• Prior exposure to sotatercept (ACE-011) or luspatercept (ACE-536) or known allergic reaction to either one
• Initiation of a structured exercise program within 90 days prior or planned initiation during the study
• Cerebrovascular accident within 3 months prior to the screening visit
• Acutely decompensated heart failure within 14 days prior to the screening visit, as per investigator assessment
• Received intravenous inotropes (e.g., dobutamine, dopamine, norepinephrine, vasopressin) within 30 days prior to the screening visit

Más betegség

• Diagnosis of the following PAH Group 1 subtypes: human immunodeficiency virus (HIV)-associated PAH, PAH associated with portal hypertension, schistosomiasis-associated PAH and pulmonary veno-occlusive disease
• Uncontrolled systemic hypertension as evidenced by sitting systolic BP > 160 mmHg or sitting diastolic BP > 100 mmHg during screening visit after a period of rest; Baseline systolic BP < 90 mmHg at screening
• History of full pneumonectomy
• Known history of portal hypertension or chronic liver disease, including hepatitis B and/or hepatitis C (with evidence of recent infection and/or active virus replication), defined as mild to severe hepatic impairment (Child-Pugh Class A-C).
• Significant (≥ 2+ regurgitation) mitral regurgitation or aortic regurgitation valvular disease

Laborértékek

• Hemoglobin at screening above gender-specific ULN
• Baseline platelet count < 50,000/mm3 (< 50.0 × 109/L) at screening
• Clinical laboratory liver and kidney function tests outside of normal range
• Cardiac related history: History of restrictive, constrictive, or congestive cardiomyopathy; History of atrial septostomy within 180 days prior to the screening visit; ECG with Fridericia's corrected QT interval (QTcF) > 500 ms during the Screening Period; Personal or family history of long QT syndrome (LQTS) or sudden cardiac death; Left ventricular ejection fraction (LVEF) < 45% on historical ECHO within 12 months prior to the screening visit; Any symptomatic coronary disease events (prior myocardial infarction, percutaneous coronary intervention, coronary artery bypass graft surgery, or cardiac anginal chest pain) within 6 months prior to the screening visit. Note: Anginal pain can be ignored as an exclusion criterion if coronary angiography shows no obstructions
