Until October 16, 2015, Zafgen had disclosed only two thrombotic adverse events in one prior clinical trial. On October 14, 2015, Zafgen issued a statement acknowledging the death of a patient in its ongoing Phase 3 study of beloranib. On October 15, 2015, the Food and Drug Administration informed Zafgen that beloranib had been placed on partial clinical hold. Then on October 16, 2015, Zafgen announced that: (i) the patient who died was receiving beloranib – not a placebo; and (ii) there had been four thrombotic adverse events in prior clinical studies of beloranib – two more than previously reported – as well as two additional, previously undisclosed thrombotic events in ongoing studies. If you suffered a loss in Zafgen you have until December 21, 2015 to request that the Court appoint you as lead plaintiff. Your ability to share in any recovery doesn't require that you serve as a lead plaintiff. Levi & Korsinsky is a national firm with offices in New York, New Jersey, Connecticut and Washington D.C.
