An Open-Label Extension Study of Treprostinil Palmitil Inhalation Powder (TPIP) in Participants With Pulmonary Hypertension Associated With Interstitial Lung Disease (PH-ILD)

Purpose

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 INS1009-311 (NCT07179380).

Conditions

  • Pulmonary Hypertension
  • Interstitial Lung Disease

Eligibility

Eligible Ages
Over 18 Years
Eligible Sex
All
Accepts Healthy Volunteers
No

Inclusion Criteria

  • Participants who have completed the lead-in PH-ILD TPIP Study INS1009-311 (NCT07179380). - 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. - Agree not to participate in any other interventional trials or use investigational drugs or devices while participating in the INS1009-312 study.

Exclusion Criteria

  • Participants who experienced any adverse events (AEs) evaluated as causally related to TPIP by the Investigator in a lead-in study, which in the opinion of the Investigator, could pose an unreasonable risk of continued treatments for the participant. - Current use or expected need for pulmonary arterial hypertension (PAH)-approved therapy, including prostacyclin, prostacyclin analogues or other prostacyclin receptor agonists, endothelin receptor antagonists, and/or soluble guanylate cyclase stimulator, or any PH-ILD approved treprostinil therapy. Use of phosphodiesterase 5 inhibitors in line with applicable guidelines is allowed. - Diagnosis of Pulmonary Hypertension World Health Organisation (WHO) Groups 1, 2, 4, or 5, or subtypes of PH WHO Group 3 other than interstitial lung disease (including combined pulmonary fibrosis and emphysema). - Evidence of left ventricular failure, heart failure with preserved ejection fraction (HFpEF) or postcapillary PH. - Known hypersensitivity or contraindication to treprostinil or TPIP or TPIP formulation excipients (eg, mannitol, leucine). Note: Other protocol-defined inclusion/exclusion criteria may apply.

Treprostinil Palmitil Inhalation Powder (TPIP)
Participants transitioning from study INS1009-311 (NCT07179380) will undergo an initial double-dummy titration with the stable dose from the lead-in study and either TPIP or placebo for 4 weeks. They will then receive open-label TPIP at a stable maintenance dose with optional escalation (80-1280 micrograms once daily) for the remainder of the 104-week treatment period.
