Detaillierte Beschreibung
SMI-PH-201 is a Phase 2, randomized, double-blind, placebo-controlled, parallel-group, multicenter, safety and tolerability study with secondary endpoints evaluating the efficacy of the study drug on exercise capacity and NT-proBNP.
Eligible participants will be randomly assigned 1:1 to treprostinil SMI or placebo at the Baseline Visit and receive study drug over a 16-week period. Participants will return to the clinic for follow-up visits at Weeks 4, 8, 12, 15, and 16.
Study drug will be administered via a combination drug-device product that consists of the SMI with an associated cartridge containing a propellant-free, liquid-based formulation of treprostinil inhalation spray. Participants will receive study drug in multi-use cartridges containing either treprostinil (in concentrations of 1.34, 2.68, 4.02, and 5.36 mg/mL) or placebo.

- Use medically acceptable, highly effective contraception for the duration of the study and at least 30 days after discontinuing study drug. Medically acceptable, highly effective forms of contraception include approved hormonal contraceptives (oral, injectable, transdermal, intravaginal, and implantable), hormonal or non-hormonal intrauterine devices or systems, or monogamous intercourse with a partner who has undergone vasectomy. Barrier methods alone or with spermicide may be considered with Sponsor approval if they have a proven track record of excellent compliance. Note: Women who are successfully sterilized (including hysterectomy, bilateral salpingectomy, bilateral tubal occlusion, or bilateral oophorectomy) or postmenopausal (defined as amenorrhea for at least 12 consecutive months and >50 years of age or in the documented clinical opinion of a Women's Health Specialist) are not considered to be WOCBP for study purposes.

-
In the opinion of the Investigator, able to communicate effectively with study site staff, and considered reliable, willing, and likely to be cooperative with protocol requirements, including attending all study visits
Exclusion Criteria:
-
6MWD <150 meters during Screening

-
Evidence of clinically significant left-sided heart disease (including, but not limited to, left ventricular ejection fraction <40% and/or left ventricular hypertrophy) or clinically significant cardiologic conditions, such as congestive heart failure, coronary artery disease, or valvular heart disease. Note: Participants with abnormal left ventricular function attributable to the effects of right ventricular overload will not be excluded, but a discussion with and approval by the Sponsor's Medical Monitor is required.
-
Any form of congenital heart disease (repaired or unrepaired) other than a patent foramen ovale
-
Recent exacerbation of COPD and/or active pulmonary or upper respiratory infection that required hospitalization, symptomatic treatment, or treatment with antibiotics and/or corticosteroids:

Initiation of pulmonary rehabilitation within 12 weeks prior to Baseline or, in the opinion of the Investigator, pulmonary rehabilitation is likely to be needed during the Treatment Period

Change in peak 6-Minute Walk Distance (6MWD) from baseline to Week 16
Zeitfenster: 16 weeks
|
The intent of the 6MWD test is to evaluate exercise capacity associated with carrying out activities of daily living. Change in 6MWD from baseline to Week 16 correlates with the current clinical standard for assessing patient functional status in the treatment of PH and is considered an objective measure of patient functional status. Participants will be instructed to walk down a corridor at a comfortable speed as far as they can manage for six minutes. Peak exposure 6MWD will occur by conducting the 6-minute walk test within 10 to 60 minutes after the most recent dose of study drug. |

Incidence of acute exacerbations of COPD
Zeitfenster: 16 weeks
|
An acute exacerbation of COPD is defined as an event characterized by increased dyspnea and/or cough and sputum that worsens in <14 days, which may be accompanied by tachypnea and/or tachycardia, and is often associated with increased local and systemic inflammation caused by infection, pollution, or other insult to the airways. For this study, the following diagnostic criteria will be used to support a diagnosis of acute COPD exacerbation:
