Only 10-15 first-in-class new medicines are approved each year by the global pharmaceutical industry for all diseases, of which less than a third is for rare (orphan) diseases. The drug discovery processes to identify rare and common diseases are similar, suggesting it will be impossible to discover new drugs for even a small fraction of the rare diseases using the current paradigm. Different approaches are required to address this large unmet medical need.
