1. Age = 18 years
2. Documented diagnostic right heart catheterization (RHC) within 12 months of screening documenting a minimum PVR of = 4 Wood units and pulmonary capillary wedge pressure (PCWP) or left ventricular end-diastolic pressure (LVEDP) of = 15 mmHg, with the diagnosis of WHO PAH Group 1 in any of the following subtypes:
- Idiopathic PAH
- Heritable PAH
- Drug/toxin-induced PAH
- PAH associated with connective tissue disease
- PAH associated with simple, congenital systemic-to-pulmonary shunts at least 1 year following repair
3. Symptomatic PAH classified as WHO FC II or III
4. REVEAL Lite 2 risk score = 6
5. Diagnosis of PAH within 12 months of screening and on stable doses of a double or triple combination of background PAH therapies and diuretics for at least 90 days prior to screening. Background PAH therapy and diuretics are further defined in Section 7.2.
6. Six-minute walk distance = 150 m repeated twice at screening at least 4 hours apart, but no longer than 1 week apart, and both values are within 15% of each other (calculated from the highest value)
7. Females of childbearing potential must meet the following criteria:
-Have 2 negative urine or serum pregnancy tests as verified by the investigator prior to starting study drug administration; she must agree to ongoing urine or serum pregnancy testing during the course of the study and until 8 weeks after the last dose of the study drug
-If sexually active, with a male partner:
- Used highly effective contraception without interruption, for at least 28 days prior to starting the investigational product, AND
- Agreed to use the same highly effective contraception in combination with a barrier method during the study (including dose interruptions), and for 16 weeks (112 days) after discontinuation of study treatment
-Refrain from breastfeeding a child or donating blood, eggs, or ovum for the duration of the study and for at least 16 weeks (112 days) after the last dose of study treatment
8. Male participants must meet the following criteria:
-Agree to use a condom, defined as a male latex condom or nonlatex condom NOT made out of natural (animal) membrane (e.g., polyurethane), during sexual contact with a pregnant female or a female of childbearing potential while participating in the study, during dose interruptions, and for
at least 16 weeks (112 days) following investigational product discontinuation, even if he has undergone a successful vasectomy
-Refrain from donating blood or sperm for the duration of the study and for 16 weeks (112 days) after the last dose of
study treatment
9. Ability to adhere to study visit schedule and understand and comply with all protocol requirements
10. Ability to understand and provide written informed consent

1. Diagnosis of pulmonary hypertension (PH) WHO Groups 2, 3, 4, or 5
2. Diagnosis of the following PAH Group 1 subtypes: human immunodeficiency virus (HIV)-associated PAH, PAH associated with portal hypertension
chistosomiasis-associated PAH, pulmonary veno-occlusive disease and pulmonary capillary hemangiomatosis.
3. Hemoglobin at screening above gender-specific upper limit of normal (ULN), per local laboratory test
4. Uncontrolled systemic hypertension as evidenced by sitting systolic blood pressure (BP) > 160 mmHg or sitting diastolic BP > 100 mmHg during the Screening Visit after a period of rest
5. Baseline systolic BP < 90 mmHg at screening
6. Pregnant or breastfeeding women
7. Any of the following clinical laboratory values at the Screening
Visit:

10. History of pneumonectomy
11. Pulmonary function test values of forced vital capacity < 60% predicted within 1 year prior to the Screening Visit
12. Stopped receiving any PH chronic general supportive therapy (e.g., diuretics, oxygen, anticoagulants, and
digoxin) within 60 days prior to the Screening Visit
13. Initiation of an exercise program for cardiopulmonary rehabilitation within 90 days prior to the Screening Visit or
planned initiation during the study (participants who are stable in the maintenance phase of a program and who will continue for the duration of the study are eligible)
