A Multicentre Study in Otherwise Healthy Infants and Toddlers Hospitalised For and Diagnosed With RSV Lower Respiratory Tract Infection to Evaluate the Safety, Tolerability, and Clinical Activity of ALX-0171
January 9, 2019 updated by: Ablynx
A Phase I/IIa Multicentre Study in Otherwise Healthy Infants and Toddlers Hospitalised For and Diagnosed With Respiratory Syncytial Virus Lower Respiratory Tract Infection, Consisting of an Open-label Lead-in Part Followed by a Double-blind, Placebo-controlled Part, to Evaluate the Safety, Tolerability and Clinical Activity of ALX-0171, Administered Via Inhalation, in Addition to Standard of Care.
The primary objective of the study is to investigate the safety and tolerability of ALX-0171.
The secondary objectives are to evaluate the clinical effect of ALX-0171 and to explore the pharmacodynamics (PD) and the systemic pharmacokinetics (PK) of ALX-0171.
