Dr. Bertil Lindmark discusses personalized medicine from an industry perspective. He argues that while personalized medicine aims to provide the right prevention and treatment for each patient, applying it to all situations may lead to overly expensive therapies for small patient groups and neglect of broader patient needs. For pharmaceutical companies, the "sweet spot" of personalized medicine is small, requiring a balance between development costs, therapeutic effects, and market size. Effective collaboration is needed between industry and academia to focus efforts on both specific disease areas with high costs and predictability, as well as broader indications where incremental innovation can still be profitable.
