Influenza A infections cause significant seasonal morbidity and mortality as well as periodic pandemic infections. Currently, no approved therapies exist for patients hospitalized with influenza. The efficacy of VIS410, a broadly neutralizing human immunoglobulin IgG1 monoclonal antibody engineered to bind to the stem region of group 1 and 2 influenza A hemagglutinins, was explored in experimental human influenza infection.

This study evaluated the safety and tolerability of VIS410 in non-hospitalized adult patients with uncomplicated influenza A.
Methods: Patients 18 to 65 years of age with symptom onset within 72 h were randomized 1:1:1 to receive a single intravenous infusion of VIS410 4000 mg, 2000 mg, or placebo.
Background: Pimodivir (formerly JNJ-63623872) is a novel, non-nucleoside polymerase complex inhibitor with in vitro activity against influenza A virus, including pandemic 2009 H1N1, H7N9, H5N1 strains as well as neuraminidase- and amantadine-resistant strains.
Methods: Randomized, double-blind, placebo-controlled, Phase IIa study. Healthy volunteers (n=104) were inoculated with an influenza A/Wisconsin/67/2005 (H3N2) challenge virus.
