BOSTON, April 26, 2016 /PRNewswire/ -- Block & Leviton LLP (www.blockesq.com), a securities litigation firm representing investors nationwide, is investigating whether Ironwood Pharmaceuticals (NASDAQ: IRWD) and certain of its officers and directors have violated federal securities laws following the publication today by Phase Five Research of a report entitled "Uncovered: fatal safety issues linked with Ironwood's drug, Linzess".

Ironwood shares were trading down over 10% in early trading on Tuesday following the publication of the report. Among other things, the report alleges that "Contrary to IRWD's claims, Linzess's side effects are not limited to the gastrointestinal (GI) tract," but are instead causing "previously unknown, unreported and unlabeled severe systemic adverse events, including documented cases of rapid weight gain, renal failure, seizures and strokes."
