July 12, 2018 updated by: Ablynx

Phase I, Single-centre, Randomised, Placebo-controlled, Double-blinded Study, With Single Ascending Dose and Multiple Dose at Maximum Tolerated Dose, Evaluating the Safety, Tolerability and Pharmacokinetics of ALX-0171, Administered by Pulmonary Inhalation, in Healthy Male Volunteers

ALX-0171 is a Nanobody directed against the human respiratory syncytial virus (RSV). The purpose of this first-in-man study is to determine the safety, tolerability and pharmacokinetics (PK) of ALX-0171 after single and multiple pulmonary administrations in healthy male volunteers.
