Pharmaceutical R&D in the spotlight: why is there still unmet medical need?

Huge amounts of money and knowledge have been poured into biomedical research for decades. Yet, in some disease areas next to no progress has been made in providing medical treatment. Importantly, it is not only neglected diseases where unmet medical need remains, but many diseases of 'rich' countries are also affected. Occasionally, new therapies exacerbate the medical need gap, such as in cancer. Our paper discusses some of the reasons why this might be and why all of society needs to find solutions to address unmet medical need.
