Treprostinil Palmitil Inhalation Powder in Pulmonary Arterial Hypertension

What is the Purpose of this Study?

The purpose of this study is to evaluate an experimental drug called treprostinil palmitil inhalation powder (TPIP) for the treatment of pulmonary arterial hypertension (PAH). The study aims to determine the safety, tolerability, and effectiveness of TPIP in PAH patients. Specifically, researchers want to know how safe it is to take TPIP for a long period of time, as well as learn more about how the drug works in the human body and the substances it produces (biomarkers). The study will also measure the amount of TPIP in the body (pharmacokinetics) and examine how the body reacts to the drug. Study procedures also include laboratory blood testing, a 6-minute walk test, and electrocardiogram (ECG).

Eligibility

* Male and female participants who completed end of treatment study visit in Study INS1009-201, INS1009-202, or any other lead-in PAH TPIP study. Participants for whom the OLE study was not available at the time of their completion of the lead-in study are eligible for enrolment within one year of their lead-in end of treatment visit.
* Complete baseline screening assessments to confirm eligibility to participate if more than 30 days have elapsed since the end of the study visit in Study INS1009-201, INS1009-202, or any other lead-in PAH TPIP study.

Inclusion Criteria:

* Male and female participants who completed end of treatment study visit in Study INS1009-201, INS1009-202, or any other lead-in PAH TPIP study. Participants for whom the OLE study was not available at the time of their completion of the lead-in study are eligible for enrolment within one year of their lead-in end of treatment visit.
* Complete baseline screening assessments to confirm eligibility to participate if more than 30 days have elapsed since the end of the study visit in Study INS1009-201, INS1009-202, or any other lead-in PAH TPIP study.

Exclusion Criteria:

* Initiation of parenteral administration of prostacyclin analogues (eg, TRE, epoprostenol) since the completion of studies INS1009-201, INS1009-202 or other TPIP studies. Initiation of inhaled prostacyclin analogues (eg, TRE \[Tyvaso\] or iloprost) and oral prostacyclin analogues (eg, TRE \[Orenitram\]) or receptor agonists (eg, selexipag) are permitted if stopped 24 hours prior to the start of study drug administration.
* Any new ventricular or supraventricular tachyarrhythmia except for paroxysmal atrial fibrillation and any new symptomatic bradycardia.
* New-onset of heart disease including left ventricular ejection fraction (LVEF) ≤40% or clinically significant valvular, constrictive, or symptomatic atherosclerotic heart disease (eg, stable angina, myocardial infarction, etc).
* New evidence of thromboembolic disease as assessed by ventilation/perfusion (VQ) scan, pulmonary angiography, or pulmonary computed tomography (CT) scan.
* Active and current symptomatic coronavirus disease 2019 (COVID-19) or previous severe disease and/or hospitalization due to COVID-19.
* Interval organ transplantation.
* New active liver disease or hepatic dysfunction.
* Interval malignancy with exception of completely treated in situ carcinoma of the cervix and completely treated non-metastatic squamous or basal cell carcinoma of the skin.
* Use of any investigational drug/device or participation in any investigational study within 30 days prior to screening, not including TPIP of the lead-in study.
* Current use of cigarettes (as defined by Centers for Disease Control and Prevention \[CDC\]) or e-cigarettes: An adult who has smoked at least 100 cigarettes in his or her lifetime, who smokes either every day or some days.
* Participants who currently inhale marijuana (recreational or medical).
