Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This open-label study will evaluate the safety of continued therapy with inhaled treprostinil in participants who have completed Study RIN-PH-304 (NCT03496623). This study hypothesizes that long-term safety findings will be similar to those observed in the randomized, placebo-controlled, double-blind, adaptive study 'A Phase 3, Randomized, Placebo-controlled, Double-blind, Adaptive Study to Evaluate the Safety and Efficacy of Inhaled Treprostinil in Patients with Pulmonary Hypertension due to Chronic Obstructive Pulmonary Disease (PH-COPD)(RIN-PH-304).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a multi-center, open-label study for eligible participants who completed all scheduled study visits during the Treatment Period of Study RIN-PH-304.

Participants who provide informed consent for this open-label extension study on or prior to the final study visit of RIN-PH-304 may participate in the study, provided all other eligibility criteria are met. The RIN-PH-304 final study visit and the RIN-PH-305 Enrollment Visit will occur on the same day.

All participants will reinitiate inhaled treprostinil at 3 breathes (18 micrograms \[mcg\]) 4 times daily (QID) during waking hours. Study drug doses should be maximized to tolerability throughout the study, and dose titrations should occur as rapidly as possible (as directed by the Investigator) with a target dosing regimen of 15 breaths QID or the maximum tolerated dose.
