The rise of rare diseases has become lucrative for drugmakers. They usually charge higher prices for treatments that serve small patient populations. According to the US National Institute of Health, around 30 million Americans are living with rare diseases. This disease epidemic has prompted a number of pharmaceutical companies to focus on the lucrative rare disease market.
