Subsequent Events [Abstract] |
Subsequent Events | Subsequent Events Sangamo BioSciences, Inc. On January 9, 2014, we entered into an exclusive worldwide collaboration and license agreement with Sangamo BioSciences, Inc. (Sangamo) under which both companies will develop and commercialize product candidates for the treatment of two inherited blood disorders, sickle cell disease and beta-thalassemia. The collaboration is currently in the research stage of development. Under the terms of the agreement, we will provide Sangamo with an upfront payment of $20.0 million in cash, with additional payments of up to $300.0 million based on the achievement of certain development and regulatory milestones, plus royalties based on sales. Under this arrangement, Sangamo will be responsible for identifying a product candidate for the treatment of beta-thalassemia and advancing that candidate through a completed Phase 1 human clinical trial, at which point we will assume responsibility for development. We will jointly develop a sickle cell disease candidate through the potential filing on an investigative new drug application, after which we will assume clinical responsibilities. We will lead the global development and commercialization efforts and Sangamo will have the option to assume co-promotion responsibilities in the U.S. Completion of the transaction is subject to customary closing conditions, including antitrust clearance in the U.S. under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.
