Inclusion criteria
* Males and females must be ≥ 18 to ≤ 80 years of age at the time of signing the informed consent form (ICF). * Diagnosis of pulmonary hypertension (PH) associated with interstitial lung disease (ILD) (including idiopathic interstitial pneumonia \[IIP\], idiopathic pulmonary fibrosis \[IPF\], connective tissue disease \[CTD\], sarcoidosis). * Male and female participants must use contraceptives that are consistent with local regulations regarding the methods of contraception for those participating in clinical studies. * Male participants: Male participants who are not sterile, with female partners of childbearing potential, must be using effective contraception from Day 1 to at least 90 days after the last dose of study drug. Male participants with women of child bearing potential (WOCBP) partner must use a condom in order to avoid potential exposure to embryo/fetus. \- Female participants: Women must be postmenopausal (defined as no menses for 12 months without an alternative medical cause), surgically sterile, (ie,hysterectomy and/or bilateral salpingo-oophorectomy) or using highly effective contraception methods (ie, methods that alone or in combination achieve \<1% unintended pregnancy rates per year when used consistently and correctly) from Day 1 to at least 90 days after the last dose of study drug. \- Capable of giving signed informed consent that includes compliance with the requirements and restrictions listed in the ICF and in this protocol.
Exclusion criteria
* Primary diagnosis of chronic obstructive pulmonary disease (COPD). * Allergy, or documented hypersensitivity or contraindication to TPIP or treprostinil (TRE) or mannitol (an excipient of the TPIP formulation). * Received or currently treated with riociguat, endothelin receptor antagonists, selexipag, phosphodiesterase 5 (PDE5) inhibitors and/or prostacyclin analogues within 30 days prior to Screening. * Started therapy with pirfenidone or nintedanib \< 90 days prior to Screening, OR, if already receiving either medication, there is a dose change within 30 days of Screening Visit. * Any known ventricular or supraventricular tachyarrhythmia (except for paroxysmal atrial fibrillation), and/or any symptomatic bradycardia. * History 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). * Participation in a cardiopulmonary rehabilitation program within 30 days of the first Screening Visit. Participation in the maintenance program of a cardiopulmonary rehabilitation program is allowed. * Acutely decompensated heart failure within 30 days of Screening Visit. * Active and current symptomatic coronavirus disease 2019 (COVID-19) and/or previous diagnosis of moderate to severe disease, or hospitalization due to COVID-19. * Supplemental oxygen requirement \> 10L/min at rest at Screening. * Exacerbation of underlying lung disease or active pulmonary or upper respiratory infection within 30 days of the first dose of study drug (may be rescreened at appropriate time). * Current or recent (past 30 days) lower respiratory tract infection (may be rescreened at appropriate time). * Any form of congenital heart disease or congenital heart defect (repaired or unrepaired) other than a patent foramen ovale. * History of alcohol or drug abuse within 6 months prior to Screening. * Current use of cigarettes (as defined by Center for Disease Control (CDC)) or e-cigarettes: An adult who has smoked at least 100 cigarettes in his or her lifetime and who currently smokes either every day or some days. * Participants who currently inhale marijuana (recreational or medical). * Acute or chronic impairment (other than dyspnea), limiting the ability to comply with study requirements, in particular with 6-minute walk test (6MWT) (eg, angina pectoris, claudication, musculoskeletal disorder, need for walking aids).
