FDA approves world’s most expensive drug at $2.1M

A new drug to treat spinal muscular atrophy (SMA) approved by the Food and Drug Administration (FDA) on Friday will come with a price tag of $2.1 million, making it the most expensive medicine in the world. The drug, called Zolgensma, treats SMA, a genetic disease that causes debilitating muscle weakness and paralysis, and is a leading cause of infant mortality. The high price tag is the latest illustration of how innovative drugs, while holding immense promise for improving the lives of the patients who need them, also pose a financial burden on the health care system through their cost.
