Overview
Brief Summary
This is a multicenter, double-blind, randomized, placebo-controlled Phase 3 study, to assess the efficacy and safety of BPS-314d-MR when added-on to inhaled treprostinil (Tyvaso®)in patients with pulmonary arterial hypertension.
Patients new to Tyvaso, will enter a run-in period on inhaled treprostinil until 90 days of experience is achieved to ensure drug tolerability before enrolling in the study.
Treatment groups consist of one active and one placebo group. Subjects will be randomly allocated in a 1:1 ratio to one of the two treatment groups.

Outcomes
Primary Outcomes
Number of Participants That Experienced Clinical Worsening
Time Frame: up to 144 weeks
The number of participants that experienced a Clinical Worsening event confirmed by Endpoint Adjudication Committee at First Maximum Severity. Clinical Worsening was defined as any of these events following the Baseline visit: Death (all causes); Hospitalization due to worsening PAH; Initiation of a parenteral (infusion or sub-cutaneous) prostacyclin, directly related to worsening PAH; Disease progression; Unsatisfactory long-term clinical response. The number of participants that experienced clinical worsening is presented; time to clinical worsening data was not measured. Given the rate of clinical worsening overall and the large number of censored observations at the end of the study, the mean survival time estimates were not available for this endpoint.
Secondary Outcomes
- Mean Change From Baseline in Borg Dyspnea Score at Week 24(Baseline and Week 24)
- Mean Change From Baseline in NT-pro-BNP Levels at Week 24(Baseline and Week 24)
- Change in WHO Functional Class From Baseline to Week 24(Baseline and Week 24)
- Mean Change From Baseline in Six Minutes Walk Distance (6MWD) at Week 24(Baseline and Week 24)
- Number of Participants With TEAEs, Serious TEAEs, Investigations SOC TEAEs, and Serious Investigations SOC TEAEs(up to 144 weeks)
