It was, said the company, destined to grow to €50bn by 2015. Sanofi laid out the scale of its ambitions clearly: to be the number one firm in the diabetes market.3 4
The growth in diabetes drug revenue has been caused in part by rising numbers of people with diabetes; partly by more aggressive approaches to glucose lowering; but mainly by increasing unit costs for insulin5—a cost that can be attributed to the use of more expensive recombinant insulin analogues.
Sanofi’s ambition to be, in effect, the dominant force means wresting control from the traditional heavyweights of the insulin world, Novo Nordisk and Eli Lilly. However, health services and individuals across the world are paying the price for this market drive, which has seen more expensive analogue insulins taking the place of cheaper human insulin.
