Description
Inclusion Criteria:
- Male and female patients 18 years of age or older with symptomatic PAH.
- Subjects with PAH belonging to one of the following subgroups of the Updated Clinical Classification Group 1 (Nice, 2013):
- Idiopathic PAH
- familial PAH
- PAH associated with connective tissue disease, congenital heart disease (surgically repaired at least 12 months prior to screening) or drug or toxin induced (for example, anorexigen use).
- Subjects must have persistent symptoms due to PAH despite therapy with at least one of the following PAH medications: an endothelin receptor antagonist, asoluble guanylate cyclase stimulator or a phosphodiesterase inhibitor. The subjects' PAH medication regimen, with typical medications including calcium channel blockers, endothelin receptor antagonists, soluble guanylate cyclase stimulators and/or phosphodiesterase inhibitors, must have been used at a stable dose and frequency for at least 12 weeks before the screening visit and during the screening period.
- Diagnosis of PAH established according to the standard criteria before the screening visit:

- PVR > 240 dynes s/cm5.
- Pulmonary capillary wedge pressure or left ventricular end diastolic pressure < 15 mmHg
- PVR > 400 dynes s/cm5 at the time of the baseline right heart catheterization (RHC) (if a RHC was completed within one month of the screening visit, that result may be used for inclusion).
- 6-minute walk distance greater than 150 meters at Screening. This distance must be confirmed by a second 6MWT prior to randomization. The value of the second 6MWD should be within ± 15% of the value obtained at Screening.
Exclusion Criteria:
- Subjects with clinically unstable right heart failure within the last three months (New York Heart Association (NYHA) Class IV).
- Subjects with PAH associated with portal hypertension, Human Immunodeficiency Virus (HIV) infection or unrepaired congenital systemic to pulmonary shunts

- Hypotensive subjects (systemic systolic blood pressure < 85 mmHg)
- Subjects with a history of left sided heart disease, chronic left sided heart failure, congenital or acquired valvular disease and/or pulmonary venous hypertension.
- Subjects with significant obstructive (forced expiratory volume in one second [FEV1]/forced vital capacity [FVC] < 70% predicted) or restrictive (total lung capacity < 70% predicted) lung disease at screening.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in Pulmonary Vascular Resistance (PVR) at Week 16 (Day 111)
Time Frame: Baseline, Week 16 (Day 111)
|
The efficacy of 16 weeks of QCC374 administration in subjects with Pulmonary Arterial Hypertension (PAH) was assessed by measuring changes from baseline in Pulmonary Vascular Resistance (PVR).
PVR is derived from the CO measurement in dyn·s/cm5 and can be calculated as 80 multiplied by (Mean Arterial Pressure - Mean Pulmonary Artery Wedge Pressure) divided by Cardiac Output.
A higher negative number in Pulmonary Vascular Resistance indicates improvement.
Only descriptive analysis performed.
|
Baseline, Week 16 (Day 111)

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in Six Minute Walk Distance (6MWD) Over Time
Time Frame: Baseline, Day 28, Day 56, Day 84 and Day 111
|
The Six Minute Walk Test measures the distance an individual is able to walk over a total of six minutes on a hard, flat surface.
The goal is for the individual to walk as far as possible in six minutes.
The individual is able to self-pace and rest as needed as they traverse back and forth along a marked walkway.
Only descriptive analysis performed.
|
Baseline, Day 28, Day 56, Day 84 and Day 111
|
Change From Baseline in Cardiac Output (CO) at Week 16 (Day 111)
Time Frame: Baseline, Week 16 (Day 111)
|
The Right Heart Catheterization (RHC) assessment was performed to assess several hemodynamic variables in pulmonary hypertension, including Cardiac Output (CO).
All hemodynamic parameters were assessed when the patient was in a stable hemodynamic rest state (as demonstrated by three consecutive CO measurements within 10% of each other) while the patient was breathing ambient air or oxygen.
CO was measured in triplicate using the thermodilution technique.
Direct Fick could be used only after discussion and approval by the Sponsor.
In all cases, the same technique was to be used at baseline and week 16. .
A higher positive number in Cardiac Output indicates improvement.
Only descriptive analysis performed.
|
Baseline, Week 16 (Day 111)
|
Change From Baseline in Cardiac Index at Week 16 (Day 111)
Time Frame: Baseline, Week 16 (Day 111)
|
The Right Heart Catheterization (RHC) assessment was performed to assess several hemodynamic variables in pulmonary hypertension, including Cardiac Index.
All hemodynamic parameters were assessed when the patient was in a stable hemodynamic rest state (as demonstrated by three consecutive CO measurements within 10% of each other) while the patient was breathing ambient air or oxygen.
A higher negative number in Cardiac Index indicates improvement.
Only descriptive analysis performed.
|
Baseline, Week 16 (Day 111)
|
Change From Baseline in Pulmonary Capillary Wedge Pressure (PCWP) at Week 16 (Day 111)
Time Frame: Baseline, Week 16 (Day 111)
|
The Right Heart Catheterization (RHC) assessment was performed to assess several hemodynamic variables in pulmonary hypertension, including mean Pulmonary Capillary Wedge Pressure (PCWP).
All hemodynamic parameters were assessed when the patient was in a stable hemodynamic rest state (as demonstrated by three consecutive CO measurements within 10% of each other) while the patient was breathing ambient air or oxygen.
Pressure measurements were made in the PA, PA wedge, right ventricle (RV) and right atrium (RA) and determined at the end of normal expiration.
The PCWP was recorded as the mean of three measurements.
Only descriptive analysis performed.
|
Baseline, Week 16 (Day 111)
|
Change From Baseline in Systemic Vascular Resistance (SVR) at Week 16 (Day 111)
Time Frame: Baseline, Week 16 (Day 111)
|
The Right Heart Catheterization (RHC) assessment was performed to assess several hemodynamic variables in pulmonary hypertension, including Systemic Vascular Resistance (SVR).
All hemodynamic parameters were assessed when the patient was in a stable hemodynamic rest state (as demonstrated by three consecutive CO measurements within 10% of each other) while the patient was breathing ambient air or oxygen.
SVR is derived from the CO measurement in dyn·s/cm5 and can be calculated as 80 multiplied by (Mean Arterial Pressure - Mean Venous Pressure or CVP)) divided by Cardiac Output.
A higher negative number in Mean Systemic Vascular Resistance indicates improvement.
Only descriptive analysis performed.

Key Right Ventricular (RV) function endpoints such as RV fractional area change (RV FAC) and RV Free Wall Average Peak Long Strain (RV FWPLS) were assessed with echocardiography.
A higher number in RV FAC and a lower number in RV FWPLS indicate an improvement.
Only descriptive analysis performed.
|
Baseline, Week 16 (Day 111)
|

Time Frame: Baseline, Week 16 (Day 111)
|
Key Right Ventricular (RV) function endpoints such as Tei Index were assessed with echocardiography.
The RV Tei index is using both systolic and diastolic time intervals to evaluate the overall global dysfunction of the right ventricle in PAH patients.
A lower number in RV Tei Index indicates an improvement.
Only descriptive analysis performed.
