Ventavis (iloprost), an inhaled formulation of iloprost, is a synthetic compound structurally similar to prostacyclin (PGI2).
In the US, Ventavis is indicated for the treatment of PAH (WHO Group 1) to improve a composite endpoint consisting of exercise tolerance, symptoms (NYHA Class), and lack of deterioration.
Studies establishing effectiveness included predominately patients with NYHA Functional Class III-IV symptoms and etiologies of idiopathic or heritable PAH (65%) or PAH associated with connective tissue diseases (23%).
Actelion has marketed Ventavis in the US since 2007. Bayer Healthcare markets Ventavis elsewhere.
In a controlled clinical trial, Ventavis improved a composite endpoint consisting of exercise tolerance, symptoms (NYHA Class), and the absence of clinical deterioration.
For patients with PAH (WHO Group 1) with NHYA Class III or IV symptoms, Ventavis has been shown to:
Most common (>3% placebo adjusted) adverse reactions are vasodilation (flushing), cough increased, headache, trismus, insomnia, nausea, hypotension, vomiting, alkaline phosphatase increased, flu syndrome, back pain, tongue pain, palpitations, syncope, GGT increased, muscle cramps, hemoptysis, and pneumonia.
In December 2006, data from the Phase II/III clinical trial STEP, evaluating the use of Ventavis (iloprost) inhalation solution therapy in patients with PAH already undergoing treatment with bosentan were published. The analysis of this study showed that the combination of Ventavis added to bosentan therapy was well tolerated, and was consistent with the safety profile observed in patients receiving only iloprost.
