About Maxion

Maxion has engineered a new class of biologics by harnessing knottins, one of nature's most potent modulators of ion channels and G protein-coupled receptors (GPCR). Combining a knottin with an antibody's advantageous drug properties, we are developing transformative treatments that reach new levels of specificity and durability for patients with ion channel and GPCR-driven diseases. Initially focused on immunological diseases, heart disorders and chronic pain, our pipeline of proprietary Knot Body® molecules will access targets that have long remained beyond the reach of biologics.

Situated at Unity Campus in Cambridge, UK, Maxion Therapeutics fosters a dynamic and forward-thinking work environment underpinned by our scientific founders, who are trailblazers in antibody engineering. Led by our CEO, Dr Arndt Schottelius, our experienced leadership team boasts a stellar track record. Dr Schottelius has held senior leadership positions, successfully advancing therapeutics from research to late-stage clinical development and building valuable portfolios of drug candidates and pharma partnerships.

Maxion's co-founders, Dr John McCafferty (CTO) and Dr Aneesh Karatt Vellatt (CSO), previously co-founded IONTAS, and together invented Knot Body® technology. Dr McCafferty is also renowned for co-inventing antibody phage display, which contributed to the 2018 Nobel Prize in Chemistry (awarded to his co-inventor Sir Gregory Winter), and co-founding Cambridge Antibody Technology.
