Brief summary
The primary objective of this study is to evaluate the safety and tolerability of the long-term use of TPIP in participants with PH-ILD from Study INS1009-211 (NCT05176951) and other lead-in studies of TPIP in participants with PH-ILD.

Inclusion criteria
* Participants who completed the end of treatment visit in Study INS1009-211 (NCT05176951). 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 INS1009-211, or any other lead-in PH-ILD TPIP study. * Capable of giving signed informed consent that includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.
Exclusion criteria
* Participants who experienced any hypersensitivity or adverse drug reaction or were withdrawn early/discontinued in a previous PH-ILD TPIP study, which in the opinion of the Investigator, could indicate that continued treatment with TPIP may present an unreasonable risk for the participant. * Initiation of parenteral administration of prostacyclin analogues (eg, TRE, epoprostenol) since the completion of Study INS1009-211 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. Pregnant or breastfeeding. Male and female participants must use contraceptives that are consistent with local regulations regarding the methods of contraception for those participating in clinical studies. Female participants of childbearing potential must have a negative urine pregnancy test result at trial entry before the first dose of study drug. \- Any medical or psychological condition, including relevant laboratory abnormalities at screening that, in the opinion of the Investigator, suggest a new and/or insufficiently understood disease that may present an unreasonable risk to the study participant as a result of participation in the study.

| Annualized Rate of Clinical Worsening Events Based on Percentage of Participants With Clinical Worsening Events | Up to Month 24 | Clinical worsening events are defined as one of the following: Hospitalization due to a cardiopulmonary indication; Lung transplantation; Death from any cause; Decrease in 6MWD ≥ 15% from baseline; Directly related to disease under study, at 2 consecutive visits at least 24 hours apart; Need for additional pulmonary hypertension (PH) therapy.
