Teva vs Biogen. The battle on MS field.

Teva Pharmaceutical Industries Ltd, which makes the market-leading multiple sclerosis drug Copaxone, has filed a petition with the U.S. Food and Drug Administration that could, if granted, delay entry to the market of a rival drug developed by Biogen Idec

Teva's petition asks that the FDA not approve any new multiple sclerosis drug until its safety has been evaluated by a panel of outside advisors, and said it had uncovered "troubling information" on a publicly accessible website about the safety of Biogen's drug, BG-12.

Israel-based Teva said the information showed that kidney changes were observed after repeated administration of BG-12 in mice, rats, dogs and monkeys. The company suggested that as a result, "there is a substantial probability the risk is applicable to humans as well."

It is more common that Big Pharma share the market – the market is so huge that there should be a place for everybody. In the present case we have more interesting scenario!
