Deal might have been signed a couple of years ago between Pfizer and Brazil. They were just waiting for approval. If you recall, Pfizer gets 60%, so it does not make PLX worth billions. Agreement was for Brazil to manufacture drug itself at a plant in Rio De Janiero over 5 years. Deal was worth $750 million over the 5 years which is about how much Brazil pays for Cerezyme.
Anyway, maybe Brazil and Israel can help turn a profit. Maybe with Brazil drug approval Pfizer might consider the takeover.
