- Target Recruitment
- 88
- Otherwise, healthy as deemed by the investigator on the basis of physical examination, medical history, vital signs, and 12-lead electrocardiograms (ECG) performed at Screening and Day -1 of oral treatment period
- Otherwise, healthy medically stable on the basis of clinical laboratory tests performed at screening. If the results of the serum chemistry panel, blood coagulation, hematology, or urinalysis are outside the normal reference ranges, the participant may be included only if the investigator judges the abnormalities or deviations from normal to be not clinically significant or to be appropriate and reasonable for the population under study. This determination must be recorded in the participant's source documents and initialed by the investigator
- Body mass index (BMI) within the range 18.0 to 32.0 kilograms per meter square (kg/m^2) (inclusive) and body weight not less than 50 kilograms (kg) at screening
- All female participants must have a negative highly sensitive serum (beta-human chorionic gonadotropin [beta-hCG]) at screening
- A male participant must agree not to donate sperm for the purpose of reproduction during the study and for a minimum of 90 days after receiving the last dose of study intervention
- Known allergies, hypersensitivity, anaphylaxis, or intolerance to prostacyclin receptor agonist or drugs of the same class, or any excipient (including poloxamer and polysorbate) of the drug formulation(s)
- Clinically significant abnormal physical examination, vital signs, or 12-lead ECG (QTc greater than or equal to [>=]450 milliseconds [msec] for men and >=460 msec for women. QT corrected according to Bazett's formula [QTcB]) as assessed by the Investigator at Screening or Day -1 of oral treatment period
- History of malignancy within 3 years before screening (exceptions are squamous and basal cell carcinomas of the skin
- Positive serologic testing for human immunodeficiency virus (HIV), hepatitis B surface antigen (hBsAg), hepatitis C virus (HCV), active coronavirus disease 2019 (COVID-19) infection
- A history of repeated (more than once over the last 30 days) fainting due to cardiac cause, collapse, syncope, orthostatic hypotension, or vasovagal reactions

Group Intervention Description Prostacyclin Receptor Agonist Prostacyclin Receptor Agonist 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).
- Primary Outcome Measures
Name Time Method Number of Participants With Change from Baseline in Clinical Laboratory Values Up to 114 days Number of participants with change from baseline in clinical laboratory values (chemistry, hematology, and urinalysis) will be evaluated.
Number of Participants with Treatment-emergent Adverse Events (TEAEs) Up to 114 days 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.
Number of Participants With Serious TEAEs Up to 114 days 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.
Number of Participants With Injection Site Reactions Up to 114 days Number of participants with injection site reactions will be evaluated.
Number of Participants with TEAEs by Severity Up to 114 days 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).
Number of Participants with TEAEs Leading to Discontinuation Up to 114 days Number of participants with TEAEs leading to discontinuation will be reported.
