"Origins of Allergic Disease: Microbial, Epithelial and Immune Interactions"

TAHOE CITY (CA), USA – March 24 - 27, 2019

Paris and Boston, March 21, 2019 – 07h30am CET -Neovacs(Euronext Growth Paris : ALNEV), a leader in active immunotherapies for the treatment of autoimmune diseases, today announced the presentation of the preclinical results of its proof of concept in allergy with its new IL-4 / IL-13 Kinoid therapeutic vaccine, during the poster session at the upcoming Keystone allergy conference , taking place March 24 – 27, 2019, in Tahoe City, California, United States.

This work conducted in collaboration with a research team from the Institut Pasteur (Dr. Laurent Reber and Dr. Pierre Bruhns), showed in a representative allergic asthma model that a treatment with IL-4 / IL-13 Kinoid enhanced the production of polyclonal antibodies which neutralized the two targeted cytokines IL-4 and IL-13, both being development factors for allergic asthma, thus avoiding the occurrence of any symptoms.
