He discusses the development of an easy-to-inject insulin system by Novo at the same time Lilly developed much purer insulin. The latter was a huge engineering/scientific breakthrough by Lilly that made insulin less likely to be rejected by deriving it from humans rather than pigs. Novo developed an easy-to-inject insulin pen system that had the same old 1/10K rejection rate, but gained market share.
