The complaint alleges that during the Class Period, Arrowhead made false and misleading statements and/or failed to disclose: that its drug candidate ARC-520 was fatal at certain doses; that the U.S. Food & Drug Administration was unlikely to approve ARC-520 as a hepatitis B treatment; that the Company overstated the approval prospects and commercial viability of ARC-520; and that as a result of the above, Arrowhead’s public statements were materially false and misleading at all relevant times. On November 8, 2016, Arrowhead revealed that the U.S. Food & Drug Administration will be placing a clinical hold on its Heparc-2004 clinical study of ARC-520, likely due to deaths at the highest dose of an ongoing non-human primate toxicology study. When this news was announced, shares of Arrowhead fell in value, causing investors harm.
