| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Prostacyclin Receptor Agonist | Experimental | Participants in Cohort 1-7 will receive multiple doses of prostacyclin receptor agonist of formulation 1 in treatment period 1, followed by a single dose of various other formulations (formulation 2, 3, and 4) in treatment period 2. Cohort 7 will be optional. Doses in Cohorts 4, 5, 6 and cohort 7 will be based on PK, safety and tolerability data of previous 3 cohorts (preceding cohorts). |

| Measure | Description | Time Frame |
|---|---|---|
| Number of Participants with Treatment-emergent Adverse Events (TEAEs) | An adverse event is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product. TEAEs are defined as AEs with onset or worsening on or after date of first dose of study treatment. | Up to 114 days |
| Number of Participants With Serious TEAEs | A SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Serious TEAEs are defined as serious events between administration of study drug and after the last dose that were absent before treatment or that worsen relative to pretreatment state. | Up to 114 days |
| Number of Participants with TEAEs by Severity | Number of participants with TEAEs by severity will be evaluated. An assessment of severity grade will be made using the following general categorical descriptors, such as Mild (Awareness of symptoms that are easily tolerated, causing minimal discomfort, and not interfering with everyday activities), Moderate (Sufficient discomfort is present to cause interference with normal activity), and Severe (Extreme distress, causing significant impairment of functioning or incapacitation, and prevents normal everyday activities). | Up to 114 days |
| Number of Participants with TEAEs Leading to Discontinuation | Number of participants with TEAEs leading to discontinuation will be reported. | Up to 114 days |
| Number of Participants With Change from Baseline in Clinical Laboratory Values |
| Measure | Description | Time Frame |
|---|---|---|
| Treatment Period 1: Maximum Observed Plasma Concentration of Prostacyclin Receptor Agonist at Steady State (Cmax[ss]) | Cmax(ss) is the maximum observed plasma concentration of prostacyclin receptor agonist at steady state, during treatment period 1. | Up to 114 days |
| Treatment Period 1: Time to Reach Maximum Observed Plasma Concentration of Prostacyclin Receptor Agonist at Steady State (Tmax[ss]) |
