SENIOR SCIENTIST / PRINCIPAL SCIENTIST - PROTEIN SCIENCES About Maxion Maxion Therapeutics is a biotechnology company developing antibody-based drugs for previously untreatable ion channel- and G protein-coupled receptor (GPCR)-driven diseases, including autoimmune conditions, chronic pain, and cardiovascular disease. The Company is developing a pipeline of potentially first- and best-in-class therapeutics using its proprietary KnotBody® technology to generate potent, selective, and long-acting therapeutics by combining naturally occurring mini-proteins (‘knottins’) with antibodies using state-of-the-art phage and mammalian display technologies. Maxion was founded in 2020 by highly respected biotech entrepreneurs and scientists Dr John McCafferty, CTO and Dr Aneesh Karatt-Vellatt, CSO. Dr McCafferty previously co-invented antibody phage display, which was the subject of the 2018 Nobel Prize in Chemistry awarded to his co-inventor Sir Gregory Winter. Maxion’s portfolio and growth is being advanced by a team of highly experienced leaders in the discovery and development of antibody-based drugs. The Company is based near Cambridge, UK and is backed by international blue-chip investors. For more information, please visit: https://www.maxiontherapeutics.com/.
