Disease Classification

PAH disease severity

The WHO Group 1 Classification of Pulmonary Hypertension (Fifth World Symposium on Pulmonary Hypertension version) helps categorize pulmonary arterial hypertension (PAH) by type and the New York Heart Association (NYHA) Functional Assessment measures symptoms severity associated with PAH. Both classification systems are below.

VENTAVIS® (iloprost) Inhalation Solution is indicated for the treatment of pulmonary arterial hypertension (PAH) (WHO Group 1) to improve a composite endpoint consisting of exercise tolerance, symptoms (NYHA Class), and lack of deterioration. Studies establishing effectiveness included predominantly patients with NYHA Functional Class III-IV symptoms and etiologies of idiopathic or heritable PAH (65%) or PAH associated with connective tissue disease (23%).

1.4.3 Portal hypertension

1.4.4 Congenital heart diseases

1.4.5 Schistosomiasis

1′ Pulmonary veno-occlusive disease and/or pulmonary capillary hemangiomatosis

New York Heart Association (NYHA) Functional Classification24

NYHA Functional Assessment  
Class I: No symptoms with ordinary physical activity.  
Class II: Symptoms with ordinary activity. Slight limitation of activity.  
Class III: Symptoms with less than ordinary activity. Marked limitation of activity.  
Class IV: Symptoms with any activity or even at rest.  

The effectiveness of VENTAVIS was established predominantly in patients with NYHA Functional Class III-IV symptoms.

INDICATION

VENTAVIS® (iloprost) Inhalation Solution is indicated for the treatment of pulmonary arterial hypertension (PAH) (WHO Group 1) to improve a composite endpoint consisting of exercise tolerance, symptoms (NYHA Class), and lack of deterioration. Studies establishing effectiveness included predominantly patients with NYHA Functional Class III-IV symptoms and etiologies of idiopathic or heritable PAH (65%) or PAH associated with connective tissue disease (23%).

IMPORTANT SAFETY INFORMATION

WARNINGS AND PRECAUTIONS

Risk of Syncope

  • Vital signs should be monitored while initiating VENTAVIS. Hypotension leading to syncope has been observed; VENTAVIS should therefore not be initiated in patients with systolic blood pressure less than 85 mmHg.

Pulmonary Venous Hypertension

  • Stop VENTAVIS immediately if signs of pulmonary edema occur; this may be a sign of pulmonary venous hypertension.

Bronchospasm

  • VENTAVIS inhalation may cause bronchospasm and patients with a history of hyperreactive airway disease may be more sensitive.

ADVERSE REACTIONS

Serious Adverse Events

  • Serious adverse events reported include congestive heart failure, chest pain, supraventricular tachycardia, dyspnea, peripheral edema, and kidney failure.

Adverse Events

  • Adverse events reported in a Phase 3 clinical trial occurring with a ≥3% difference between VENTAVIS patients and placebo patients were vasodilation (flushing) (27% vs 9%), increased cough (39% vs 26%), headache (30% vs 20%), trismus (12% vs 3%), insomnia (8% vs 2%), nausea (13% vs 8%), hypotension (11% vs 6%), vomiting (7% vs 2%), alkaline phosphatase increased (6% vs 1%), flu syndrome (14% vs 10%), back pain (7% vs 3%), tongue pain (4% vs 0%), palpitations (7% vs 4%), syncope (8% vs 5%), GGT increased (6% vs 3%), muscle cramps (6% vs 3%), hemoptysis (5% vs 2%), and pneumonia (4% vs 1%).

DRUG INTERACTIONS

Antihypertensives and Vasodilators

  • VENTAVIS has the potential to increase the hypotensive effect of vasodilators and antihypertensive agents.

Anticoagulants and Platelet Inhibitors

  • VENTAVIS also has the potential to increase risk of bleeding, particularly in patients maintained on anticoagulants or platelet inhibitors.
