What are the key financial results reported by Regeneron in this filing?

What is the significant safety information provided about EYLEA?

Regeneron reported to the FDA that since EYLEA's commercial launch in November 2011, approximately 30,000 injections had been administered in the U.S. Reports of sterile intraocular inflammation occurred at a rate of about 0.05% per injection, driven mainly by a cluster at one practice. Excluding that practice, the rate was about 0.01%. The company stated this incidence is consistent with other anti-VEGF agents and clinical trial data, suggesting external factors, not the drug itself, are likely the cause.

Is the rate of sterile intraocular inflammation with EYLEA a cause for concern?

Regeneron indicated that the reported incidence of sterile intraocular inflammation is within the expected range seen with intravitreal injections of similar drugs and during clinical development. The company also noted the lack of association with any single drug lot and its belief that external factors are responsible, which suggests the issue is manageable and not indicative of a widespread drug defect.

Where can I find more detailed information about the adverse events and financial results?

More detailed information regarding the financial and operating results for the period ending December 31, 2011, can be found in the press release attached as Exhibit 99.1.
