Description of intervention(s) / exposure
Treatment: Drugs - Treprostinil Palmitil
Treatment: Drugs - Placebo

Experimental: Treprostinil Palmitil - Participants will be administered TPIP once per day at a starting dose of 80 micrograms (µg). Participants will be titrated up to the highest tolerated dose for each individual participant of between 80 µg and 640 µg during the initial 3 weeks of treatment. The overall treatment period will be 16 weeks.

Placebo comparator: Placebo - Participants will be administered a placebo matching TPIP once daily.


Treatment: Drugs: Treprostinil Palmitil
Oral inhalation using a capsule-based dry powder inhaler device.

Eligibility
Key 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.
Minimum age
18 Years
Maximum age
80 Years

* 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.
