Outcomes

Primary Outcome Measures

Phase 2 Cohort: Change from Baseline in Pulmonary Vascular Resistance (PVR) at 12 Weeks
PVR is assessed by right heart catheterization (RHC).
Phase 3 Cohort: Change from Baseline in 6-Minute Walk Distance (6MWD) at 12 Weeks
6MWD is assessed using the 6-minute walk test (6MWT).

Secondary Outcome Measures

Phase 2 Cohort: Change from Baseline in 6-Minute Walk Distance (6MWD) at 12 Weeks
6MWD is assessed using the 6-minute walk test (6MWT).
Phase 2 Cohort: Change from Baseline in Mean Right Arterial Pressure (mRAP) at 12 Weeks
mRAP is assessed by right heart catheterization (RHC).
Phase 2 Cohort: Change from Baseline in Cardiac Index (CI) at 12 weeks
Cardiac index is assessed by right heart catheterization (RHC).
Phase 2 Cohort: Change from Baseline in Stroke Volume Index (SVI) at 12 weeks
SVI is assessed by right heart catheterization (RHC).
Phase 3 Cohort: Change from Baseline in 6-Minute Walk Distance (6MWD) at 24 Weeks
6MWD is assessed using the 6-minute walk test (6MWT).
Phase 3 Cohort: Change from Baseline in World Health Organization Functional Class (WHO-FC) at 12 Weeks
Participants are assigned one of four WHO-FC, dependent on limits of physical activity. As WHO-FC increases from I to IV, limits of physical activity increase.
Phase 2 Cohort: Number of Participants Who Experience an Adverse Event
An adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention.
Phase 2 Cohort: Number of Participants Who Discontinue Study Drug Due to an Adverse Event
An adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention.

5. Study Description

Brief Summary
This is a two-part (Phase 2/Phase 3) study of MK-5475, an inhaled soluble guanylate cyclase stimulator, in participants with pulmonary arterial hypertension (PAH). The first part (Phase 2) will assess three different doses of MK-5475 compared to placebo in a base period of 12 weeks, followed by comparison of three different doses of MK-5475 during an optional 24 month extension period. The treatment dose with the best efficacy and safety profile in the phase 2 cohort base period will be selected for use in the second part (Phase 3) of the study. The primary hypothesis of Phase 2 is that at least one MK-5475 dose is superior to placebo in reducing pulmonary vascular resistance (PVR) from baseline at week 12. The purpose of the second part (Phase 3) of the study is to confirm the efficacy, safety, and tolerability of MK-5475 at the selected dose compared to placebo during a 12 week base period followed by an extension period of up to 5 years. The primary hypothesis of Phase 3 is that MK-5475 is superior to placebo in increasing 6-minute walk distance (6MWD) from baseline at week 12.
