The Firm is investigating potential claims on behalf of investors of Zafgen, Inc. investors ("Zafgen" or the "Company") (Nasdaq: ZFGN) concerning the Company’s and its officers’ possible violations of federal securities laws.

On October 16, 2015, Zafgen disclosed that it received verbal notice from the U.S. Food and Drug Administration that the clinical trials involving beloranib, a drug designed to reduce hunger while stimulating the use of stored fat as an energy source, have been placed on partial hold following the death of a patient enrolled in a beloranib trial. Additionally, news reports allege that the company disclosed that six patients in previous and current trials reported thrombotic adverse events, including blood clots in the legs, and more seriously, in the lungs, and that all six patients were treated with beloranib.

On this news, the Company’s stock price fell as much as $8.50, or 40%, during intra-day trading on October 16, 2015.
