Cough Associated With Idiopathic Pulmonary Fibrosis Clinical Trial
A DOUBLE-BLIND, RANDOMISED, PLACEBO CONTROLLED, TWO PERIOD CROSS-OVER STUDY TO EVALUATE THE EFFICACY AND SAFETY OF ORVEPITANT IN CHRONIC COUGH IN PATIENTS WITH IDIOPATHIC PULMONARY FIBROSIS
ORV-PF-01 is a two way, placebo controlled, cross-over study, to evaluate the effect of two doses of orvepitant on cough in patients with IPF.
The study will be a multi-center, double-blind, randomised, placebo-controlled 2-period cross-over study in subjects with chronic cough due to idiopathic pulmonary fibrosis (IPF). Subjects will participate in one of two cohorts (Cohort 1 and Cohort 2). Cohort 1 will evaluate a 30 mg orvepitant dose and Cohort 2 the 10 mg dose. Within each cohort, subjects will be randomised to receive either orvepitant or placebo in the first treatment period (Treatment Period A) followed by the alternate treatment in Treatment Period B. There will be a wash-out period of 3 weeks between the two treatment periods. Subjects will be randomised 1:1 to each of the two treatment orders and 1:1 to each cohort. Subjects will enter a screening period of between 14 and 28 days to determine eligibility. Eligible subjects will be randomised at the Baseline visit and will participate in two identical 28 day treatment periods with the wash-out period between them. There will be a total of 8 visits including the Screening, Baseline and final Follow-up visits. ;
