Achillion Accused of Misleading Investors Regarding Viability of Sovaprevir 

Shares of Achillion fell $4.22 per share, or more than 58%, on September 27,
2013, after the company disclosed that the U.S. Food and Drug Administration
("FDA") continued its clinical hold on sovaprevir, its premier investigative
drug for the treatment of hepatitis. This steep decline comes just two months
after Achillion experienced an initial 25% decline per share on the
announcement that the FDA instituted the clinical hold on July 1, 2013.

According to the complaint, defendants made false and/or misleading statements
and failed to disclose material adverse facts about the company's business,
operations, and prospects, including the safety and suitability of sovaprevir.
Defendants failed to inform investors that sovaprevir did not interact well
with other drugs commonly administered to treat hepatitis and/or HIV, and
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.
