• Do not take any systemic or topical prescription, or nonprescription (over-the-counter [OTC]) medication (acetaminophen or ibuprofen are permitted upon principal investigator [PI] discretion) within 2 weeks or 5 half-lives (whichever is longer) before first dose of the study drugs until discharge from the study (unless prescribed by the Investigator to treat an AE).

Exclusion Criteria:

• Have a history of anaphylaxis, a previous documented hypersensitivity reaction, or a clinically significant idiosyncratic reaction to any drug.
• Have a clinically significant history of neurological, cardiovascular, respiratory, endocrine, hematological, hepatic, renal, gastrointestinal, genitourinary, pulmonary, and/or musculoskeletal disease; glaucoma; a psychiatric disorder, or any other chronic disease, whether controlled by medication or not.
• Have a history of orthostatic hypotension, or unexplained syncope.
• Have a history of additional risk factors for Torsades de Pointes (eg, heart failure, family history of Long QT Syndrome).
• Are positive for human immunodeficiency virus (HIV) infection, hepatitis B surface antigen (HBsAg), or the hepatitis C virus (HCV) antibody at screening.
• Are users or former users of nicotine-containing products with > 10 pack-years of tobacco use history (including but not limited to cigarettes, cigars, and chewing or dipping tobacco), or users who stopped use or consumption (i.e., smoking, chewing, or pinching) of these nicotine-containing products less than 6 months before study drug administration or were using or had used topical or oral nicotine preparations for smoking cessation within the past 3 months before study drug administration.
• Have a history of alcohol abuse or a history of or current impairment of organ function reasonably related to alcohol abuse.
• Have a history or current evidence of abuse of licit or illicit drugs or a positive urine test for drugs of abuse.
• Have a history of abnormal bleeding tendencies.
• Donated any plasma within 7 days prior to first dosing, or has donated blood in excess of 450 mL, or had significant blood loss within 56 days prior to first dosing.
• Have any flu-like syndrome or other respiratory infection within 2 weeks of Day 1 or having been vaccinated with an attenuated live virus within 4 weeks of Day 1.
• Have a history of major surgery within 4 weeks or minor surgery within 2 weeks of screening. Note: Other inclusion/exclusion criteria may apply.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants who Experienced an Adverse Event (AE)	Safety and tolerability of escalating doses of C16TR for inhalation in healthy participants.	Up to 32 days
Secondary	Area Under the Plasma Concentration-time Curve (AUC) of Treprostinil and C16TR Post C16TR for Inhalation Dose		At multiple timepoints post dose on Days 2 to 4
Secondary	Cohort 1: AUC of Treprostinil Post Tyvaso® Dosing	Pharmacokinetics of treprostinil after Tyvaso® dosing in healthy participants will be assessed.	At multiple timepoints post dose on Days 1 and 2 for Cohort 1
Secondary	Mean Change From Baseline in Corrected QT Interval by Fridericia (QTcF) for C16TR		Baseline up to Day 4 (Cohort 1) and Day 3 (Cohorts 2, 3, 4, and 5)
