入选标准
- •1. Children aged >=6 to <18 years.
- •2. Diagnosed with PAH :
- •- Idiopathic (IPAH)
- •- Hereditable (HPAH)
- •- PAH associated with (APAH)
- •o Connective tissue disease
- •o Congenital heart disease with shunt closure more than 6 months ago (no open shunts, confirmed by RHC no less than 4 months after surgery)
- •3. Diagnosis of PAH confirmed by right heart catheterization (RHC) at any time prior to enrolment (for patients with closed shunts - RHC no less than 4 months after surgery)
- •4. Pulmonary arterial hypertension confirmed by a RHC at any time prior to start of study, with mean pulmonary artery pressure (PAPmean) >=25 mmHg at rest, pulmonary capillary wedge pressure (PCWP) or left ventricular end-diastolic pressure (LVEDP) <=15 mmHg, and pulmonary vascular resistance (PVR) >240 dyn.sec.cm-5 (i.e., >=3.0 wood units.m2)
- •5. Patients must be treated with standard of care comprising background therapy and stable
- •dose of bosentan (at least 12 weeks with stable doses).
- •Two groups of patients will be included:
- •o Prevalent: Patients currently on monotherapy with bosentan who need additional treatment (discretion of the investigator)
- •o Incident: Treatment naïve patients initiated on bosentan then riociguat added once bosentan dose is stable for at least 12 weeks.
- •6. WHO functional class I, II and III
- •7. Adolescent females of childbearing potential can only be included in the study if a pregnancy test is negative. Adolescent females of childbearing potential must agree to use adequate contraception when sexually active. Adequate contraception is defined as any
- •combination of at least 2 effective methods of birth control, of which at least one is a physical barrier (e.g. condoms with hormonal contraception or implants or combined oral contraceptives, certain intrauterine devices). Adequate contraception is required from the signing of the informed consent form up until 6 weeks after the last study drug administration.
- •8. Young men must agree to use adequate contraception when sexually active.
- •9. Written inform consent provided and if applicable child assent provided
- •Are the trial subjects under 18? yes
- •Number of subjects for this age range: 20
- •F.1.2 Adults (18-64 years) no
- •F.1.2.1 Number of subjects for this age range
- •F.1.3 Elderly (>=65 years) no
- •F.1.3.1 Number of subjects for this age range
排除标准
- •1. Concomitant use of the following medications: phosphodiesterase (PDE) 5 Inhibitors (such as sildenafil, tadalafil, vardenafil) and non-specific PDE Inhibitors (theophylline, dipyridamole) in any form or pretreatment are not allowed.
- •Concomitant use of nitrates or NO donors are allowed up to two weeks before Visit 1.
- •2. Active state of hemoptysis or pulmonary hemorrhage, including those events managed by bronchial artery embolization or any history of bronchial artery embolization or massive hemoptysis within 3 months prior to screening
- •3. Systolic blood pressure (SBP) more than 5 mmHg lower than the age-, sex- and height-adapted level of the 50th SBP percentile (NHBPEP, 2004)
- •4. History of left-sided heart disease, including valvular disease or heart failure
- •5. Pulmonary hypertension related to conditions other than specified in the inclusion criteria
- •6. WHO functional class IV
- •7. Pulmonary veno-occlusive disease
- •8. Screening aspartate transaminase (AST) and/ or alanine transaminase (ALT) more than 3 times the upper limit of normal (ULN)
- •9. Non-stable disease status, e.g. , signs and symptoms of decompensated right heart failure
- •10. Severe bronchial asthma
- •11. Severe restrictive lung disease
- •12. Severe congenital abnormalities of the lung, thorax, and diaphragm
- •13. Clinically relevant hepatic dysfunction (especially Child Pugh C)
- •14. Renal insufficiency (estimated glomerular filtration rate <30 mL/min/1.73m2 e.g. calculated based on Schwartz formula)
- •15. Subject with hypersensitivity to the investigational drug or any of the excipients
- •16. Active smoking of tobacco of any type or quantity
- •17. Subjects with known HIV infection (evaluated by medical history)
- •18. Previous assignment to treatment during this study
- •19. Previous (within 30 days) or concomitant participation in another clinical study with investigational medicinal product(s)
- •20. Any condition that, according to treating physician, might jeopardize subject's participation and compliance with procedures indicated in this protocol.
