SHAREHOLDER ALERT: Pomerantz Law Firm Investigates Claims On Behalf of Investors of Achillion Pharmaceuticals, Inc. - ACHN

NEW YORK, Sept. 30, 2013 /PRNewswire/ -- Pomerantz Grossman Hufford Dahlstrom & Gross LLP is investigating claims on behalf of investors of Achillion Pharmaceuticals, Inc. ("Achillion" or the "Company") (NASDAQ: ACHN).  Such investors are advised to contact Robert S. Willoughby at rswilloughby@pomlaw.com or 888-476-6529, ext. 237.

The investigation concerns whether Achillion and certain of its officers and/or directors have violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934.  On September 27, 2013, Achillion announced that the Company received a response from the U. S. Food and Drug Administration (the "FDA"), on the clinical hold related to sovaprevir, the Company's NS3 protease inhibitor. The FDA response indicated that, while the Company's 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.

On this news, shares of Achillion shares fell $4.30 per share, more than 59.53% on intraday trading, to a price of $2.94 on September 30, 2013.
