Specifically, Defendants made false and/or misleading statements and/or failed to disclose: (1) that persistent low-grade LFT abnormalities had been observed in the Phase 2 study of imetelstat in ET/PV patients; (2) that there was a potential risk of chronic liver injury following long-term exposure to imetelstat; and (3) that, as a result of the foregoing, Defendants' positive statements about the Company and the prospects for imetelstat lacked any reasonable basis and/or were materially false and misleading at all relevant times.
