pulmonary arterial hypertension

Comparative PK PD Study in PAH patients (Fox vs. I-Neb)

Trial purpose

Administration of iloprost aerosol comparing two nebulizers: FOX and I-Neb

Key Participants Requirements

Sex

Both

Age

18 - N/A
  • - Male or female aged ≥ 18 years
    - Current diagnosis of pulmonary hypertension (updated Dana Point Classification 1).
    - Current inhalative therapy with 5 µg iloprost using the
    I-Neb nebulizer
    - WHO functional class III at the time of the patient's commencement of inhalative therapy with iloprost
    - Hemodynamic diagnosis of Pulmonary arterial hypertension(PAH) showing mean pulmonary arterial pressure (mPAP) > 25 mmHg, pulmonary capillary wedge pressure (PCWP) or left ventricular end diastolic pressure (LVEDP) < 15 mmHg and pulmonary vascular resistance (PVR) > 320 dyn•s•cm–5
    - If non-specific types of chronic treatment for PAH are being administered: Stable dosage of these for at least the 4 weeks up to screening
    - If PAH-specific drug treatments (such as endothelin receptor antagonist (ERA) or phosphodiesterase-5 (PDE5) inhibitors) are being administered: Stable dosage of these for at least the 3 months up to screening.
  • -PAH related to any other etiology, especially to pulmonary veno-occlusive disease (PVOD)
    - Clinically relevant obstructive lung disease
    - Evidence of thromboembolic disease (probable pulmonary embolism) within 3 years before screening
    - Cerebrovascular events within 3 months before screening
    - Atrial septostomy within the 6 months before screening
    - Severe arrhythmia, or severe coronary heart disease or unstable angina, or myocardial infarction within 6 months before screening, or congenital or acquired valvular defects with clinically relevant myocardial function disorders unrelated to PAH
    - Systolic blood pressure < 85 mm Hg, or uncontrolled systemic hypertension (systolic BP > 160 mmHg or diastolic BP > 100 mmHg)
    - Hepatic impairment (Child Pugh B, C) or chronic renal insufficiency (creatinine > 2.5 mg/dl) and /or requirement of dialysis
    - Clinically relevant bleedings disorders or conditions with increased risk for hemorrhages (active ulcers, trauma etc.)
    - Addition or dose change of PAH specific drug treatments such as ERA or PDE5 inhibitors within 3 months before screening, or addition or dose change of non-specific treatments for PAH such as calcium channel blockers, nitrates, digitalis, diuretics within 4 weeks before Screening, or any kind of prostanoid other than those mentioned in inclusion criteria within less than 5 half-lives before treatment
