|Condition or disease||Intervention/treatment||Phase|
|Primary Pulmonary Hypertension||Drug: LIQ861 Inhaled Treprostinil||Phase 3|
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||121 participants|
|Intervention Model:||Single Group Assignment|
|Intervention Model Description:||
The study will evaluate the long term safety and tolerability of LIQ861 in PAH patients transitioning from stable doses of inhaled treprostinil therapy, or who are taking no more than 2 approved, non-prostacylcin, oral PAH therapies.
Patients transitioning from inhaled treprostinil will be initiated at a comparable dose of LIQ861, and then titrate in 25ug incremental doses to tolerance and symptom relief. Patients adding LIQ861 to current oral therapies will start at a 25ug dose, and increase in 25ug increments on a weekly basis to tolerance and symptom relief.
A subset of the patients transitioning from inhaled treprostinil will be enrolled in a one-directional crossover to compare the bioavailability and pharmacokinetics of treprostinil as they transition to LIQ861. Serial PK sample collections will be taken on back to back days for transitioning and LIQ861 treprostinil formulations. These patients will then continue to be followed as all other patients enrolled in the study.

Experimental: LIQ861 Inhaled Treprostinil
LIQ861 inhaled treprostinil at capsule strengths of 25 μg, 50 μg, 75 μg and 100 μg.
LIQ861 will be administered using the RS00 Model 8 dry powder inhalation (DPI) device (Plastiape S.p.A.; Osnago, Italy) at dose levels of 25 μg to 150 μg treprostinil QID in individual patients.
Drug: LIQ861 Inhaled Treprostinil
LIQ861 bulk powder is generated from a treprostinil/excipient matrix from which particles of precise size and shape are created and filled into a hydroxypropyl methylcellulose (HPMC) capsule (size 3). LIQ861 capsules are provided in capsule strengths of 25 μg, 50 μg, 75 μg and 100 μg treprostinil.
- Incidence of Treatment-Emergent Adverse Events and Serious Adverse Events [ Time Frame: Baseline, Week 2, Month 1, Month 2 Visits, with bimonthly follow up for up to 30 months. ]Treatment-Emergent Adverse Events and Serious Adverse Events will be grouped by MedDRA System Organ Class, dose level, time on drug, and relationship to dose titration
