Item 2.02 Results of Operations and Financial Condition.

       On February 13, 2012, Regeneron Pharmaceuticals, Inc. issued a press release announcing its financial and operating results for the quarter and year ended December 31, 2011. The press release is being furnished to the Securities and Exchange Commission pursuant to Item 2.02 of Form 8-K and is attached as Exhibit 99.1 to this Form 8-K.

Item 7.01 Regulation FD Disclosure.

       On February 13, 2012, Regeneron Pharmaceuticals Inc. (Company) provided the U.S. Food and Drug Administration (FDA) with information relating to adverse events reported to the Company for EYLEA® (aflibercept) Injection since the drug became commercially available in November, 2011. Among other things, the Company reported that since launch approximately 30,000 injections have been administered in the United States, and the Company has received reports of sterile intraocular inflammation following the administration of EYLEA at a rate of approximately 0.05% per injection. This rate was driven primarily by a cluster of events occurring at a single practice with the overall rate, excluding this practice, being approximately 0.01% per injection. The incidence of adverse events of intraocular inflammation reported thus far during commercial use of EYLEA is within the reported incidence in the literature with the intravitreal injection of anti-VEGF agents and other drugs as well as the rate observed during the clinical development program, even accounting for the possibility of underreporting. In addition, the lack of association of these adverse events with a single lot of drug product further led the Company to conclude that factors other than the drug are likely to be responsible for the occurrence of these events. The full letter to the FDA is furnished with this Current Report as Exhibit 99.2.
