.018). No significant difference in hemoglobin, platelet count, or liver function tests was observed between groups.Conclusions: In conclusion, these data suggest that bosentan may be an effective and relatively safe treatment option for children <2 years of age with PH. Further long-term randomized control studies are necessary to validate the potential clinical benefit of using this drug therapy in young children.Essam IbrahimJanssen Inc., Toronto, Ontario, CanadaAssem Al-AkabawiJanssen Inc., Toronto, Ontario, CanadaMoses DawoduJanssen Inc., Toronto, Ontario, CanadaJuejing LingIQVIA Solutions Canada Inc., Kirkland, Quebec, CanadaIrene WangIQVIA Solutions Canada Inc., Kirkland, Quebec, CanadaBrad MillsonIQVIA Solutions Canada Inc., Kirkland, Quebec, CanadaCategory: Clinical ScienceSelected Areas: Databases and RegistriesBackground: The current standard of care for pulmonary arterial hypertension (PAH) is combination therapy, which imposes pill burden on PAH patients who live with multiple comorbidities. This study aims to understand the concomitant medication use in treatment journey of Canadian PAH patients.Methods: Patients initiating PAH therapy (index) from September 1, 2016, to August 31, 2019, were selected in the Ontario Drug Benefits (ODB), Régie de l’assurance maladie du Québec (RAMQ), and IQVIA Canadian Private Drug Plan (PDP) databases. Medication prescriptions 5-year prior and 1-year postindex were tracked. Concomitant medication analysis used ODB and PDP; prescriber specialty analysis used PDP database.Results: A total of 1019 patients were included from ODB (N = 481), PDP (N = 422), and RAMQ (N = 116). Tadalafil (61%) and sildenafil (22%) were most prescribed at index. One year prior to index, 75% and 30% of patients with concomitant medications (N = 828) were on 5+ and 10+ concomitant medication classes, respectively. From 5 years prior to the 1-year postindex, the proportion of cardiovascular medications use declined (16% versus 13%), while that of diuretics use increased (10% versus 16%). Compared with the year prior, prescriptions of rescue treatment decreased 1 year postindex (926 versus 763). Here, 72% of patients (N = 300) were prescribed by general practitioner (GP) before index, while prescribers of cardiovascular and respiratory medications shifted from GP to specialist postindex. Among the top 3 prescribers, females had a significant reduction in the number of concomitant medications postindex, while males trended the opposite way.Conclusions: This study shows the complex treatment journey of Canadian PAH patients and highlights the need to reduce pill burden and improve disease management.Essam IbrahimJanssen Inc., Toronto, Ontario, CanadaAssem Al-AkabawiJanssen Inc., Toronto, Ontario, CanadaMoses DawoduJanssen Inc., Toronto, Ontario, CanadaJuejing LingIQVIA Solutions Canada Inc., Kirkland, Quebec, CanadaJillian MurrayIQVIA Solutions Canada Inc., Kirkland, Quebec, CanadaBrad MillsonIQVIA Solutions Canada Inc., Kirkland, Quebec, CanadaCategory: Clinical ScienceSelected Areas: Databases and RegistriesBackground: Treatment guidelines for pulmonary arterial hypertension (PAH) recommend combination therapy in most patients. This study evaluated retention of PAH drugs and time-to-initiation of combination drug therapy with macitentan and selexipag in Canada.Methods: Patients claiming PAH drugs from January 2017 to March 2021 were identified in the Ontario Drug Benefits (ODB), Régie de l’assurance maladie du Québec (RAMQ), and IQVIA Canadian Private Drug Plan (PDP) databases. Drug retention was calculated for patients submitting claims 12 months following treatment index (March 2019 to February 2020 [PDP, ODB]; January to December 2019 [RAMQ]). Treatment was considered first line if patients were treatment naïve with >180 days of claims history. Time-to-initiation of combination therapy was calculated for macitentan+PDE5i and selexipag-containing therapies.Results: Around 2150 patients claimed PAH drugs annually, with averages of 1000 (PDP), 900 (ODB), and 250 (RAMQ). Most patients were female (65%–77%) and aged 45+ years (69%–85%). The 12-month retention was greatest for macitentan in PDP (67%) and RAMQ (88%), and tadalafil (78%) in ODB. Of patients on macitentan or selexipag, approximately 79% and 95% were on combination therapy (2+ drugs) in 2020, respectively. In 2020, 12%–17% of patients were on macitentan combination therapy (3+ drugs), and 43%–69% were on selexipag combination therapy (3+ drugs). In 2020, mean time-to-initiation was 4–5 months for macitentan+PDE5i and 17–23 months for selexipag-containing therapies (Table).Conclusions: Real-world data from Canada shows that most PAH patients on macitentan or selexipag are on combination therapies. Time-to-initiation was 4–5 months for macitentan+PDE5i, and 17–23 months for selexipag-containing combination therapies. This study shows the complex treatment journey of Canadian PAH patients and highlights the need to reduce pill burden and improve disease management.Roxana SulicaPulmonary Critical Care and Sleep Division, NYU Grossman School of Medicine, NYU Langone Health, New York, NY, USAStacy MandrasAdventHealth Transplant Institute, Orlando, FL, USAChad MillerPiedmont Physicians, Pulmonary Hypertension/Pulmonary Critical Care Medicine, Piedmont Healthcare, Austell, GA, USAR.

Riociguat was approved for PAH based on the PATENT study, which studied it as monotherapy or in sequential combination with an endothelin receptor antagonist (ERA) or nonparenteral prostanoid. PATENT and REPLACE gave substantial data on riociguat combinations, but there are no US-based registry data on riociguat.Methods: ROAR (NCT04813926; funder: Bayer US, LLC) is a US-based, multicenter, prospective, observational registry of adults with PAH who are riociguat-naïve or who initiated riociguat 90 days previously. Data will be collected at standard-of-care visits (usually every 3–6 months) for 24 months or until 30 days after discontinuing riociguat. Planned enrollment: 500 patients (~50 sites).

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
