Research Sponsored by United Therapeutics
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Subjects on pirfenidone or nintedanib must be on a stable and optimized dose for ≥30 days prior to Baseline. Concomitant use of both pirfenidone and nintedanib is not permitted.
Subject is ≥40 years of age, inclusive, at the time of signing informed consent.
Must not have
The subject has shown intolerance or significant lack of efficacy to a prostacyclin or prostacyclin analogue that resulted in discontinuation or inability to effectively titrate that therapy.
Use of any of the following medications: azathioprine (AZA), cyclosporine, mycophenolate mofetil, tacrolimus, oral corticosteroids (OCS) >20 mg/day or the combination of OCS+AZA+N-acetylcysteine within 30 days prior to Baseline; cyclophosphamide within 60 days prior to Baseline; or rituximab within 6 months prior to Baseline.

Summary

This trial will study the safety and effectiveness of inhaled treprostinil in people with a lung disease called idiopathic pulmonary fibrosis.

Who is the study for?
Adults over 40 with Idiopathic Pulmonary Fibrosis (IPF) confirmed by HRCT, having an FVC ≥45% predicted. They must not be pregnant or breastfeeding and agree to use contraception. Participants can't have severe obstructive airway disease, recent heart attacks, uncontrolled cardiac disease, or have used certain IPF treatments recently.
What is being tested?
The trial is testing inhaled treprostinil delivered via a nebulizer against a placebo to see if it improves lung function measured by forced vital capacity (FVC) after one year of treatment in patients with IPF.
What are the potential side effects?
While the side effects for this specific inhalation form are not detailed here, treprostinil can generally cause coughing, headaches, dizziness, nausea, flushing and jaw pain. The severity of these side effects varies from person to person.
