• « Antibodies and Complement 2019 » - Girona, Spain- May 20-25, 2019
• « EAACI 2019 » - Lisbon, Portugal, June 1-5 2019

Paris and Boston, May 16, 2019 – Neovacs - 07h30 am CEST - (Euronext Growth Paris : ALNEV), a leader in active immunotherapies for the treatment of autoimmune diseases, today announced the presentation of the pre-clinical results of its proof of concept in allergy with its new IL-4 / IL-13 Kinoid therapeutic vaccine, at two majors scientific congresses:

• « Antibodies and Complement 2019 » conference, in Girona, Spain May 20-25, 2019. This event will focus attention on key advances in both fields: "Antibodies and Complement".
• European Academy of Allergy and Clinical Immunology Annual Congress 2019 "EAACI 2019", to be held in Lisbon, Portugal – June 1-5, 2019, under the theme: "Mapping the new world of allergy (towards precision medicine in allergy and asthma)".

Eva Conde (Neovacs) and Dr. Laurent Reber from the research team Inserm Unit 1222, Institut Pasteur, will present during an oral session the results of this collaborative work. It has been demonstrated in a representative allergic asthma model that a treatment with IL-4 / IL-13 Kinoid enhanced the production of polyclonal antibodies, which neutralize the two targeted cytokines IL-4 and IL-13, both being development factors for allergic asthma, thus avoiding the occurrance of any symptoms.
