简要总结
Study RIN-PF-302 is designed to evaluate the long-term safety and tolerability of inhaled treprostinil in subjects with idiopathic pulmonary fibrosis or progressive pulmonary fibrosis.
详细描述
Study RIN-PF-302 is a Phase 3, multicenter, open-label extension (OLE) study for eligible subjects who completed Study RIN-PF-301, Study RIN-PF-303, or Study RIN-PF-305 to evaluate the long-term safety and tolerability of inhaled treprostinil in subjects with idiopathic pulmonary fibrosis (IPF) or progressive pulmonary fibrosis (PPF). 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 PPF, 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 or interstitial lung disease (ILD), 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 with IPF rolling over from Study RIN-PF-301 and up to 24 eligible subjects with PPF rolling over from Study RIN-PF-305 may participate in a PK substudy to evaluate the systemic exposure of treprostinil after inhaled administration.

入选标准
- •Subject gives voluntary informed consent to participate in the study.
- •The subject participated in Study RIN-PF-301, Study RIN-PF-303, or Study RIN-PF-305 and remained on study drug and completed all scheduled study visits or was enrolled in Study RIN-PF-301, Study RIN-PF-303, or Study RIN-PF-305 at the time that the study or study subject was discontinued by the Sponsor for reasons other than safety.
- •Women of childbearing potential must be non-pregnant (as confirmed by a urine pregnancy test at OLE Entry Visit) and non-lactating, and will agree to 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 agree to 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.
排除标准
- •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.
- •Use of any other investigational drug/device or participation in any investigational study in which the subject received a medical intervention (ie, procedure, device, medication/supplement). Subjects participating in non-interventional, observational, or registry studies are eligible.
