Study Finds Arthritis Drug Enbrel Overpatented, Overpriced in US

Initiative for Medicines, Access & Knowledge (I-MAK) released a new study yesterday showing that the rheumatoid arthritis drug Enbrel has been overpatented by drugmaker Amgen, which has filed a total of 57 patents on the drug in the United States. Together, these patents were said to delay market competition by 39 years, rather than the standard 20 years for one patent. The study found that this market exclusivity for Enbrel resulted in US$ 8 billion dollars in sales in 2017 alone.
