Exercise Data in Idiopathic or Heritable Pulmonary Arterial Hypertension (IPAH/HPAH*) at 12 Weeks
Increased Exercise Capacity1
In two prospective, open-label, randomized trials of 8 and 12 weeks’ duration in patients with IPAH/HPAH* NYHA functional class III or IV (pooled data results), statistically significant improvement was observed in exercise capacity, as measured by the 6-minute walk test in patients receiving continuous intravenous epoprostenol plus conventional therapy (n=52) compared to those receiving conventional therapy alone (n=54).
Adverse events included flushing, jaw pain, headache, hypotension, tachycardia, nausea, vomiting, flu-like symptoms, anxiety/nervousness and diarrhea.
Patients received chronic continuous infusions of epoprostenol sodium plus conventional therapy or conventional therapy alone. Conventional therapy could include anticoagulants, oral vasodilators, supplemental oxygen, digoxin, and/or diuretics.

INDICATION
Veletri is indicated for the treatment of pulmonary arterial hypertension (PAH) (WHO Group 1) to improve exercise capacity. Studies establishing effectiveness included predominantly patients with NYHA Functional Class III-IV symptoms and etiologies of idiopathic or heritable PAH or PAH associated with connective tissue diseases.
IMPORTANT SAFETY INFORMATION
Veletri is contraindicated in patients with congestive heart failure due to severe left ventricular systolic dysfunction, in patients who develop pulmonary edema during dose initiation, and in patients who have known hypersensitivity to the drug or to structurally related compounds.
Veletri should be used only by clinicians experienced in the diagnosis and treatment of pulmonary hypertension after establishing the diagnosis of idiopathic or heritable PAH or PAH/CTD.
Reconstitute Veletri only as directed using Sterile Water for Injection, USP, or Sodium Chloride 0.9% Injection, USP. Do not mix Veletri with any other parenteral medications or solutions prior to or during administration. Do not abruptly lower the dose or withdraw dosing. All dosing initiation and changes should be closely monitored.
The most common and dose-limiting adverse events during dose initiation and escalation were flushing (58%), headache (49%), nausea/vomiting (32%), hypotension (16%), chest pain (11%), and anxiety (11%).
Adverse events occurring in patients with idiopathic or heritable PAH with =10% difference between epoprostenol and conventional therapy alone were chills/fever/sepsis/flu-like symptoms (25% vs 11%), tachycardia (35% vs 24%), flushing (42% vs 2%), diarrhea (37% vs 6%), nausea/vomiting (67% vs 48%), jaw pain (54% vs 0%), myalgia (44% vs 31%), nonspecific musculoskeletal pain (35% vs 15%), anxiety/nervousness/tremor (21% vs 9%), dizziness (83% vs 70%), headache (83% vs 33%), and hypesthesia/hyperesthesia/paresthesia (12% vs 2%).
Adverse events occurring in patients with PAH/CTD with =10% difference between epoprostenol and conventional therapy alone were flushing (23% vs 0%), hypotension (13% vs 0%), anorexia (66% vs 47%), nausea/vomiting (41% vs 16%), diarrhea (50% vs 5%), jaw pain (75% vs 0%), pain/neck pain/arthralgia (84% vs 65%), headache (46% vs 5%), skin ulcer (39% vs 24%), and eczema/rash/urticaria (25% vs 4%).
Additional reductions in blood pressure may occur when Veletri is administered with diuretics, antihypertensive agents, or other vasodilators. There is the potential for Veletri to increase the risk of bleeding when administered with antiplatelet agents or anticoagulants. Patients on digoxin who receive Veletri may show elevations of digoxin concentration, which may be clinically significant in patients prone to digoxin toxicity.
