Detailed Description
Study RIN-PF-302 is a Phase 3, multicenter, open-label extension (OLE) study for eligible subjects who completed Study RIN-PF-301 or Study RIN-PF-303 to evaluate the long-term safety and tolerability of inhaled treprostinil in subjects with idiopathic pulmonary fibrosis (IPF). Following OLE entry, subjects will return at Week 4, Week 12, and every 12 weeks thereafter for up to 6 years or until the subject prematurely discontinues study treatment due an adverse event (AE)/serious adverse event (SAE) or other reason, inhaled treprostinil becomes commercially available for IPF, or the study is discontinued by the Sponsor (whichever is sooner).
Efficacy assessments will include spirometry (forced expiratory volume in 1 second [FEV1] and forced vital capacity [FVC]), time to clinical worsening, time to first acute exacerbation of IPF, overall survival, King's Brief Interstitial Lung Disease (K-BILD) Questionnaire, plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) concentration, supplemental oxygen use, and diffusion capacity of lungs for carbon monoxide (DLCO). Safety assessments will include monitoring for the development of AEs/SAEs, vital signs, clinical laboratory parameters, and electrocardiogram (ECG) parameters. In addition, up to 24 eligible subjects may participate in a PK substudy to evaluate the systemic exposure of treprostinil after inhaled administration.

Outcome Measures
Primary Outcome Measures
- Long-term safety and tolerability of inhaled treprostinil in subjects with IPF [Baseline to 6 years]

Eligibility Criteria
Criteria
Inclusion Criteria:
-
Subject gives voluntary informed consent to participate in the study.
-
The subject participated in Study RIN-PF-301 or Study RIN-PF-303 and remained on study drug and completed all scheduled study visits or was enrolled in Study RIN-PF-301 or Study RIN-PF-303 at the time that the study or study subject was discontinued by the Sponsor.
-
Women of childbearing potential must be non-pregnant (as confirmed by a urine pregnancy test at OLE Entry Visit and Baseline) and non-lactating, and will abstain from intercourse (when it is in line with their preferred and usual lifestyle) or use 2 medically acceptable, highly effective forms of contraception for the duration of the study, and at least 30 days after discontinuing study drug.
-
Males with a partner of childbearing potential must use a condom for the duration of treatment and for at least 48 hours after discontinuing study drug.
-
In the opinion of the Investigator, the subject is able to communicate effectively with study personnel, and is considered reliable, willing, and likely to be cooperative with protocol requirements, including attending all study visits.
Exclusion Criteria:
-
Subject is pregnant or lactating.
-
In the opinion of the Investigator, enrollment in Study RIN-PF-302 would represent a risk to the subject's overall health.
