Emergent BioSolutions has inked a deal to acquire the Protein Sciences Corporation assets for up to $75 million. The move is part of Emergent's strategy to expand its product portfolio with a drug candidate focused on infectious disease. Currently, most of Emergent's business comes from government contracts for biodefense. Emergent will acquire PSC's ongoing operations, including FluBlok, a Phase III recombinant influenza vaccine candidate, and certain other assets. "The acquisition of FluBlok is consistent with Emergent's strategy of expanding its product portfolio with a vaccine candidate focused on a major infectious disease," said Fuad El-Hibri, Emergent's CEO. The company recently bought rival VaxGen's anthrax vaccine business.
