A Study to Investigate Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Single Dose in Healthy Volunteers, Repeat Doses in Asthmatic Patients and of Single Dose in COPD Patients of CHF6366

• Status: Completed
• Trial end date: 2019-04-16
• Target enrollment: 0
• Participant gender: All

Summary

CHF6366 is a novel bifunctional compound displaying both muscarinic receptor antagonist and β2-adrenergic receptor agonist properties (MABA), with the potential to deliver optimal bronchodilation after inhalation dosing via two validated mechanisms in one molecule.

The study will consist of three parts:

Part 1 will consit of two cohorts of healthy male subjects to assess the safety, tolerability and pharmacokinetics of Single Ascending Dose (SAD) of CHF 6366

Part 2 will consist of four cohorts of asthmatic subjects to assess the saftey, tolerability and pharmacokinetics of Multiple Ascending Dose (MAD) of CHF6366

Part 3 will consist of one cohort of COPD patients to asess safety, tolerability of a single dose of CHF6366 in an active and placebo controlled design
