Notes to Editors

Avacta Group plc (www.avacta.com)

Avacta's principal focus is on its proprietary Affimer® technology which is a novel engineered alternative to antibodies that has wide application in Life Sciences for diagnostics, therapeutics and general research and development.

Antibodies dominate markets worth in excess of $75bn despite their shortcomings. Affimer technology has been designed to address many of these negative performance issues, principally; the time taken to generate new antibodies, the reliance on an animal's immune response, poor specificity in many cases, and batch to batch variability. Affimer technology is based on a small protein that can be quickly generated to bind with high specificity and affinity to a wide range of targets to enable diagnostics, research assays and therapeutics.

Avacta has a pre-clinical therapeutic development programme with an in-house focus on immuno-oncology and bleeding disorders as well as partnered development programmes. Avacta is commercialising non-therapeutic Affimer reagents through licensing to developers of life sciences research tools and diagnostics.
