Item 8.01. Other Events.

 

On May 4, 2005, Arena Pharmaceuticals, Inc. was granted patent number 03 718 323, entitled “5-HT2C Receptor Modulators,” by the European Patent Office. The patent relates to novel compounds that modulate the 5-HT2C serotonin receptor, which is thought to be involved in the regulation of food intake and may be useful in pharmaceutical compositions for the treatment of obesity. APD356, discovered by Arena, is an orally available 5-HT2C receptor modulator covered under the patent. Arena intends to validate the patent in 31 European jurisdictions, including Germany, France, Italy, the United Kingdom and Spain, as well as Hong Kong.

 

Forward-Looking Statements

 

Certain statements in this Form 8-K are forward-looking statements that involve a number of risks and uncertainties. Such forward-looking statements include statements about the 5-HT2C serotonin receptor’s profile and pharmaceutical behavior and Arena’s intention to validate the European patent covering APD356. For such statements, Arena claims the protection of the Private Securities Litigation Reform Act of 1995. Actual events or results may differ materially from Arena’s expectations. Factors that could cause actual results to differ materially from the forward-looking statements include, but are not limited to, the success of Arena’s research and clinical studies and Arena’s ability to obtain and defend its patents. Additional factors that could cause actual results to differ materially from those stated or implied by Arena’s forward-looking statements are disclosed in Arena’s filings with the Securities and Exchange Commission. These forward-looking statements represent Arena’s judgment as of the time of the filing of this Form 8-K. Arena disclaims any intent or obligation to update these forward-looking statements, other than as may be required under applicable law.
