Item 1.01. Entry Into a Material Definitive Agreement.

On December 31, 2011, Regeneron Pharmaceuticals, Inc. (the “Company”) entered into a non-exclusive license and partial settlement agreement (the “Agreement”) with Genentech, Inc. (“Genentech”) that covers making, using, and selling EYLEA™ (aflibercept) Injection for intravitreal injection in the United States for the prevention and treatment of human eye diseases and disorders. Under the Agreement, the Company received a non-exclusive license to certain patents relating to VEGF receptor proteins, known as the Davis-Smyth patents, and certain other technology patents owned or co-owned by Genentech. The Davis-Smyth patents are the subject of patent litigation between the Company and Genentech now pending in the United States District Court for the Southern District of New York. The Agreement does not cover any non-US patent rights or non-US patent disputes, and does not cover any use of aflibercept other than for prevention and treatment of human eye diseases and disorders. Patent litigation is continuing with respect to matters not covered by the Agreement. The Agreement provides for the Company to make payments to Genentech based on U.S. sales of EYLEA through May 7, 2016, the date the Davis-Smyth patents expire. The Company will make a lump-sum payment of $60 million once cumulative U.S. sales of EYLEA reach $400 million. The Company will also pay royalties of 4.75% on cumulative U.S. sales of EYLEA between $400 million and $3 billion and 5.5% on any cumulative U.S. sales of EYLEA over $3 billion.

These statements concern, and these risks and uncertainties include, among others, the nature, timing, and possible success and therapeutic applications of EYLEA and Regeneron’s product candidates and research and clinical programs now underway or planned, the likelihood and timing of possible regulatory approval and commercial launch of Regeneron’s late-stage product candidates, determinations by regulatory and administrative governmental authorities which may delay or restrict Regeneron’s ability to continue to develop or commercialize EYLEA and other products and drug candidates, competing drugs that may be superior to EYLEA and Regeneron’s products and drug candidates, uncertainty of market acceptance of EYLEA and Regeneron’s products and drug candidates, the possibility of EYLEA sales meeting or exceeding any of the cumulative U.S. sales targets triggering payments to Genentech described in this news release, unanticipated expenses, the availability and cost of capital, the costs of developing, producing, and selling products, the potential for any license or collaboration agreement, including Regeneron’s agreements with Sanofi and Bayer HealthCare, to be canceled or terminated without any product success, and risks associated with third party intellectual property and pending or future litigation relating thereto.
