Growing market potential for PET radioligands 2010: Lilly acquires Avid Radiopharmaceuticals for an upfront $300 million and $500 million in additional payments 2011: Navidea acquires AZD4694, an amyloid imaging PET ligand from AstraZeneca 10-Jun-14 3
Biologicals are must have for pharma • Radiolabellingwithin development of biologicals very limited • -- lack of generalised radiochemical methodology • Sixout of 21 new approvals by the FDA were for biologicals in 2010 • -- sharewillincrease; typical ambition calls for 30-40% of pipeline • Increasingdemand for ability to monitor, visualise, perform PK studies and implementing personal healthcare • Biosimilars market estimated at USD 4,000 million in 2017 RadTags suggest a new paradigm
FlAsH technology – a fluorescence labeling technology developed for live cell imaging (R Tsien Nobel prize 2008) FlAsH-based protein detection available from
Easily constructed six-amino acid tags The CCPGCC tag can be incorporated by standard techniques • During peptide synthesis • Using Polymerase chain reaction (PCR) • Using cloning vectors commercially available from Life Technologies Gene CCPGCC tag (in frame) Promotor Expression vector
RadTags enable radiolabelling using different isotopes at the same site Precursor for 18F, 121I, 125I, 131I, Precursor for 13C, 14C, 11C, 3H, 19F
