6-minute-walk Distance (6MWD)
Study day 2 or study day 3

The 6-minute walk test was performed 20-40 minutes after treatment. This was a non-encouraged test (the person conducting the test did not encourage the patient to walk farther or faster) that measured the distance covered over a 6-minute walk. It was conducted by a trained member of the site staff who was listed on the site's delegation of authority sheet. For patients who had never performed a 6-minute walk test previously, a training test was requested before the qualifying tests for randomization.

Frequently asked questions about Iloprost

What is Iloprost?

Iloprost is a small molecule drug developed by Johnson & Johnson (ticker JNJ) for rare disease indications, specifically pulmonary arterial hypertension and pulmonary fibrosis. It is administered as an inhalation solution and has been studied in Phase 3 clinical trials. Iloprost is also known as Iloprost Inhalation Solution (Ventavis).

What is Iloprost used for in pulmonary arterial hypertension?

Iloprost is used for the treatment of pulmonary arterial hypertension (PAH). It is also being studied in pulmonary fibrosis. Clinical trials have evaluated its safety and efficacy in adults with PAH, including a Phase 3 trial and a Phase 2 add-on therapy trial with bosentan.

What does Iloprost target?

Iloprost targets PTGIR, the prostacyclin receptor. It acts as an agonist at this receptor, which is a G-protein coupled receptor. This mechanism leads to vasodilation and inhibition of platelet aggregation, which is relevant in conditions like pulmonary arterial hypertension.

Who makes Iloprost?

Iloprost is developed by Johnson & Johnson, which trades under the ticker symbol JNJ. Johnson & Johnson is a multinational pharmaceutical and medical devices company. The drug is part of their portfolio for rare diseases, specifically for pulmonary arterial hypertension.

What phase is Iloprost in?

Iloprost is in Phase 3 clinical development. It has completed three Phase 3 trials and one Phase 2 trial. The Phase 3 trials include the Iloprost Power 15 study and its safety extension, both in pulmonary arterial hypertension. The drug is investigational and not approved.

What clinical trials is Iloprost in?

Iloprost has been studied in several clinical trials, including NCT00709956 (Phase 3, Iloprost Power 15 in PAH), NCT00709098 (Phase 3 safety extension), NCT00109681 (Phase 2 in pulmonary fibrosis and pulmonary hypertension), and NCT00086463 (Phase 2 add-on therapy with bosentan in PAH). All trials are completed.
