Keytruda $17 billion sales in 2021 - patent expires 2028.
For more see Marcus 50662 - published in February, a list of annual sales of monoclonal antibody medications https://www.biospace.com/article/global-top-10-cancer-antibodies-by-sales-2021/
Then Marcus 50663 - ""AvidiMab would also extend the patent life of commercially established programmes. Think about that for a moment!!! Virtually any antibody-based product including the many blockbuster mAbs, each one turning over billions in revenue every year, many with the patent life nearing its end!
""Scancell progresses its new anti-glycan monoclonal antibody (mAb) platform GlyMab™
Initial anti-glycan mAbs from the GlyMab™ platform have now been successfully humanised
Fourth research agreement on Glymab™ platform signed with major European Pharma
Prof Lindy Durrant, Chief Executive Officer, Scancell, commented: "“We believe our proprietary GlyMab™ platform provides a powerful and versatile approach to generating novel antibody drug candidates that bind to sugar motifs, rather than peptide epitopes, found on the surface of glycosylated proteins and lipids that are implicated as drug targets in particular cancers and potentially other diseases. As such, this new platform expands on Scancell’s unique approach to developing innovative therapies for cancer and infectious disease. The Board believes that there are multiple ways to maximise the value of these innovative and proprietary assets, either developing them internally to further value inflection points, develop alongside strategic partners or through earlier stage commercial licences. The fourth research agreement on the Glymab™ platform provides further validation of the commercial potential of this platform.”"

Then Marcus - "AvidiMab could be used to enhance the avidity and potency of virtually any antibody-based product. It would also extend the patent life of commercially established programmes. Hence its appeal could be significant. However, it has only been employed on Scancell programmes and until it has been licensed externally it is difficult to model with any degree of confidence. Consequently, we have adopted a cautious approach, assuming the antibodies using AvidiMab technology have collective peak sales of £8.5bn."
A nice reminder with Marcus' thoughts added. GLA
