San Diego, CA -- (SBWIRE) -- 10/14/2013 -- An investor, who purchased shares of Achillion Pharmaceuticals, Inc. (NASDAQ:ACHN), filed a lawsuit in the U.S. District Court for the District of Connecticut over alleged violations of Federal Securities Laws by Achillion Pharmaceuticals, Inc. in connection with certain allegedly false and misleading statements made between April 21, 2012 and September 27, 2013, including the safety and suitability of its premier investigative drug for the treatment of hepatitis, sovaprevir.

The plaintiff claims that the defendants failed to inform investors that sovaprevir did not interact well with other drugs commonly administered to treat hepatitis and/or HIV.

Investors who purchased shares of Achillion Pharmaceuticals, Inc.

According to the complaint the plaintiff alleges on behalf of all persons or entities who purchased or otherwise acquired securities of Achillion Pharmaceuticals, Inc. (NASDAQ:ACHN) between April 21, 2012 and September 27, 2013, that Achillion Pharmaceuticals, Inc. and certain of its officers and directors violated federal securities laws pursuant to Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder.

More specifically, the plaintiff alleges that the Company misled investors to believe that even though patients in the Company's clinical trials for sovaprevir had elevations in liver enzymes, that these liver enzymes elevations were transient and returned to baseline values and were attributable to non-drug-related factors.

Achillion Pharmaceuticals, Inc said that the FDA response indicated that, while Achillion Pharmaceuticals' submission addressed all issues noted in the FDA's June 29, 2013 letter, the FDA concluded that the removal of the clinical hold is not warranted.

Shares of Achillion Pharmaceuticals, Inc dropped from $7.40 per share on Sept. 27, 2013, to $2.40per share on Oct. 9, 2013.
