Extension Study of Inhaled Treprostinil in Subjects With Idiopathic Pulmonary Fibrosis — TETON-OLE  

Idiopathic Pulmonary Fibrosis Clinical Trial

Official title:
An Open-label Extension Study of Inhaled Treprostinil in Subjects With Idiopathic Pulmonary Fibrosis

Clinical Trial Summary

Study RIN-PF-302 is designed to evaluate the long-term safety and tolerability of inhaled treprostinil in subjects with idiopathic pulmonary fibrosis.

Clinical Trial 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. ;
