NEW YORK, Sept. 25, 2013 /PRNewswire/ -- Pomerantz Grossman Hufford Dahlstrom & Gross LLP is investigating claims on behalf of investors of AMAG Pharmaceuticals, Inc. ("AMAG" or the "Company")(NASDAQ: AMAG).  Such investors are advised to contact Robert S. Willoughby at rswilloughby@pomlaw.com or 888-476-6529, ext. 237.

The investigation concerns whether AMAG and certain of its officers and/or directors have violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934.  On December 21, 2012, AMAG submitted to the U.S. Food and Drug Administration (the "FDA") a supplemental New Drug Application (the "sNDA") under section 505(b) of the Federal Food, Drug, and Cosmetic Act for Feraheme (ferumoxytol) Injection, 510 mg. The sNDA sought approval for a broader indication for Feraheme for the treatment of iron deficiency anemia in adult patients who have failed or could not use oral iron. On September 23, 2013, the Company received a notification from the FDA stating that, as part of its ongoing review of the Company's sNDA, the FDA has identified deficiencies that preclude discussion of labeling and postmarketing requirements/commitments by September 23, 2013, a target date previously communicated by the FDA in a letter dated March 5, 2013.  On September 25, 2013 the Company announced in an Securities and Exchange Commission Form 8-K filing, information regarding the FDA notification received on September 23, 2013.

On this news, shares of AMAG fell $3.09 per share to more than 11.81% on intraday trading to a price of  $23.07 on September 25, 2013.
