Chronic Obstructive Pulmonary Disease Clinical Trial
Official title:
A Randomised, Double-blind, Placebo-controlled Proof-of-pharmacology Study of EP395 in Healthy Adults
This study aims to assess the effect of EP395 against an induced inflammation of the lung. In addition, further data about the safety and tolerability of EP395 will be collected. To investigate the efficacy of EP395 at the end of the treatment with EP395 or placebo (dummy), all participants will inhale a lipopolysaccharide (a molecule composed of sugar and fat) that artificially induces an acute inflammation of the airways. It is assumed that participants who received EP395 will show less inflammation of the airways than participants who received placebo.
This is a study to assess the pharmacological effect of repeated doses of EP395 in healthy subjects with the aim to assess the effects of EP395 on lung and blood markers of inflammation after inhaled lipopolysaccharide (LPS), and the safety, tolerability, and systemic exposure of EP395. The study will be randomised in a 1:1 ratio to take either high dose EP395 or placebo as oral capsules once daily for 21 days starting on Day 1 with scheduled visits at Days 7, 14, and 21 for assessments of safety and tolerability and systemic exposure of EP395. At Day 21, 2 hours after the last investigational product (IP) intake, participants will undergo an inhaled LPS challenge to induce airway inflammation, which will be followed by bronchoscopy and BAL 6 hours later. A final safety follow-up visit will be performed at Day 37. If the data from the high dose EP395 arm (variability, effect size) indicate that it may be possible to detect effects on IL-8 at a lower dose of EP395, an additional lower dose EP395 arm will be added. ;
