Descriptive Information
Brief Title  ICMJE Pharmacokinetics, Safety and Tolerability of Treprostinil Inhalation Powder in Healthy Normal Volunteers
Official Title  ICMJE 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
Brief Summary A Dose-Rising Clinical Trial to Evaluate the Pharmacokinetics, Safety and Tolerability of Treprostinil Inhalation Powder in Healthy Normal Volunteers
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.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  1. Voluntarily consents to participate in this study and provides written informed consent prior to the start of any study-specific procedures.
  2. Male or female. Females must not be pregnant or breastfeeding.
  3. Is between 18 and 55 years of age (inclusive).
  4. Female subjects must weigh between 55 and 100 kg, inclusive, with a body mass index (BMI) between 19.0-32.0 kg/m2, inclusive. Male subjects must weigh between 55 and 120 kg, inclusive, with a BMI between 19.0-32.0 kg/m2, inclusive.
  5. Females must be of non-childbearing potential (defined as surgically sterile [i.e. had a bilateral tubal ligation, hysterectomy, or bilateral oophorectomy at least 6 months prior to the first dose of study medication] or postmenopausal for at least 1 year prior to the first dose of study medication) or agree to use an acceptable form of birth control (see Section 4.4) from screening until 14 days after study completion.
  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.
