Levi & Korsinsky, LLP announces that it has commenced an investigation of Alnylam Pharmaceuticals, Inc. ("Alnylam" or the "Company") (NASDAQ: ALNY) concerning possible violations of federal securities laws by the Company and/or certain of its officers and directors.

On October 5, 2016, citing patient safety concerns, Alnylam announced the Company's decision to discontinue development of revusiran, an investigational RNA interference therapeutic being developed for the treatment of hereditary ATTR amyloidosis with cardiomyopathy. The Data Monitoring Committee of the study informed the Company that the benefit-risk profile for revusiran no longer supported continued dosing, which led the Company to discontinue the study.
