Avacta is the proprietary owner of Affimer technology for the development of biotherapeutics, diagnostic tests and research reagents. Affimers represent a radical alternative to established antibody technology which dominates the drug industry despite its limitations. During 2016, Avacta made considerable progress towards its strategic goal to have a first-in-man Affimer therapeutic by the end of 2019. During coming weeks the company is expected to report on the next step in the pre-clinical development process: whether or not Affimer scaffolds are immunogenic. A positive outcome would be a low immune response rate.
