FDA Approves Zarxio, First Biosimilar Drug

From www.nytimes.com – March 6, 2015

The approval paves the way for alternatives to an entire class of complex and costly drugs to go on the market.

Most brand-name drugs eventually lose their patent protection, opening the market to lower-priced generic products, but until now biosimilar drugs have been insulated from the competition of cheaper copies. The FDA has now finally approved the first biosimilar for use on the American market.
A quite significant decision as it opens the door to a new class of potentially cheaper drugs made using living cells and not synthesized from chemicals like typical drugs.
