Ed’s stories explore prescription drug pricing, affordability and access, as well issues surrounding patents, litigation, and legislation. He is also the author of the morning Pharmalittle newsletter and the afternoon Pharmalot newsletter.In a setback for Merck, a Dutch court ruled that the company infringed on a patent pertaining to a subcutaneous formulation of its Keytruda cancer treatment and was ordered to halt manufacturing and marketing the medication in several European countries, including France, Italy, Sweden, Switzerland, and the Netherlands.
