Brief Summary:
A Dose-Rising Clinical Trial to Evaluate the Pharmacokinetics, Safety and Tolerability of Treprostinil Inhalation Powder in Healthy Normal Volunteers

Condition or disease Intervention/treatment Phase
Pulmonary Arterial Hypertension Drug: Treprostinil Inhalation Powder Phase 1

Detailed Description:

Up to 48 subjects will be enrolled in 8 cohorts of 6 subjects each. The treatments are intended to establish the maximum tolerated dose in healthy normal volunteers, starting at 30 mcg. Each subject will receive one dose of Treprostinil Inhalation Powder by oral inhalation during the treatment period.

A total of 12 pharmacokinetic blood samples will be collected from each subject. Plasma pharmacokinetic samples will be analyzed for treprostinil.


Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 48 participants
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Other
Official Title: A Phase 1, Single-center, Open-label, Dose-Rising Clinical Trial to Evaluate the Pharmacokinetics, Safety and Tolerability of Treprostinil Inhalation Powder (TrIP) in Healthy Normal Volunteers
Actual Study Start Date : March 9, 2018
Estimated Primary Completion Date : September 2018
Estimated Study Completion Date : December 2018

Primary Outcome Measures :
  1. Incidence and severity of treatment-related adverse events (safety and tolerability) of single ascending doses of Treprostinil Inhalation Powder [ Time Frame: At protocol-specified time points from the time of screening (day 0) to end of study (day 6) ]
    Incidence and severity of treatment-related adverse events determined by changes from screening (baseline) of findings from physical examinations, laboratory evaluations, vital signs measurements, pulmonary testing, and ECG measurements.


Secondary Outcome Measures :
  1. Systemic exposure and pharmacokinetics of treprostinil administered as Treprostinil Inhalation Powder in healthy normal volunteers [ Time Frame: At protocol-specified time points throughout day 1 ]
    Concentration of treprostinil in blood as measured by protocol-specified pharmacokinetic parameters (eg maximum concentration, time to maximum concentration).

  2. Dose proportionality [ Time Frame: 10 months ]
    Dose proportionality of increasing doses of Treprostinil Inhalation Powder in healthy normal volunteers as measured by maximum blood concentration of treprostinil.

  6. Medical history, physical examination, oropharyngeal examination, vital signs, ECG, spirometry, and clinical laboratory results within normal limits or considered not clinically significant by the Investigator at screening.

Exclusion Criteria:

  1. History or presence of clinically significant cardiovascular, pulmonary, hepatic, renal, hematologic, gastrointestinal, endocrine, immunologic, dermatologic, neurologic, oncologic, or psychiatric disease or any other condition that, in the opinion of the Investigator, would jeopardize the safety of the subject or the validity of the study results.
  2. A clinically significant abnormal finding on the physical exam, medical history, electrocardiogram (ECG), or clinical laboratory results at screening.
  3. History of chronic lung disease such as asthma, chronic obstructive pulmonary disease (COPD), cystic fibrosis, interstitial lung disease, pulmonary fibrosis, etc.
  4. History of migraine headaches.
  5. History of a bleeding abnormalities (i.e., gingival bleeding, epistaxis, or blood on toilet paper, etc.) that is judged to be significant by the Investigator.

  7. History of anaphylaxis, a documented hypersensitivity reaction, or a clinically significant idiosyncratic reaction to any drug.
  8. Has been on a significantly abnormal diet (as determined by the Investigator) during the 4 weeks preceding the first dose of study medication.
