Maxygen CEO James Sulat said Astellas’ decision to exercise the options represents “another important milestone” in the company’s “ongoing efforts to maximize the value of its portfolio and assets.”

In order for the deal to consummate, which is slated for the second-quarter of this year, the companies must enter into a definitive agreement for the acquisition by Astellas for the preferred units of Perseid held by Maxygen. They must also attain regulatory approvals. Maxygen’s shareholders approved the acquisition in 2009 as part of the joint venture agreement.

Upon close, Perseid will become a wholle-owned subsidiary of Astellas.
