Takayasu Arteritis: It's Time to Work Together
In the United States, the Orphan Drug Act of 1983 defines a disease as rare if it affects fewer than 200,000 people. In the United States, there are more than 6,800 rare diseases that affect up to 30 million people. With an estimated incidence of 2 to 3 cases per million people in the United States1, Takayasu arteritis (TA) easily meets this definition. As such it suffers from the challenges inherent to its limited patient base.
