While the potential for precision medicine has excited drug developers and clinicians with the promise of delivering more meaningful therapies to patients, the advent of these medicines has largely come in the area of cancer. As the understanding of the biology of other diseases is better understood, efforts to develop precision medicines are advancing into new areas. We spoke to Rachel Laing, managing director of the life sciences consulting firm Bionest, about the state of precision medicine, what can be learned from the experience in cancer, and what it will take to make precision medicine approaches the way we treat diseases broadly.
