Inclusion Criteria:<br><br> 1. Subject gives voluntary informed consent to participate in the study.<br><br> 2. Subject is =40 years of age, inclusive, at the time of signing informed consent.<br><br> 3. The subject has a diagnosis of IPF based on the 2018 ATS/ERS/JRS/ALAT Clinical<br> Practice Guideline (Raghu 2018) and confirmed by central review of high-resolution<br> computed tomography (HRCT) (performed within the previous 12 months), and if<br> available, surgical lung biopsy.<br><br> 4. FVC =45% predicted at Screening.<br><br> 5. Subjects on pirfenidone or nintedanib must be on a stable and optimized dose for =30<br> days prior to Baseline. Concomitant use of both pirfenidone and nintedanib is not<br> permitted.<br><br> 6. Women of childbearing potential must be non-pregnant (as confirmed by a urine<br> pregnancy test at Screening and Baseline) and non-lactating, and will abstain from<br> intercourse (when it is in line with their preferred and usual lifestyle) or use 2<br> medically acceptable, highly effective forms of contraception for the duration of<br> the study, and at least 30 days after discontinuing study drug.<br><br> 7. Males with a partner of childbearing potential must use a condom for the duration of<br> treatment and for at least 48 hours after discontinuing study drug.<br><br> 8. In the opinion of the Investigator, the subject is able to communicate effectively<br> with study personnel, and is considered reliable, willing, and likely to be<br> cooperative with protocol requirements, including attending all study visits.<br><br>Exclusion Criteria:<br><br> 1. Subject is pregnant or lactating.<br><br> 2. Subject has primary obstructive airway physiology: FEV1/FVC <0.70 at Screening.<br><br> 3. The subject has shown intolerance or significant lack of efficacy to a prostacyclin<br> or prostacyclin analogue that resulted in discontinuation or inability to<br> effectively titrate that therapy.<br><br> 4. The subject has received any PAH-approved therapy, including prostacyclin therapy<br> (epoprostenol, treprostinil, iloprost, or beraprost; except for acute vasoreactivity<br> testing), IP receptor agonists (selexipag), endothelin receptor antagonists,<br> phosphodiesterase type 5 inhibitors (PDE5-Is), or soluble guanylate cyclase<br> stimulators within 60 days prior to Baseline. As needed use of a PDE5-I for erectile<br> dysfunction is permitted, provided no doses are taken within 48 hours of any<br> study-related efficacy assessments.<br><br> 5. Use of any of the following medications: azathioprine (AZA), cyclosporine,<br> mycophenolate mofetil, tacrolimus, oral corticosteroids (OCS) >20 mg/day or the<br> combination of OCS+AZA+N-acetylcysteine within 30 days prior to Baseline;<br> cyclophosphamide within 60 days prior to Baseline; or rituximab within 6 months<br> prior to Baseline.<br><br> 6. The subject is receiving >10 L/min of oxygen supplementation by any mode of delivery<br> at rest at Baseline.<br><br> 7. Exacerbation of IPF or active pulmonary or upper respiratory infection within 30<br> days prior to Baseline. Subjects must have completed any antibiotic or steroid<br> regimens for treatment of the infection or acute exacerbation more than 30 days<br> prior to Baseline to be eligible. If hospitalized for an acute exacerbation of IPF<br> or a pulmonary or upper respiratory infection, subjects must have been discharged<br> more than 90 days prior to Baseline to be eligible.<br><br> 8. Uncontrolled cardiac disease, defined as myocardial infarction within 6 months prior<br> to Baseline or unstable angina within 30 days prior to Baseline.<br><br> 9. In the opinion of the Investigator, the subject has any condition that would<br> interfere with the interpretation of study assessments or would impair study<br> participation or cooperation.<br><br> 10. Use of any other investigational drug/device or participation in any investigational<br> study in which the subject received a medical intervention (ie, procedure, device,<br> medication/supplement) within 30 days prior to Screening. Subjects participating in<br> non-interventional, observational, or registry studies are eligible.<br><br> 11. Life expectancy <6 months due to IPF or a concomitant illness.<br><br> 12. Acute pulmonary embolism within 90 days prior to Baseline.
