The need for proteomic-based biomarkers in the drug development pipeline

Pharmaceutical companies are under increasing pressure to improve their efficiency and returns on drug discovery projects. This is a daunting task considering that the average drug costs approximately one billion US dollars to develop and takes around 12 years from initial discovery to reach the market1. In addition, approximately 70 per cent of drugs fail to recover their research and development costs and around 90 per cent fail to provide a satisfactory return on investment. Therefore, minimising risk is one of the most important aims in pharmaceutical discovery programs today.

There are now efforts to establish standard operating procedures to navigate through these problems and, at the same time, meet the regulatory demands. To facilitate this process, the regulatory health authorities have encour aged the incorporation of biomarkers into the drug discovery pipeline and the Food and Drug Administration (FDA) has called for efforts to modernise and standardise approaches for the delivery of more effective and safer drugs2.

Proteomics is the most applicable tech – nology for implementing biomarker app – roaches in drug discovery given that virtually all existing drug targets are proteins3. Proteomics is a systems approach for the global study of protein expression changes4.
