Brief Summary

This is a Phase 1, randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability and pharmacokinetics of a single ascending doses (SAD) and multiple ascending doses (MAD) of Hypothiocyanite (OSCN-), bovine lactoferrin (bLF) and their combination (ALX-009) in healthy male volunteers and patients suffering from cystic fibrosis (CF) and non-CF bronchiectasis (NCFBE).

Detailed Description

Part I: SAD of OSCN- and bLF in healthy male volunteers (cohorts 1 to 3) - Part II: SAD and MAD of ALX-009 in healthy male volunteers (cohorts 4 and 5) - Part III: MAD of OSCN- and bLF in patients suffering from cystic fibrosis (cohort III-1) and in healthy volunteers (cohorts III-2 and III-3) - Part IV: MAD of ALX-009 in healthy volunteers (Part IVa - Cohorts IV-1a to IV-3a) and in patients (Part IVb - Cohorts IV-1b to IV-3b)
