Trial outcomes

Primary outcomes

1

Change in pulmonary vascular resistance (PVR) at week 24

PVR is a hemodynamic variable of pulmonary circulation measured by right heart catheterization (RHC).

Time frame
From baseline to week 24
2

Number of participants who experienced an adverse event (AE) up to approximately 24 weeks.

An AE is any untoward medical occurrence in a study participant administered a study drug, which did not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of the study drug. whether or not it was considered related to the study drug.

Time frame
From baseline to week 24

Secondary outcomes

1

Change in hemodynamic parameters at Week 24

The hemodynamic parameters include mean right atrium pressure, mean pulmonary arterial pressure, systolic pulmonary artery pressure, diastolic pulmonary arterial pressure, cardiac output, pulmonary artery wedge pressure, stroke volume, and mixed venous oxygen saturation. The hemodynamic parameters will be used to calculate PVR, cardiac index, PVR index, total peripheral resistance, stroke volume index, and pulmonary artery compliance.

Time frame
From baseline to week 24
2

Change in 6-minute walk distance (6MWD) at weeks 12 and 24

The 6MWD is the distance walked in 6 minutes as a measure of functional capacity. This will be assessed using the 6-minute walk test (6MWT).

Time frame
From baseline to weeks 12 and 24
3

Change in Borg dyspnea scale at Week 12 and 24

Borg dyspnea scale is a measure used to assess an individual's exertion level during physical activity after the 6MWT

Time frame
From baseline to weeks 12 and 24
4

Change in Word Health Organization Functional Classification (WHO FC) at weeks 12 and 24

The WHO FC describes the severity of symptoms and limitations in physical activity according to the following classes: * Class I: No symptoms and no limitation in ordinary physical activity. * Class II: Mild symptoms and slight limitation during ordinary activity. * Class III: Marked limitation in activity due to symptoms, even during less-than-ordinary activity. * Class IV: Severe symptoms experienced at rest, with inability to carry out any physical activity without discomfort

Time frame
From baseline to weeks 12 and 24
